Abstract:An experiment entitled “Studies on influence of bio-fertilizers and level chemical fertilizers on growth of Onion (
Allium cepa L.)
cv. Bhima Red” was carried out at Agricultural Farm, Krishi Vigyan Kendra, Dhar, M.P. during 2020-21 and 2021-22 with the objectives to study effect of bio-fertilizers application on growth characters. The experiment was conducted in Randomised Block Design with 3 replications. It comprised of 14 treatments of bio-fertilizers and levels of chemical fertilizers.
Growth parameters like Leaf area(cm2) at 30, 60, 90 and 120 DAT, Leaf area index at 30, 60, 90 and 120 DAT, Bulb/green top ration, Leaf dry matter, Chlorophyll content in leaves and Bulb dry matter were recorded and statistically analysed. From the experiment, it may be concluded that the bio-fertilizers and various levels of chemical fertilizers had a significant effect on the growth of the crop. The treatment with 100% RDF + Azospirillum + Azotobacter + VAM was found the best treatment among all treatments whereas the minimum effect was observed under treatment with no bio-fertilizer and chemical fertilizer.
