This the study was conducted for two successive seasons 2014/15 and 2015/16 on a desert soil with the aim to investigate the effect of green manure on infiltration rate and soil moisture retention of desert soil and wheat yield in the Northern State of Sudan as well. Four types of green manure Vigna radiate (Green gram), Vigna sinensis (Cowpea), Dolichos lablab (Lablab bean) and Sesbania canabina (Sesbania pea) were selected as green manure corps with three levels. The first level was a seed rate of 12 kg ha-1, 18 kg ha-1, 24 kg ha-1, 12 kg ha-1 respectively. The second level was two times of the first level and third level was three times of the first level. The treatments were arranged in a randomized complete block design with three replications. The results showed that the effect of green manure was effective in improving the soil physical properties under investigation. The green manure application decreased soil infiltration rate on the average across the two seasons varied from 3.5 cm hr-1 for the control to 1.7 cm hr-1 (105 %) in the green manure treatments except lablab been treatments, and improved the soil moisture retention as well and also, increased available water on the average across both seasons varied form 17 mm in the control to 27.6mm ( 58 %) in the green manure treatments except lablab bean treatments. The result also showed that the effect of green manure obtained very highly significantly (P≤0.001) increase in the grain yield of wheat on the average across the two seasons varied from 0.71 ton ha-1 in the control treatment to 3.21 ton ha-1 (352 %) in the green manure treatments except lablab bean treatments. It is recommended that Green gram (12 kg ha-1), Cowpea (18 kg ha-1) and Sesbania pea (12 kg ha-1) which are available and cheaper are suitable types of green manure crops for soil reclamation of the desert plain soils of Sudan.
