Studying the effects of mycorrhiza and vermicompost fertilizers on the growth and physiological traits of Vetiver Grass (Chrysopogon zizanioides L.)

Effects of Salinity on Seedling Growth and Physiological Traits of Vetiver Grass (Vetiveria zizanioides Stapf)

Vetiver grass (Vetiveria zizanioides) is known to be survived under the diversesoil and water conditions. In order to study the effects of salinity stress on the seedlinggrowth of the desired species, a completely randomized design was conducted with 3replications. Seeds were sown in the salty-soil plots in the greenhouse. Salinity levels werespecified as 4 control ones including 20, 30 and 40 ...

Studying the quantitative and qualitative characteristics of vetiver grass (Chrysopogon zizanioides L.) under different compost and zeolite treatments

Nutritional and Antinutritional Components of Vetiver Grass (Chrysopogon zizanioides L. Roberty) at Different Stages of Growth

Vetiver grass was harvested at 4, 6 and 8-week old re-growth. The chemical composition and quantitative analyses of anti-nutritional components were determined. The result showed that dry matter and fiber content increased with age while crude protein, mineral content and anti-nutritional components reduced with age. It was concluded that age of re-growth significantly affect the nutrient and a...
