Abstract

Field experiments were carried out at Tamil Nadu Agricultural University, Coimbatore, India during samba (August-December) season of 2012 and 2013 to study the effect of different sources of organic manures in comparison with RDF and INM on site specific organic nutrient management practices with different sources of organic manures in comparison with RDF and INM on economics of rice with succeeding greengram during summer 2013 and 2014. The experiment consisted of fourteen treatments which were laid out in Randomized Block Design, replicated thrice and SRI method of planting was adopted during both the years. The gross return per hectare during 2012-2013, extended from 62,971 to 1,14,730 for the rice-greengram cropping sequence. Higher gross return (1,14,730) and net return (68,245) were associated with the INM treatment (T14) with the grain yield of 6235 kg ha-1 and it was corresponded to that observed with T5 viz., 100% RDN through green manure (T5) with the grain yield of 5084 kg ha-1 for gross return (1,12,979) and net return (66,978). During 2013-2014, the gross return and net return of the rice-greengram cropping sequence varied from 63,817 to 1,17,175 and from 32,385 to 70,690 respectively. The INM treatment (T14) recorded with the grain yield of 6270 kg ha-1 and the higher gross return (1,17,175) and net return (70,690) and which was comparable with 100% RDN through green manure (T5) with the grain yield of 5140 kg ha-1 and the gross return of 1,15,380 and the net return of 69,340 respectively. The lowest gross return was registered with the absolute control (T1) (63,817) and net return (32,385) with the grain yield of 3602 and 3646 kg ha-1 during the cropping sequence 2013-2014.
