International collaborators attend events in USA

PeanutTour043A group of International PMIL Collaborators from Africa and Haiti were joined by partners from the USA, during 2 weeks in July of 2015, to tour the USDA core germplasm collection planted at the University of Florida’s Plant Science Research and Education Unit in Citra, Florida USA. Most of the partners then traveled to Charleston, South Carolina to attend the annual meeting of the American Peanut Research and Education Society.

Greg MacDonald describes field tour in Williston, Fla., USA, with visiting African scientists and PMIL collaborators

We visited with farmer Andy Robinson of 35 Farms, Williston, FL.  County agent Andrew Drew of Levy county hosted us. We traveled to Andy’s farm where we discussed his practices and farming operations for growing peanuts – specfically for peanut seed production. Andy discussed his fertility operations and told the group he uses site specific application techniques based on 1 acre soil grid sampling. Because of his unique soils (very deep coarse sand) he uses more potassium fertilizer and calcium compared to normal growers. He also utilizes a unique fungicide program.  Anthony Drew discussed maturity profiling as a method to determine when to harvest and also to maximize quality peanuts for seed.

PMIL Lead Scientist Greg MacDonald in Growing Georgia: Researching 1,500 Peanuts, One Variety at a Time

In the late 1990s, tomato spotted wilt virus took a bite out of peanuts in the Southeast, claiming half of some farmers’ crop and about 10% of the overall yield in 1997. One of the most important factors in the battle against TSWV was lurking in a peanut variety from South America, which had natural resistance to the virus.

“We were seeing 30 to 40 percent reductions in yield,” said Greg MacDonald, a weed scientist and agronomist who is working to evaluate and chronicle the traits of hundreds of varieties of peanuts stored by the U.S. Department of Agriculture. “Most all the runners now can be traced back to that one line, which is one of the reasons we maintain the collection.”
