The present investigation was undertaken during Kharif 2011 at University of Agricultural Sciences, Dharwad to know the response of organic nutrient management practices on yield and nutrient uptake of aerobic rice. The experiment was laid out in Split Plot Design with 2 main plot treatments, 8 sub plot treatments and 2 controls. The main plot treatments comprised of M1-EC (1/3)+VC (1/3)+GLM (1/3) equivalent RDNand M2-EC (1/3)+VC (1/3)+GLM (1/3) equivalent to RDF + FYM, sub plot treatment comprised of L1-bio-digester @ 500 l ha-1 applied at planting, 30 and 60 DAS applied to soil, L2-jeevamrut @ 500 l ha-1 applied at planting, 30 and 60 DAS applied to soil, L3-Panchagavya @ 5 per cent foliar application at panicle emergence and flowering stages, L4-cow urine @ 10 per cent foliar application at panicle emergence and flowering stages, L5-L1+ Panchagavya @ 5 per cent foliar application at panicle emergence and flowering stages, L6-L1+ cow urine @ 10 per cent foliar application at panicle emergence and flowering stages, L7-L2+Panchagavya spray @ 5 per cent at panicle emergence and flowering stages and L8-L2 + cow urine @ 10 per cent foliar application at panicle emergence and flowering stages and two controls were RDF only and RDF + FYM. Application of different organic manures significantly increased the yield and nutrient uptake of aerobic rice. The Results revealed that integrated application of M2- EC (1/3)+VC (1/3)+GLM (1/3) equivalent to RDF+FYM with soil application of jeevamrut @ 500 l ha-1 at planting, 30 and 60 DAS+Panchagavya foliar application @ 5 per cent at panicle emergence and flowering stages recorded significantly higher grain yield (3837 kg ha-1) and straw yield (5855 kg ha-1) with higher nutrients uptake.

Application of different organic manures significantly increased the yield and nutrient uptake of aerobic rice. The Results revealed that integrated application of M2- EC (1/3)+VC (1/3)+GLM (1/3) equivalent to RDF+FYM with soil application of jeevamrut @ 500 l ha-1 at planting, 30 and 60 DAS+Panchagavya foliar application @ 5 per cent at panicle emergence and flowering stages recorded significantly higher grain yield (3837 kg ha-1) and straw yield (5855 kg ha-1) with higher nutrients uptake.
