Effects of AuxiGro® WP and Fertilizers on Upland Cotton in the Palo Verde Valley, 2002
MetadataShow full item record
AbstractA field experiment was conducted to obtain data from upland cotton grown under low desert conditions to document of the effects of AuxiGro® WP and treatments consisting of AuxiGro® WP plus various foliar fertilizers on cotton yield and quality. Treatments were applied the morning of July 6, 2002, to DPL 655BR cotton that had begun bloom approximately June 28. Yields and quality data were obtained and economics calculated. AuxiGro by itself did not result in a yield increase, but did so in combination with various fertilizers. Highest quality resulted in the 8 oz/acre rate of AuxiGro + Foliar Pride fertilizer, but highest yields were documented from the 4 oz./acre rate of AuxiGro + CalMax. All treatments increased harvested value of cotton/acre when compared with the untreated check, with the treatment consisting of 4 oz./acre rate of AuxiGro + CalMax worth almost $200/acre more than the untreated check.
