The influence of various elements of technology of cultivation on the productivity of buckwheat

Buckwheat is a very valuable food crop, widely demanded not only in the Russian, but also in the world agrofood market. Buckwheat belongs to pseudo-grain crops and therefore is of particular interest for diversifying crop rotations and is suitable for organic farming. The question of the reasons for obtaining low yields of buckwheat grain with a high biological potential of productivity has long been studied by the scientists. There are two groups of reasons reducing crop yield: the first is agrotechnical, the second is biological. Agrotechnical reasons include sowing buckwheat after poor and littered predecessors, often by spring plowing, insufficient weed control before sowing, insufficient mineral nutrition, untimely sowing, poor plant care, the lack of pollinators, grain crumbling, large grain losses during harvesting. Biological reasons include flower dimorphism. The aim of the work is to determine the effect of growth stimulator, fertilizer and predecessors on the yield of buckwheat in Siberia. The role of the introduction of ammonium nitrate and the use of the growth stimulator Zerebra agro in the formation of the productivity of this crop, and also the influence of predecessors on the size of its yield were studied. Six varieties of buckwheat were used as the object of the study: Dikul, Dasha, Zemlyachka, Temp, Zarina, Druzhina. The analysis of the power of the influence indicators in the studies revealed that buckwheat yield depended by 19 % on the predecessor, by 12 % on the means of intensification, by 29 % on the interaction of the predecessor and means of intensification, and by 39 % on unaccounted factors.
