Farmers’ knowledge and perception of postharvest physiological deterioration in cassava storage roots in Ghana

Background In spite of the essential role of cassava in ensuring household food security and employment for most rural farm households, postharvest physiological deterioration (PPD) of the roots which is serious abiotic stress in cassava renders the roots unmarketable, thereby reducing the economic value of the crop. This paper investigates farmers’ knowledge and perception of PPD in the storage roots of cassava among smallholders in Ghana.
