Abstract:

One of the successful, effective and safe methods to enhance phosphorus use efficiency (PUE) is coating of diammonium phosphate (DAP) with alginate-entrapped bacteria (Enterobacter spp. MN17) which not only release microbes and phosphorus (P) slowly in soil but also protect microbes from soil stresses and P from fixation in soil. Present study was conducted with key aspects of alginate as endophytic microbes carrier, potential to maintain cell viability on DAP surface, effect on P release pattern and nutrients uptakes of wheat. MN17 survival rate was well documented in prototype solution {(alginate 1.5%) + (1% glucose + 1% glycerol)} and DAP surface. Phosphorus (419, 656, 978 and 1081 mg kg-1 soil) and microbe (92, 120, 118 and 110×106 CFU g-1 soil) release pattern was observed at 15, 30, 45 and 60 days (d)soil sampling from alginate-entrapped MN17 coated DAP. An enhancement of plant height (36-48%), chlorophyll contents (30-41%), grains yield (31-70%), P agronomic efficiency (57-107%), grains P concentration (39-45%) as well as micronutrients concentration in grains was recorded in treatment receiving alginate-entrapped MN17 coated DAP at recommended rate over uncoated DAP. Our study first time explores the multiples benefit of alginate entrapped endophytic bacteria coated DAP in effective microbes delivery at target site, nutrient management and quality improvement of wheat crop.
