Sorghum (Jovar), Sorghum. Methods of application, origin of the plant, range, botanical description, cultivation

Sorghum (Jovar)

Sorghum (jowar) is a valuable food crop in dry and hot areas of the tropics, unsuitable for growing wheat, rice and corn. The grain is used to prepare cereals, flour, starch, local beer and alcoholic beverages, puffed sorghum (pop sorghum), sweet fresh grains - a delicious treat. The grain contains from 68 to 82% carbohydrates, 8-15% protein, 2-5% fat, 1,2-3,2% ash and 1-3% fiber. The sweet stems of some species are also used for food (see section Sugar-bearing plants).

In many countries of different climatic zones, sorghum is cultivated as a fodder crop. The grain is used for poultry feed and for the preparation of compound feed, and the green mass is used for fresh feed, hay, haylage, and silage.

When feeding fresh green mass, it should be taken into account that in the young shoots of many fodder varieties there is an increased content of hydrocyanic acid, which gradually decreases with the age of the plants. Therefore, early feeding and grazing of animals on sorghum pastures is not allowed. Dry and ensiled vegetative mass does not contain harmful cyanide compounds. Brooms, brushes, scrapers are made from panicles of some varieties.

World sorghum crops occupy 45,6 million hectares, and the annual grain production is 61,8 million tons. They are mainly concentrated in Asia (42,2%) and Africa (38,5%), but the total production here barely exceeds half of the world collection. This is due to the low crop yield (from 0,3 to 1,5 t/ha) in most sorghum growing countries of these continents: India, Vietnam, Pakistan, Sudan, Nigeria, Burkina Faso, Ethiopia, Tanzania, Somalia, etc.

Sorghum crops in America are relatively small (17%), while the annual grain harvest exceeds 40% of world production. It is obtained mainly from the USA, Mexico and Argentina, where the grain yield is from 2,9 to 4,4 t/ha. In addition to these countries, culture is common in Venezuela, Colombia, Brazil, and Haiti. It occupies significant areas in Australia and small in the countries of Southern and Eastern Europe.

Sorghum belongs to the genus Sorghum, which was cultivated in Ethiopia more than 3 thousand years BC. e. It is believed that from there the culture came to India at the end of the 2nd or the beginning of the 1st millennium BC. e., and later moved to Central Asia. In Europe, sorghum began to be cultivated only in the XNUMXth century, and in America - in the XNUMXth century.

According to the botanical classification, the genus Sorghum includes 31 cultivated species. Most of the species are natives of the African continent. Here Guinean sorghum (Guinean corn) is cultivated for grain - S. guineense Stapf, Ethiopian (kaffir corn) - S. caffrorum Beauv, Sudanese (feterita) - S. caudatum Stapf, grain (durra, durro) - S. durra (Forsk) Stapf (also grown on other continents).

Sugar sorghum - S. mellitum Snowd., bird corn - S. drummondii (Steud.) Millsp. et Chase, Sudanese grass - S. sudanense (Piper) Stapf and Negro (beer) sorghum - S. nigricans (Ruiz et Pavon) Snowd. In Southeast Asia, mainly in India, grain sorghum species predominate - white durra (jugara) - S. cernuum Host (also cultivated on all other continents), kaoliang - S. nervosum Bess, et Schult., mainly in China , and other uses. Among them, cute - S. subglabrescens Schweinf. et Ascers (cultivated on all continents), shell - S. roxburghii Stapf (grain and fodder), sugar - S. bicolor (L.) Moench (fodder and food), broom - S. dochna (Forsk.) Snowd. (technical and feed).

Sorghum (Jovar)

According to the economic classification, sorghum is divided into 5 groups: grain, sugar (feed and food), pasture, technical and special (for starch production, pop sorghum).

Most sorghum species in adulthood are erect, tall, powerful plants with a perennial, but more often one-year development cycle. From emergence to 3-4 leaves, when secondary roots begin to form, sorghum grows very slowly and does not tolerate soil contamination well.

