Abstract: Additional index words. drip irrigation, Cucumis sativus, Lycopersicon esculentumMauney and Hendrix (1988) reported that CO 2 -saturated irrigation water increased P, Mn, and Zn uptake and vegetative growth and boll count in cotton.Nakayama and Bucks (1980) found that delivering CO 2 -amended water through a drip irrigation system increased wheat yields.Based on these and other reports (D'Orazio, 1990), California and Arizona growers have begun to adopt this technique in the field on a variety of crops.This study was conducted to determine the effects of CO 2 -amended irrigation water on tomato and cucumber production.Field experiments were conducted in Summer 1990, at Riverside and Irvine, Calif.Soil types were Buren fine sandy loam (mixed, thermic Haplic Durixeralf) in Riverside and San Emigdio sandy loam [mixed (calcareous), thermic Typic Xerofluvent] in Irvine.Raised beds on 1.5-m centers were prepared, with single drip irrigation lines buried 15 cm in the center of each bed.Beds at Irvine were mulched with black polyethylene film.'Dasher II' cucumber (Cucumis sativus L.) seed and 'Bingo' tomato (Lycopersicon esculentum Mill.) transplants were planted on 1 June (Irvine) or 5 June (Riverside); plant population was 17,000 and 29,000/ha for tomato and cucumber, respectively.
