4 A field experiment was conducted for 3 consecutive years from 1989 to 1991 to find out the effect of sowing time on productivity and water use efficiency of niger (Guizotia abyssinica Coss.) genotypes. GA 10 produced the highest seed yield of 497.4 kglha which was 3.8 and 21.3% more over IGP 76 and UN 4, respectively. The crop sown on 20 August recorded higher yield (571.9 kg seed/ ha) than earlier or later sown crops. The moisture use efficiency was maximum for GA 10 (16.08 kg seed/ha/mm and 98.5 kg total yield/ha/mm. Sowing of the crop on 20 August proved efficient in utilizing soil moisture towards seed yield (19.78 kglhalmm) while 21 July sown crop resulted in the highest water use proved efficiency for total biomass yield (117.27 kglhdmm). GA 10 showed the maximum moisture use efficiency for its seed yield when sown on 20 August. .+-References
