A field experiment was conducted during kharif season in 2012-2013 at Agricultural Research Farm, Institute of Agricultural Sciences, BHU-Varanasi, to study the effect of varying seed rates and row spacing on growth, yield attributes and yield of aerobic rice. The experimental results revealed seed rate @ 35kg/ha recorded significantly highest growth parameters viz. plant height, number of tillers, number of leaves and dry matter accumulation at all the growth stages of rice. Significantly highest number of panicles/m2 and yields (grain and straw yield) were also recorded with seed rate of 35 kg/ha. Row spacing of 20 cm recorded significantly highest growth parameters, number of panicles/ m2 and yields were obtained which was found to be statistically at par with row spacing of 25 cm.
