Selection as one of the ways of agriculture for increasing yield

In modern agronomy, the variety acts as an independent factor in increasing the yield of any agricultural crop and along with agricultural technology, is of great, and in some cases crucial, importance for obtaining high and stable yields.The purpose of the research was to use a separate direction of the agrotechnical method, in which the variety acts as an independent factor in increasing yields. On average, over three years, the best varieties exceeded the standard variety Don 95 in yield by 0.20 kg/m2 Donskoy Mayak and 1393/04 (line), Donschina by 0.19 kg/m2, Znakhidka Odesskaya has an increase in yield from the standard variety Don 95 0.18 kg/m2, Zernogradka 10 and Perlina 0.16 kg/m2, Samanta and SERI 0.12 kg/m2. The yield Of these varieties on average for three years of research is: Donskoy Mayak - 0.80 kg/m2, 1393/04 (line) - 0.80 kg/m2, Donschina and Znakhidka Odesskaya - 0.78 kg/m2, Zernogradka 10 - 0.76 Kg/m2, Perlina - 0.75 kg/M2, Seri - 0.72 kg/m2 and Samanta - 0.71 kg/m2.
