Abstract
In order to enhance the yield of rice by foliar application of organic and inorganic substances, a field experiment was conducted in a Randomized Block Design with three replications at Annamalai University Experimental farm, Annamalai Nagar during Late Kuruvai season (July – September) with CO – 47 rice cultivar. Among the different treatments tried, application of 100% NPK + humic acid granules @ 12.5 kg/ha along with foliar application of Panchagavya @ 3% + Fish meal extract @ 3% + Auxin Gold sea weed extract @ 0.35% on 20, 35 and 50 DAT performed better compared to other treatments and ranked first in terms of plant height, number of productive tillers/m2 (353), number of spikelets /panicle (119), sterility per centage (11.4), grain yield (5.6 t/ha) and straw yield (8.5 t/ha).