Tillering begins after the formation of 5-6 leaves, and in grain varieties it is weak (1-4 shoots), while in fodder silage varieties it is medium, and in pasture varieties it is strong (up to 50 or more shoots). In the latter, after mowing or grazing by animals, new shoots grow - ratuna.

The growth of stems in height begins after the formation of 7-8 leaves (exit into a tube or stalking). The stems quickly lengthen and thicken, filling with a juicy and sweet core in fodder varieties. In grain sorghum, the stems are dry, spongy, growth is weaker, and the height of breeding varieties and hybrids does not exceed 1,5 m.

Stem growth ends after sprouting or the appearance of an inflorescence (panicle). At the same time, flowering begins, which lasts 7-8 days. Panicles of sorghum vary in size and density, they are straight, drooping, bent, cylindrical, pyramidal or round in shape. Spikelets are located in pairs on the branches, having one flower each - bisexual and male, at the ends of the branches there are 3 spikelets, including 2 male ones. Cross-pollination with the help of the wind, self-pollination is partially present. The flowering and maturation of the panicle goes from top to bottom.

The fruit of sorghum is a small grain, having a mass of 1000 grains from 20 to 45 g. The color is white, yellow, red, brown. Caryopses are naked (in grain forms), but more often membranous, covered with flowering and spikelet scales. In membranous grains there are bitter glycosides. The endosperm is hard or horn-shaped on the outside, and white and powdery on the inside. Depending on the ratio of these layers and filminess, sorghum grains (seeds) during the germination period require from 37 to 55% of water in relation to the dry mass. If there is enough water and the temperature reaches 26-30 ° C, then shoots appear quickly.

When the temperature drops to 8-10 ° C, the seeds germinate very poorly and slowly. Frosts cause damage or complete death of seedlings, they are especially dangerous during the flowering period of plants. This should be taken into account when placing sorghum in the subtropics and mountainous areas of the tropics.

The optimal thermal regime for sorghum from the beginning of stalking to ripening is created at an average air temperature of 27 to 32 °C with a minimum of 14-15 °C. To obtain good yields in optimal terms, early-ripening varieties should receive at least 2000-2300 ° during the growing season, late-ripening - 2400-3000 ° (with a heat level of at least 10 °). In addition to the fact that sorghum is an exceptionally thermophilic plant, it is also the most drought-resistant. Among field crops, there is almost no equal to it in terms of its ability to endure long droughts. No wonder sorghum is called the "camel" among the plants of the world.

In the savannas of West Africa, it is grown mainly in areas with low air humidity and an annual rainfall of 300 to 500 mm. In India, the sorghum belt is located in areas with a long dry season, where precipitation mainly falls from June to early October in the amount of 400 to 1000 mm per year. Here, more than 60% of sorghum is grown in the summer (kharif) season, the rest - in the winter (rabi), and practically without irrigation (about 4-5% of sorghum crops are irrigated).

Sorghum (Jovar)

The high drought resistance of the culture is associated with the peculiarities of the root system, which already in the first phases grows vigorously, significantly ahead of the above-ground mass. Moreover, all 3 types of roots grow and work: germinal (primary), nodal (secondary) and aerial, formed in the stem phase from the lower aerial nodes of the stem. Nodal roots have the ability to break through a dry layer of soil and penetrate to a depth of 2 m or more, reaching wet horizons.

During severe droughts, a protective silicon layer forms in the roots, protecting them from drying out. The wax coating on the stems and leaves of plants plays the same role. In addition, the evaporating surface of the leaves is about half that of corn, and due to the xerophytic structure, they do not spend excess water on their cooling. For the formation of a unit of dry matter, sorghum consumes 15-20% less water than corn. If even a little water remains in the soil, the crop continues to grow despite extreme heat, low air humidity and dry winds. When the soil dries up completely, the plants fall into a state of dormancy, stop growing and developing, and after precipitation, they again switch to active life.

