Abstract:
The field investigations entitled “Effect of Levels of Nutrients and Spacing on Growth and Yield of Pearl millet (Pennisetum glaucum L.)” was conducted during the zaid season of 2020 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology & sciences. Prayagraj. The experiment was laid out in randomized block design with 9 treatments which included T1 Control(N80:P40: K40 + 45 x 15), T2(N120:P75: K50+30 x 15), T3(N100:P60: K45+ 30 x 15), T4(N80:P40:K40+ 30 x 15),T5(N60:P30: K30 + 30 x 15), T6(N120:P75: K50+ 40 x 15), T7(N100:P60: K45 + 40 x 15), T8(N 80: P40: K40 + 40 x 15), T9(N60:P30: K30 + 40 x 15). The gross and net plot size of each experimental unit was 3 x3 m respectively. Sowing was done on 23April, 2020 by dibbling the seeds at spacing 40 x 15 cm and 30 x 15 cm. Maximum plant height (191.52 cm), Maximum No. of ears/m2 (4.04), No. of grains/head (2168.00), test weight (9.10), Grain yield (3.94 t/ha), Stalk yield (7.36 t/ha) were recorded with application of (N120:P75: K50+ 40 cm x 15 cm).Higher Gross returns (84831 ₹/ha), Net returns (50951 ₹/ha) and Benefit Cost Ratio (2.50) were obtained with application of (N120:P75: K50+ 40 cm x 15 cm).Hence, concluded that treatment no.6 (N120:P75: K50+ 40 cm x 15 cm) spacing was economically sound, preferred for farmers.
