Study of the mineral composition of some forage plants from areas of Mato Grosso do Sul State - Brazil. IV. Zinc

Abstract

It was carried out a survey on zinc levels in four grasses - Colonião (Panicum maximum Jack), Jaraguá (Hyparrhenia rufa (Ness) Stapf), Pangola (Digitaria decumbens Stent) and Angolinha (Eriochloa polystachya (H.B.K.)Hitchic) - collected monthly at the city of Brasilândia, Mato Grosso do Sul, Brazil. The Jaraguá grass showed the highest zinc level - 39,3 ppm - which was significantly greater than obtained in Colonião — 22,7 ppm - and Pangola — 26,0 ppm — grasses. There was no difference between Jaraguá and Angolinha - 35,1 ppm - levels.
