Methods to Evaluate Peanut Maturity for Optimal Seed Quality and Yield

Determining when to dig is one of the most important economic decisions a grower must make. Peanut (Arachis hypogaea L.) poses a unique challenge for maturity determination because it is an indeterminate crop that forms pods underground. This 8-page fact sheet discusses maturity assessment methods as well as steps for collecting and evaluating a maturity sample.

Field Symptoms of Boron Toxicity and Deficiency in Florida Peanuts (SL366/SS567)

Figure 2. Close-up photo of classic boron toxicity foliar symptomsBoron is an essential micronutrient needed by peanut to prevent “hollow heart” and to provide for sufficient plant growth, but it can be a challenge to manage for peanut production on sandy soils. There may be times when peanut growers, extension agents, and consultants find field symptoms when either boron toxicity or boron deficiency is the cause of peanut yield loss and low kernel quality. This 4-page fact sheet reviews the boron management strategy in Florida, presents information on boron sufficiency and toxicity levels from the literature, and provides photographs of field symptoms that can be used by growers and Extension agents. was written by J. W. Breman, W. D. Thomas, H. E. Jowers, and R. S. Mylavarapu, and published by the UF Department of Soil and Water Science, May 2012.

AN255 The Annual Cultivated Peanut (Arachis hypogaea L.) as a Potential Forage Crop for Livestock in the Southeastern U.S.

AN255, a 5-page fact sheet by R. O. Myer, A. T. Adesogan, A. R. Blount, D. W. Gorbet, and B. L. Tillman, provides livestock producers with information on the use of annual cultivated peanut as a potential forage crop in the Southeast — forage production trial results, nutritional value, feeding value, and use as forage for grazing. Includes references. Published by the UF Department of Animal Sciences, December 2010.
