). Watermelon production is responsible for ≈7% of world vegetable production acreage ( Food and Agriculture Organization of the United Nations, 2011 ). However, very little is known about the control of flowering time in this monoecious crop. Commercial

Triploid (seedless) watermelon production requires the use of diploid (seeded) cultivars to ensure pollination ( Dittmar et al., 2010 ; Fiacchino and Walters, 2003 ; Maynard and Elmstrom, 1992 ; Rhodes et al., 1997 ). This is accomplished by

The increasing popularity and market share of triploid (seedless) watermelons is attracting farmers into growing this fruit type ( Blank, 1999 ; Lucier and Lin, 2001 ). Furthermore, watermelon demand is switching into smaller individual melons to

Watermelon vines and foliage are often damaged or restricted by mechanical operations, diseases, and insects. There is little information to indicate the optimal ratio of plant foliage to fruit. Most watermelon fruits are produced near the plant crown, and thus some farmers believe that extensive foliage is nonessential for fruit production. Experiments have been conducted with watermelon [Citrullus lanatus (cvs. Sangria, Crimson Trio, and Scarlet Trio)] in Oklahoma to determine the relationship between soil surface area covered by foliage (foliar area) and fruit yield. Watermelon plants were planted on 4-m row centers, and were either pruned to allow a foliar area that was 1, 2, 3, or 4 m wide, or were physically confined to the same foliar area by redirecting the branch tips back into the row toward the base of the plant. There was a linear increase in yield as foliar area increased with both `Sangria' and `Scarlet Trio', but not necessarily with `Crimson Trio'. Within a given foliar area, pruning the foliage and confining the foliage to a similar area produced similar effects on fruit yield. A second experiment was conducted to determine the effect on plant yield when the vines were physically moved, as occurred with the confined area treatments. In this study, physically moving the vines did not reduce yield as compared to vines that were not moved.

Watermelon growers are advised to grow melons in a given field no more than 1 year out of 4. Bermudagrass pastures are abundant in the southern U.S., but ranchers are reluctant to destroy a pasture for 1 year and plant it with melons if they must then re-establish a sod. A project was designed to develop a system for growing watermelon in a permanent pasture with only a minimal amount of tillage, and without destroying the established forages in the pasture. The approach is to compare and evaluate several techniques for growing watermelons in strip-tilled areas within a permanent pasture. These techniques include cultivation, plastic mulches, and herbicides applied to 2-m strips separated by untilled bermudagrass. Research was done in 1996 at two university research centers in Oklahoma and Texas. The treatments with greatest watermelon yields, in decreasing order, were black polyethylene mulch, hand-weeded control, photodegradable mulch, biodegradable mulch, cultivation plus sethoxydim, sethoxydim alone, cultivation alone, and the weedy check. At harvest, 63% of the area in the cultivation alone treatment, 40% of the area in the plastic mulch treatment, and 1% of the area in the sethoxydim treatment were covered with a regrowth of bermudagrass. Forage was also collected from row areas of plots. Forage amounts, in decreasing order, were from cultivation alone, weedy check, sethoxydim alone, photodegradable mulch, polyethylene mulch, biodegradable mulch, cultivation plus sethoxydim, and the clean control.

The cucurbit crops ( Cucurbitaceae ) that are grown most commonly in the United States are cucumber, melon, and watermelon. In 2005, U.S. production was 570,720 tons of processing cucumbers, 10,232 thousand cwt of fresh-market cucumbers, 22
