Determination of Forage Yield Performance and the Possibilities at Entering Crop Rotation System for Some Annual Forage Legumes Species in Ecological Conditions of Çinar District

13354

The study was carried out to determine forage yield performance and it effecting traits and possibilities at entering crop rotation system for some annual forage legume species in ecological conditions of Cinar district, Diyarbakir, Turkey. For this reason; the experiments were performed during 2008-09 and 2009- 10 growing seasons according to a complete randomized blocks design with three replications. The cultivars used in the study as a material were from different eight annual forage legume species, common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica CRANTZ.), forage pea (Pisum sativum spp. arvense L.), narbon vetch (Vicia narbonensis L.), grass pea (Lathyrus sativus L.), bitter vetch (Vicia ervilla (L.) Willd), hairy vetch (Vicia villosa ROTH.) and black chickpea (Cicer arietinum L.). According to the averages of combined the two years; days to 50% flowering, fresh forage yield, dry matter yield, natural plant height, main stem height, number of main stem per plant and the main stem thickness varied between the species respectively; 152.5-165.2 days, 1257-2483 kg da-1, 390.3-663.7 kg da-1, 32.47-74.00 cm, 41.35-93.95 cm, 1.57- 4.17 number plant-1, 1.66-3.35 mm. As a result of the research; it was concluded that forage pea (Pisum sativum spp. arvense L.), hairy vetch (Vicia villosa ROTH.) and grass pea (Lathyrus sativus L.), were found the most yielding species in terms of forage yield respectively, and forage pea (Pisum sativum spp. arvense L.), and bitter vetch (Vicia ervilla (L.) Willd), were found the earliest flowering species. Moreover; taking into consideration the forage harvest time of the species, all of the species have opportunity to enter crop rotation system, with cultivation of cotton (Gossypium hirsutum L.) and corn (Zea mays L.), the most cultivating crops in the region as a cottage plants, on conditions that the forage species are sown in the autumn and in order to obtain forage yield or for green manure purposes
