Efficiency of Different Nitrogen Forms in Buckwheat (Fagopyrum esculentum Moench)

Burhan Kara, Fatoş Güllü Çelebi, Nimet Kara, Bekir Atar


The research was carried out with aim to determination the efficient of nitrogen forms (ammonium sulfate, ammonium nitrate and urea) on nitrogen use efficient for buckwheat in Isparta during 2014 and 2015 years. All the examined characteristics were determined higher values in applied nitrogen forms according to non-nitrogen parcel. In compared to nitrogen forms, the highest grain yield (1456 and 1325 kg ha-1), biological yield (4873 and 4512 kg ha-1), 1000 grain weight (24.9 and 24.8 g), agronomic efficient (24.96% and 24.25%), recycling efficient (0.24% and 0.22%) and utilization efficient (0.25% and 0.18%) were obtained from ammonium sulfate, the highest protein content (11.37% and 12.44%) and agro-physiological efficient (0.27% and 0.24%) from ammonium nitrate in both years. Among the nitrogen forms weren’t significant differently in physiological efficient in both years, recycling and utilization efficient in the first year. The mineral nutrient content varied according to nitrogen forms. Generally, ammonium sulfate was positive effect to yield and some quality parameters.
