Comparative effect of single and dual bio inoculants on microbial properties and quality of sunflower

Abstract

Liquid biofertilizer formulation is the promising and updated technology of the conventional carrier based production technology. Comparatively performance of liquid and carrier based bio-inoculants were studied for microbial count & quality parameters of sunflower. After harvest of sunflower and microbial properties also noted significantly better in bioinoculant treated plots as compared to uninoculated control and only RDF. Significantly higher values of actinomycetes population were noted in treatment received both the inoculants along with RDF in liquid form. However, in case of bacteria. and fungi dual inoculation with carrier based source (T5) and liquid source (T8) were noted statistically at par with each other. Through, liquid inoculants showed better performance but carrier based bioinoculants were also found equally at par with the respective N-fixer and P-solubilizer treatments. Quality in terms of oil yield, head diameter and number of seeds per head also improved with these bioinoculants.
