YIELD AND SOWING QUALITIES OF SPRING WHEAT DEPENDING ON VARIETY AND FOLIAR TREATMENT WITH MANGANESE, COPPER AND MOLYBDENUM
The article presents data on grain yield and sowing qualities of the resulting spring wheat yield, depending on the variety and the use of microfertilizers of manganese, copper, molybdenum and "Ultramag combi". The research was carried out in a two-factor short-term field experiment carried out in 2018-2019 in Mordovian Research Institute of Agricultural Research, a branch of the North-East Federal State Budgetary Scientific Research Center under heavy loam leached chernozem condition. The experiment scheme included 21 variants: factor A: spring wheat variety: 1) Tulaykovskaya 10 (standard); 2) Tulaykovskaya 108; 3) Yoldyz; Factor B: foliar treatment with fertilizers: 1) control (tap water treatment); 2) N in amide form (background): 0.39 kg/ha 3) background + Mn+Cu; 4) background + Mn+Mo; 5) background + Cu+Mo; 6) background+Mn+Cu+Mo; 7) « Ultramag combi» - 2 l/ha. Mixtures of trace elements Mn, Cu, Mo were used in a total concentration of 0.03 %, equivalent to the total concentration of trace elements in the working solution of preparation "Ultramag Combi". The treatments were carried out twice in the tillering and earing phase. It was found that the best productivity indicators were formed in spring wheat of the Yoldyz variety. The highest yield of spring wheat of the Tulaykovskaya 10 and Tulaykovskaya 108 varieties was formed during foliar treatment of crops with a paired mixture of copper and molybdenum on the background of nitrogen, and the Yoldyz variety - manganese and copper, as well as manganese and molybdenum on the background of nitrogen. The Yoldyz variety had the greatest responsiveness in improving the sowing qualities under the influence of fertilizer preparations. Paired application of manganese and copper, manganese and molybdenum, as well as the preparation "Ultramag combi" was the most effective of the studied combinations of microfertilizers, in improving the complex of sowing qualities of spring wheat varieties Tulaykovskaya 10 and Yoldyz.
