 ABSTRACT

A field experiment was carried out during 2014-2015 at the Experimental Farm, Department of Horticulture, Assam Agricultural University, Jorhat to investigate the influence of microbial consortium inoculation on soil physico-chemical and biological properties with seven treatments and three replications in Randomized Block Design (RBD). The treatments were T1: FYM 20 t/ha + NPK @ 30:40:20 kg/ha (RDF), T2: Enriched compost @ 3 t/ha, T3: Enriched compost @ 3 t/ha + Consortium, T4: Vermicompost @ 3 t/ha, T5: Vermicompost @ 5 t/ha, T6: Vermicompost @ 2.5 t/ha + Consortium and T7: Consortium (Rhizobium + Azotobacter + Azospirillum + PSB). The results showed that inoculation of microbial consortium on french bean seed was significantly influenced by different treatments. The T3 recorded the best for all the soil parameters viz., soil moisture (18.72%), bulk density (0.83 g/cm3), pH (5.33) and P2O5 (47.40 kg/ha); T5 recorded highest organic carbon (0.68%); while T1 revealed maximum N and K (220.56 and 119.31kg/ha) content. In accordance with soil physico-chemical characters as found in T3 soil biological characters also found to be statistically superior in respect of microbial biomass carbon (630.33 μg/g/24h), dehydrogenase activity (711.50 μg TPF/g/24h), phosphomonoesterase activity (442.43 μg p-nitrophenol/g/h), fluorescein di-acetate hydrolysis activity (9.35 μg fluorescein/g/h). Similarly, T3 treatment was obtained with significantly higher bacterial population (8.55× 107 cfu g-1) and fungi population (5.03× 103 cfu g-1).

Key words: Microbial consortium, Soil, Physical, Chemical, Biological.
