Abstract

The aim of this research was to determine the effect of planting date and the occurrence of pests on the cotton crop. The influence of the planting date on the output of the cotton CNPA 7H and Deltapine Acala 90, at Formosa do Rio Preto, São Desidério and Luiz Eduardo Magalhães, in the experimental fields of the Embrapa, in the state of Bahia, was analyzed. Four planting dates were evaluated. The plantings were in November, December and January, 1998/1999 and 1999/2000 crops, with intervals of 15 days between each planting. The data were submitted to analysis of variance and the averages compared by Tukey’s test at 5% probability. According to the results, the following conclusions can be inferred: a) The planting date has a significant influence on the cotton production; b) The cotton planting date influences the occurrence of pests, leading, thus, to a significant decrease in the production.
