Effect of Row Arrangement and Nitrogen Level on the Yield and Yield Components of Transplant Aman Rice

D. Dutta, M.A.R. Sarkar, M.A. Samad and S.K. Paul

Abstract

The experiment was conducted to investigate the effect of row arrangement and nitrogen level on the yield and yield components of transplant aman rice (cv. BRRI dhan 32). The highest plant height at harvest, number of total tillers hill -1, number of effective tillers hill -1 number of non bearing tillers hill -1, grains panicle -1 and total spikelets panicle -1 were obtained in single row arrangement followed by double, triple and haphazard row system. The maximum grain and straw yield were obtained in double row arrangement. The highest number of effective tillers hill -1, grains panicle -1 and grain yield were found where the crop was fertilized with 120 kg N ha -1. These results were statistically identical when 60 and 90 kg N ha -1 were applied. So, cultivation of transplant aman rice (cv. BRRI Dhan 32) in double row arrangement appeared to be beneficial practice and fertilization with 60 kg N ha -1 was more economic in respect of grain yield.
