The effects of black polyethylene (PE) mulch alone and in combination with plastic film tunnels (Agronet, Reemay, whiteperforated, clear, and clear-slitted) were studied on morphology and yield of sweet corn in North Logan, Utah. Yields of "Miracle" sweet corn (Zea mays L.) were increased significantly by using black PE mulch and with a combination of various types of plastic row covers, as compared to unmulched soil. Standard-growth analysis procedures were conducted to verify responses among treatments. Treatment effects were determined by measuring days to first flowering, ear weight, number of side tillers, cob length, cob circumference, cob fill length, number …

Nitrate nitrogen (N03-N) leaching is becoming an alarming threat to ground water in many areas in the U.S. In one study in North Carolina, over 9000 domestic wells were sampled for nitrate. Over 3 percent (288 wells) contained N03-N at levels exceeding the Environmental Protection Agency (EPA) safe drinking water standard of 10 mgIL (Jennings, et aI., 1991). Ground water quality concerns in central Nebraska surfaced in the mid 1950s when scientists observed increasing N03-N concentrations in the ground water of some river valleys (Olson et aI., 1962). In Utah also, excessive N03-N contamination has been found in private wells. …
