INFLUENCE OF SOWING DATES AND RATES ON THE YIELD AND OIL CONTENT OF SUNFLOWER VARIETIES
Keywords:
Sunflower, variety, term, rate, oil quantity, yield, ton, centner, percent.Abstract
The article established that the yield and seed oil yield of sunflower varieties were higher in the Buzuluk variety when sown on April 15th and with a seeding rate of 60,000 seeds/ha compared to the Dilbar and Zarrin varieties. The yield of the Buzuluk variety was 38.3 c/ha, seed oil yield was 48.7%, and 1.9 tons of oil were obtained per hectare. The control Dilbar and the Zarrin varieties yielded high and oil yield was high during these periods and variants. It has been proven that sowing sunflower varieties on April 1 and May 1 can reduce yield and oil yield, and it has been established that increasing the sowing rate has a negative impact.
