The effect of mixture rates and cutting stages on some yield and quality characters of pea (pisum sativum L.) plus oat (avena saliva L.) mixture

This research was conducted to determine the effects of seed rates in mixtures of pea+oat and cutting stages on the hay yield and its quality. The experiment was performed over two years (2003-2005) at Uludag University, Faculty of Agriculture, Agricultural Research and Application Center, Bursa, using five different mixture rates of pea and oat crops (100% Pea+0% Oat, 75% Pea+25% Oat, 50% Pea+50% Oat, 25% Pea+75% Oat and 0% Pea+100% Oat) and three different cutting stages (the jointing stage of oat, the stage oat in scabbard and milk-dough stage of oat). According to the results, it may be suggested that the mixture of 25% pea+75% oat should be grown to obtain higher hay yield and the mixture of 50% pea+50% oat to obtain higher level of crude protein. In addition, the pea+oat mixture should be harvested at oat milk-dough stage
