Relationship between nitrogen and other chemical components in kikuyu grass from long-established pastures (Short communication)

  • 1990
  • Issue: 3
  • Volume: 20
J.P. Marais Page: 147 - 151

The relationship between nitrogen and other components in kikuyu grass (Pennisetum clandestinum) from long-established pastures was investigated. Leaf material, when compared to stem tissue, was higher in total organic nitrogen and protein content, but lower in non-protein organic nitrogen, nitrate,…
