Protection by row covers for winter and spring freeze protection of
strawberrieswas documented; but no difference in total marketable yield,
yield/plant or fruit size was observed. Row covers increased early yield. A
microcomputer program, FROSTPRO, was developed to calculate irrigation rates
for frost/freeze protection of orchards based on given atmospheric and crop
parameters. The best method to calculate heat units to predict harvest date
was determined for cucumbers from a comparison of fourteen methods. In a
subsequent test, the heat-unit method predicted harvest date of processing
cucumbers significantly better than the standard method. Methods of
calculating heat units for post-bloom periods of apples were correlated with
number of days from full bloom to harvest date. No difference in methods was
observed. Methods did not improve harvest prediction accuracy over using the
average number of days. Field frost/freeze protection of tomato and pepper
transplants by two cryoprotectants proved both materials ineffective below
-3.5 C and -1.0 C in separate events. Yield differences were not observed
between treated and untreated plants. Survival compared in seven vegetation
management programs (VMP) found fraser fir survival decreased in bare soil,
but Norway spruce survival was not affected by management program. Norway
spruce growth was not affected by aspect, but fraser fir was larger (height
and stem diameter) on the south aspect when grown in bare soil.
