Purslane ( P. oleracea ) is a problematic succulent weedy annual in horticultural crop production in the United States ( Armel et al., 2012 ). However, in other parts of the world purslane is grown as a specialty crop, valued for its nutritional
Abstract
Vegetable garden planning software for personal computers is gaining in popularity (3). The program described herein (GARD-PLAN) provides a listing of vegetable crops from which the user makes selections. Cultural recommendations are made, and yields are projected based on the selections made in the program. A 3-year study to determine the dollar value of vegetable gardens in the 40 counties in North Dakota showed that the average value per garden was about $400, with the highest-valued garden at over $1200 (1). Therefore, vegetable gardening can result in significant savings relative to fresh produce purchased during the growing season.
Interest in growing vegetables, fruits, and flowers in rudimentary greenhouses covered with a single layer of polyethylene has been increasing in North America in recent years ( Carey et al., 2009 ). These high tunnels offer a low-cost method of

of nitrogen should be applied each year for vegetable crop production ( Saha et al. 2016 ). This is much greater than the 7.03 g/m 2 of nitrogen recommendation for ornamental green roofs ( FFL 2002 ). Rooftop farmers compensate for this difference in
Vegetable transplant production in high-density plug trays can induce excessive stem elongation as a result of shade avoidance responses ( Marr and Jirak, 1990 ; Smith, 1994 ). The resulting spindly transplants are generally considered unsuitable
Global vegetable production grew 65% between 2000 and 2019, producing up to 1128 million tonnes in 2019 ( FAO 2021 ). The increase in worldwide production is due more to increased use of inputs (e.g., fertilizers, irrigation, pesticides), high
