  1. Agricultural research and extension update Senthold Asseng SECC Fall Planning Meeting Gainesville, FL, 13-15 November 2013

  2. Climate science Ag research Ag extension

  3. SECC Planning Meeting: Agriculture • Tallahassee, Nov 2-4, 2011 • Cross-cutting theme – climate data • Seasonal forecast • Production • Pest, diseases, weeds • Climate change • Production • Pest, diseases, weeds

  4. El Niño-Southern Oscillation (ENSO) Effects on Hessian Fly Infestation in the Southeastern USA Prem Woli, Brenda Ortiz, David Buntin, Kathy Flanders • Hessian Fly Infestation is significantly lower in El Niño than in the other phases of ENSO Observed data from field trials 

  5. Corn Aflatoxin Contamination Risk Prediction Based on a Drought Index Damianos Damianidis, Brenda Ortiz, Gary Windham, Prem Woli • Probability of aflatoxincontamination using the Agricultural Reference Index for Drought (ARID) • Determined time windows during the growing season when changes in drought conditions will change the risk for aflatoxin (soil type and corn hybrids)

  6. Web Service for Disease Forecasting • G. Buol, Gail Wilkerson, H. Dinon, A. Wooten, and R. Boyles • State Climate Office API provides on-demand current and historical climate data • Utilizes 7-day, hourly NWS forecasts • Calculates leaf wetness duration, disease infection risk index • Botrytis and anthracnose fruit rots (strawberries) • Generic disease model Infection risk

  7. Reducing Climate Risks In NC Soybean Production Gail Wilkerson, G. Buol, A. Wooten, H. Dinon, and R. Boyles • Summer rainfall and temperature patterns in soybean producing region of NC • vary with spring ENSO phase (Mar-May ONI) • Can reduce risk of drought stress during most • critical period of crop growth through planting date • and Maturity Group selection (Figure shows average • drought stress index following El Niño spring)

  8. Clyde Fraisse et al. Real time monitoring of basic weather variables Track rainfall, growing degree days, average temperature and ARID during the growing season AgroClimate is now a registered vendor at the Apple and Google Play stores

  9. Kati Migliaccio Clyde Fraisse Kelly Morgan George Vellidis Software Developer Jose Andreis

  10. UGA Smart Sensor Array: 12 farmer fields in the Lower Flint George Vellidis et al. www.flintirrigation.com file

  11. KofikumaDzotsi, James W. Jones (UF), Gerrit Hoogenboom (Univ. of Georgia) and Bruno Basso (Univ. of Michigan) Rainfall variability • Area: 3100 km2 • 46 tipping bucket rain gauges • 4 weather stations • 30 farms

  12. KofikumaDzotsi, James W. Jones (UF), Gerrit Hoogenboom (Univ. of Georgia) and Bruno Basso (Univ. of Michigan) Pair-wise correlation of daily rainfall amount between location and simulated impact Simulated impact

  13. Winter-seasonalForecast Melissa A. Ramírez-Rodrigues, Senthold Asseng, Lydia Stefanova, Brenda Ortiz, Clyde Fraisse, Diego Valderrama and Salvador GezánUniversity of Florida,Florida State University, Auburn University • Use of GCM-basedforecasttomanagewheat in Southeast U.S. HL Headland, AL HV Huntsville, AL MA Madison, FL AT Athens, GA TI Tifton, GA LU Lumberton, NC.

  14. “Back to the Future” – Using Historical Climate Observations for Climate Change Assessment Davide Cammarano, David Zierden, Lydia Stefanova, Senthold Asseng, James J. O’Brien, James W. Jones • Using historical warm/cold periods for future assessments

  15. Climate Change Research at U Kentucky • Field study to evaluate genotype specific management for N use efficiency(drought and N carryover) • High NUE genotypes will be more tolerant to heat stress caused by climate change (Staggered planting dates: Sept, Oct, Nov) • Genetic controls (photoperiod sensitivity and vernalization requirement) of responses to warming (buried heating cables; rhizosphere 3-5 ° C above ambient). David Van Sanford, Rebecca McCulley, K. Hitz, Kathleen Russell

  16. Fact Sheets Pam Knox, Melissa Griffin, Clyde Fraisse, Brenda Ortiz & Mark Risse • Fact sheets are designed for Extension agents to use in communicating about climate issues to farmers in a simple, low-tech way.

  17. Pam Knox, Melissa Griffin, Clyde Fraisse, Brenda Ortiz & Mark Risse http://www.agroclimate.org/seclimate/extension-resources/

  18. Pam Knox, Melissa Griffin, Clyde Fraisse, Brenda Ortiz & Mark Risse • 15-hour online course on Animal Agriculture and Climate Change produced through NIFA (eligible for continuing education credits)
