Articles » Influence of Nitrogen and Phosphorus Fertilization on the Grain Characteristics of Buckwheat (Fagopyrum esculentum Moench)

ABSTRACT: In this study the influence of three levels of nitrogen (0, 100, and 150 kg/ha) and three levels of P (0,
50 and 100 kglba) fertilization on the grain characteristics (grain per plant, weight of lOOO seeds, grain
yield and protein of grain) of buckwheat (Fagopyrum esculentum) was studied, The results show that
nitrogen and phosphorous fertilization had a significant effect on the grain characteristics of
buckwheat plant. The highest seed per plant (3 g) weight of 1000 seeds (38.2 g) and seed yield (238.5
g per m2) was obtained from the plants were received 150 kglha nitrogen and 100 kglha phosphorus
fertilizer. Grain protein significantly affected by nitrogen and phosphorus fertilizer. The highest
protein content (9.5 and 9.4 g protein per m2) was measured from the grain was received 150 kg!ha N,
100 kg!ha P and 150 kg!ha N, 50 kg!ha P respectively. The most suitable NP-supply for production of
buckwheat to obtain the highest grain yield and protein content in suburb of Tehran, Iran is 150 kg!ha
nitrogen and 100 kg.tba phosphorus.
