In March 1942, a project was started to study the effect of cultural practices on the yield and quality of garden vegetables. The vegetables were grown under a lath shade and in the open. It was planned to grow a half of the vegetables under irrigation, but due to the wet season this phase of the experiment was omitted. The lath shades were supported on frames two feet and three feet above the low and tall growing vegetables respectively. These shades were used throughout the growing season. Three fertilizer treatments, including manure, Vigor, superphosphate, and a check plot were used on each of the above treatments. Nineteen vegetables listed in the accompanying tables, were grown. The yields represent fourteen feet of row for all of the vegetables except cucumbers, eggplant, peppers, tomatoes, potatoes and sweetcorn where thirty-two feet of row was used. Spacing between rows was three feet for the fourteen foot rows and four feet for the thirty-two foot plantings.
