THE EFFECT OF MIXTURE RATES AND CUTTING STAGES ON SOME YIELD AND QUALITY CHARACTERS OF PEA (Pisum sativum L.)+OAT (Avena sativa L.) MIXTURE

Abstract

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[1]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.
