ENHANCING THE WATER-USE EFFICIENCY AND DROUGHT SUSTAINABILITY OF COTTON PRODUCTION THROUGH MANAGEMENT USING REDUCED TILLAGE AND PRIMED ACCLIMATION
Diane L. Rowland, Josh Thompson, Jay Ferrell, University of Florida and Wilson Faircloth, USDA-ARS
This project has the primary objective of comparing cotton cultivars in their yield and quality between conservation and conventional tillage systems under primed acclimation and deficit irrigated, as well as dryland production conditions.
Field plots were established at the University of Florida's Plant Science Research and
This research has documented the feasibility of utilizing strip tillage for both irrigated and non-irrigated cotton production in north central Florida on deep sands. The benefits over conventional tillage often associated with strip tillage were not realized in the two years of the study. However, soil and root measurements indicate that this might not have been enough time to fully achieve the soil enhancing properties associated with strip tillage. Overall, these results also indicated that there was no detriment to using strip tillage on this soil type and, when factoring the lowered fuel costs associated with strip tillage, there may be an economic benefit to the use of conservation over conventional tillage systems. This research has validated this production system in this region and provides southeastern cotton producers a cropping system that is sustainable and with possible water conservation characteristics with longer periods of adoptability.
