Descriptif
The overall objective of this project was to examine the influence of irrigation levels and irrigation delivery methods on crop growth and development and its resulting influence on cotton arthropod seasonal activity patterns. The specific objectives of this study were to : (1) Determine the influence of irrigation regimes and crop cultivar on cotton growth phenology, yield, and lint quality characteristics. (2) Determine the seasonal activity and abundance patterns of pest and beneficial cotton arthropods in relation to irrigation regimes and cultivar. (3) Compare the relative efficiency of vacuum and sweepnet sampling methods in estimating arthropod abundance in THP cotton. The outcome of this research project is expected to provide ecological information on the interaction of irrigation management (irrigation amount and delivery method), crop growth phenology, and arthropod activity. The resulting information on reliable and cost effective sampling plans will have direct applications in cotton crop management at the producer level.
