Effective in-situ moisture conservation is possible only by appropriate soil manipulation technology to capture and harness the rainwater. A field experiment was conducted to study the impact of in situ moisture conservation practices (tillage) and nitrogen supply from various sources on the performance of pearl millet in respect of yield and energy use pattern at Research Farm, R.B.S. College, Bichpuri, Agra (U.P.), for two years. Among the different tillage practices deep tillage + two interculture gave significantly superior results in respect of grain and stover yield. Deep tillage + two interculture treatment recorded 24.62, 18.50 and 17.84 percent higher grain yield than minimum tillage+ one interculture + two interculture and minimum tillage + one intercultur + weedicide application treatments respectively. Application of 100% nitrogen through inorganic source gave significantly higher yield of grain and stover than application of 100% nitrogen through organic source and application of 50% nitrogen through organic source + 50% nitrogen through inorganic source. Maximum water use efficiency was recorded under deep tillage both for grain (7.54 kg ha ha-1 mm-1) and stover (18.30 kg ha-1 mm-1). Application of nitrogen through different sources not much influenced the water use efficiency during both the seasons. The energy use pattern revealed that deep tillage with two interculture consumed more energy (8021 MJ ha-1) and minimum tillage with one interculture consumed less energy (6766 MJ ha-1). Deep tillage also gave higher value of output-input energy ratio and lower value of specific energy. The variation in total input energy consumed in growing of pearl millet crop was not observed due to application of nitrogen through different sources. Application of 100% nitrogen through inorganic source gave higher value of output-input energy ratio and lower value of specific energy.
