 established by overhead sprinkler irrigation operating for about 8 hours
 daily for a period of 10 to 14 days. Intermittent irrigation can be
 employed to give a considerable reduction in water use if the following
 guidelines are met: 1) turn irrigation on as soon as plants are set; 2)
 throughly moisten transplants and mulch during the time irrigation cycle
 is on; 3) resume the irrigation "on" cycle before the plants become dry;
 4) do not permit the plants to wilt excessively during the "off" cycle; and
 5) during hot, dry, or windy weather "on" cycle must be longer and "off"
 cycle must be shorter.

 irrigation on establishment of strawberry transplants. Soil and Crop Sci.

 Diurnal intermittent sprinkler irrigation intervals (min on/min off) of
 3/17, 5/85, 5/15, 10/20, 15/15, and continuous the first season, and 5/25,
 5/15, 5/10, and continuous the second season were evaluated for establishing
 strawberry (Fragaria X ananassa Duch.) transplants on black polyethylene
 mulched beds. Leaf loss during the establishment period generally increased
 with increased length of the 'off interval' and decreased length of the
 'on interval'. Plant mortality was greater with the 3/17 and 5/25 treat-
 ments. Seasonal yield was reduced the first season with the 5/25 treatment.
 January yield was reduced with the 3/17 and 5/25 treatments. Leaf number
 and plant mortality after establishment were the principal variables which
 affected fruiting response.

 This report contains weather data for the Agricultural Research and
 Education Center at Dover, Florida for the year 1985 and historical
 information and averages for the years 1929 through 1985.

 The present weather station is located 7 miles west of Plant City. Until
 November of 1963, the weather station was located at Springhead, about
 three miles southeast of Plant City. All precipitation measurements were
 made at 8 a.m each day and represent the previous 24 hour period.
 Temperature data is taken at 8 a.m. in a standard weather instrument
 shelter approximately 4 feet above the ground and the data is the recorded
 high and low for the previous 24 hours.

 protection during a radiation freeze. Soil and Crop Sci. Soc. Fla. Proc.

 Thermocouples were attached to the surface of strawberry (Fragaria X
 ananassa Duch.) flowers to monitor their temperatures during freezes.
 Flowers and thermocouples were located above the foliage and exposed to
 the sky. During radiation-type freezes, water was supplied by overhead
 sprinkler irrigation for 15 min and then shut off until thermocouples
 reached -1.1, -1.7, or -2.20C or for 15 or 30 min, whichever came first.
 Air temperatures were monitored in weatherhouses located either 1.2 m
 above the soil surface or on the ground, and also with unpainted and
 exposed thermocouples located on black polyethylene non-irrigated beds.
