The response of foliar application of bio-stimulants on the growth, yield attributing characters and yield of kharif rice were studied. Application of various types of bio-stimulants such as SeaGrow, triacontanol, humic acid and Panchagavya were foliar applied at different concentrations in comparison to see variation in growth, yield and yield attributing characters of kharif rice. The RDF (100: 50: 50 NPK kg ha^-1) was applied common for all the treatments of the experiment. The application of bio-stimulants showed positive effect on growth, yield and yield attributing characters of kharif rice. Significantly higher values of growth parameters were recorded at 60 DAT, 90 DAT and at harvest with the application of humic acid @ 0.5 per cent. Whereas, significantly maximum grain yield (5036.47 kg ha^-1), straw yield (6155.58 kg ha^-1) and biological yield (11192.05 kg ha^-1) was recorded with the application of humic acid @ 0.5 per cent along with 100 per cent (100: 50: 50 NPK kg ha^-1) RDF. The percent increase in grain yield was to the tune of 27.59 % in T₅ treatment over control (T₇) treatment .
