10.22376/ijpbs.2019.10.1.p1-12 Volume 4 Issue 2 2013 (April - June) The application effect of different formulations of lessThan i greaterThan Pseudomonas lessThan /i greaterThan lessThan i greaterThan fluorescens lessThan /i greaterThan and lessThan i greaterThan Paenibacillus polymyxa lessThan /i greaterThan cells lessThan i greaterThan viz lessThan /i greaterThan ., single strain inoculation, co-inoculation and biofloc application together with challenge inoculation of lessThan i greaterThan Helminthosporium turcicum lessThan /i greaterThan on the enhancement of growth and yield parameters in maize with special emphasis to Induced systemic resistance (ISR) mediated biocontrol against leaf blight disease was studied under pot culture condition with maize cv. Co 1. The application of lessThan i greaterThan P. lessThan /i greaterThan lessThan i greaterThan fluorescens lessThan /i greaterThan and lessThan i greaterThan P. lessThan /i greaterThan lessThan i greaterThan polymyxa lessThan /i greaterThan cells, as biofloc, augmented the growth and yield parameters lessThan i greaterThan viz lessThan /i greaterThan ., plant height, root and shoot dry weight, phosphorous, carbohydrate, chlorophyll and IAA content, grain, stalk and cob yield of maize cv. Co 1 and altered the biochemical and physiological parameters of maize plant to a maximum level followed by co-inoculation and single strain application. Moreover, the application of lessThan i greaterThan P. fluorescens lessThan /i greaterThan and lessThan i greaterThan P. polymyxa lessThan /i greaterThan cells, as biofloc, increased the total phenol content and defense enzymes content of maize, reduced the reducing and non-reducing sugar content to a higher level that eventually lead to the reduction in lessThan i greaterThan H. turcicum lessThan /i greaterThan incidence in maize. The results of the present study clearly revealed the positive role of biofloc formulation of lessThan i greaterThan P. lessThan /i greaterThan lessThan i greaterThan fluorescens lessThan /i greaterThan and lessThan i greaterThan P. lessThan /i greaterThan lessThan i greaterThan polymyxa lessThan /i greaterThan cells on the enhancement of maize productivity and maximization of ISR mediated biocontrol in maize – lessThan i greaterThan H. lessThan /i greaterThan lessThan i greaterThan turcicum lessThan /i greaterThan pathosystem under semiarid condition together with a reduction in 25 per cent 'P' fertilizer application.
