Title Of Article :
Development of microbial consortia for growth improvement of neem
Abstract :
Arbuscular mycorrhizal fungus (AMF), such as Funneliformis mosseae, is the best microorganism for inoculating neem. We investigated the interaction between selected F. mosseae and five different plant growth-promoting rhizomicroorganisms (PGPR). The results indicate that the microbial consortia comprising F. mosseae and PGPR Paenibacillus polymyxa is the best for enhancing the growth and nutrition of neem seedlings under glass house conditions. Large scale forest nursery trials at Mandya district, Karnataka state, India, using 500 inoculated and 500 uninoculated neem seedlings, validated the results of the glass house study. The inoculated seedlings had 39% (average of 3 locations) higher bio-volume index (BI) when compared to that of the uninoculated seedlings. The uninoculated and inoculated seedlings, under large scale nursery trials, were out-planted in wastelands at 3 locations and their growth parameters were evaluated after 8 months. After 8 months of out-planting, the BI of plants inoculated with microbial consortia was 29% higher (average of 3 locations) than that of the uninoculated plants.
