Abstract: A field experiment was conducted to study the effect of different levels of nitrogen and phosphorus on growth and yield of Niger during Kharif season, 2002-2004 at Zonal Agricultural Research Station, Western Ghat Zone, Igatpuri Dist-Nasik (M.S.). Niger variety IGP-76 was sown in kharif season in randomized block design with twelve treatment and three replications. The plant spacing was 30x10 cm with plot size 3.60 x 2.40 m2. The soil of the experiment field was shallow laterite. The result revealed that the treatment T12 (N @ 40 kg/ha + P @ 40 kg/ha (20kg/ha through SSP + 20 kg/ha through RPen) +PSB) produced significantly higher seed yield of Niger (508 kg/ha), gross monetary returns (Rs.9295/ha) and net return (Rs.4626/ha) than rest of the treatments. However, application of N@40 kg/ha + P@20 kg/ha through SSP+PSB is followed to treatment T12 with seed yield of 502 kg/ha, gross monetary returns of Rs.8827/ha, Net return Rs.4519/ha and highest B:C ratio of 1:2.02. In spite of such significance the productivity of this crop is very low which may be enhanced by adequate and integrated management of nutrient supply especially phosphorus, because being oilseed crops niger responds well to phosphorus. It was concluded that the seed yield and ancillary characters were significantly influenced due to different levels and sources of phosphorus. It significantly produce higher seed yield than the control and rest of the treatment combinations, during both three years as well as in pooled analysis.
