Gypsum Rates for Virginia and Runner Market Types Peanut Notes No. 102 2020
We recommend the full rate of gypsum for Virginia market types (see page 28, table 3-6 in 2020 Peanut Information) and at least one-half the Virginia market type for all runner market types. Apply gypsum of peanuts planted in May as soon as possible. Apply gypsum on peanuts planted in June by July 20. If rainfall delays applications, peanuts still need supplemental calcium through the first week of August.
