Abstract: A field experiment was conducted in Agricultural College Farm, University of Agricultural Sciences, Raichur, Karnataka during Kharif- 2017, to study the influence of organic foliar nutrition on growth and yield of sunflower,- hybrid KBSH-44. The experiment was laid out in a randomized complete block design with twelve treatments and was replicated thrice. The sources for organic nutrition were Vermicompost extract (1:10), FYM extract (1:10), Neem cake extract (1:10), Cow dung extract (1:10), Pongamia cake extract (1:10), Panchagavya @ 3%, Jeevamruta @ 3%, Panchamruta @ 3%, Humic acid @ 4ppm and were compared with in organic Boron @ 0.1%, Water spray and Control. Among the organic nutrients spray treatments, the significant increase in the seed yield was observed with Panchagavya @ 3% followed by Jeevamruta @ 3% and it may be attributed to the improvement in the morphological and yield traits viz;, plant height, number of leaves, total dry matter accumulation, leaf area, head diameter, achene filling percentage, test weight and seed yield per plant. However, Boron @ 0.1% recorded numerically higher yield over Panchagavya @ 3% spray.
