Determination of yield and yield components of some forage pea [Pisum sativum ssp. arvense (L.) Poir.] cultivars in Siirt ecological condotions

This study was carried out to determine forage yield and quality characteristics of some forage pea [Pisum sativum ssp. arvense (L.) Poir.] cultivars in Siirt ecological conditions. The research was conducted during 2018-2019 growing seasons in Siirt University, Agricultural Faculty, Research and Application Land. In research was used as material Özkaynak, Taşkent, Gölyazı, Kirazlı, Ulubatlı, Ürünlü, GAP Pembesi and Livioletta forage pea cultivars. In the research field experiment was set up randomized complete block experimental design with three replicates. The study was investigated agricultural properties such as flowering period, natural plant height, stem number, main stem thickness, herbage yield, hay yield, crude protein (CP) ratio, acid detergent fiber (ADF), neutral detergent fiber (NDF), CP yield and relative feed value (RFV). In terms of all the characteristics examined in the research, statistically significant differences were determined p<0.01 among the cultivars. According to the result flowering period, natural plant height, stem number, main stem thickness, herbage yield, hay yield, CP ratio, ADF ratio, NDF ratio, CP yield and RFV were changed between 155.0-177.7 day, 52.3-101.4 cm, 1.9-3.5 number/plant, 3.50-5.93 mm, 1441.0-5013.3 kg/da, 291.1-925.4 kg/da, 12.68-19.47%, 32.53-37.20%, 44.63-48.93%, 37.33-179.93 kg/da and 116.2-132.6 respectively. According to the one year results obtained from the research; It may be suggested that Özkaynak cultivar should be used for the production of herbage and hay in forage pea cultivation as a winter intermediate product in Siirt province climate and soil conditions.
