This should retain stink bugs in the ground cover rather than forcing them into the trees. Also, trees should be scouted carefully to determine if stink bug control becomes necessary. Studies thus far indicate the most compatible legume mixtures for pecan orchards as shown in Table 2. Due to seed size differences between legume species, separate seeding operations for each legume are required to achieve the recommended seeding rates. Legume seed should be inoculated with the appropriate Rhizobium spp.
Light disking prior to seeding followed by rolling benefits stand establishment.
Growers should soil test and ensure adequate phosphorous and potassium prior to seeding. Additional information on legume establishment is contained in OSU Fact Sheet F-2585, Forage Legumes for Oklahoma. Either the annual or perennial mixture can be used. However, each mix should include both legumes listed in the pair since each member of the pair complements the other. In the annual mix the vetch lasts longer than the clover.
