Integrated nutrient management in pearl millet (Pennisetum glaucum)–wheat (Triticum aestivum) cropping system

Abstract

A field experiment was conducted during 2014–15 and 2015–16 at Swami Keshwanand Rajasthan Agriculture University, Bikaner, Rajasthan, to evaluate the effect of integrated nutrient management on yield of wheat (Triticum aestivum L.) and succeeding pearl millet [Pennisetum glaucum (L.) R. Br.] crop. The experiment was laid out in a split-plot design with 3 replications comprising different treatment combinations. Incorporation of 75% recommended dose of fertilizer (RDF) + 5 t farmyard manure (FYM)/ha + Azotobacter + phosphate-solubilizing bacteria (PSB) in wheat, significantly increased yield attributes and yield (4.12 t/ha) of wheat and uptake of nutrients (N, P, K) in both grain and straw of wheat, but remained at par with 100% RDF + 5 t FYM/ha + Azotobacter + PSB. The yield of succeeding pearl millet was significantly higher under all INM (integrated nutrient management) treatments applied in preceding wheat over the control and 100% RDF.
