| Popis: | Buckwheat is a very valuable food crop, widely in demand not only in Russia, but also in the world agri-food market. Buckwheat belongs to pseudo-grain culture and is therefore of particular interest for crop rotation diversification and is suitable for organic farming. Scientists have long faced the question about the reasons for obtaining low yields of buckwheat grain with the high biological yield potential. We can talk about two groups of reasons that reduce crop productivity: the first are agrotechnical, the second are biological. Agronomic reasons are sowing buckwheat after bad and clogged previous crops, often after spring plowing, insufficient weed control before sowing, insufficient mineral nutrition, untimely sowing, poor plant care, lack of pollinators, large losses of grain during harvesting. The biological causes include dimorphism of flowers. The purpose of this work is to determine the influence of growth stimulant, fertilizer and previous crops on the buckwheat yield in Siberia. The role of adding ammonium nitrate and the use of the growth stimulant «Zerebra Agro» in the productivity formation of this crop was studied, as well as the influence of previous crops on its yield value. Six varieties of buckwheat were used as the object of research. Analysis of influence indicators in our studies revealed that buckwheat yield depends by 19% on its previous crops, by 12% on the means of intensification, by 29% on the interaction between the previous crops and means of intensification and by 39 % on unaccounted factors. |
