Determination of Grain Yield and Some Forage Quality Traits of Rye Genotypes at Different Sowing Densities

Abstract

The objective of this study was to determine grain yield and forage quality of rye genotypes under the impact of different sowing densities (350, 425, 500, 575, 650, 725 seeds m(-2)). The study was conducted in 2014-2015 and 2015-2016 growing seasons using four genotypes, one registered triticale (Karma-2000) and one rye (Aslim-95) and two local ryes (Bayburt and Yozgat). The experiments were performed in a split-plot design with three replications, genotypes took place at main plots and sowing densities at sub-plots. According to the results of the variance analysis of the combined years, genotypes and sowing densities (except oil ratio) were found to be statistically significant in terms of grain yield, plant height, thousand grain weight, starch content, crude protein content, crude fat content, acid detergent fiber (ADF) and neutral detergent fiber (NDF) values. While the highest grain yield was obtained from 575 sowing density per m(2) with 3.94 tons of ha(-1), the optimum sowing density was determined as 563 seeds/m(2) according to the regression equation. When we evaluated the rye genotypes within themselves, it was concluded that the local genotypes had better values than the Aslim-95 cultivar in terms of quality traits.
