Özet
The effects of previous crops (wheat, barley, lentil, Hungarian vetch and fallow) and different nitrogen rate (0, 120, 160, 200 and 240 kg N ha(-1)) on grain yield and yield components of maize (Zea mays L.) were evaluated under irrigated conditions in Diyarbakir, Turkey in the 1999-2000, 2000-2001 growing seasons. Maize was grown in summers and wheat, barley, lentil and Hungarian vetch in winters. In-the study, grain yield of maize varied between 6340.3 and 11598.9 kg ha(-1). It was determined that Hungarian vetch was suitable for previous crop and 160 kg ha(-1) N rate is the best nitrogen rate in maize production. According to the interaction of previous crop-nitrogen rate, the highest yield was obtained from the subject grown after lentil and Hungarian vetch with 160 kg N ha(-1). Maize following legumes in rotation did not respond to applications over 160 kg N ha(-1), while barley-maize, wheat-maize increased at all levels of N applied. Fallow-sorghum did not respond to-application over 200 kg N ha(-1).
