In case of farmer’s coping adaptation strategies, some farmers decided to grow cassava
replacing rice before maturity when they observed that rice will produced low yield. However,
some farmers waited until rice reach to maturity growth stage. Then, cassava will be planted soon
after rice harvest in post-rainy season. Cassava started their growth using residual soil moisture
remaining in the soil and with supplement summer rainfall and pre-rainy of consequence year
during the growing season. In a recent study, cassava experienced to drought during the third week
of March to the third week of May. Since the cassava crop receive rainfall once the last week of
January (16 mm) and the first week of March (27 mm), and prolong drought until the third week of
May. Then, cassava crop received accumulate rainfall about 80 mm until harvest. Cassava is
regarded as a relatively drought resistant crop (Cock, 1985). During drought, it reduces water use
by following an avoidance strategy of stomatal closure (Ike, 1982) and leaf area reduction (Connor
and Cock, 1981)
