Abstract

This study was formulated to evaluate the impact of bacterization with Azotobacter of two cabbage genotypes (Pusa Early golden acre and Pusa drum head) under field conditions. The study was performed in herbal garden of Jamia Hamdard, New Delhi. The plants were treated with graded treatments (60,120,180 kg N ha-1) of N alone and in combination with seedling inoculation withAzotobacter. The plants were sampled and tested for various morpho-physiological and biochemical parameters. Chlorophyll content, NR activity, protein content, sugar content and phenol content was found to be significantly higher in plants treated with N in combination in Azotobacter. Thus, the use of Azotobacteras a supplement or biofertilizer in integrated nutrient management systems was highly recommended to minimize the application rates of synthetic fertilizers and attain the goal of sustainable agriculture.

Highlights

Food security is one of the critical challenges we are facing today.[1]
This rise in shoot fresh weight may be attributed the ability of the plant to assimilate the given nitrogen into proteins and other necessary metabolites
The experiment was designed to find out the effect of various levels of nitrogen and Azotobacter with its interaction effects to find out the best combination of different treatments to achieve maximum economic returns on growth, yield and quality of cabbage

Summary

Introduction

Food security is one of the critical challenges we are facing today.[1] agricultural lands have been over exploited for centuries; and its fall outs are soil degradation, erosion, and increased greenhouse gas emissions, due to higher dependency on agronomic inputs.[2] Some of the proposed options for improving soil fertility include organic amendments, no-till farming, use of bio-fertilizers and integrated nutrient management system.[3] World agricultural output has tremendously increased since 1950’s by the effort of scientific community to ensure food security. During the last few years, bio-fertilizers have appeared as an imperative part of integrated nutrient management system and seems a promising