Despite its high drought resistance, sorghum responds well to irrigation, increasing the grain yield by several times, especially on fertile structural soils with good water-retaining capacity and neutral reaction.

Sorghum can grow in a variety of soils, from the heaviest and even waterlogged to poor, light, depleted by years of use. It is grown on both acidic and alkaline and even saline soils unsuitable for most crops. In India, sorghum rabi is sown on medium loamy deep black cotton soils, and kharif is sown on light soils (see section "Corn"). In the African sorghum belt, alluvial fertile land along rivers and streams is considered the best for cultivation.

The time from sowing to harvesting of grain sorghum is from 90 to 190 days and more. It depends primarily on the varieties. Among the local tropical varieties, short-day forms are more common, for which the optimal solar illumination is 10-11 hours per day. A decrease and especially an increase in this period greatly slows down the development of plants. However, there are forms that react poorly to the length of the day. The photoperiodic reaction of breeding varieties and hybrids depends on the places of their zoning.

The main direction in the selection of rainfed grain sorghum in the semi-arid tropics and dry subtropics is the breeding of drought-resistant varieties and hybrids. They should be highly productive (more than 3 t/ha), short-stemmed, resistant to loose smut and shedding, and for areas with a short rainy season - early ripening. The latter direction is very important for the deployment of sorghum in the highlands of East Africa and the highlands of Latin America. For these conditions, cold-resistant and early-ripening varieties are needed. Irrigated sorghum varieties should have higher productivity (6-10 t/ha), low bushiness, resistance to lodging, diseases and pests, positive response to thickening, high agrobackground and intensive cultivation methods.

In the majority of sorghum growing areas, where small peasant farms prevail, sorghum farming practices are primitive. In Africa, this is primarily due to the shifting system of farming, in which grain crops predominate, and soil fertility increases naturally, without human intervention - under the influence of forest growth, fallow or fallow. Here sorghum is grown after fallow, peanuts, cotton, yams, sweet potatoes. When placed after fallow, especially without fertilizers, low yields are obtained.

With an increase in the level of agriculture, fallows are replaced by green manure fallows, where crops are grown for green manure, or crops of perennial grasses. Examples of such crop rotations: sorghum - African millet - cowpea - African millet - sorghum - green manure fallow; peanut - sorghum - sorghum - fonio - cowpea - African millet - green manure fallow; cotton - sorghum - peanuts - African millet - peanuts - forage grasses.

In India, 2-3-year crop rotations are practiced, in which sorghum alternates with cotton, peanuts, chickpeas, and safflower. Here, its joint crops with mungo, mung bean, cowpea, urd, African millet and other crops are very common. Permanent crops of sorghum are very rare, as they greatly deplete the water and food reserves of the soil, plants often suffer from bacteriosis, are clogged with malicious semi-parasitic weeds from the genus Striga and other types of weeds.

In the tropics, sorghum is planted at various calendar times, usually associated with rainfall. In Africa, where rainfed crops predominate, it is carried out more often in May-June, that is, at the beginning of the rainy season. Preliminary preparation of the soil is mostly primitive. During the dry season, peasants loosen their plots with hoes or graze sheep and goats on the dry stubble residue of the previous crop, while the animals fertilize the soil and cover up scattered seeds.

In West Africa, on poor or damp soils, after the flood waters have drained, ridges or heaps of earth are made, into which seeds are sown at a distance of 30-60 cm, 3-5 pieces each. into the hole. Sometimes, up to 7-10 t/ha of manure and mineral fertilizers are applied for pre-sowing treatment. For example, in Ghana, during this period, 15 kg / ha of the active substance of nitrogen, phosphorus and potassium are given, and 45 days after sowing, another 40 kg of nitrogen are added to top dressing. In some parts of West Africa, sorghum is transplanted. To do this, at the end of August, the seeds are sown in the nursery, seedlings are obtained, which are transplanted into the field in October.

