The effects of three irrigation treatments once per week of (6mm), twice per week (12mm) and thrice per week (18mm) on okra were investigated between October 1995 to March 1996. Irrigation was based on the previous measured field capacity.
Soil moisture potential deceased with frequency of irrigation while the soil temperature at deceased 5cm depth decreased with increasing frequency of irrigation. However, frequent irrigation resulted in increased surface run off and soil loss.
Fresh fruit yield of okra increased proportionately with increasing frequency of irrigation.
This study suggests that to minimize soil moisture depletion and preserve the soil structural stability, irrigation for okra production could be limited to twice per week at 12mm of water wk-1.
