Effect of Nitrogen and Zinc Levels on Growth, Yield and Economics of Pearl Millet (Pennisetum glaucum L.)

Abstract

The field investigation entitled “Effect of nitrogen and zinc on growth, yield and uptake of Pearl millet (Pennisetum glaucum L.)” was conducted during kharif seasonof 2016-2017 at Agronomy Farm, COA, Latur. The experiment was laid out in Factorial Randomized Block Design with two factors and replicated thrice. Whereas first factor comprises levels of nitrogen viz. 0 (control), 45, 60 and 75 kg N ha^-1 and second factor levels of zinc viz. 05, 10 and 15 kg Z ha^-1. The recommended dose of fertilizer was applied at time sowing (60:30:30 NPK kg ha^-1 where N applied as per treatments). Processed seed sample were digested and N was determined by micro kjeldahal method as advocated by Piper (1966). Nitrogen content was calculated by multiplying N content by the factor 6.25. The application of nitrogen @ 75 kg N ha^-1 recorded significantly higher growth and yield attributes, gross monetary return, net monetary return and B:C ratio over the rest of the levels of nitrogen. Whereas NMR was remained at par with 60 kg N ha^-1. The application of zinc @ 15 kg Z ha^-1 produced significantly higher growth and yield attributes, gross monetary return, net monetary return and B: C ratio over the rest of the levels of zinc. Whereas, NMR was remained at par with 10 kg Z ha^-1.
