AbstractThe association between a selected strain of Azotobacter chroococcum and seven plants was investigated in water cultures under sterile conditions. Azotobacter population progressively increased in the nutrient solution and on the rhizoplane. Microbial propagation depends on the type of plant, being much higher in presence of wheat, followed by barley, maize, broad bean, and cotton, while in presence of fenugreek and lentil lower rates of multiplication were recorded. Inoculation increased the dry weight of plants by 5--12% and in length by 3--18% in addition to increased nitrogen content of plants and nutrient solution. Nitrogen balance showed no significant change in systems devoid of Azotobacter, but association between plants and the microorganism invariably showed positive results. The extent of N2-fixation depends on the type of plants; higher gains were recorded in presence of non-leguminous plants.

AbstractThe validity of seed bacterization with Azotobacter chroococcum in soils of variable densities of naturally present azotobacters was studied. Inoculation of barley grains had no effect on counts of total microflora, neither in rhizosphere nor in root-free soil, but significantly increased Azotobacter population, especially in the rhizosphere. The rate of colonization in the root region was much higher when soil initially harboured low Azotobacter densities. Bacterization improved plant growth and increased soil nitrogen through nitrogen fixation. Nitrogen balance in soils showed higher gains in the inoculated treatments over the uninoculated analogues of 30--98 ppm.
