Summary
Polyethylene-mulched tomatoes (Lycopersicon esculentum Mill.) were grown with drip irrigation to evaluate the effects of water quantity, and time of N + K application on fruit production. Water quantities applied were 0, 0.17, 0.34, and 0.05 times pan evaporation. The N + K applications were 100% preplant or 40% preplant with 60% applied by drip irrigation in daily or weekly applications. Rainfall was low during the season and irrigation increased the fruit yield of extra large, large, and total marketable fruit by 76, 44, and 40%, respectively. Total marketable yields increased linearly from 2300 cartons to 2516 cartons/acre with an increase in water applied from 0.17 to 0.50 times pan. Extra large, large, and total marketable fruit yields were higher while yields of medium-size fruit were lower with N + K applied with drip than all applied preplant. Fruit yields were similar with daily or weekly N + K applications. Leaf tissue N and K concentrations at early harvest with all preplant applied N and K were lowest with 0.17 pan water quantity and similar with 0.34 and 0.50 pan. Water quantity had less effect on leaf N and K with drip applied N and K treatments. [AS]
