| Abstract | ||||
| A field experiment was carried-out at the Agriculture Research Station of King Abdulaziz University during 2015/16 and 2016/17 seasons to optimize the productivity of grain sorghum under three irrigation water regimes and three humic acid (HA) levels. The first water regime was received the full irrigation water requirement (100% WR) while the second and the third water regimes received 80% and 60% from the full irrigation water requirements | ||||
