Influence of nutrient levels on pearl millet (Pennisetum glaucum L.) growth, yield and economics under dryland condition of Northern Karnataka

Abstract

The present study was conducted at Regional Agricultural Research Station, Vijayapur during kharif 2018 and 2019 in medium black soil. The experiment was designed in a split plot design comprising four pearl millet hybrids as main plots (VPMH 7, VPMH 8, GHB 558 and 86M88) and three nutrient levels (100% RDF, 125% RDF and 150% RDF) in sub plots, replicated thrice. Pearl millet hybrids VPMH 8, 86M88 and VPMH 7 were better in growth compared to GHB 558. Growth parameters were statistically superior in 150% and 125% RDF compared to 100% RDF. Grain and dry fodder yield were higher in 86M88 (2285 and 5210 kg ha-1, respectively) and VPMH 8 (2255 and 4772 kg ha-1, respectively) than GHB 558. Nutrient level at 150% RDF has recorded higher grain and dry fodder yield, respectively (2367 and 5143 kg ha-1) and was on par with 125% RDF (2186 and 4931 kg ha-1). Higher gross and net returns were recorded by 86M88 (Rs. 34,275.00 and 21,488.00, respectively). RDF at 150% and 125% have recorded higher net returns and B:C ratio.
