J. M. DE FORGES: Research on the Utilization of saline water for irrigation in Tunisia. Nature and Resources, Vol. VI, No. l, 1970. Unesco, Paris. The Research Centre for the Utilization of Saline Water for Irrigation (CRUESI) has recently completed its seven-year U N D P programme on the utilization of saline water for irrigation in Tunisia. The mean average salinity of the water used in various areas and with the crops studied ranged from 0.2 to 6 g/1 under annual rainfalls ranging from 90 to 420 ram. The crops investigated included artichokes, alfalfa, beans, water-melons, Sudan grass, maize and tomatoes. The yield of artichokes, for example, was maintained at 100 per cent with salinities up to 4 g/l, and the yield of tomatoes fell to 50 per cent with a salinity of slightly less than 3 g/l. CRUESI's activities showed that if the advice given in the published pamphlets is followed, crops can be raised with the saline waters considered, but with a calculable decrease in production. F.D.