In India, the main sowing time for sorghum is in July. Rabi is sown from November to January. Before sowing local varieties, manure is applied and plowing or small-scale cultivation is carried out, often with the help of animals. Sowing by broadcast or seeders with row spacing of 30-45 cm. For high-yielding varieties and hybrids, mineral fertilizers (N, P30-40) are used, half of which is planted for deep plowing or pre-sowing cultivation, the rest is given for top dressing 30-40 days after sowing. On heavy soils, the entire dose of fertilizer is applied before sowing.

To obtain the optimal sowing density - 180-200 thousand plants/ha - seeds in the amount of 10-12 kg/ha are sown according to the scheme 45-60X10-15 cm, using precision seeders. In Latin America, the best time for sowing sorghum is from August to October. In Mexico, wide-row furrow sowing is used with the introduction of 78 kg/ha of urea and 174 kg/ha of triple superphosphate in the preparation of furrows.

In subtropical regions, the timing of sorghum sowing is spring, when the soil warms up to 15-20 ° C - approximately 7-10 days after sowing corn. When preparing the soil, they practice deep autumn (autumn) plowing up to 25-35 cm, early spring harrowing, 1-2 cultivations and careful leveling of the soil surface, especially on irrigated crops, under which high doses of mineral fertilizers are applied. Grain sorghum, when irrigated along the furrows, is sown with row spacing from 60 to 90 cm, bringing the sowing density to 160-200 thousand plants/ha, and dwarf varieties - up to 250-400 thousand plants/ha. Sowing depth on loose and moist soils is 2-3 cm, and on dry soils - 5-6 cm.

Crop care starts early. In the early stages, it is very important to avoid blockage, because due to the slow growth of sorghum, it has little competition with weeds. In Africa and India, weeds are almost universally weeded by hand, and seedlings are thinned at the same time. Only on large farms, in cooperative associations and state agricultural enterprises, when growing intensive varieties and hybrids, mechanized and chemical methods of controlling weeds, diseases and pests are used. The latter is also characteristic of sorghum growing in America and Australia.

On crops of upland sorghum, 2-3 inter-row treatments are carried out, on irrigated crops there may be more. Weed control is also carried out with the help of herbicides. The choice of herbicides for the protection of sorghum is limited by the fact that the crop is very sensitive to the drugs used. The most suitable soil (basic) herbicide is atrazine. It is effective against monocotyledonous and dicotyledonous weeds. It is applied at a dose of 4-6 kg/ha 2-3 months before sowing.

To destroy atrazine-resistant perennial and annual cereals and some dicotyledonous weeds, additional treatment of vegetative sorghum (3-6 leaves) with 2,4-D herbicide (amine, sodium salt) at a dose of 0,5-0,75 kg/ha is used. V. Disease and pest control is similar to that described in the Corn section. Against the most dangerous specific pest - sorghum mosquito (Contaria Sorghicola) in Mexico, lorsban 408E (1 l / ha), diazinon (25%, 1 l / ha) or sevin (80%, 1 l / ha) are used.

Among other maintenance operations in dry, non-irrigated areas, soil mulching with organic matter is practiced. For example, in India, row-spacing mulching of fodder sorghum with rice straw (6 t/ha) resulted in a 13-22% increase in green mass yield due to reduced soil overheating and increased plant water and fertilizer nitrogen use efficiency.

In the dry subtropics of North Africa, America, Australia, the Near and Middle East and in limited areas in the tropics of Southeast Asia, where the annual rainfall is below 450 mm, sorghum is irrigated 3-4 times during the growing season from tillering to seed filling, spending for each irrigation from 500 to 800 m3 of water per 1 ha (irrigation rate). If there is not enough water, one watering is done after sowing so that the seeds germinate and give good shoots. For irrigation conditions, short-stemmed, non-lodging varieties are suitable, which respond well to thickening and high agrobackground.

