Abstract: Sorghum is an important staple food for feeding humans and animals in sub-Saharan African country. Nowadays, with the advent of climate change coupled to the population growth, the crop is faced with new challenges which are gradually affecting the productivity. In Niger, a dry land country where farmers are growing sorghum at a small scale for family subsistence, the crop is confronted to biotic and abiotic constraints including nutrient deficiency in the soil. Among those constraints, Striga is the one that causes huge damage to sorghum cultivation through yield reduction. In addition, nutrient depletion in the soil is causing weed progresses in farmer’s field at a large scale. In fact, to overcome Striga problem several control methods have been successfully tested, but some of them are efficient but not accessible to farmers. It is important to control the weed by using effective and accessible way for smallholder farmers in Niger. The main objective of this study was to assess the effectiveness of different doses of sesame (0, 0.5 and 1.5 g) and DAP (0, 2 and 5 g) on Striga impact and sorghum grain yield. Two (2) grammes micro dosing utilization of DAP shows good result in Striga plant emergency and distribution along sorghum field. Concerning the three doses of sesame seed involved in this experiment, the micro dosing two (1.5 g) positively affects Striga effect. The combination of sesame seed and DAP can significantly reduce Striga impact on sorghum cultivation and increase sorghum grain yield.
