Effect of planting methods and varieties on growth and yield of paddy under rainfed conditions

Abstract

A field experiment was carried out using split plot design with three replications during Kharif 2017 to evaluate the effect of planting methods and varieties on growth and yield of paddy under rainfed conditions. The study comprised of five planting methods as main plots and two varieties as sub plots replicated thrice. Significantly superior plant height, number of effective tillers plant-1, number of panicles plant-1 and number of grains panicle-1 were observed with PKV SRI method transplanted at 25 cm x 25 cm over rest of the treatments. While drilling at 20 cm and farmers practice were at par with respect to all yield attributes and yield of paddy. Plant height, number of effective tillers plant-1, number of panicles plant-1 and number of grains panicle-1 were not influenced due to varieties. Maximum grain yield (27.96 q ha-1) and straw yield (42.93 q ha-1) were obtained with the method of PKV SRI transplanting at 25 cm x 25 cm which was significantly superior over other methods. The PKV SRI transplanting at 20 cm x 20 cm was found to be at par with drilling at 25 cm; drilling at 20 cm and farmers practice.
