A field trial was conducted in a randomized complete block design (RCBD) with three replications to evaluate the appropriate planting method of rice variety KSK 282 under field conditions. The trial was planted at farmers field, district Shikarpur during 2010 on silty clay loam textured soil with pH of 7.86, electrical conductivity (EC) 0.40 dSm , organic matter 0.54%, N 0.075% and P 4.2 mg kg . The treatments of the 1 1 experiment were direct seed dibbling, pre germinated seed broadcast,

The results obtained during the study revealed that grain yield and cost benefit ratio of the different planting techniques were in the order line transplantation >, conventional transplantation >, direct seed dibbling >, direct seed drill >, pre germinated seed broadcast. The highest plant height (111.67 cm), productive tillers (337.67 m2), panicle count (330.67 m ), root length (17.12 cm), seed index 2 (27.27 g), straw yield (14.40 t ha ) and cost benefit ratio (1:1.82) were recorded in line transplanting technique. 1 Based on the results obtained, it can be concluded that in areas where labour is available and cheap, line transplanting is a better planting technique of rice because it produces more yield and gross economic return than other methods.
