THE EFFECT OF THE FRACTIONAL COMPOSITION OF CEREALS AND SOWING PERIODS ON THE GERMINATION OF AUTUMN WHEAT GRAIN AND THE NUMBER OF COBS

This article provides information on the germination of autumn wheat varieties and sowing dates for the number of productive cobs, as well as the effect of grain fractionation. As an object of research, autumn soft wheat varieties were obtained. The studies were carried out in the conditions of moderately saline hungry salt porridge soil. Special sieves with grain diameter <2mm; 2 - 2.5 mm; 2.5-3mm and 3.0<mm are separated into fractions in aid. In the large fraction, the yield of grain in field wine was 60.91%, the number of spikes was 580.7, in the middle fraction, respectively: 54.51%; 471.96; in the light fraction, 48.99%; 381.23. When planted in September, the yield was 63.72% for productive cobs at 572.76, in October respectively; -53.77%; 494.43; and in November -46.9% at 366.73. Autumn wheat varieties have been found to have a 6.87% yield compared to October when planted in November and a 127.7 spike count , a 16.82% decrease compared to September and a 206.0 decrease in the number of spikes. Medium to large fractional grain was recommended for planting.
