The agricultural zones in the Sonoran Desert have great problems of water availability. An alternative that the grower must consider to diminish the negative effects caused by the water shortage is the establishment of crops with low water requirements. One such crop is the cactus pear vegetable (nopalitos). This crop supports and produces in conditions of low water availability and is a product of high demand. The objective was evaluate the potential of production of nopalitos under this condition. We evaluated two cultivars ( Opuntia inermis  and  O. Ficus-indica ) in a system of furrows with 1 m of separation between lines and 50 cm between plants, with a pruninig system of two producing caldodes per plant. The plot was drip-irrigated every 10–15 days. The evaluation was made during Spring 2004, harvesting the nopalitos to commercial size (17–21 cm) every 3–4 days. The measured variables were the yield and the weight of the nopalitos. The budbreak and harvest of nopalitos appeared in form of productive cycles, and we evaluated only the first two cycles of harvest (24 Mar. to 20 May). The obtained yields were 45.8 and 42 t·ha -1  in cv.  Opuntia inermis  and  O. ficus-indica , respectively. The weight of nopalitos was 112 g and 106 g, respectively. We observed an insect attack (Dactylopiidae), and it was necessary to make two applications of a biological soap for pest control. The presence of this pest was almost exclusively in cv.  Opuntia inermis , producing yellowish color in some cladodes.
