محدود کردن انقلاب سبز برنج در آفریقا: مورد غنا

Employing yield response models and profitability analysis, results show various practices contribute to yield improvements in irrigated and rainfed systems in 10 regions in Ghana. Evidence also shows that extension services on rice production are limited and that intensifying these services can contribute to increases in rice yield. While some technologies can contribute to increasing yields, marginal increases in yield from these technologies in rainfed systems are not high enough to match the productivity growth achieved during the Green Revolution in Asia. Expansion of irrigated areas, coupled with market infrastructure, will be necessary to boost rice productivity and production in Ghana.
