Abstract
Potato experiments were carried out in Saltillo, Coahuila (North of Mexico) in the springs of 1991 and 1992. Different mineral and carbonic nutrition treatments were applied in the drip irrigation system. All plots received the same amount of irrigation, based on the water evaporation and the coefficient of development (Kc) . The daily CO2 supply was correlated to total leaf area and ratio of mineral nutrients change with the crop develop. The concentration of CO2 in the air was constant during day time (350–450 ppm) and leaf photosynthesis was increased. In experimental plots of 1992 additional sulphur nutrition and chemical regulator (MC1) were supplied to promote diameter of stem and were of great influence on the yield of potato, and resulted in a more stable response to CO2/H2CO2 enriched water.
