Intercropped fruits are economically valuable fruits of southern Thailand, which include Durian, Rambutan, Rongkong, Champada, etc. Normally several types of fruit are grown. These represent 11.09% (424 farms) of the total rubber growers and can be classified in two patterns of plantations: (1) fruit trees are cultivated in the same plot of rubber, that is, grown between rubber rows, called rubber multi-cropping (Nissapa et al., 1994). The objective is to get fruit production at the same time as rubber production, although farmers tend to postpone the rubber collection if the price of fruit is higher than rubber; and (2) fruit trees are grown in a different section of the rubber plantation. These farmers are normally more experienced and skilled in fruit tree cultivation than farmers in the previous pattern and this pattern is more like a normal business. This type requires higher capital investment and family labor. The constraints of this type include the shortage of water and its management and deficiency of capital investment. However, this type has yielded the highest economic performance due to greater farm income than other farm types.
