Abstract
In some desert areas where they talk of highly erratic rainfall in millimeters, it has been reported that farmers can produce tree crops by putting rocks around the base of the trees. The rocks cool off at night and collect dew which trickles to the base of the trees. The rainfall situation in South Lombok is definitely much brighter than in the above case. In Sengkol, for example, the lowest annual rainfall was 0.84 meter (1999) and the highest was 2.98 meters (1975) with an average of 1.72 meters during the period 1950 to 2000. Yet, rainfall pattern and distribution seem to be a major factor limiting food crop production in this area. In addition, soils in South Lombok are dominated by Vertisol (Black Earth). High clay contents and swelling-shrinkage characteristic of the vertisols, make them difficult to manage. The soil frequently dries to a massive, cloddy structure that is very difficult to till. This lecture note addresses water and soil management practices of the rainfed areas of South Lombok and points out various options required to increase crop profitability and farming sustainability in these areas.
