Studies on Stover Yield of Maize with Basal Application of Fertilizer and Foliar Spraying of Gluconacetobacter diazotropicus on Available Nutrients in Soil

The experiment on “Studies on Stover yield of maize with basal application of fertilizer and foliar spraying of Gluconacetobacter diazotropicus on available nutrients in soil” was carried out during Kharif 2022 in the experimental filed under Department of Soil Science & Agricultural Chemistry. The experiment was carried out according to a randomized block design (RBD) with 3 replication including 18 treatments of the microbial consortium Arthrobacter sp., phosphate-solubilizing bacteria (Bacillus sp.) and soluble bacteria. There is also Gluconacetobacter diazotrophicus sprayed on leaves at 25, 45 and 65 DAS of the plant growth stages. Maize seeds (cv. JM 216, duration 110 days, sowing 20 kg/ha) were sown in the specified plot (size 3mx2m) on June 28, 2022, with a distance of 60 and 20 cm. Plants are supplemented with the recommended dose of fertilizer 120:60:40 (Nitrogen:P2O5:K2O kg/ha) in basic fertilization. Additionally, two types of control plots were maintained: fertilized un-inoculated (FUI) control plots and un-inoculated (UFUI) control plots. Regarding the study of main nutrients in the soil at harvest time, the combination of similar treatments also increased N, P and K by 21.31, 21.31 and 60.6%, respectively. The most effective treatment was performed systematically by a combination of RDF+Arthro+PSB+KSB treatments for all parameters. Simultaneous inoculation of biological products G. diazotropicus, Arthrobacter, PSB (Bacillus sp.) and KSB (Frateuria aurantia) when treating seeds and foliar fertilizing maize increased growth and the ability to provide important nutrients in the soil at harvest time. This is the positive impact of G.diazotropicus and Arthrobacter The data on stover yield ranged from 5618- 10729 kg/ha. All the treatments (except G. diazotropicus) increased significantly the grain yield over the control fertilized uninoculated (FUI). Among all the treatment combinations.
