Effect of Different Rice Establishment Methods on Growth, Yield and Different Varieties during Kharif Season
A field experiment was conducted in spit plot design with three replication to “Effect of different rice establishment methods on growth, yield and different varieties during kharif season” was conducted at Agronomy farm, College of Agriculture, Dapoli, Distt. Ratnagiri (M.S.) during kharif season of 2014 on was sandy clay loam in texture, moderately acidic in pH (5.63), medium in organic carbon content (0.82 %), electrical conductivity (Ec) 0.035 dSm-1 , medium in available nitrogen (284.82 kg/ha), low in available phosphorus (14.63 kg/ha) and high in available potassium (248.45 kg/ha). The treatments of the experiment were drilling methods of sowing rice seeds were sown by using manually with 15 cm row spacing as per seed rate (60 kg ha-1). In early transplanting (15 days age old seedling), transplanting as per as recommended (21 days old age seedling) and thomba methods transplanted seedling with 20x15 cm spacing with 3 to 5 seedling per hills. The other common packages of practices were followed time to time and periodically are observations were recorded on growth and yield for evaluate the treatment effects. The results obtained during the study revealed that grain yield of the different establishment methods were in the order, transplanting as per as recommended (21 days old age seedling at par early transplanting (15 days age old seedling)followed bythomba methods transplanted and drilling methods. The highest plant height (71.09 cm), effective tillers (360.58 m2), length of panicle (21.07 cm), test weight (22.24 g), straw yield (47.42 q ha-1), dry matter (1371.92 m-2), weight of per panicle (2.15 g), number of filled grains per panicle (97.08) and B:C ratio (1:2.23) were recorded in line transplanting technique. Based on the results obtained, it can be concluded that in areas where labour is available and cheap, transplanting as per as recommended (21 days old age seedling) is a better establishment methods of rice because it produces more yield and gross monetary economic return than other methods.
