Farklı Azot Dozlarının Karabuğdayın (Fagopyrum esculentum Moench) Tane Verim ve Kalitesine Etkisi

Araştırma; karabuğday için uygun azot dozunun (gübresiz-0 ve saf olarak: 1.5, 3, 4.5, 6 ve 7.5 kg/da) belirlenmesi ve azotun verim ve kaliteye etkisini araştırmak amacıyla 2014 yılında Isparta’da yürütülmüştür. Karabuğdayın en uzun bitki boyu (77.0 cm), en yüksek tane verimi (125.4 kg/da) ve biyolojik verim (431.3 kg/da) 7.5 kg/da N dozunda, en yüksek bin tane ağırlığı (24.2 g), agronomik etkinlik (11.91), geri dönüşüm etkinliği (67.74) ve yararlılık etkinliği (50.58) 6.0 kg/da N dozunda elde edilmiştir. En yüksek fizyolojik etkinlik (0.76) 4.5 kg/da N dozunda ve en yüksek agro-fizyolojik etkinlik (0.26) ise 1.5 kg/da N dozunda belirlenmiştir. Karabuğdayın mineral besin içeriği, uygulanan N dozlarının artışına bağlı olarak yükselmiş ve en yüksek N (%1.95), P (%0.216), K (%0.243), Mg (%0.131), Cu (4.53 ppm), Zn (18.59 ppm), Fe (3.7 ppm) ve Mn içeriği (3.00 ppm) 7.5 kg N uygulamasında tespit edilmiştir. Karabuğdayın mineral besin içeriği bakımından Fe elementi hariç 6.0 kg/da ile 7.5 kg/da azot dozları arasında istatistiksel olarak fark ortaya çıkmamış ve diğer elementler aynı grupta yer almışlardır.

Effects of Nitrogen Doses on Grain Yield and Quality of Buckwheat (Fagopyrum esculentum Moench)

The research was carried out to determination the suitable nitrogen doses (nonfertilizer: 0 and as pure: 15, 30, 45, 60 and 75 kg ha-1) and investigate the effects of nitrogen on yield and quality of buckwheat in Isparta during 2014. The longest plant height (77.0 cm), the highest grain yield (1254 kg ha-1) and biological yield (4313 kg ha-1) of buckwheat were obtained from 75 kg ha-1 N doses, while the highest 1000 grain weight (24.2 g), agronomic efficiency (11.91), recycling efficiency (67.74) and utilizing efficiency (50.58) from 60 kg ha-1 N doses. The highest physiological efficiency (0.76) was determined in 45 kg ha-1 N dose and the highest agro-physiological efficiency (0.26) from 15 kg ha-1 N dose. Mineral nutrient content of buckwheat was increased depending on increasing N doses, and the highest N (1.95%), P (0.216%), K (0.243%), Mg (0.131%), Cu (4.53 ppm), Zn (18.59 ppm), Fe (3.7 ppm) and Mn contents (3.00 ppm) were determined by 75 kg ha-1 N treatment. 60 and 75 kg ha-1 N doses were statistically the same significance in point of mineral nutrient content (expect for Fe) of buckwheat.
