Abstract:
A field experiments was conducted during the 2001 growing season to evaluate the effect of Manganese (Mn) fertility on growth, development, and yield of a commonly grown upland cotton variety in the Yuma Valley of Arizona. This project also provided an evaluation of the University of Arizona (UA) critical level for Mn fertility for cotton (1.0 ppm Mn). The study consisted of two treatments, which included an untreated control and a treatment receiving two foliar applications each of a pint of the product 3-0-0-27.4 using 18gal./acre carrier. Plant growth and development measurements, including estimates of fruit retention (FR) levels and height to node ratios (HNR’s) were similar for both treatments during the season. There was not a significant difference in lint yield between the control (untreated) and the treated plots. These results support the current UA Mn fertility guideline for cotton on not applying Mn when soil test levels exceed 1.0 ppm.
