Soybean productivity at foliar application of microfertilizers and growth stimulants on leached chernozem

Micro- and complex mineral fertilizers, plant growth stimulants applying at the beginning of variety Delta flowering were studied. They positively influenced on grain yield, protein content, oil and protein yield and did not increase oil content in seeds. The usage of chelate mixtures Zn, Cu, Co, Mn with boric acid and МоО2(C5Н7О2)2 as well as plant growth stimulants Emistim С and Silk have influenced maximally effectively on these components. Application of fertilizers and plant growth stimulants increases yield on 0.17-0.32 t/ha (7.6-14.3 %), protein content in seeds on 1.5-2.1 %, protein yield on 78-160 kg/ha (9.9-20.3 %), total yield of protein and oil on 100-204 kg/ha (8.3-16.8 %) and decreases oil content in seeds on 0.3-0.8 %. 158
