Abstract: Two years research experiment was conducted during Kharif season of 2014 and 2015 to investigate the, “Effect of methods of tillage, land configuration and sources of nutrients on the performance of direct seeded rice. (Oryza sativa L.)” at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The soil of the experimental plot was medium in available nitrogen, low in available phosphorus and fairly high in available potassium. The field experiment was laid out in split-split plot design comprising 30 treatment combinations replicated thrice. Main plot treatment consisted of three tillage methods, Zero tillage (crop harvest at ground level), Conservation tillage (stubble mulch) and Conventional tillage. The sub plot treatment consisted of Land configuration i.e flat bed and raised bed while, sub-sub plot treatment comprised of five sources of nutrients, Absolute control (no fertilizers), recommended dose of fertilizer (100:50:50 NPK kg ha-1), Konkan Annapoorna Briquettes (56:24:10 NPK Kg ha-1), Konkan Annapoorna Briquettes (56:24:10 NPK Kg ha-1) with soil application of Zinc sulphate @ 25 kg ha-1 and Copper sulphate @ 5 kg ha-1 and Modified Konkan Annapoorna Briquettes(46:20:8:8:1.5N:P:K :Zn:Cu Kg ha-1). In the pooled analysis treatment conventional tillage recorded significantly the highest grain yield than the rest of treatments except conservation tillage which was on par with conventional tillage. Significantly the lowest grain yield was registered under the treatment zero tillage. Treatment flat bed (recorded significantly more grain and straw yield over the treatment raised beds of grain and straw yield in both the years. From the pooled data analysis it was observed that, treatment KAB + soil application of micronutrients recorded significantly the highest grain yield while treatment of absolute control- no fertilizers obtained significantly the lowest grain yield over the rest of sources of nutrients.
