The field experiment was carried out using split plot design with four replications during kharif 2009 and 2010 to investigate the effect of varieties, depth and planting methods on growth attributes, yield and economics of rice. The experiment consisted three level of varieties (V1- Sugandha-3, V2- JRH-5, V3- Pro-Agro-6444), two levels of depth (D1- 2.5, D2- 5.0 cm) in main plot and two level of planting methods (M1-SRI, M2-DSSS) arranged in sub-plot. Among the different tested varieties, V3- Pro-Agro 6444 produced significantly length of panicle, healthy grain panicle-1 (146.89 and 147.15), 1000- grain weight (29.25 and 29.59) and production efficiency (51.67 and 53.27) produced highest grain yield (72.86 and 75.11 qha-1) than other varieties, respectively during both the years. Significantly higher value of length of panicle, healthy grain panicle-1, 1000- grain weight, production efficiency and grain yield were recorded under transplanting at D1- 2.5 cm than D2- 5.0 cm. Further, SRI system (M1) was find higher yield attributing characters and finally produced maximum grain yield. Based on the result variety V1 at shallow depth of 2.5 cm under SRI system was produced highest grain yield and economically the highest B: C ration were in V3(2.17), D1(1.80) and M1(1.76) by gaining highest net return during both years.
