Abstract:

 Nitrogen is a critical nutrient that is vital for enhancing plant growth and productivity. The influences of nitrogen N fertigation on yield, quality parameters, and nitrogen use efficiency of sweet corn Zea mays saccharata Sturt. under South Eastern Anatolia Region Diyarbakır conditions in Türkiye were investigated in that trial. Fertigation applications were executed under regional conditions in Diyarbakır during the 2015 and 2016 growing seasons on the experimental land of GAPUTAEM GAP International Agricultural Research and Training Center. The BATEM Batı Akdeniz Agricultural Research Institute Tatlı variety of sweet cornwas utilized as the plant material. Five different N applications 0-75-150-225-300 kg ha1 were implemented on trial plots through a fertigation system. N levels implemented via the fertigation system had a significant effect on the days of tasselling, plant height, fresh husked ear yield FHEY and fresh unhusked ear yield FUEY, chlorophyll rate, and nitrogen use efficiency p0.01. Fresh husked 1918 kg ha-1 and unhusked 1342.50 kg ha-1 ear yields of sweet corn under the effect of 150 kg ha-1 nitrogen treatment were the highest. The maximum chlorophyll rate was 53.14 recorded at 225 kg ha-1 N. Nitrogen use efficiency NUE increased with decreasing N supply, and the maximum NUE was observed from 75 kg ha-1 N application. The study findings indicate that the application of 150 kg N ha-1 using a fertigation method is important and environmentally conscious for the production of sweet corn.

 Azot, bitki yetiştiriciliği süresince eksikliği en çok hissedilen aynı zamanda en fazla ihtiyaç duyulan ve verimde artış sağlayan bitki besin elementlerinin en önemlisidir. Bu araştırma, fertigasyon yöntemiyle uygulanan farklı azot uygulamalarının 0-75-150-225-300 kg ha1 tatlı mısırın Zea mays saccharata Sturt. verim, verim parametreleri ve azot kullanım etkinliği açısından değerlendirilmek amacıyla Diyarbakır GAP Uluslararası Tarımsal Araştırma ve Eğitim Merkezi Müdürlüğü üretim alanında 2015 ve 2016 yıllarında yürütülmüştür. Çalışmada BATEM tatlı mısır çeşidi kullanılmıştır. Çalışma sonuçları incelendiğinde azot dozlarının çiçeklenme gün sayısı, bitki boyu, kavuzlu taze koçan verimi, kavuzsuz taze koçan verimi, klorofil oranı ve azot kullanım etkinliği üzerine önemli etkisi olduğu belirlenmiştir p  0.01. En yüksek kavuzlu taze koçan 1918 kg ha-1 ve kavuzsuz taze koçan 1342.50 kg ha-1 veriminin 150 kg ha-1 azot dozu uygulamasından, en yüksek klorofil oranı değerinin 53.14 ise 225 kg ha-1 azot dozu uygulamasından elde edildiği gözlemlenmiştir. Azot kullanım etkinliği değerinin azalan azot dozu uygulamaları ile artış gösterdiği ve en yüksek azot kullanım etkinliği değerinin 75 kg ha-1 azot dozu uygulamasından elde eldildiği görülmüştür. Çalışma sonucunda sürdürülebilir tatlı mısır yetiştiriciliği için fertigasyon yöntemiyle uygulanan 150 kg ha-1 azot dozu önerilebilir bulunmuştur.
