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

This study was conducted on some fodder pea [Pisum sativum ssp.] in Mardin ecological conditions. arvense (L.) Poir.] varieties to determine herbage yield and quality characteristics. Research; It was carried out in the 2022-2023 growing season on the farmer's land in Akıncı District of Artuklu district of Mardin province. In the research, Özkaynak, Taşkent, Gölyazı, Töre, Hat-1, Assas, Ateş, Arda, Kurtbey, Kirazlı, Ulubatlı, Ürünlü, GAP Pembesi and Livioletta feed pea varieties were used as plant material. In the research, the field experiment was set up according to the randomized block trial design with 3 replications. In the study; natural plant height, herbage yield, hay yield, crude protein rate, acid detergent fiber, neutral detergent fiber, digestible dry matter, relative feed value. Agricultural characteristics such as were examined. As a result of the research, statistically significant differences at the P≤0,01 level were detected among the varieties in terms of all examined characteristics. In the research, according to varieties; plant height 62,07-94,27 cm, herbage yield 1583,33-4266,67 kg/da, hay yield 425,67-1125,00 kg/da, acid detergent fiber 21,20-32,89%, neutral detergent fiber 35,08-44,92%, crude protein rate 17,27-22,31%, digestible dry matter ratio 63,28-72,39%, dry matter intake 2,68-3,42% and relative feed value 131,43-184,09. According to the one-year results obtained from the research; in the climate and soil conditions of Mardin province, the cultivation of fodder pea as a winter intercrop showed differences in terms of quality, and in terms of grass yield, the use of GAP Pembesi and Ulubatlı varieties can be recommended.
