Abstract
Field experiments were conducted at Agricultural Research Station, Thirupathisaram, Tamil
Nadu during kharif and rabi of 2011-12 to study the different establishment techniques on
growth and yield of rice. The experiment was laid out in a randomized block design with four
replications. The treatment structure comprises of wet seeding, drum seeding, random
transplanting, line planting, SRI square planting and SRI machine planting. Among the different
crop establishment techniques, SRI machine planting significantly influenced the growth and
yield characters and yield and was on par with SRI square planting. The maximum plant
height, number of tillers, number of panicles/m2 , number of grains/panicle, panicle length,
grain yield, straw yield, gross return, net returns and BC ratio were recorded under SRI
machine planting during kharif and rabi. The lowest grain yield, straw yield, gross return, net
returns and BC ratio were recorded under wet seeding during both kharif and rabi.
