Abstract:
This study compared over a 6-month period effects of tractor-
ploughing and hand-clearing seedbed preparation on
morphometric characteristics of three arid and semi-arid grass
species, namely;
Eragrostis superba
Peyr,
Cenchrus ciliaris
L
and
Enteropogon macrostachyus
(Hochst ex A Rich) Monro ex
Benth. Seedling mortality was significantly higher under hand-
clearing than tractor-ploughing. Tractor - ploughing also gave
better growth, and biomass yield.
