EFFECT OF ROW SPACING AND SEED RATES ON THE YIELD OF BUCKWHEAT (FAGOPYRUM-ESCULENTUM)

A field experiment on buckwheat (Fagopyrum esculentum Moench) was cond ucted during the rainy seasons (kharif) of 1990 and 1991 under rainfed conditions at Ranichauri. Sowing of buckwheat at 30 cm gave the maxim um seed yield (18.35 q/ha), being 14.8 and 26.9% higher than 20 and 40 cm row spacings respectively. The highest stalk yield and harvest ind ex (15.97%) were recorded with 30-cm row spacing. The sowing of seed @ 30 kg/ha gave the maximum seed yield (18.36 9/ha), followed by 20 kg seed/ha. The stalk yield (98.38 q/ha) and harvest index (15.73%) were highest with 30 kg/ha seed rate.
