Sunflower yield at different sowing terms in the conditions of the Non-Black Earth Zone of Russia
The authors have considered the possibility of cultivating new varieties and hybrids on the gray forest soils of the Non-chernozem zone of Russia. The influence of two sowing dates was studied: 1 decade of May (1-5 May), 3 decade of May (20-25 May). Studies have shown that the sunflower of the first term of sowing gave a higher yield in Samantha, Ozaro hybrids, variety Poseidon-625. At the same time, the hybrid Walzer sowing time in the experiments did not have a significant impact on yield, and amounted to 28-28.3 q / ha. Later sowing time contributed to obtaining higher yields in hybrids Nova (23.9 centners per hectare), Larisa (26.4 centners per hectare). Keywords: SUNFLOWER, RYAZAN REGION, CROPS TREATMENT, YIELD
