Influence of sowing dates and norms on harvest of lentils varieties

In this article, it is given about data on influences of sowing dates and norms on harvest of lintels varieties. When sowing of lentils varieties in norm of 2 million per hectare in the autumn, the grain yield of “Oltin don” was found that at the time of sowing of seeds 15,6- 17,3 c / ha, and "Darmon" variety - 24,1-26,1 / ha. When the highest grain yield in both varieties is 3 million pieces per hectare was taken, and increase of sowing rate from 2 million / ha to 3 million / ha, it is found that productivity was increased to 2.7-3.1 c / ha. However, an increase in the planting rate by 4 million units per hectare resulted in a decrease in yield by 1.1 c / ha. An analysis of the yield of sorts of lentils in the spring period revealed that, if with the increase in planting rates, the grain yield of the "Oltin don " increased from 15.1 cent to 17.8 cent. Vice versa, in variant of increasing planting norms to 4 million pieces, it was found an decrease of harvest.
