Effects of Foliar Fertilizers on Hail and Wind Damaged Cotton

M.G. Hickey and C.W. Bednarz


 
ABSTRACT

A study was conducted on hail damaged cotton (Gossypium hirsutum L.) on the Texas southern high plains to determine the effects that foliar applied fertilizers may have on the recoverability of this injured crop. Sites were located on cooperator farms in Lubbock, Hale, and Hockley counties. Treatments consisted of three rates of urea solutions, two rates of a commercial mixture, and an untreated check. Twenty-four days following the initial treatment plants were mapped to determine the number and location of fruiting forms and collected for dry weight. Lint yields were determined following crop termination. Hail damage resulted in moving the first fruit retained up the plant one to two nodes. Dry weights and number of first and second position fruit as a function of foliar fertilizer treatment were not statistically different. Dry weights at the Hale and Lubbock county sites, however, were lowest for the with the high commercial mixture rate. Dry weights and number of first and second position fruit increased as a result of foliar fertilization at the Hockley county site. Final lint yields within each location were not statistically significant, and were adversely affected by the environment.
