Abstract
Strawberry plants (Fragaria ×ananassa Duch. ‘Dover’ and ‘Florida Belle’) produced increased December fruit yields during 2 seasons when stored at 2°C 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 unaffected 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.
Abstract
Optimum leaf number at transplanting, as related to fruit yield for strawberry (Fragaria × 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.
Abstract
Using the annual hill cultural system, runners of 2 strawberry cultivars were removed twice monthly, monthly, or left on the plants during each of 2 seasons. An additional treatment was the transplanting of runners into the planting slits of the original transplants followed by removal of the original transplants when the runners became established. ‘Tufts’ produced 2 to 8 times more runners than ‘Dover’, over a 2 to 3 month period instead of one month as with ‘Dover’. Early marketable yields of ‘Tufts’ were reduced each season when runners remained attached to the fruiting plants, and the total marketable yield was reduced for the 2nd season as well. Yields were reduced because of fewer marketable-size fruit. ‘Dover’ yields were unaffected by runner removal treatments. Early and total marketable fruit yields of the runner plants of both cultivars were reduced each season compared to other treatments. Early yields of ‘Dover’ were greater than those of ‘Tufts’.
Abstract
Bio-degradeable paper mulches with a polyethylene (PE) coating on both sides or with a single PE coating applied against the soil surface satisfactorily endured Florida's 7 month growing season and gave similar fruit yields and fertilizer leaching results as compared to black PE mulch. Paper mulch was harder to transplant through since it is less flexible than PE mulch, but it does not have to be removed from the Geld at season's end.
Abstract
Defoliation of Florida-grown plants of 2 strawberry cultivars at transplanting to simulate leaf desiccation damage which may occur during and after transplanting retarded growth and reduced yields. Fruit no. was linearly correlated with fruit yield while the marketable wt per fruit was unaffected by treatments.
Abstract
Okra (Hibiscus esculentus L. cv. Clem son Spineless) and sweet pepper(Capsicum annuum L. cv. Yolo Wonder L)were grown at 2 fertility levels with treatments of full bed mulch, strip mulch, and bare soil. A black paper coated on both sides with a thin layer of clear polyethylene was used as mulch. Germination of okra and the early growth and seasonal marketable yield of both vegetables were greatest with the full bed mulch treatment. The strip mulch treatments increased yield of pepper over that of the unmulched but had little effect on okra yield. Yields were always higher with the higher fertility level, but differences were usually not significant. Pepper fruit size and no. and okra pods per plant were increased by mulch treatment. As amount of bed covered by mulch increased so did the soil NO3 and K. Higher fertilizer rates generally increased soil NO3 and K but differences were significant only in 1972.
Abstract
A3 × 3 factorial study of soil and foliar-applied N, P, and K fertilizer was conducted on ‘Dover’ and ‘Tufts’ strawberries (Fragaria × ananassa Duch.) using the annual hill cultural system. Rates of soil-applied fertilizer were: a) 0, b) 112N-12P-93K, and c) 224N-24P-186K (kg·ha−1). Rates of weekly foliar fertilizer applications were a) 0, b) 1.20N–0.54P–1.02K, and c) 2.40N–1.08P-2.04K (kg·ha−1). Increasing rates of soil-applied fertilizer increased fruit yields, fruit number, foliar N and K, plant size, and foliage color. Rates of foliar N, P, and K had much less effect than soil-applied fertilizer. The greatest plant response to foliar fertilization was with inadequate rates of soil fertilizer. Foliage damage was evident with foliar fertilization, and damage was greatest with the highest foliar rate.
Abstract
Four cultivars of okra (Abelmoschus esculentus (L.) Moench) were grown with densities of 22, 65, and 130 plants/square meter on polyethylene mulched beds. Within cultivars, pod number and marketable yield per unit area were not affected by plant density, but pod number and marketable yield/plant decreased with increasing density. Average pod weight with 3 of 4 cultivars was inversely related to plant density. Stalk diameter decreased with increasing density, and plant stunting occurred at the highest density.
Abstract
Plant density of okra (Hibiscus esculentus L. cv. Clemson Spineless) was varied from 16, 32, to 64 plants/m2 using 1 or 2 rows/bed and 2.5 or 5 cm in the row spacing. Yield per unit area increased linearly with plant density on a double logarithmic scale. Plant density and pod size were inversely related while the percent marketable pods were unaffected by treatments. The fertility rate did not affect yield responses, but the higher rate increased soil soluble salts, K, and NO3.
Abstract
‘Florida Belle’ is a high yielding, large-fruited strawberry (Fragaria × ananassa Duch.) that has consistently shown good performance for the fresh market in trials in central Florida.
