Abstract
This study was conducted to evaluate effects of planting densities ($60{\times}10cm$, $60{\times}15cm$, $60{\times}20cm$) and PE mulching (polyethylene film mulching, non-mulching) on growth and yield of proso millet in drained paddy field for 2 years. In PE plots, culm length, culm diameter and fresh weight were higher than non-mulching plot. Additionally, spike length and seed weight per hill were also higher in PE plot but thousand seed weight was weightier in non-mulching plot. The yield of proso millet were increased with 10.0% and 15.5% at PE plot in 1st and 2nd, respectively. Culm diameter was thickest at $60{\times}20cm$ plot with 8.43 mm in 2nd however, culm length was longest at $60{\times}10cm$ plot with 130, 142 cm in 1st and 2nd, respectively. Plant height was higher by the increase of planting density. As plant density decreased, that spike length and seed weight per hill were increased. Yield of planting density were highest at $60{\times}15cm$ plot $265kg{\cdot}h10a^{-1}$, $253kg{\cdot}10a^{-1}$ yearly, respectively that it were in order of $60{\times}15cm$ plot > $60{\times}10cm$ plot > $60{\times}20cm$ plot.
