The practice of applying mulches for the production of vegetables dates back thousands of years ( Coolong, 2012 ; Rowe-Dutton, 1957 ). A primary purpose for using mulches is for weed suppression in the crop to be grown. Mulches typically function

international markets. Ridge and furrow rainwater-harvesting (RFRH) systems with mulches were first researched in the flat, lowland, semiarid conditions of northwest China ( Li et al., 2000 , 2001 ) to improve water availability and to increase crop production

`Crimson Sweet' watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] plants were grown with various mulches and rowcovers and analyzed for relative growth rate (RGR), net assimilation rate (NAR), specific leaf area (SLA), leaf area index (LAI), and crop growth rate (CGR). Spunbonded polyester fabric (SB-PF) and perforated polyethylene film (PCP) rowcovers generally showed greater mean RGR, SLA and CGR than spunbonded polypropylene polyamide net (SB-PP), black plus clear combination plastic mulch and black plastic mulch alone. Plants on mulches and under rowcovers showed significant increases in RGR, NAR, and SLA over plants grown in bare soil. Carbon dioxide concentration inside the transplanting mulch holes was nearly twice the ambient CO, concentration. Growth analysis of sampled watermelon plants during early stages of development under various treatments was predictive of crop yield. Plants under SB-PF and PCP rowcovers produced the earliest fruit and the greatest total yield. An asymmetrical curvilinear model for watermelon growth and development based on cardinal temperatures was developed. The model uses hourly averaged temperatures to predict growth and phenological development of `Crimson Sweet' watermelon plants grown with and without rowcovers. Early vegetative growth correlated well with accumulated heat units. Results indicate a consistent heat unit requirement for the `Crimson Sweet' watermelon plants to reach first male flower, first female flower and first harvest in uncovered plants and plants under rowcovers. Greater variability was observed in predicting date of first harvest than first bloom.

current practices could potentially be improved. Mulching The cornerstone of a landscape weed control program is the use of organic or inorganic mulches. Mulches serve several functions in the landscape including moisture retention ( Iles and Dosmann, 1999

In the United States, the market for landscape mulch is increasing ( Satkofsky, 2001 ). In 2006, demand for bagged mulch was predicted to increase by 5.5% per year and annual sales were predicted to increase from around $550 million to $915 million

Polyethylene mulch is widely used for intensive vegetable production worldwide as a tool to control weeds, conserve water, and produce earlier and cleaner products (i.e., less attached soil). Mulched land area has increased during the past two

suppression of weeds may be obtained when alleyway vegetation is mowed at strategic times during vine development and the residue transferred into vine rows as mulch. This method of mulching, known as “mow-and-throw,” has been shown to reduce germination of
