Effects of shading on vetiver development (Chrysopogon zizanioides L.) under greenhouse.
Effects of shading on growth and development of vetiver (Chrysopogon zizanioides L.) have been investigated under greenhouse. The results showed that the growth of vetiver is significantly influenced by shading. Indeed, the shading have been induced an increasement 50% number of tillers per plant, 86% plant growth, 14% length of roots, 8% number of leaves and 50% dry matter content compared to control. Moreover, this plant has a very important nutritional value (0.8 UFL). Thus, this new introduced species could constitute an additional forage resource for Tunisia.
