  The effects of climate change on North Kordofan state ecosystems are severe, widespread and affect food security as well as productivity; hence in the latest years the state characterized by limited rain fall situations. Therefore, efficient use of microdosing fertilizers seems to be of vital importance to enhance productivity of the rain-fed crops cultivated in the area. The present research was conducted during two successive rainy seasons (2014/15 - 2015/16) at two locations. The research was carried out to investigate the effect of micro- dose of NPK with control treatments on yield of pearl millet (Pennisetum glaucum) and cowpea (Vigna unguiculata). The study concerned with pearl millet yield attributes such as: number of tillers per plant, tillers weight (g), 1000-grain weight (g) and yield (ton/ha). In case of cowpea the attributes include: number of pods per plant, number of seeds per pod, 100-seeds weight (g) and seed yield (ton/ha). The experiment was laid out in a Randomized Complete Block Design (RCBD) with six replications. Data were analyzed using (ANOVA). In pearl millet, micro dose was significantly higher than control in number of tillers per plant and tillers weight found to be 24.12g in case of dose application and 17.80g in control. The results showed highly significant effect of micro-dose in pearl millet yield (p ≤ 0.05), high micro dose recorded 3.30 ton/ha, while the control recorded 2.17 ton/ha. On the other hand cowpea produced the highest number of pod per plant under micro-dose (24.06) and (17.61) with control. The highest number of seeds per pod was demonstrated by micro-dose treatments which resulted in increased final seed yield of 2.65 ton/ha as compare to control 1.69 ton/ha. It was concluded that application of micro-dose of NPK had a significant effect in most studied attributes and shortening the maturity period. Therefore, to increase yield and yield components in the study area during rainy seasons application of micro-dose of NPK is recommended.
