Abstract:

Intercropping of seedless watermelon [Citrullus lanatus (Thumb.) Matsum. & Nak.] and cotton [Gossypium hirsutum (L.)] in the eastern geographical area of South Carolina requires changes in normal crop-management programs but has the potential to improve grower profits compared with typical production of each crop separately. The alteration and timing of several normal crop-production practices for both crops can present challenges and must be well-defined for successful intercropping of watermelon and cotton in the region. Notable adjustments in production for watermelon are delayed planti

Watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] cultivars StarBrite and Crimson Sweet were grown during 1991 and 1992 in rows 1.5 m apart at plant spacings of 0.9, 1.5, or 2.2 m. Total fruit yield, marketable fruit yield, fruit-weight distribution, and estimated gross returns were determined for each spacing treatment. Total and marketable fruit yields were greater overall for `StarBrite' than for `Crimson Sweet'. Except for 1991 `Crimson Sweet' yields, marketable fruit yields per unit land area increased 29% to 34% as plant spacing decreased from 2.2 to 0.9 m. The yield component c

One or two plants per hill of `Prince Charles' and `Royal Jubilee' watermelon were grown with drip fertigation at five in-row spacings, with or without polyethylene mulch, in four location × year combinations (environments). Rows were 1.5 m apart and in-row spacings were 45, 60, 90, 120, and 150 cm. `Royal Jubilee' yielded more than `Prince Charles' in all environments, and the highest yields were associated with low percent culls and high fruit numbers per hectare. Highest yields of marketable fruits (≥4.5 kg/melon) were obtained using polyethylene mulch and areas per plant between 0.4 and 0.

Diploid watermelon (Citrullus lanatus) pollenizers are planted within triploid watermelon fields to provide viable pollen for triploid fruit set. In recent years, pollenizer cultivars with desirable characteristics for planting in-row with triploid watermelons have been commercially available. The degree of plant competition from in-row pollenizers grown in the commercially common arrangement where pollenizers are placed equidistant from neighboring triploid plants has not been reported.

Abstract:

The southeastern United States produces 50% of U.S. conventional watermelon (Citrullus lanatus) but only 7% of U.S. organic watermelon. Weeds are a major threat to watermelon yield in the southeastern United States, and organic weed control is estimated to cost 20-times more than conventional herbicide programs. The objectives of this study were to determine the optimal weed control regime to reduce hand-weeding costs while maintaining yield and to compare the weed suppression of two watermelon types with differing growth habits in an organic system.

Significant variation for tuber yield, 90-100 days after planting, was observed in both experiments. The mean yield of spring planting (25.8 Mg/ha with a range of 9.8 to 49.5 Mg/ha) was significantly higher than mean yield of fall-planting (18.2 Mg/ha with a range of 8.5 to 30.2 Mg/ha).

AbstractThe loss of methyl bromide led vegetable growers to rely more heavily on herbicides to control weeds. Although herbicides can be effective, limited options in vegetable production challenge growers. Identifying new, effective tools to be applied over plastic mulch before planting, for improved weed control with minimal crop injury, would be beneficial. The objective of these experiments was to evaluate the persistence of preplant applications of glyphosate (1,125 or 2,250 g ae ha−1) plus 2,4-D (1,065 or 2,130 g ae ha−1) or dicamba (560 g ae ha−1) over plastic mulch, using analytical te

A 1984–1985 and 1988–1989 field study near Pullman, WA, evaluated the effect of two winter wheat planting geometries on the growth of wheat and competition against jointed goatgrass. Treatments included paired and constant row planting geometries of wheat and locations of jointed goatgrass within each geometry. No planting geometry by weed location interactions occurred at any harvest date for plant height, shoot number, leaf area, plant dry weight, or N uptake for either wheat or jointed goatgrass. During the 1984–1985 growing season, N uptake data indicated that by heading, jointed goatgrass

The objective of 2 years of field studies was to begin development of a luffa sponge gourd (Luffa aegyptiaca Mill.) production system for a cool, temperate climate by studying the effects of planting date, planting method, in-row spacing (30.5, 61, and 91 cm), and pruning techniques on yield and quality of luffa sponge gourds. High yields of mature gourds were obtained when transplants were field-set as soon as the danger of frost had past. Highest marketable yields were obtained when plants were spaced 30.5 cm apart in the row and the first four lateral shoots were removed. Plants spaced 91 c

For each rotation, two different planting densities were studied, ranging from 2000 to 20 000 cuttings per hectare. The experiment, which lasted for 6 years, allowed comparisons between establishment and subsequent coppice cycles on relatively large treatment plots (400 stools per plot). The highest planting densities yielded fewer shoots per stool and reduced height and diameter growth. Individual stool biom

AbstractNutsedge species are problematic in plastic-mulched vegetable production because of the weed’s rapid reproduction and ability to penetrate the mulch. Vegetable growers rely heavily on halosulfuron to manage nutsedge species; however, the herbicide cannot be applied over mulch before vegetable transplanting due to potential crop injury. This can be problematic when multiple crops are produced on a single mulch installation. Field experiments were conducted to determine the response of broccoli, cabbage, squash, and watermelon to halosulfuron applied on top of mulch prior to transplantin
