INTRODUCTION TO THE SWEETPOTATO ICM FARMER FIELD SCHOOL |
|
|
Sweetpotato cultivation can be highly profitable for farmers. When market prices are high, farmers' profits double or triple compared to those from growing rice. The relatively high yield and low production costs contribute to this profitability, but unfortunately, in many places in the world sweetpotato prices fluctuate widely. Sometimes, when price declines radically, sweetpotato farmers might have lose money. The marketing system may also limit farmers' profits, particularly when middlemen are involved who make contracts with farmers to buy the standing crop. Because farmers rarely know how to estimate the yield of the unharvested crop and are not fully aware of the prevailing prices at wider distribution markets, they are at a disadvantage in price negotiations with the trader and usually accept the offer with little discussion. Most farmers believe that profit is determined more by their luck in making a sale agreement with the trader than by the yield of the crop. |

Highly fluctuating prices and a weak bargaining position influences farmers’ attitudes towards sweetpotato cultivation because it provides little incentive to produce high yields. Nevertheless, comparison of yields and profits obtained by farmers in Indonesia showed a tendency for farmers who produced higher yields to earn higher profits. This suggests that farmers can increase profits by increasing their yields through better crop management, and by learning to estimate what the yield is likely to be before entering into negotiations with a trader. How can farmers’ knowledge and skills be developed so that they can improve their crop management and business capacities? In this activity, farmers will analyze the relative importance of the sweetpotato enterprise and its constraints. ICM is presented as an alternative to tackle the constraints, and the FFS as a way to learn about ICM. |
