Effect of integrated nutrient management on growth and yield attributes of maize under winter season (Zea mays L.)

Abstract

An experiment was conducted during Rabi season of 2016-2017 at Research Farm of the Department of Agriculrure, Mata Gujri College, Fatehgarh Sahib to study the Effect of integrated nutrient management on growth and yield attributes of maize under winter season (Zea mays L.)”. The experiment was laid out in randomized block design with eight integrated nutrient management treatments viz. T2- 100% RDF, T3- 50% RDF + PSB + vermicompost (2.5t/ha), T4- 75% RDF + vermicompost (5t/ha), T5- 50% RDF + FYM (5t/ha) + vermicompost (5t/ha), T6- 50% RDF + FYM (10t/ha) + azotobacter, T7- 75% RDF + vermicompost (5t/ha) + FYM (5t/ha) + azotobacter and T8- 75% RDF + azotobacter + PSB were compared with T1- control. The treatments were replicated thrice. On the basis of results summarized at 30 DAS, the maximum growth were recorded with application of T2- 100% RDF which was at par with T7- 75% RDF + vermicompost (5t/ha) + FYM (5t/ha) + azotobacter and T4- 75% RDF + vermicompost (5t/ha). However at 60, 90 DAS and at harvest stage, the application of T7- 75% RDF + vermicompost (5t/ha) + FYM (5t/ha) + azotobacter gave best result in term of growth character and yield which is statistically at par to application of T2- 100 % RDF and T4- 75% RDF + vermicompost (5t/ha). Application of 75% RDF + Vermicompost (5 t/ha) + FYM (5 t/ha) + azotobacter gave the maximum net returns of Rs. 84272 ha and maximum benefit: cost ratio is observed in T7- 75% RDF + Vermicompost (5 t/ha) + FYM (5 t/ha) + azotobacter is 1.49.
