    Abstract: The high cost of inputs and water deficit in arid lands demand the use of more drought tolerant species into the agricultue. The flora of the deserts offer a variety of fruits and vegetables that may diversify horticulture. `Cimarrón' wild plum tree or “ciruelo cimarrón” ( Cyrtocarpa edulis Brand.:Anacardiaceae) is one of the species with potential importance in arid lands. C. edulis is an endemic tree of the meridional portion of the Baja California peninsula, occurring along arroyos and on gentle slopes in sandy soils. The flesh of the fruits is edible, with a slight acid tang, and is used locally. Actual exploitation is based on the fruit harvest in natural dry forest and xerophilous shrubs, where average density is near 100 trees/Ha. There is a growing interest in marketing the dried fruits, especially for the snack industry, hence, the need to develop a breeding program in order to establish it as a reliable fruit crop.

    Abstract: Cherry tomatoes growth, water demand and yield were measured under different water quality conditions in order to assess their performance in arid and saline soils. Treatments were: i) desalted seawater and humid conditions, ii) fresh water and dry conditions, and iii) saline water and humid conditions. No fertilizers were added. Differences highly significant were found in all treatments. The highest yield (6 Kg/plant) was observed in the plots irrigated with desalted seawater, and the lowest (0.4 Kg/plant) in the plots irrigated with saline water. Water demand and some hydric parameters were higher in the salt affected soils. Fruit size was similar in all trealments. The results suggest that the establishment of cherry tomatoes in saline non-productive soils is feasible, as an alternative to other varieties.

    Abstract: Water scarcity delay the social development in the coastal arid zones of México. In these areas, fresh water can be obtained from the ocean using different methods. In this work, a design of a self-sufficient system for desalting seawater, using the sun and the wind, is applied to irrigate a small horticultural plot. A daily mean water production of 160 l was obtained from a 60 m 2 solar desalter, which was supplied with seawater with an aeolian pump. Three varieties of tomatoe were assayed: ACE-55, Cherry, and Saladette. Cherry tomatoe showed the highest yield with a consumption of 45 l/plant per month. A plastic mulch was used to minimize evaporation. The system may represent an economic alternative with low-maintenance requirements for self-supplying vegetables in marginal coastal zones.

    Abstract: Diurnal and seasonal water relations, soil humidity, transpiration, water demand, stomatal resistance, and fruit production, as well as some microclimatic parameters, were studied in a semidomesticated chile ecotype ( Capsicum frutescens ) under two treatments of plastic mulches, black and opaque, and compared with plants without a mulch in Baja California Sur, a Mexican semiarid state. Plants with opaque plastic mulch showed the highest chile production and total growth. The biggest transpiration rates from January to April was evidenced also by this treatment. The soil water content seemed to be determinant. Opaque plastic mulch plants had more soil moisture during the whole experiment. Plants without plastic mulch had the least chile production, with a lesser soil water content. These plants evidenced an osmotic adjustment under drought stress with low water potential, maintaining a partial turgor pressure, and stomatal regulation, in order to control the lost of water by transpiration.

    Abstract: Mango ( Mangifera indica L. ) has been grown since the beginning of the century in Baja California Sur, one of the most arid states of México. Since water is a very scarce resource in this area, the estimation of water consumption by popular crops becomes a relevant aspect of hydrological research. Actual (ET a ) and potential (ET p ) evapotranspiration of mango c.v. Kent were estimated in the Experimental Station of CIB, located 17 Km west La Paz city. Trees under study were three years old; irrigation frequency was 14 days and depth of applied water was 0.15 m, a common amount in the region. Estimates for ET p were carried out through two indirect methods (Blaney-Criddle and Penman equations), and ET a by a direct method (a diffusive porometer). Data were fitted according to the total leaf area (TLA). Estimates from the indirect methods were 31 and 25% respectively greater than those given by the porometer. Main results (ET a = 0.5 cm day -1 , or 0.07 m H 2 0/14 days) suggest that a 40 to 50% reduction in the applied water depth is feasible in the region.
