10.22376/ijpbs.2019.10.1.p1-12 Volume 8 Issue 2 2017 (April - June) In the present study, we attempted to improve the growth and health of tomato ( lessThan i greaterThan Lycopersicon esculentum lessThan /i greaterThan Mill.) using talc based formulations of two beneficial rhizobacteria ( lessThan i greaterThan Bacillus subtilis lessThan /i greaterThan PSIRB2 and lessThan i greaterThan Pseudomonas aeruginosa lessThan /i greaterThan 2apa). These isolates were well characterized for their beneficial traits in our previous studies. Shelf life of talc-formulation of isolate 2apa was found stable up to 60 days, afterwards a drastic decrease was observed with the storage period at room temperature. The population of PSIRB2 decreased gradually throughout the experimental period of 120 days to 0.25 × 10 lessThan sup greaterThan 7 lessThan /sup greaterThan cfu/g formulation. Growth promotion studies under laboratory and greenhouse conditions revealed that the talc-formulations of both the test bacteria as good as fresh cultures in increasing the growth variables, in comparison with control. Similarly, PSIRB treated seedlings (both talc-formulation and fresh culture) recorded significantly ( lessThan i greaterThan P lessThan /i greaterThan ≤ 0.05) higher nutrient uptake. Under greenhouse conditions isolate 2apa recorded significant ( lessThan i greaterThan P lessThan /i greaterThan ≤ 0.05) disease protection in both talc-formulation and fresh culture form against Fusarium wilt and Early blight diseases of tomato.
