Abstracts |
The study was conducted at the Agricultural Experimental Farm of the Indian Statistical Institute, Giridih, Jharkhand, India, during the winter season of 2007–2008 and 2008–2009. Baby corn cob and green fodder yields were greatest in T15 [100% recommended dose of fertilizers (RDF) + arbuscular mycorrhiza (AM) + Azospirillum]. Soil organic carbon (SOC) and residual soil fertility (NPK) were greatest in T16 (150% RDF + AM + Azospirillum). In contrast, soil microbial load [colony-forming units (CFUs) of bacteria, diazotrophs, fungi, and Azospirillum], AM biomass, soil respiration, microbial biomass carbon, metabolic quotient, microbial quotient, and enzymes (urease and acid phosphatase) were greatest in T13 (absolute control + AM + Azospirillum) followed by T14 (50% RDF + AM + Azospirillum)]. The values of all these parameters declined drastically with the increasing percentages of RDF. Coinoculated plots built up greater soil fertility and SOC. |
