90 leaves For the purpose of understanding the existing farming systems being practiced in the rainfed lowland rice area, this study was undertaken in Battambang district, one of the well-recognized district in rice producing in Battambang province of Cambodia. The study examined the local operational environment by investigation the implications of all relevant factors such as physical, biological, resource, and socio-economic that prevailed in the current agricultural production. Furthermore, the study also tried to find out the economic viability and the incomes derived from each farming enterprise within the current farming system. Annual family income from both farming and non/off-farm activities was explored. The study revealed that the existing farming system is the integrated system of crops, dominantly rice, with livestock, vegetable and fruit tree on the area surrounding the house, following mostly traditional farming. The degree of intensification and diversification in farming is still low. Crops yield are low. The average wet and dry season rice yield is 1.5 t/ha and 3.0 t/ha with almost the same return above variable cost of 1.5. Sweet potato gives the highest retUl'n to variable cost (3.6), next followed by maize (2.9). Chicken raising provided higher net return and return above variable cost (1.2 $/head, and 2.2) than pig and duck rearing. Cattle are mainly raised for draft power, while some cow are reared for stock as well as draft. Livestock production provided low yield due to poor breeds with long period of production and epidemic diseases prevailing. Vegetable and fruit tree are grown primarily for home consumption and only the surplus are sold for family income. Non/off-farm income is earned mostly from off-farm work in agriculture during the wet season with the annual average of $ 166.0. The study area was ease to access to the central provincial and district market and good security. The prices of agricultural products are fairly reasonable. The most relevant constraints which hinder the fai·mers from more diversified and intensified farming are: lack of water supply for home use as well as irrigation, lack of institutional supports especially government supports in agricultural extension, lack of cash and low family income, natural calamities, uneven farm size holding, poor soil fe1tility.
