(ID n. 20-05).  aCNPGC.  aForage productivity was evaluated for Panicum maximum pastures established after 4 years of soybean cultivation in the summer (PM-SO), and 4 years of rotation of soybeans in the summer and millet for winter grazing (PM-MI). In the PM-MI pasture, biomass and dry matter production were much lower than in the PM-SO, and the amount  of copper and nitrogen in  the top part of the plants in PM-MI were significantly lower than that in PM-SO. Thus,  it was  considered that the  shortage of copper and nitrogen restristed photosynthesis and forage production in PM-MI.  acopper  amillets  anitrogen  apastures  asoybeans  aTanzania  aCobre  aMatéria Seca  aMilheto  aNitrogênio  aPanicum Maximum  aPastagem  aSoja  aAgropastoral systems  aDry matter  aIntegração agricultura pecuária1 aMACEDO, M.
