Scientists are revising wheat cultivation technologies to increase yields

MOSCOW, April 7 – RIA Novosti. The first comprehensive study of new perennial crops in Russia will be carried out by scientists from the Don State Technical University (DSTU) and the Agrarian Scientific Center “Donskoy” (ANC “Donskoy”). According to the researchers, the revision of the cultivation technology will help to increase the yield of perennial wheat and feed raw materials from ears, as well as improve their quality. This was reported by the press service of the university.

According to experts, back in 1928, the famous Soviet breeder Nikolai Tsitsin began a great research work, as a result of which he made an outstanding contribution to world science: he first got a hybrid by crossing wheat with wheatgrass. This marked the beginning of scientific work on the creation of mixed crops, which retain the best properties of both plants and are biologically more valuable and, which is especially important, perennial.

A team of scientists from DSTU and ANC “Donskoy” will conduct the first in Russia comprehensive study of the newest perennial crops: drought-resistant wheat “Trititrigia tsitsini”, named after Tsitsin, and the selected gray wheatgrass variety “Sova”. After the ear has ripened, new shoots grow especially quickly in such crops. This allows, after harvesting the grain, to receive up to three mows of green mass – a very valuable feed raw material.

“Based on the results, we will propose a technology suitable for the south of Russia for a full cycle of growing perennial grain crops and create high-value feed additives, taking into account the individual needs of animals, birds and fish. In addition, we plan to substantiate the effectiveness of a new harvesting method using resonant frequencies.” – commented the dean of the faculty “Agroindustrial” DSTU Dmitry Rudoy.

According to DSTU specialists, at present there are no scientifically substantiated harvesting technologies that would make it possible to efficiently harvest, separate and process the grain and green parts of the crop, as well as maximize the use and processing of ears.

“Wheat is now harvested at full ripeness. There are many scientific studies that show that gluten, protein and amino acids are reduced during the ripening process. In addition, with the traditional method of harvesting, direct combining, it is technically possible to harvest these crops directly at an early stage. stages of ripeness is impossible “, – said Tatyana Maltseva, junior researcher of the research laboratory” Center of Agrobiotechnology “DSTU.

Agronomists are going to sow perennial crops in different ways and technologies. They will study their biological feeding properties at different stages of ripening – from milk to full ripeness, as well as assess the amino acid composition, the content of minerals and the physical and mechanical properties of the plant mass. Experts plan to justify the harvesting method in the early stages of ripeness.

One of the research stages will be the analysis of harvesting technologies. The research team plans to harvest the grain by stripping using the resonant frequencies (vibrations) that occur when the harvester moves. This method allows you to harvest mainly grain, while it is less injured. The stalk remains unmown in the field, and new green shoots will grow on it.

“A conventional harvester cannot collect such wheat, it will grind it into a single mass. Together at the Donskoy Research Center, we have developed new equipment, and with scientists from the Russian Academy of Sciences, we have determined the frequencies at which the grain better leaves the ear. The first tests have already passed.” noted the dean of the faculty “Agroindustrial” DSTU Dmitry Rudoy. Ученые пересматривают технологии выращивания пшеницы для повышения урожая

Experts believe that new technologies will reduce the cost of planting and harvesting by 15 percent. This will be possible with the help of new combines and reduction of agricultural time due to harvesting grain at an early stage of ripeness. The new technique will allow harvesting with less losses, since at the moment the harvesters do not have time to harvest full-ripe wheat, experts said.

Seeds of perennial crops for research will be provided by the Omsk State Agrarian University named after P.A. Stolypin.