In the United States (Nebraska and Texas), the cultivation of such varieties with frequent regular irrigation during the dry season (2 times a week at 500 m3/ha) provides a grain yield of 9,5-10,7 t/ha. In the south of France, grain yields of short-stemmed sorghum varieties range from 8,6 (early-ripening - 350-450 thousand plants / ha) to 10,8 t / ha (late-ripening - 200-300 thousand plants / ha), growing them on a high agricultural background and watering 2-4 times during the growing season - from the beginning of stemming to seed filling.

In India and most of Africa, grain sorghum is harvested by hand. Panicles are cut alone or together with stems, tied into bunches and dried in places inaccessible to birds, rats and especially insects, which damage sorghum more than any other grain crop. Threshing is carried out with sticks, after which the grain is winnowed and stored in bins or bags.

Short-stemmed, uniformly ripening varieties are suitable for mechanized harvesting. It is carried out in a separate way, using headers and grain harvesters with pick-ups or sorghum harvesters that cut panicles at a height of 0,6-2,5 m. In addition, converted grain or silo combines are used, which provide both panicle cutting and stem harvesting. Cut panicles are dried and threshed at stationary points.

Plants are harvested for silage by forage harvesters at the end of the milky - the beginning of the wax ripeness of the grain, when the stems contain the maximum amount of sugar. Sorghum crops mixed with cowpeas, soybeans, beans or other legumes, when used for silage, are mown during the flowering period - the beginning of the formation of beans, when the feed mixture is richest in protein and is well ensiled. Harvesting for green fodder and hay is carried out in several steps. The first mowing is done before the plants are sprouting, the subsequent ones - as the vegetative mass grows.

Sorghum. Botanical description of the plant, areas of growth and ecology, economic importance, applications

Sorghum (Jovar)

How to imagine sorghum? As easy as pie. Take ordinary brooms, which are brought from the south. This is broom sorghum. Turn the broom upside down - that's how it grows, only it can be much higher. And for a broom, only the panicle itself is cut off. On it, in some places, red grains are still preserved, similar to millet (a relative of millet), if the broom is new.

Sorghum grains, like millet, are a favorite food of chickens and birds in general. However, not only poultry loves sorghum and millet. Sparrows, for example, often fall in armadas on sorghum and millet fields.

In particular, they annoy the experimental stations, where different varieties are sown on small plots.

Scientists have tested different methods of anti-sparrow protection. They came to a consensus: the best means is a cracker cannon. This is a piece of iron pipe with a simple device. Charge it with carbide. A blank shot is fired.

Sparrows fly away. It seems that this is the first case of practical application of the saying: "From a cannon to sparrows." It is now up to the industrial production of anti-sparrow guns.

Once upon a time, they tried to make sugar from sorghum. In Russia, in the middle of the last century, someone published an article in one of the magazines, where he described in detail how he squeezed the juice, evaporated it in a tablespoon and got the usual snow-white crystals. There were immediate followers. One of them immediately planted two acres (more than two hectares!). Juice squeezed out, but did not receive crystals. In addition, he also got into trouble. In those years, there was a saying in vogue: "Sorghum feeds both man and the earth." Believing in the saying, the poor fellow thought that at least the soil would improve.

Instead, the opposite happened. Sorghum dug into the virgin steppe so tightly that it was not easy to pull out the roots from there. The usual plow in those years broke. I had to take up a shovel, digging from four sides. Only then did the plant give up. But try to extract from the earth all 42 thousand roots that remained on two acres! Yes, and that would be half the trouble.

The torn roots then lay for a long time, littering the arable land, because under the steppe sun they did not rot at all.

