Given the negative impacts of the bitterManihot esculenta Crantz varieties on the health ofconsumers and although retting techniques improve thenutritional quality of these bitter varieties, it is necessaryto encourage Manihot esculenta Crantz producers to growalso sweet varieties. This study which set the aim ofknowing how the farmers producing Manihot esculentaCrantz perceive cultivation of sweet varieties in theRepublic of Congo, revealed after investigation in thedepartments of high production of Manihot esculentaCrantz that: 95% of the respondents know the sweetvarieties and 65% know the negative impacts of bittervarieties However, only 20% make the choice ofcultivating sweet varieties compared to 77.5% whichwould prefer bitter varieties. This attitude is justified byseveral major constraints such as the sweet taste thatexposes these varieties to wild animals (24.7%),susceptibility to pests (31.8%), the short cycle that wouldjustify poor conservation in the soil (29.9%). A lowappreciation of products made from sweet cassavavarieties is also worth noting (60%). Indeed, the lack ofproducts resulting from the transformation of sweetcassava into products corresponding to the eating habitsof the populations and the low appreciation of productssuch as “chikwangue” and “foufou” resulting from the transformation of sweet varieties of cassava, limit the cultivation from these sweet varieties to a subsistence andnon-commercial crop.
