EFFECT OF FORMULATED BIOFERTILIZER ON GROWTH AND NUTRIENT UPTAKE OF WHEAT (TRITICUM AESTIVUM L.)AARTI YADAV, POOJA AND SUNITA SUNEJA
The availability of phosphorus in soil can be enhanced by the inoculation of phosphate solubilizing microorganisms along with rock phosphate. The success of such solubilization is largely depending on the capacity of the bioinoculant to survive under unfavorable environmental conditions. In this context, liquid inoculants are gaining importance and are becoming an alternative way with longer shelflife and field efficacy. In the present investigation, a preliminary study was conducted to check the comparative effect of phosphate solubilizing bacterial (PSB) bioinoculant formulated with different additives (glycerol, polyvinypyrrolidone, gum arabic) which supports growth and promote survival of bioinoculants. Seeds were inoculated with 90 days old bacterial bioinoculants with various treatments stored at refrigerator and room temperature. PSB inoculants formulated by different additives significantly enhanced plant growth, yield, nutrient content and their uptake in wheat at 120 days of growth as compared to uninoculated control/treatment.