So, sorghum is not yet very suitable for sugar production. The sugar cane remains. It really looks a bit like our usual reed that grows in wet places, along the shores of lakes and the outskirts of swamps. Long, narrow, like all cereals, leaves a meter or a half long. The same cranked knotted trunk. The same underground rhizome. Panicle - on top. And as high as our reed, up to six meters.

difference in stem thickness. He's like a pole in sugar. And stronger. In Cuba, the reed accompanies man everywhere. He wanted sweets, went off the road, cut off a piece of the stalk with a penknife and suck it like candy.

The sugar is melting. What remains is inedible wood, similar to sawdust. She is spit out. Macateros - cane cutters - do it even easier.

When thirsty, they take a reed pole, break it in half with a sharp blow, raise it above their heads and expose their mouths. Juice flows like from a bottle. They say that in the heat it quenches thirst. And most importantly, hygienic. There is, however, an inconvenience. You must immediately rinse your mouth with water, otherwise the teeth quickly decay, like those who suck a lot of candies.

Bombay is different. Huge meat grinders, the size of a desk, are set up on the streets. Nearby lies a pile of poles, like brushwood collected in the forest. At the first request, the seller puts the pole into the mouth of the meat grinder. There is a crunch, you substitute a glass, and juice is filtered into it. Of course, you also need to rinse your teeth.

Sorghum (Jovar)

Reed is a perennial plant. Once you plant a cutting, then harvest for three or four years. The trunks are cut down, and in their place new ones appear from the rhizome. Sometimes the plantation works for 10 years. The only inconvenience during cleaning is the leaves. They interfere. Sometimes they are simply burned on the vine. What such an event leads to, I was convinced on the Fiji Islands. In the morning I went out into the air from the hotel and was stunned. Ahead, on a green plain covered with cane plantations, a fiery whirlwind raged. The smoke rose like a dark rope to the sky and there spread into an ominous cloud.

- They burn reeds, - the guide explained. - Trunks do not burn. Then they are easier to process.

The mountains were blue in the distance. I expected to see lush rainforests on them. And take a photo for memory.

After breakfast we went on an excursion past those mountains. We drove a hundred miles. The mountains were not green, but black. Everything burned down on them. All tropical forests. The fire from the plantation went into the forest.

Of course, the reed itself often suffers from various adversities. The first is hurricanes. Most of all, it seems, goes to the island of Mauritius. History has preserved the memory of the hurricane of 1892. On April 29, the wind reached a terrifying speed of 103 miles per hour. The whirlwind swept through the very center of the island. The reeds cracked and bent almost to the ground. Then the hurricane turned sharply and blew in the opposite direction at the same crazy speed. This reed could not stand it. Half of the harvest is gone.

Historians have calculated that in half a century Mauritius was defeated 42 times. There is a hurricane almost every year.

If only it were limited to hurricanes. In addition to them, earthquakes. 1934 Catastrophic earthquake in Bihar. The cane was not particularly affected, but the factories collapsed. We had to transport raw materials to other places. Even worse are the pests. The list of their invasions made a long list. That invasion of mice in Egypt, then caterpillars in Sicily, then outrages of ants in Cuba and Puerto Rico.

But perhaps the most terrible story happened to the reed at the beginning of our century in the Hawaiian Islands. Suddenly the sugar cane began to die from root rot.

The culprit of the disaster was the mushroom Veselka reddish. It resembles ordinary edible mushrooms in that it has a stem and a cap. And although the design of this mushroom is different, outwardly everything is very similar. Only the cap is covered with stinky slime to attract flies. The chief medical officer of the plantation was horrified when he saw how many Veselok settled under the cane bushes. In addition, a myriad of flies appeared, attracted by the nauseating "aroma" of mushrooms. News of the mushroom invasion came from all over the islands.

The planters realized that the fate of the cane had been decided. They began to prepare to replace it with another culture. However, the mushrooms disappeared as suddenly as they appeared. Why they so suddenly multiplied and what made them disappear is still a mystery. Since then, Veselka has not been heard from again. But the anxiety still remained.

What if the fungus reappears? What if some other parasite emerges from oblivion and destroys the reeds?

