Effects of Rate of Mixture and Time of Harvest on the Winter Second Crop Performances of Mixtures of Some Annual Legumes and Italian Ryegrass

23154

This study was conducted in order to determine the effects of different harvest dates (Early Spring; the last week of March, Mid Spring; second week of April and Late Spring; last week of April) and various mixture rates (mixture of italian ryegrass + legume; 100+0%, 80+20%, 60+40%, 40+60%, 20+80% and 0+100%, respectively) of some annual legumes (Vicia sativa, Lathyrus sativus and Pisum arvense) with Italian ryegrass on the herbage yield and other yield characteristics. The field trials were carried out at Bornova Experimental Station, Ege University Faculty of Agriculture during the years of 2012-2014. As the average of 2-year results, it was determined that the highest yields were obtained from İtalian ryegrass + legume mixtures sown as winter second crop and harvested in late spring under Mediterrenean climatic conditions. However, the data also indicated that pure common vetch sowing provided the highest green matter, dry matter and crude protein yields, being 5378 kg/da, 1148 kg/da and 230 kg/da, respectively. Legume ratio, NDF and ADF rates increased by advancing harvest dates
