İklim faktörleri ve farklı azot dozlarının mısır bitkisinde verim ve azot kapsamına etkisi

Abstract

In this study, effects of humid and subhumid conditions on yield and N content were investigated in the application of nitrogen fertilization. Functional relationships among N fertilizer doses, grain and straw yield depending on climatic conditions, and different amount of grain yield with fertilizer applications were determined. The relationships for grain yield were determined with respect to fertilizer doses, hydrothermic constant (HTC) and precipitation amount. Theoretical maximum yield amount was determined from these relations. When amount of nitrogen fertilizer was 22.68 kg/da and HTC0.504, maximum yield was estimated as 1043.63 kg/da. When total precipitation amount was 126.1 mm and amount of nitrogen fertilizer was 22.69 kg/da in the same vegetation period (June - September), maximum yield was estimated as 945.21 kg/da.

Bu çalışmada nemli ve yarı nemli iklim koşullarının azotlu gübre uygulandığında ürün ve azot kapsamına olan etkisi araştırılmıştır, iklim koşullarına bağlı olarak azotlu gübre dozları ile dane ve sap ürün miktarları arasındaki fonksiyonel ilişkiler ile gübre uygulamasına göre farklı miktarda dane ürününün elde edilebilme olasılığı belirlenmiştir. Dane verimi ile gübre dozları, hidrotermik katsayı (HTK) ve yağış miktarı arasındaki ilişkiler bulunarak, teorik maksimum ürün değerleri hesaplanmıştır. Azotlu gübre miktarı 22.68 kg/da ve HTK0.504 olduğunda maksimum ürün miktarı 1043.63 kg/da olarak, aynı vejetasyon dönemindeki (Haziran-Eylül), toplam yağış miktar 126.1 mm ve azotlu gübre miktarı 22.69 kg/da düzeyinde alındığında ise maksimum ürün miktarı 945.21 kg/da olarak hesaplanmıştır.
