The Effect of Different Organic Fertilizer Applications on Yield Components of Some Rapeseed (Brassica napus L.) Varieties

Abstract

This research was carried out in Dicle University, Agriculture Faculty research and application area in the 2019-2020 growing season to determine yield and yield components by using different organic fertilizer applications and chemical fertilizers on different rapeseed varieties. In the research, 2 rapeseed varieties (Exstorm, Es Hydromel) were placed on the main plots and 6 fertilizers (solid cattle manure, liquid cattle manure, sheep manure, worm manure, chicken manure) were placed on the sub-plots and used as material. The experiment was carried out according to the randomized blocks divided plot design with 4 replications. In the research; plant height, number of branches, first capsule height, number of capsules, number of seeds in the capsule, capsule length, capsule width, thousand-seed weight, seed yield, oil ratio and oil yield properties were investigated. Seed yield in the investigations; It varies between 175.43-247.15 kg da^-1 in rapeseed varieties and 144.78-353.31 kg da^-1 in fertilizers. It varies between 43.23% and 45.35% in varieties and between 43.05 % and 46.02 % in fertilizers, oil yield; It was determined that it varies between 75.19-112.11 kg da^-1 in cultivars and between 64.61 and 154.03 kg da^-1 in fertilizer applications. The highest grain and oil yield values were obtained from Exstorm variety, and chemical fertilizer application in fertilizer applications. It was observed that the chemical fertilizer application was followed by the chicken manure application.
