Determination of yield and quality characters of some grasspea (Lathyrus sativus L.) genotypes in different plantdensity

This study was conducted to determine the hay yield, quality and seed yield, quality of some grasspea (Lathyrus sativus L.) genotypes (Gap mavisi, Karadağ, Popülation) grown at four different plant densities (75, 100, 125, 150 seed/m 2 ) in Bursa ecological conditions. This experiment was carried out at Bursa Uludag University, Faculty of Agriculture Agricultural Research and Application Center in Bursa in the 2017-2018 growth period and the experiment was established according to the randomized complete block design with three replications. The number of branches, the number of tillers, the stem thickness, forage yield, dry matter rate, dry matter yield, crude protein rate and yield in grass, ADF and NDF rates for forage, plant height, seed number in the pod, seed number in the plant, pod number in the plant, seed yield, 1000 seed weight, biological yield. harvest index, crude protein rate and yield for seed were determined in this study. In the genotype x plant density interactions; the highest forage yield was obtained from the Karadağ and Popülation at 100 seed/ m 2 plant density, the highest dry matter yield was produced by Karadağ at 100 seed/m 2 plant density, the Popülation had the highest forage crude protein rate at 100 seed/m 2 plant density, the forage crude protein yield of the Popülation and Karadağ genotypes was higher than the other genotypes at 100 seed/m 2 plant density, the highest 1000 seed weight was determined from the Popülation at 75 and 100 seed/m 2 plant densities. The Karadağ cultivar had the highest seed yield and the highest seed yield wad obtained 75 seed/m 2 plant density. According to the one-year this research, in order to obtain higher yield and quality hay, Karadağ cultivar could be grown at 100 seed/m 2 plant density. In order to obtain higher seed yield and seed quality, Karadağ cultivar could be grown at 75 seed/m 2 plant density in Bursa ecological conditions.
