Over the past several years, agriculture techniques have been developed that allow more precise lime, fertilizer, and pesticide application. Techniques for adapting crop-seeding rates to yield goals are now possible and will become more valuable as the technology advances. Drones allow public and private crop advisors to observe the crop from a completely different viewpoint. As this technology develops and research data sets are more complete, real-time in-season management will become more advanced as well. The Alabama Agricultural Experiment Station has made a large investment in the past 3 years in variable rate irrigation (VRI). Within the next year, VRI will be possible at the TVREC in Belle Mina, SMREC in Crossville, GCREC in Fairhope, and WGREC in Headland. Currently, field scale, variable rate center pivot irrigation is being utilized at the EVSRC in Shorter, AL. Greg Pate, EVSRC director, has been working with Dr. Ortiz, Dr. Hagan, and others to conduct research that will make full use of this new technology.

Our objective in 2016 was to assess the yield response of eight cultivars on irrigation depth.
