Abstract
Bu araştırmada, Bursa koşullarında kışlık ara ürün olarak ot üretimi ve yeşil gübreleme amacıyla yetiştirilen adi fiğin, farklı azot dozları uygulanarak yetiştirilen mısır bitkisinde tane verimi ve bazı tarımsal özellikler üzerine etkisi incelenmiştir. Deneme, 1999-2002 yıllarında Bursa koşullarında üç yıllık olarak yapılmıştır. Buğday anızının kontrol olarak kullanıldığı çalışmada mısırda 0, 7.5, 15.0, 22.5, 30.0 ve 37.5 kg N/da dozları ele alınmıştır. Mısır bitkisinde ot üretimi amacıyla yetiştirilen adi fiği izleyen mısırdan 1470.2 kg/da değeri ile en yüksek tane verimi elde edilmiştir. Ot üretimi uygulamasını 1391.7 kg/da ve 1391.5 kg/da değerleri ile buğday anızı ve yeşil gübreleme takip etmiştir. Ot üretimi parsellerinde elde edilen tane verimi yeşil gübrelemede elde edilen verimden % 5.66, buğday anızından elde edilenden % 5.64 daha yüksek bulunmuştur. Azot dozu arttıkça tane verimi de düzgün bir artış göstermiş ve en yüksek değerine 30 kg N/da dozunda ulaşmış, ondan sonra düşüşe geçmiştir.
In this research, the effect of common vetch used for green manure and forage production as a winter catch crop on seed yield and some agronomical traits of corn which were grown on different nitrogen doses was investigated. First factor was previous crop treatment (common vetch as green manuring and forage production, and wheat stubble). Field experiments were conducted on corn during three years (1999-2002) in Bursa. Wheat stubble was used as control in previous crop treatment. As second treatment, nitrogen doses; 0, 75, 150, 225, 300 and 375 kg N ha-1 for corn were tested in this study. In the corn experiments, the highest seed yield (14702 kg ha-1) was obtained from corn subsequent to common vetch for forage production followed by previous crop treatment; wheat stubble (13917 kg ha-1) and green manuring (13915 kg ha-1). Corn subsequent to common vetch grown for forage production gave higher yield 5.66 % and 5.64 % than green manuring and wheat stubble, respectively, seed yield of corn increased when nitrogen doses were increased and the highest yield was attained in 300 kg N ha-1 seed yield decreased in higher nitrogen doses.
