Effect of integrated nutrient management with Azotobacter on growth and yield on maize (Zea mays L.) Var. K-65

Abstract

A field experiment was conducted to study the effect of INM with Azotobacter on growth and yield of maize var. K-65 at Crop research farm Department of Soil Science & Agriculture Chemistry, Naini Agriculture Institute, SHUATS Prayagraj. The experiment was laid out in randomized complete block design with eight treatments each replicated three times. Analysis of variance showed that growth and yield were significantly affected with treatments. The application of T8 @ 100% NPK + @ 100% Azotobacter gave significantly higher plant height 170.70cm, number of leaves plant-1 15.85 and leaf length 57.47cm, dry weight of plant 173.36g, length of cob 17.73cm, number of grains cob-1 308.76, number of grains cob-1 204.57, test weight g 215.76 and grain yield 38.42 q ha-1.
