SUMMARY

A field experiment was carried out at Dryland Agriculture Research Farm of the Chaudhary Charan Singh Haryana Agricultural University, Hisar during Kharif season of 2019 to study the nutrient management impact on grain and stover quality and nutrient uptake of pearl millet [Pennisetum
glaucum (L) R.Br.] under rainfed condition. The experiment consisted of thirteen nutrient management practices viz. T₁– control, T₂– 40:20 kg NP/ha, T₃– 50:25 kg NP/ha, T₄– 60:30 kg NP/ha, T₅– 40:20:10 kg NPK/ha, T₆– 50:25:12.5 kg NPK/ha, T₇– 60:30:15 kg NPK/ha, T₈– 40:20:10 kg NPK/ha + ZnSO₄ @ 0.5% at 30 DAS, T₉– 50:25:12.5 kg NPK/ha + ZnSO₄ @ 0.5% at 30 DAS, T₁₀– 60:30:15 kg NPK/ha + ZnSO₄ @ 0.5% at 30 DAS, T₁₁– 40:20:10 kg NPK/ha + 0.5% ZnSO₄ + 0.5% FeSO₄ at 30 DAS, T12- 50:25:12.5 kg NPK/ha + 0.5% ZnSO4 + 0.5% FeSO4 at 30 DAS and T13- 60:30:15 kg NPK/ha + 0.5% ZnSO₄ + 0.5% FeSO at 30 DAS was laid out in randomized block design with three replications. Results revealed that application of 60:30:15 kg NPK/ha + 0.5% ZnSO₄ + 0.5% FeSO₄ at 30 DAS enhanced grain and stover quality of pearl millet in terms of protein, iron, zinc content and protein yield under rainfed condition. The maximum N, P and K uptake by grain (28.66, 8.60 and 13.00 kg/ha, respectively) and stover (20.52, 3.20 and 62.07 kg/ha, respectively) of pearl millet was recorded by application of 60:30:15 kg NPK/ha + 0.5% ZnSO₄ + 0.5% FeSO₄ at 30 DAS among all the treatments. The total uptake of N (49.18 kg/ha), P (11.80 kg/ha) and K (75.07 kg/ha) was found highest with the application of 60:30:15 kg NPK/ha + 0.5% ZnSO₄ + 0.5% FeSO₄ at 30 DAS over rest of treatments.
