Vegetable Crop Response to Subsurface Drip Irrigation

Rubeiz, I. G., Oebker, N. F., Stroehlein, J. L. 04 1900 (has links)
Drip irrigation lines placed 15 cm (deep) and 5 cm (shallow) below soil surface were compared to furrow irrigation with zucchini squash as a summer crop and cabbage as a winter crop. Both crops were grown on the same drip lines in each treatment. Urea phosphate was injected in drip lines during growing season while the furrow-irrigated plots received preplant application of phosphorus. In squash, deep lines produced higher yields than did shallow. Deep-drip yields were comparable to those with furrow but used half the water and half the fertilizer. In cabbage, deep-drip yielded slightly higher than shallow-drip and furrow. In these studies, deep-drip was superior in applying water and fertilizer.

Urea Phosphate Applied by Subsurface Drip Irrigation Increases Availability of Soil Nitrogen and Phosphorus

Stroehlein, J. L., Rubeiz, I. G., Oebker, N. F. 04 1900 (has links)
Application of water and fertilizer through buried drip lines shows promise for vegetable production in Arizona. Use of an acidic product is necessary if phosphorus is added through the system. Urea phosphate was shown to be a satisfactory product for injecting into buried drip lines for squash and cabbage.

Plant Virus Diseases that Threaten Cucurbit Production in Arizona

Brown, J. K., Goldstein, D., Nelson, M. R. 04 1900 (has links)
A number of plant viruses were isolated from diseased cucurbits in Arizona during 1982 -85. Watermelon mosiac virus 2, cucumber mosaic virus, and squash mosaic virus are previously recognized viral pathogens in Arizona and in most years are not considered economically threatening to cucurbit production. Three newly described plant viruses (lettuce infectious yellows, watermelon curly mottle and zucchini yellow mosaic) however, have the potential to, or already have, incited serious epidemics in Arizona. Losses are heaviest with these diseases when insect vector levels build up early in the growing season and plants become infected during critical developmental stages.
