In order to assess the value for dryland cropping in a semi-arid region of concentrating rainfall by means of micro-watersheds, a study was established with width of micro-watershed, width of growing bed, plant population, and applied level of nitrogen fertilizer as variables. Due to very low rainfall, little water was available for concentration and yields of winter wheat and winter barley were very low and were decreased with increasing amount of watershed area (proportionately less of area planted). A study on use of herbicides indicates propazine and atrazine applied on the watershed areas may control weeds without injury to crops. It was concluded that the first year results of the study were atypical because of extreme drought and that several years data will be necessary in order to sample various amounts and patterns of annual rainfall and to determine the cumulative effects.
