Abstract
Bu araştırma, Bursa ovası ekolojik koşullarında yetiştirilen sanayi tipi Rio Grande domates çeşidinde, değişik azotlu gübrelerin ve farklı azot dozlarının meyve verimi üzerindeki etkilerini belirlemek amacıyla, 1990-1991 yıllarında iki yıl süreyle yapılmıştır. Araştırma tesadüf bloklar deneme desenine göre üç tekerrürlü olarak kurulmuş ve dikimle birlikte bütün parsellere 10 kg P2O5/da hesabıyla triple süperfosfat, 10 kg K 0/da hesabıyla potasyum sülfat gübreleri verilmiştir. Dört azotlu gübre (amonyum nitrat, % 26 N; amonyum sülfat, % 21 N; üre, % 46 N; Kompoze (25:5:0)) üç farklı zamanda ve dört ayrı dozda (0, 10, 14 ve 18 kg N/da) uygulanmıştır. Araştırmanın 1991 yıl sonuçlarına göre, domatesin meyve verimi üzerine amonyum nitrat, amonyum sülfat ve 25:5:0 gübrelerinin etkileri ayni düzeyde gerçekleşirken, üre gübresinin etkisi bu gübrelerden daha uz olmuştur. Domatesin meyve verimi üzerinde de en etkili azot dozlarının 14 kg N/da ve 10 kg N/da olduğu belirlenmiştir.
This research was implemented to investigate the effects of various nitrogen sources and different nitrogen doses on the yield of processing tomato c.v. Rio Grande in the years of 1990 and 7991 at the ecological conditions of Bursa region. The field experiment was conducted in randomized block design with three replications. As base fertilization, 10 kg P2O5/da (triple superphosphate), 10 kg K2O/da (potassium sulphate) were applied to each of the plots. Four different nitrogen fertilizers (ammonium nitrate, 26 % N; ammonium sulphate, 21 % N; Urea, 46 % N; Compound fertilizer (25:5:0)) were applied to the plots of four levels (0, 10, 14 and 18 kg N/da) at three stage. According to the results of the experiment in 1991, the effects of ammonium nitrate, ammonium sulphate, and 25:5:0 on the field were found to be similar. The effect of urea on the yield however, was lower than the upper mentioned fertilizers. As to the nitrogen levels 14 kg N/da and 10 kg N/da produced statistically more yield than the other levels.
