Among different production factors, planting methods produce significant effects not only on paddy yield and grain quality of rice but also on soil health and productivity. In present experiment, six planting methods including farmer conventional transplanting, mechanized transplanting, dry direct seeding in lines and broadcasting, dry direct seeding on raised beds by machine and wet direct seeding (broadcasting of pre-germinated seed in puddled soil) were tested to evaluate their response for yield and quality traits as well as cost-benefit ratio. The experiment was planned according to randomized complete block design (RCBD) with four replications and a plot size of 18 m x 27 m. Data were collected on number of plants m-2, plant height, productive panicles m-2, grains per panicle, 1000-grain weight, paddy yield and quality parameters. Economics and cost-benefit ratio of each planting method was also calculated. The results indicated that paddy yield was maximum (5.17 t per ha) in mechanized transplanting but it was statistically at par with Drill-Dry-DSR (4.60 t per ha), broadcasting of soaked seed (4.47 t per ha) in 'wattar' (optimal soil moisture), and Bed-Dry-DSR (4.36 t per ha). Minimum paddy yield was obtained in farmer conventional transplanting (3.68 t per ha). It was further revealed that although transplanting methods produced greater plant height, filled grains per panicle, 1000-grain weight but it was statistically similar to DSR methods except Wet-DSR. Both drilling and broadcasting of DSR were considered to be superior and economical than conventional transplanting.
