Mediterranean region lead in protected environment agriculture. In the United States, interest in high tunnels has surged since 1990. Today, crops are grown under high tunnels in 45 states and high tunnel research and demonstration projects have been established

unique alkaloid restricted to Capsicum species ( Suzuki and Iwai, 1984 ). There is increased use of the capsaicinoids in pharmacy products, sprays for riot control, self-defense, and the pesticide industries ( Shur, 2002 ). Capsaicinoid accumulation is

preemergence herbicides improve weed control in spring zucchini production Vegetable growers have been reluctant to use no-tillage practices due to the lack of sufficient weed control. There are few herbicides available to control broadleaved weeds in most

. Based on heritability and G×E interaction, lycopene was the most environment-sensitive trait, whereas TTA content was the least sensitive. The greater the level of environmental sensitivity, the less likely it will be to control and predict the

test for CRFs and SRFs for commerce purposes ( European Committee for Standardization, 2002 ; Sartain et al., 2004 ). Growth chamber and greenhouse methods are used to evaluate or compare how CRFs will act in a particular controlled environment

. Studies of disease susceptibility in controlled environments Plant species and varieties for these studies were chosen based on the known host list of S. sclerotiorum ( Boland and Hall, 1994 ; Farr et al., 1989 ), the 2009 University of Minnesota annual

that data and irrigation settings are correct, if the node irrigates longer than commanded because of a bad packet that can cause problems. The second reason is that agricultural environments often have hills, valleys, trees, building, power lines, and

sustainable controlled agriculture. In this study, the use of supplemental CO 2 was explored in combination with reduced temperatures. The objective was to compare lettuce growth within a low-temperature greenhouse supplemented with CO 2 against lettuce
