Proper management and use of resources is well necessary to obtain sustainable and economic results especially
in marginal land areas like arid lands of Saudi Arabia. To attain the above mention feathers a field experiment
was carried out at the Agriculture Research Station of King Abdulaziz University to evaluate the comparative
effect of humic acid application methods and rates on seed yield and yield components of mungbean and some
soil micronutrients in arid region of Saudi Arabia. A two factor factorial under randomized complete block
design was used in this experiment with four replications. Two methods of humic acid application (solid vs
liquid) and Three treatments of humic acid (HA 20, 20kg/ha; HA 40, 40kg/ha and HA 60, 60kg/ha) along with
control (HA 0) were applied. Results indicate that application of humic acid in solid form resulted in significant
improvement in yield and yield components (shoot fresh weight, shoot dry weight, root fresh weight, root dry
weight, hundred seed weight and seed yield). Regarding rates, increasing HA ratesincreased all yield and yield
components. Significant increase in all yield components was observed at first three levels of humic acid rates
(HA 0 kgha-1 To HA 40 kgha-1), while increasing humic acid rate from (40 to 60 kgha-1) all yield and yield
components were statistically similar except seed yield. It is concluded that interaction of solid application
method with increasing rates of humic acid upgraded yield and yield component of mungbean and enhance the
micronutrients (Cu, Zn and Mn) status in soil solution under arid land region of Saudi Arabia.
