ABSTRACT

Field experiment was conducted during kharif 2008. The experiment was laid out in a split plot design replicated thrice. Three fertilizer levels viz., 150:75:75, 200:100:100 and 250:125:125 kg NPK ha-1 were the main plot treatments. Foliar spray of growth substances viz., control (no spray), salicylic acid 100 ppm, boric acid 0.3%, PGR consortia 1.5%, TNAU Panchagavya 3% and Pink-pigmented facultative methylotrophic bacteria (PPFM) 106 dilution were assigned to sub plot. The results revealed that among fertilizer levels, application 250:125:125 NPK kg ha-1 recorded better yield attributes and higher yield. However, the yield was comparable with 200:100:100 NPK kg ha-1. Regarding the growth substances, PGR consortia 1.5% recorded better yield parameters and yield than the other growth substances.