Eternal anxiety for the reed exhausts the nerves. In the 80s, planters were fearful that the cane was degenerating. There are good reasons for concern: they have been propagated by cuttings for hundreds of years. Seeds - never. Of course, it cannot be said that the reed does not bloom. In Colombia, its panicles are visible at any time of the year. But the seeds do not germinate - and that's it! How many attempts have been made - all in vain. Finally, at the end of the century, the first shoots were received in Java. The seed generation is more reliable, more stable and stronger against pests.

The history of sugar is as old as the world. And cane too. But in recent years, the fate of the reed has changed dramatically. Mankind remembered that sugar can be turned into alcohol, and alcohol is an excellent fuel, which, by the way, almost does not clog the environment. At the end of World War II, alcohol-powered vehicles were already operating in Cuba. Therefore, Brazil is now trying to convert vehicles to alcohol. It's only slightly more expensive than gasoline. Fuel is tight in Brazil, and cane is growing so fast... True, economists are worried: will there be enough sugar to eat if Brazilians squander it in car engines?

Sorghum (Jovar), Sorghum. Tips for growing, harvesting and storing

cultivated and wild plants. Legends, myths, symbolism, description, cultivation, methods of application

Sorghum (Sorghum) is a plant that is used as a fodder crop, as well as for the production of syrup, starch and alcohol. In some regions of the world, sorghum seeds are used for food and for making gluten-free products.

Tips for growing, harvesting and storing:

Cultivation:

  • Soil and Lighting: Sorghum grows in a wide range of soils, but produces best results in well-drained, fertile soils with a pH of 6 to 7,5. Sorghum prefers sunny locations and can grow throughout the season in strong light conditions.
  • Planting and Depth: Sorghum seeds are best sown into the soil immediately after it has warmed up to 18-20°C. The sowing depth should be about 2,5-3 cm.
  • Distance between plants: The distance between plants depends on the purpose of cultivation. For a high grain yield, sorghum plants should be planted at a distance of 30-45 cm from each other, and for the production of animal feed, plants can be planted closer to each other.
  • Plant care: In the first weeks after planting, keep an eye on the soil and keep it moist. Sorghum does not need to be watered often, but if the soil becomes dry, it should be watered. Remove weeds and apply nitrogen fertilizer early in the growing season.

Preparation and storage:

  • Sorghum seeds can be used as livestock feed or to make flour and syrup.
  • To preserve the seeds, they must be stored in a dry, cool place to avoid breaking or spoiling.

Sorghum seeds can be used as a substitute for rice or other grains in food recipes. A syrup made from sorghum can be used as a sweet addition to meals or drinks. The starch produced from sorghum can be used as a thickener for soups and sauces.

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

The car will not hit a pedestrian 02.11.2014

Automaker Honda Motor has announced a new active safety system, with which the car will be able to independently avoid collisions with pedestrians and other vehicles. The technology, called Sensing, will first appear in the new version of the Legend business sedan, and will later be available in other models of the Japanese brand.

The presented electronic assistant uses a special radar installed in the radiator grille and serves to recognize pedestrians. Their height can be determined by a camera placed at the top of the windshield.

The system, analyzing the situation in front of the car at a distance of up to 60 meters, can calculate the likelihood of a collision with people walking nearby. The electronics will warn the driver about the danger with a sound and visual signal on the dashboard, and if necessary, slow down the car, stop it completely or make a safe maneuver.

According to the developers, Sensing is able to predict the actions of other road users. In addition, when driving in a traffic jam, the technology will tell the person behind the wheel about an attempt to over-accelerate (the accelerator pedal will vibrate) and notify the need to start moving when the flow has started.

Finally, Sensing has the capabilities of adaptive cruise control, lane keeping systems and traffic sign recognition.

Honda will add Sensing to the facelifted Legend, which will hit the Japanese market in late 2014. Then other cars of the manufacturer will be equipped with the system.
