INFLUENCE OF FOLIAR FERTILIZATION OF WINTER WHEAT WITH WATER SOLUBLE COMPOUND FERTILIZER WITH MICROELEMENTS "POLY-FEED" FOR YIELD AND QUALITY GRAIN IN THE CONDITIONS OF THE ORYOL REGION
Often in the soils of crop rotations of grain crops, including on black soil, the content of mobile forms of copper, manganese, zinc and other trace elements is low. Improving the efficiency of making micronutrients for grain crops and determining the best ways and doses of their introduction are topical issues that need to be addressed in order to increase the productivity of crops. The purpose of research is to identify the effectiveness of the use of water soluble compound fertilizer with
... fertilizer with microelements of the company "Haifa Chemicals" in the technology of growing winter wheat on leached chernozem under conditions of the Oryol Region. Field production experiments were established in 2017-2018 on the basis of Orlovsky Leader LLC Branch №5" located in Livensky district. Field experience with the use of Haifa Chemicals products: Poly-Feed micronutrients 19-19-19 + 1MgO + ME and Poly-Feed 6-15-38 + 3 + ME was laid on soft winter wheat varieties Moskovskaya-56.The control variant was the basic technological scheme used in the household for carrying out leaf dressings with mineral fertilizers together with the organic fertilizer Gumostim. As a result of the research, it has been established that the use of double foliar feeding water soluble compound fertilizer with microelements Poly-Feed 19-19-19 + 1MgO + ME in the tillering stage and at the end of flowering and a single Poly-Feed 6-15-38 + 3 + IU in the subflag phase - flag leaf, increases the height of the plants, as well as the productive characteristics of the ear: the size of the ear, the number of grains in the ear, the mass of grains and their best quality, which in general provides a reliable increase in the yield of grain of winter wheat. At the same time, it was found that, due to leaf feeding, the impact of adverse weather conditions under which the development of winter wheat plants took place in 2018 and their productive properties were laid was leveled out. Due to relatively low additional costs, the use of complex fertilizers of the Poly-Feed brand for winter wheat is economically feasible and can bring additional economic income: based on the maximum level of minimum prices for the grain of the 2018 harvest, it will be 2.07-2.28 thousand rubles / ha regarding base technology. Thus, water-soluble fertilizers, which include Poly-Feed company "Haifa Chemicals" are recommended to domestic agricultural producers for mass introduction in practice of the technology of intensive sheet nutrition of grain and other crops.
