Abstract : Kingdom of Saudi Arabia is a country with tremendous land resources but also with limited water resources. Moreover Most of its cultivated soils are sandy soils characterized by low water holding capacities, high evaporation and infiltration rates, deep percolation losses which resulted in low water use efficiency and low fertility levels. Therefore, this research was conducted to optimize mungbean crop production, water use efficiency and soil fertility by figuring out the best-integrated combination among irrigation timing, levels and methods of humic acid application. The findings could be consider a partial practical solution to the above-mentioned problems of sandy soils. To fulfill the above objectives field experiment in split-split design with four replications was conducted at the Agricultural Experimental Research Station located at Hada Al-Sham, King Abdul-Aziz University during two consecutive seasons of 2015-2016 and 2016-2017. It is concluded that, application of humic acid in solid form at the rate of 40 kg ha-1 along with night irrigation timing (N-T) proved to be better option for optimum and economic yield as well as for soil fertility and productivity under the arid region of Saudi Arabia. Its application also caused reduction in bulk density of soil. Application of humic acid in solid form at the rate of 60 kg ha-1 along with night time irrigation also resulted in yield induction, improvement of soil properties and water use efficiency but found statistically similar to 40 Kgha-1. Application of humic acid at 20 kg ha-1 with both solid and liquid methods with day time irrigation (D-T) found statistically similar for yield and yield components and soil chemico-physical properties with control (NPK only). Irrigation during day-night time (DN-T) was the least production among all irrigation timings.
