Abstract

In pot trials sorghum cv. H-726 was irrigated when soil pF reached 1.5, 2.0, 2.5 or 2.8 beginning at the 4-leaf stage, or was subjected to drought periods of 4-36 days or to wilting, successive wilting when no recovery occurred at night, or further periods of 3 or 6 days without water. Successive wilting or severe moisture stress decreased growth, grain yield, fodder yield and grain protein content but not grain starch content. Water stress at heading retarded peduncle elongation while stress at early grain filling decreased panicle wt., grain number and dry wt./panicle and 1000-grain wt. Moderate water deficit tended to produce more elongated roots. Drought for 10 days at the vegetative stage increased growth and yield if wilting did not take place
