Productivity and quality of some annual forage legumes as influenced by different growth stages and cutting treatments in rainfed areas
1992
Ayad, J.Y.M.
Two defoliation trials were conducted at M'shagar location (Jordan), to evaluate the effect of growth stages and cutting height treatments on forage yield and quality of seven annual forage legumes species, namely: wooly pod vetch (Vicia dasycarpa), common vetch (Vicia sativa), bitter vetch (Vicia ervilia), narbon vetch (Vicia narbonensis); ochrus chickling (Lathyrus ochrus), dwarf chickling (Lathyrus cicera) and common chickling (Lathyrus sativus). In the growth stages trial, forage yield was increased significantly as plants advanced in growth from 10% flowering to full podding time. Narbon vetch produced the highest dry forage yield in 1989/90 season, while common vetch ranked the highest in 1990/91 season. For all genotypes, as plant growth advanced to full pod formation, digestibility, crude protein, ash content and leaves to branches ratio were decreased while crude fiber content was increased. Bitter and common vetch had the higher digestibility levels at the first and second seasons, respectively, while dwarf chickling, common chickling and wooly pod vetch had the highest crude protein content over the two seasons. Concerning cutting heights trail, generally, 10 cm cutting gave better regrowth and produced higher seasonal forage yield, digestible dry matter yield, crude protein yield and ash yield. Over the two seasons, common vetch, dwarf chickling, common chickling had the highest seasonal forage yield under different cutting height treatments
