This study was conducted to evaluate effect of plants number per hill (PNH) on growth and yield of sorghum in drained paddy field for 2 years. Crop growth and development and yield in the field was examined to know the efficiency of proposed cropping system. At seeding after 40 days, leaf number and stem diameter were highest at 1 PNH plot, on the other hands, plant height was at 5 PNH plot the 1st and 2nd, respectively. The harvest stage, 5 PNH plot was highest culm length of 183, 188 cm the 1st and 2nd, however, culm diameter was lowest. Culm length of sorghum was highest by 183, 188 cm at 5 PNH plot also, culm diameter was thickest by 19.18, 20.13 mm at 1 PNH, respectively. Yield components of ear length, seed number per ear and 1000-seed weight were highest at 1 PNH the 1st and 2nd, respectively. As yield of sorghum was highest at 2 PNH plot 344 kg․10a-1, 382 kg․10a-1 yearly, respectively that it were in order of 1 PNH plot > 3 PNH plot > 4 PNH plot > 5 PNH plot.
