The purpose of this study was to determine if precision farming methods can be used in cotton production systems and maintain profitable fields. The field was disked three times and hipped in the spring to prepare the beds. Fertilization and herbicide practices follow state recommendations for cotton production. For treatment evaluation purposes, the field was subdivided into 25 8-row plots varying in length from 200 to 1,400 ft. The nematicide regimes were either a conventional or variable rate application.
Conventional applications refer to a uniform rate of nematicide applied to the entire plot.
Conventional application rate was based on the mean population densities from the acre subplots that correspond with an individual strip. Variable rate application refers to different rates of nematicide being applied within a plot based on the nematode density map created from the acre subplots. 15 G was also applied as a sidedress. On 12 Jun, plots were established using a randomized complete block design with five replicates per treatment. 3 prior to initiation of the study.
