Influence of fertilizers on crop yield of modern buckwheat varieties of various morphotypes

详细

In 2012–2014, the crop yield and response to presowing application of mineral fertilizers (NPK)₄₅ of 19 buckwheat varieties of various morphotypes were studied. The crop yield of the Bogatyr standard variety at natural fertility and application of fertilizers was statistically surpassed by such determinant varieties as Dozhdik, Devyatka, Dikul, Dialog, Design (the grain harvest increment was 0.30–0.42 t/ha) and Dozhdik, Devyatka, Dikul, Dialog, Design, Temp (by 0.40–0.63 t/ha). The Temp and Dialog short-stalk varieties showed the best response to application of mineral fertilizers: their productivity increased by 15%.
