Abstract

Phosphate solubilizingbacteria are known to play a major role in the solubilization of unavailable forms of soil phosphorus and uptake its native and applied forms. A total of 17 different Pseudomonas flourescens isolates recovered from rhizosphere and J.curcas, planted in different localities, were evaluated for their phosphatase activity in in vitro and in vivo conditions. Isolates viz., P#10, P#l1 and P#02 revealed maximum phosphatase enzyme activity and influence the maximum growth and therefore can be used as bioinoculant in nursery and field trials for better production of J.curcas.

Abstract

Effect of ischolar_main exudates on AM colonization in Jatropha curcas was studied in the current work. Total three treatments were tested viz., ischolar_main exudates + AM fungi, AM fungi alone, and ischolar_main exudates alone. Out of which the treatment containing AM fungi + ischolar_main exudates showed maximum (75%) colonization followed by AM fungi alone. Impact on plant nutrient status was also observed and significant results were recorded. There was remarkable enhancement in phosphatase enzyme activity, phosphorus uptake and leaf protein in treatment containing AM fungi and ischolar_main exudates as compared to control. Therefore, from the present findings, it can be concluded that ischolar_main exudates affect the ischolar_main colonization of AM fungi which in turn improve the growth and development of biofuel plant J.curcas.
