Magnesium deficiency in zoysiagrass

  1. Y. Kamon

Abstract

Proneness to magnesium deficiency symptoms was evaluated on three warm-season turf grasse s. The severity of deficiency symptoms ranked in order from most severe to least was: zoysiagrass (Zoysia spp.) > centipedegrass [Eremochloa ophiuroides (Monroe.) Hack.] > bermudagrass (Cynodon spp.). However, the initial rate of appearance of magnesium deficiency was in the order from most rapid to slowest: centipedegrass > bermudagrass > zoysiagrass.

Six levels of magnesium oxide were utilized to investigate magnesium deficiencies in zoysiagrass. The levels used were 0, 5, 10, 20, 30, and 40 ppm. The plant characteristics evaluated included leaf color, leaf length, leaf width, node number, shoot length, shoot weight, root length, and root weight. In this experiment zoysiagrass showed magnesium deficiency symptoms at levels below 20 ppm. Leaf length was increased up to 10 ppm, while shoot length and shoot weight were increased up to 20 ppm. The number of nodes increased up to 40 ppm. Leaf width, root length, and root weight were not affected by the magnesium level. Additional index words: Bermudagrass, Centipedegrass, Shoot growth, Root growth, Zoysia spp., Cynodon spp.
