This paper describes the evaluation of the irrigation efficiency of a low-cost, low-head drip irrigation system in the Dry Zone of Sri Lanka. The Institute of Hydrology set up field trails in which soil moisture regime and plant growth of four vegetable crops irrigated using the drip system were monitored and compared with controls irrigated by conventional furrow methods. This paper discusses the analysis for two of the crops: chilli (Capsicum annuum) and onion (Allium cepa). Although irrigation efficiencies were much greater for the drip irrigated crops, some yield reduction was noted. Recommendations are made that will lead to greater water savings and, possibly, higher yields under drip irrigation.

The distribution of soil moisture potential around emitters spaced 0.75 m apart along driplines buried beneath a crop of sugar cane was monitored throughout the growing season using arrays of mercury manometer tensiometers. The amount of irrigation to apply was determined using estimates of potential evaporation, and effective rainfall model, and crop factors. The potential measurements showed that a wet zone, bounded laterally by steep potential gradients, persisted below the emitter throughout the 5 month period studied. The size and form of the wet zone, or "wetted volume" varied diurnally and through the study period as a result of the sensitive dynamic equilibrium between irrigation, abstraction and drainage. The long term variations in size occurred when irrigation inputs did not exactly match the abstraction by the crop. The results indicate that abstraction by the crop must be taken a pre-determined proportion of the soil profile.
