INFLUENCE OF SOWING DATES AND NORMS ON THE SEEDLING THICKNESS SOYBEAN VARIETIES

Abstract

This article presents data on the effect of different planting dates and rates on the seedling density of soybean varieties "Madad" and "Sevinch" and their analysis. When soybean varieties were planted 10 days later than the early planting date (25.04-30.04), the number of plants that died was from 0.8% to 1.9%, and when planted 20 days later, the number of plants that died was from 2.0% to 3.0%. When the planting rate was increased by 15 kg per hectare compared to 45 kg per hectare (60 kg), the number of seedlings that died was from 1.8% to 2.9%, and when increased by 30 kg per hectare (75 kg), the number of plants that died was from 2.3% to 5.5%.
