Influence of Integrated Approach of Azotobacter and Nitrogen Fertilizer on Various Morpho-Physiological and Biochemical Parameters of Brassica Oleracea L. var. capitata

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.
