Abstract

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.

Farklı Azot Dozlarının Karabuğdayın (<i>Fagopyrum esculentum Moench</i>) Tane Verim ve Kalitesine Etkisi

Abstract

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.
