The effect of growth stimulants of plant on photosynthetic activities of soybeans crop

«OIL CROPS» Scientific bulletin, VNIIMK, 2006, is 2 (135). The effect of new growth stimulants of plant on photosynthetic activities of soya beans crop and it's relationship with seed productivity was studied. Field experiments have shown that, the highest productivity of soya bean's variety Vilana is observed under the influence of growth stimulants - albit and bishofit which is explained by the high indicators of photosynthetic potential during the vegetative period. All the studied growth stimulants also considerably increased the photosynthetic productivity and accumulation dry matter.
