Aerobic rice system is the method of cultivation, where the rice crop is established by direct seeding in un-puddle field. The grain yield of aerobic rice in aerobic situation realized by the farmers is still lower. Among many factors, seed rate and row spacing influence the grain yield of aerobic rice crop. The present investigation was carried
out to study the influence of seed rates and row spacing on grain yield of aerobic rice in aerobic situation, and field experiment was conducted at Rice Research Station, Bankura, West Bengal, India during kharif season of 2011 and 2012. The experimental results exhibited that the highest grain yield (3.40, 3.49 and 3.42 t ha-1 during kharif 2011, kharif 2012 and in pooled value, respectively) was recorded from treatment S2, where seed rate was 30 kg ha-1. Among the different row spacing, the maximum grain yield of 3.47, 3.45 and 3.46 t ha-1 during kharif season of 2011 and 2012 and on pooled basis was obtained with the treatment R1 i.e. 20 cm row spacing. The treatment combination of S2 (seed rate @ 30 kg ha-1) and R1 (20 cm row spacing) recorded the highest grain yield (4.01 t ha-1) of aerobic rice. It was established that the seed rate @ 30 kg ha-1 and 20 cm row spacing was promising for realizing best grain yield of aerobic rice in aerobic condition. It is an important eco-safety tool for tackling the climate change scenario.
