Abstract:

In Israel the major limiting factor to allow profitable agricultural activities is lack of water. Dry land production is unfeasible due to the fact that the agricultural sector in Israel is in the upper middle class. Hence, without irrigation water, agricultural production will not meet the expected stability, production, and income for the agricultural sector. Some plant physiologists claim that there are no plants with real high water use efficiency, since when stomata are closed, reduction in CO2 uptake diminishes production. These scientists never considered CAM plants as crops due to the fact that they almost non-existent in the so called “developed world.” With the aim of using CAM plants as crops with high water use efficiency (WUE) we started, 2 decades ago, to research various biological aspects of the vine cacti—red and yellow pitayas (Cactaceae) mainly species of Hylocereus and Selenicereus. Fortunately, 3 of these species became established fruit crops in Israel both for the domestic and export markets. Since these new crops utilize the CAM photosynthetic pathway, we asked the question whether expectations were fulfilled: are they really high WUE crops and if yes, to what extent? To answer these questions we conducted a 3 year research project with 3 of these new crops, applying various water regimes and tested both the yields and the fruit quality concomitant with other water regime parameters. The 3 water regimes we used were: the standard used in the area, one with less, and one with more water. We compared the agricultural WUE of these new crops with other common fruit crops grown in the same vicinity, i.e., how much water is used for production of one tonne of fruit?
