In the western region of Daloa, producing a quarter of Ivory Coast's output, the average price fell five CFA francs per kg to 350. Farmer Attoungbre Kouame said some growers there who had chosen not to sell in the hope prices would rise were finally parting with their beans.
"A lot of farmers who were reluctant to sell because they said prices were too low are now starting to sell," he said.
"They're very disappointed about the price, which varies between 300 and 325 CFA here, but they don't know what else to do so they have to sell the beans," he added.
Exporters and buyers said on Monday they were concerned more growers would hold back beans if farmgate prices continued to fall in line with world prices, which are sliding because of healthy crop forecasts and relative calm in Ivory Coast.
London cocoa closed at a six-week low on Monday and farmgate prices, which usually fluctuate to some degree in line with world prices, are likely to fall further if the downward trend continues.
In the southern town of Agboville, the average price rose by 15 CFA francs per kg to 340 during the period as increasing numbers of buyers in the region generated competition for beans.
