Effect of Integrated Nutrient Management on Growth Parameters and Productivity of Maize Cultivar PMH-5

The present study was undertaken to study the effect of INM on growth parameters and productivity of maize cultivar PMH-5. An investigation was taken up during kharif season of 2020-21 at the Instructional Farm, Rajasthan College of Agriculture, Udaipur. The experiment was laid down in factorial randomized block design (FRBD) with three replications. The treatments comprised of three levels of vermicompost, i.e. Control (VC0), Vermicompost @ 2.5 t ha-1 (VC1), Vermicompost @ 5 t ha-1 (VC2), four levels of chemical fertilizers i.e. Control (F0), 50 % RDF(F1), 75 % RDF (F2), 100 % RDF (F3) and two levels of biofertilizer, i.e. Control (B0), Azotobacter + PSB (B1). The results revealed that all plant growth parameters, grain, straw and biological yield of maize were found highest with the combined application of Vermicompost @ 5 t ha-1 (VC2)+ 100% RDF (F2)+ Azotobacter + PSB (B1) Respectively, which is statistically at par with combined application of Vermicompost @ 5 t ha-1 (VC2)+ 100 % RDF (F3) + Azotobacter + PSB (B1).
