Abstract: The effect of row arrangement, time of tiller separation and number of tillers kept hill -1 was investigated on growth of transplant aman rice (cv. BR23). The experiment comprised of three row arrangements viz., single, double and triple row; two times of tiller separation viz., 25 days after transplanting (DAT) and 35 DAT ; and three levels of number of tillers kept hill -1 viz., 2,4 and intact hills. The tallest plant and the highest number of tillers hill -1 were recorded in single row, intact hills and when tiller separation was done at 25 DAT. On the other hand the highest leaf area index and total dry matter were recorded in triple row and intact hills. Growing of transplant aman rice in triple rows with intact hills appears as the promising practice in respect of highest leaf area index and total dry matter production. In single row tillers can be separated at 25 DAT without hampering plant height and tiller production hill -1.
