Effect of different phosphorus dose applications on yield and some yield components of Bitter vetch (Vicia ervilia L.)

This research was carried out in Konya ecological conditions in 2019 in order to determine the effects of 5 different phosphorus doses (0, 4, 8, 12 and 16 kg / da) on yield of vetch (Vicia ervilia L.). The experiment was set up in 3 repetitions according to the random blocks trial pattern. In the study, plant height, pod length, pod width, number of pods in the plant, grain number in the plant, thousand grain weight and grain yield were investigated. The effect of phosphorus doses on plant height, number of pods, thousand grain weight and grain yield was found statistically significant at the level of 5%. According to the phosphor doses applied in the vetch, plant length is 24.2-28.3 cm, pod length is 16.1-18.1 mm, pod width is 4.23-4.60 mm, pod number is 17.3-28.8, pellet number is 38.7-63.07, thousand grain weight is 31.3-36.6 g and grain yield varied between 48.1-86.7 kg/da. While the highest grain yield was obtained in 12 kg/da and 16 kg/da phosphorus application, the lowest values in all parameters were obtained from control plots that no phosphorus application was made.
