A field experiment was conducted on sandy soils at Agricultural Research Station, Radhanpur (North Gujarat) during 2003-2006 to ascertain the effect of bio-fertilizer, various organic sources alone or along with inorganic fertilizers on productivity of pearl millet and post harvest soil fertility under rain fed condition. There were twelve treatments involving inorganic, organic and bio fertilizers (Azotobacter/Azospirilum and PSM ). All the treatments of nutrient management found significantly superior over absolute control. Maximum yield (1920 kg/ha), total income, net realization (Rs. 16709/ha) and BC Ratio (2.75) were obtained due to application of recommended dose of NP fertilization (80:40 NP kg/ha) along with gypsum @ 250 kg/ha .The maximum uptakes of N, P and K by pearl millet were significantly affected and recorded maximum with application of NP fertilization+gypsum @ 250 kg/ha. The available phosphorus and DTPA extractable micronutrients status after harvesting of crop were significantly affected due to different treatment.

Abstract


A field experiment was conducted on sandy soils at Agricultural Research Station, Radhanpur (North Gujarat) during 2003-2006 to ascertain the effect of bio-fertilizer, various organic sources alone or along with inorganic fertilizers on productivity of pearl millet and post harvest soil fertility under rain fed condition. There were twelve treatments involving inorganic, organic and bio fertilizers (Azotobacter/Azospirilum and PSM ). All the treatments of nutrient management found significantly superior over absolute control. Maximum yield (1920 kg/ha), total income, net realization (Rs. 16709/ha) and BC Ratio (2.75) were obtained due to application of recommended dose of NP fertilization (80:40 NP kg/ha) along with gypsum @ 250 kg/ha .The maximum uptakes of N, P and K by pearl millet were significantly affected and recorded maximum with application of NP fertilization+gypsum @ 250 kg/ha. The available phosphorus and DTPA extractable micronutrients status after harvesting of crop were significantly affected due to different treatment.
