ABSTRACT
The aim of the present investigation was to analyze the effect of biocontrol agents and polymer coating under hydroponic culture. The longest root length (15.2 cm), shoot length (23.5 cm), more number of leaves (17 nos.), secondary (55 nos.), tertiary roots (38 nos.) and chlorophyll index (27.9) with better seedling quality attributes were observed in biopriming with 6 per cent Bacillus amyloliquefaciens + polymer coating compared to other biopriming, dry seed treatment and control. These results were also confirmed by serial dilution technique using seed and wash root tip of the treated with seedlings, higher bacterial population of 25 x 108 cfu ml-1 and 37.7 x104 cfu g-1 respectively. Better result was also observed in biopriming with 8 per cent P. fluorescens + polymer coating compared to other treatments.
