Abstract
In this research, the effect of furrow and drip irrigation method and 4 different N dosage to the yield and yield components of sunflower were examined. AS.503 sunflower variety as a test crop, ammonium sulphate (%21 N) and ammonium nitrate (%33 N) manure for N source were used. This research, including furrow and drip irrigation4 N dosage (0-3-İ0-15 kgNda"1) with 4 tines repeating (2X4X4) were carried out in 32 plot of land with using split pilot method between 1998-1999 for 2 years. The main object of this research, half of the N dosage were applied as ammonium sulphate (%21 N) form, while the preparing of land, the other half of the dosage were applied as ammonium nitrate (%33 N) form, while the crop Karık ve Damla Sttîamâ Metodlan tie Farklı Azot Dozlarttim Ayçiçeğinde............. reach 25-30 cm length. When the crop had reached 4-6 leaf period, the irrigation was started mid irrigation period were determined based on land moisture decreased into % 50. For both irrigation method, the needs of water which determined were applied in control after double-check with using meter. In harvesting time, while the crops that reached harvesting level, were harvested meanwhile, yield, 1000 seed weight, diy material, huie ratio, plant height, head diameter, stem diameter, stem yield, seed length and oil ratio were determined. It the conclusion, statistical analysis were applied to the 2 years data and with using drip irrigation method and 10 kg N dosage were found as preferable.
Özet
Araştırmada, karık ve damla sulama metodlan ile 4 değişik azot dozunun, ayçiçeğinde verim ve verim unsurlarına etkisi incelenmiştir. Materyal olarak AS.503 ayçiçeği çeşidi, azot kaynağı olarak ise amonyum sülfat (%21 N) ve amonyum nitrat (%33 N) gübreleri kullanılmıştır. Araştırma; kank ve damla sulama metodlan, 4 azot dozu (0-5-10-15 kgN/da) ve 4 tekerrür olmak feere (2X4X4) 32 parselli tesadüf parsellerinde bölünmüş parseller deneme desenine göre 1998-1999 vîllannda 2 yıl süreyle yürütülmüştür. Araştırma konusu olaıı azot dozlarının 1/2'si tarla hazırlığında amonyum sülfat (%21 N) formunda 1/2'si ise amonyum nitrat (%33 N) formunda, bitkiler 25-30 cm boyuna geldiğinde uygulanmıştır. Bitkiler; 4-6 yaprak olduklarında sulamayabaşlanmış ve sulama peryotlân, toprak neminin %50'ye düşmesine göre belirlenmiştir. Her iki sulama metodunda da belirlenen su ihtiyacı sayaçtan geçirilerek kontrollü verilmiştir. Hasat olgunluğuna gelen bitkiler hasat edilirken; dane verine bin dane ağırlığı, yağ oram, kuru madde, iç oranı, dane boyu, tabla çapı, bitki boyu, sap çapı, sap verimi belirlenmiştir. Araştırmada verilere ait iki yıllık ortalamalar istatistik! olarak değerlendirilmiş ve damla sulama metodu ile 10 kg.N da" dozu tercih edilebilir bulunmuştur.
