 fertility during plant and fruit production on growth and fruiting of
 strawberry. HortScience 20(3):411-413.

 Strawberry plants (Fragaria X ananassa Duch. 'Dover' and 'Florida Belle')
 produced increased December fruit yields during 2 seasons when stored at
 20C for 1 week prior to transplanting rather than transplanting directly from
 the nursery. The total fruit yield of 'Dover' decreased with storage the 2nd
 season, whereas the total fruit yield of 'Florida Belle' was inaffected by
 storage. Lowering the soil fertility in the nursery prior to plant harvest
 increased 'Dover' December fruit yield the 2nd season, and increased
 'Florida Belle' December yield both seasons. Total fruit yields of both
 cultivars as related to nursery fertility were inconsistent. Total fruit
 yields of 'Dover' in both seasons were greater with a fertilizer application
 in the fruit production field of 224N-50P-224K kg/ha-1 than with double this
 application. Total fruit yield of 'Florida Belle' was not affected by
 fertilization in a fruiting field. During the first season, both cultivars
 produced more misshapen fruit with the 448N-100P-448K kg/ha-1 application
 than with the 224N-50P-224K kg/ha-1 application.

 transplanting to strawberry fruit yield. HortScience 20(3):415-416.

 Optimum leaf number at transplanting, as related to fruit yield for
 strawberry (Fragaria X ananassa Duch.) plants which had received no chilling
 in the nursery, varied with cultivar. Leaf number optimum for 'Dover',
 'Florida Belle', breeding line 77-163, and 'Pajaro' were 4, 4, 3, and
 greater than 5, respectively.

 vegetables. Proc. Fla. State Hort. Soc. 98:299-301.

 Sweet corn, squash, cucumber, and snap bean were double cropped on strawberry
 beds immediately after fruit harvest ceased. Paraquat was applied to beds to
 destroy all vegetation prior to planting the second crop each season. In 1981,
 mulch remained on beds and fertilizer was applied at either 0, 30-13-25, or
 60-26-50 lb./acre N-P-K. In 1982, polyethylene mulch was removed from one-half
 of the plots. Sweet corn was fertilized at 60-24-50 or 120-48-100 Ib/acre
 N-P-K whereas cucumber, squash, and snap beans received 30-12-25 Ib/acre
 N-P-K. In 1983, all mulch was removed from beds, and crops were seeded at
 2 densities. Sweet corn was fertilized at 50-24-48 or 100-48-96 lb./acre
 N-P-K; cucumber and squash received 25-12-24 or 50-24-48 Ib./acre N-P-K. The
 initial levels of soluble salts at saturation in ppm were 550 in 1983, 3300
 in 1982, and 1700 in 1981 except with cucumber beds which had 2400. Yields
 increased linearly with fertilizer rates with all crops except cucumber in
 1981. Fertilizer rates in 1982 did not affect yields, (probably as a result
 of the high fertilizer carryover) but squash yields increased with use of
 mulch, Only cucumber yields were affected by treatments in 1983, when the
 2x '? ilizer rate and the 12-inch plant spacing gave highest yields. All
 cro-p yields were in the range of state averages. Soil soluble salt
 concentrations were generally positively correlated with fertilizer rates
 only early in the season. In 1982, beds covered with mulch maintained higher
 levels of soil soluble salts all season than the unmulched beds.
