摘要：This paper examines the economic analysis of the production of two cabbage varieties, KK-Cross and Oxylus, grown under water application levels of 100%, 85%, 70%, 55% and 40% of the required water using a small-scale drip-irrigation system. Marketable yield data for drip-irrigatedKK-Cross and Oxylus were obtained from on-stationfield experiments, farm gate price of cabbage was obtained from farmers whilst input cost associated with the installation of small-scale drip-irrigation system were estimated. Analyses showed that the KK-Cross cabbage variety has higher Net Present Values (NPVs) than Oxylus at all the different water application levels except at the 55%. The Benefit-Cost-Ratios (BCRs) were also lower for Oxylus than KK-Cross thereby making the production of KK-Cross economically viable. Results further indicate that the mean paired comparison t-test of the cumulative BCRs were statistically different (P¡Ü0.05). However, paired comparison t-test analysis showed no significant difference (P>0.05) between NPVs of KK-Cross and Oxylus production. Farmers are therefore likely toreap higher economic returns from the cultivation of KK-Cross than Oxylus. It is however recommended that production of KK-Cross and Oxylus should not be done at 40% level of applied water as BCR values at that water application level were close to 1.0.
