Abstract:
A field study was conducted during Kharif seasons of 2017-18 and 2018-19 at Research Farm, Department of Agronomy, CCSHAU, Hisar to evaluate temperature-based agrometeorological indices for pearl millet sown under different combinations of nutrient sources in pearl millet–wheat cropping system. The experiment consisted of twelve treatments (T₁ (Control),T₂ (50% recommended NPK), T₃ (50% recommended NPK in Kharif and 100% recommended NPK in Rabi), T₄ (75% recommended NPK), T₅ (100% recommended NPK), T₆ (50% recommended NPK + 50% N through FYM in Kharif and recommended NPK in Rabi), T₇ (75% recommended NPK+25% N through FYM in Kharif and 75% recommended NPK dose through fertilizers in Rabi), T₈ (50% recommended NPK + 50% N through wheat straw in Kharif and 100% recommended NPK in Rabi), T₉ (75%recommended NPK + 25% N through wheat straw in Kharif and 75% recommended NPK in Rabi), T₁₀ (50% recommended NPK+ 50% N through green manure in Kharif and recommended NPK in Rabi), T₁₁ (75% rec. NPK + 25% N through green manure in Kharif and 75% rec. NPK in Rabi) and T₁₂ (Farmer’s Practice)) and was laid out in RCBD design with four replications. Yield attributing characters and yield of pearl millet were recorded highest with the application of 50% recommended NPK + 50% N through FYM in Kharif and recommended NPK in Rabi. Nutrient application from both organic manures and fertilizers resulted in delayed in 50 percent flowering initiation stage.
