Abstract
For mobilizing fixed soil potassium, a carrier based novel potassium solubilizing bio-formulation containing Penicillium pinophilum, MCC0114 was developed and evaluated for its effect on availability of K and P, nutrient uptake, fruit yield and quality of pomegranate under field condition. Soil inoculation with this bio-formulation at the rate of 10 g tree-1 (incubated with 200 g well decomposed cow dung manure) twice once during rest period and other at stress release was found to improve availability of K and P in soil, nutrient uptake (N, P and K) that resulted in improved growth, significantly higher leaf area index, photosynthetic activity of tree and increased fruit yield by 35% with perceptible improvement in fruit quality. The impact of bio-formulation on fruit yield and quality was much higher, when supplemented with insoluble K bearing mineral. This is patented technology and has been commercialized to private companies.
