Irrigation frequency affects soil properties with a residual influence on soil moisture potential, crop performance and shoot yield of vegetables. This study investigated the effect of irrigation frequency on the growth, shoot yield of large green, soil moisture potential, and soil chemical properties based on ramdomised complete block design experimental procedures with three replicates. The response of growth parameters, dry matter production and leaf area to irrigation frequency were found to be significantly best for watering trice per week (P<0.05). Soil moisture potential (SMP) was lowest (-10cb) in three irrigation frequencies (W3) per week and one irrigation frequency (W1) per week had the highest mean value of (-37cb) SMP. Mean diurnal soil temperature varied between 31.60 C and 25.70 C for watering once every Week (Wi). Soil temperature was progressively lowered with increasing irrigation frequencies, although there were no significant differences (p<0.05) for three irrigation frequencies per week than the other two treatment. Therefore, irrigation frequency of there application per week was found optimal for the production of large green during the dry season.
