Fertilizer and pest control chemicals were applied uniformly to all

plots. Row width was six feet and distance between plants was 20

inches. Plots were mulched and staked as in experiment #1.

 Two frequencies and four rates of drip irrigation were

compared in a factorial arrangement. Daily irrigation was compared

with irrigation applied Monday, Wednesday, and Friday (MWF) for a

given amount of water per week. The four irrigation rates were 25,

50, 75, and 100% of 0.2 inches d'1 from 8 April to 15 May and 0.3

inches d'1 from 16 May to 15 July. An automatic timing system

turned irrigation on and off for individual treatments. Emitter

(12 inch spacing) flow rates from twin wall drip tubing

manufacturer's specifications were used to calculate the time

required to apply each irrigation rate.

 Rainfall and evaporation data for Exp-1 and Exp-2 were

obtained from weather records maintained by the National Oceanic

and Atmospheric Administration (NOAA).

 Mature green and pink fruit were harvested on each of the

following dates: 23 and 29 June and 7 and 15 July. Yields are

reported as marketable fruit in tons per acre.

 Experiment #3: Plywood boxes 36 x 20 x 18 inches (L x D x W)

containing 6 inches of topsoil over 12 inches of subsoil were used

to grow plants of the Sunny tomato cultivar under a transparent

rain shelter. The soil, Greenville loamy fine sand clayeyy,

kaolinitic, thermic, Rhodic Kandiudults), was packed approximately

to field bulk density. Fertilizer materials and chemicals for pest

control were applied uniformly to all treatments.
