Two drip irrigation rates and two emitter placements on tomato production

Abstract

The effects of two drip irrigation rates and two emitter placements on tomato production were investigated in the U. S. Virgin Islands. There was significant difference in yields between irrigation rates but none between emitter placements. With tomato variety N-69, marketable yields of 45 and 55 tons/ha were obtained from irrigation rates of 5.2 and 9.9 mm per week, respectively. The relationship of production to rainfall and potential evapotranspiration is discussed.
