Abstract
15N metodu kullanarak, Orta Anadolu kuru koşulları altında kışlık ve yazlık olarak ekilen mercimek (Lens culinaris Medic.) bitkisinin biyolojik azot fiksasyon kapasitelerini tespit etmek ve sonar üzerine ekilecek olan buğday bitkisine ne miktar azot kazandırdığını belirlemek amacıyla bir tarla denemesi kurulmuştur. Birinci yıl, kışlık ve yazlık mercimek çeşitlerinin biyolojik azot fiksasyon kapasiteleri 15N metodu kullanarak tespit edilmiştir. İkinci yıl, baklagilden sonra ekilen buğdaya taşınan bakiye azot miktarları belirlenmiştir. Birinci yıl sonuçlarına göre, ortalama fikse edilen azot miktarları kışlık ve yazlık çeşitler için sırasıyla 70.0 ve 45.0 kgN/ha olarak bulunmuştur. İkinci yıl, baklagilden sonra ekilen buğdaya ortalama topraktan taşınan azot miktarları, ön bitki kışlık ve yazlık mercimek olduğunda, sırasıyla 43.0 and 17.0 kgN/ha olarak belirlenmiştir.
A field experiment was conducted using 15N methodology to estimate the biological nitrogen fixation capacities of winter and summer lentil (Lens culinaris Medic.) varieties and soil nitrogen conserving effect was observed following the cultivation of wheat under dryland conditions in Central Anatolia. First year, biological nitrogen fixation capacities of winter and summer lentil varieties were estimated by using 15N methodology. Second year, carry-over of N from the legume residue to wheat was determined. According to first year results, the average of fixed nitrogen were found as 70.0 and 45.0 kgN/ha for winter and summer varieties, respectively. Second year, the average of carry-over N derived from soil values were found 43.0 and 17.0 kgN/ha for succeeding wheat when the previous legumes were winter and summer lentil varieties, respectively.
