Abstract

The grain and straw productivity and transpiration coefficients of spring wheat of the Tulaykovskaya 10 cultivar were studied depending on the conditions of moistening and foliar treatment with manganese, zinc, and cobalt. The main research method was a two-factor vegetation experiment in triplicate. Earlier, the interaction of minor nutrient elements - manganese, zinc and cobalt - against the background of drought and sufficient moisture in spring wheat crops has not been studied on the leached chernozems of Mordovia. It was revealed that against the background of sufficient moisture in the soil, the yield of spring wheat increased with foliar treatment with a combination of manganese and zinc, and against a background of drought - with a combination of manganese, zinc, and cobalt. Soil drought significantly increased the transpiration coefficient. Over 2 years of research, a decrease in the transpiration coefficient against the background of sufficient moisture was caused by the paired use of manganese and zinc, and against a background of drought - by manganese and cobalt, and by triple use of manganese, zinc, and cobalt.
