2 .New Rice for Africa (NERICA) variety is a generic name used for rice varieties developed from the interspecific crosses between Asian rice (Oryza sativa) and African rice (O. glaberrima) by AfricaRice. NERICAs are high yielding and are resistant to indigenous biotic and abiotic stresses. Where piloted New Rice for Africa is a cultivar group of interspecific hybrid rice developed by the Africa Rice Center to improve the yield of African rice cultivars. Although 240 million people in West Africa rely on rice as the primary source of food energy and protein in their diet, the majority of this rice is imported. Self-sufficiency in rice production would improve food security and aid economic development in West Africa. The results of the NERICA Project, which is funded by the In this study 22 upland rice genotypes of different origins, most from Africa (all 18 upland NERICA, N1-N18); Japan (3) and Mynmar (1) were used in the experiment. The genotypes and their sources of origin are contained in table 1. The experiment was conducted in Yoga experimental station (Tokyo University of Agriculture). The experiment NERICA combines the high-yield properties of Asian rice with the resilience of African rice, which is known for resistance to drought and disease. The experiment tested mechanisms that could encourage farmers to try NERICA, such as subsidies to purchase seed, training in new cultivation methods, and information about how its adoption might affect agricultural and health outcomes. associated factors. The results revealed that NERICA adoption rate was barely 40% falling far below the expected 83%. The shortfall was due to the incomplete stakeholder exposure to NERICA in the period before 2006. The introduction of NERICA to villages was found to be a significant determinant of both exposure and adoption of NERICA varieties.
