Effect of Phosphorus and Zinc on Yield and Economics of Pearl Millet (Pennisetum glaucum L.)

Abstract

Phosphorus and zinc effects on pearl millet variety 'ABV-04' during the rainy season (Kharif) of 2021 were studied in field experiments with nine treatments, i.e., P at 30, 40, 50 kg/ha and Zn at 5, 15 and 25 kg/ha respectively, at Crop Research Farm, Department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, India (U.P). The treatments comprised T1 – 30 kg P/ha + 5 kg Zn/ha, T2 – 30 kg P/ha + 15 kg Zn/ha, T3 – 30 kg P/ha + 25 kg Zn/ha, T4 – 40 kg P/ha + 5 kg Zn/ha, T5 – 40 kg P/ha + 15 kg Zn/ha, T6 – 40 kg P/ha + 25 kg Zn/ha, T7 – 50 kg P/ha + 5 kg Zn/ha, T8- 50 kg P/ha + 15 kg Zn/ha, T9 – 50 kg P/ha + 25 kg Zn/ha. Results revealed that the application of 50 kg P + 25 kg Zn recorded highest ear head length (18.90 cm), maximum grain production (2.66 t/ha), maximum stover yield (3.90 t/ha), highest gross and net returns of (1,33,667.00₹) and (92,861.00₹), respectively. b.c ratio (2.26) was also found.
