Changes in Yield, Quality and Nutrient Content of Forage Rape (Brassica napus L. ssp. oleifera Metzg) in Different Sowing Times

This study was conducted in the ecological conditions of Bingol province from 2014 to 2016 to reveal the differences of yield, quality and nutrient content of forage rape based on different sowing times. Starting from the second half of September, the study was sown at 4 planting times with 10-day intervals. It was determined that the highest values were obtained from the second half of September in terms of forage yield and dry matter yield from the yield characteristics, NDF and RFV from the quality characteristics and Ca and Mg from the nutrients. It was observed that the sowing times in forage rape did not show any statistically difference in terms of CP, ADF, DDM, P and K. Therefore, it was concluded that it would be advantageous in terms of yield and quality to cultivate forage rape in the second half of September in terrestrial regions such Bingol or areas with the similar ecological conditions.
