Yield Uniformity of Cotton Irrigated with Drip IrrigationBriggs, R. E.; Maatoug, M. A.; Hofmann, W. C.; Taylor, B. B.; Stedman, S. W. (College of Agriculture, University of Arizona (Tucson, AZ), 1983-02)
Effects of High Frequency Irrigation on Irrigation Uniformity IIIMartin, E. C.; Laine, G.; Sheedy, M.; Silvertooth, Jeff; University of Arizona, Cooperative Extension (College of Agriculture, University of Arizona (Tucson, AZ), 2001)Data was collected for a third season to determine the effects of high frequency irrigation on irrigation uniformity in cotton production. The past two seasons indicated that high frequency irrigation worked better on sandier soils than soils containing high clay contents. Although no significant differences were found, higher yields were obtained on a site with a relatively high sand content. A field located at the Maricopa Agricultural Center was split into two treatments. Treatment 1 was irrigated at approximately 35% depletion of available water in the plant rootzone. Treatment 2 was irrigated at approximately 50% depletion in the crop rootzone. Although the yield data from Treatment 1 was higher on the average, statistically, there was no difference between the two treatments.
