WEEK TWO
FACTOR AFFECTING THE PRODUCTIVITY OF PASTURES
- Persistence: ability to survive and spread by vegetative means.
- Aggressiveness: ability to compete favourably with other weeds.
- Resistance to trampling.
- Seed viability or profuseness or ease of propagation.
- Resistance to drought.
- Absence of pest and diseases.
- Good management.
- Adequate stocking.
ESTABLISHMENT OF PASTURES
Before pasture can be established, the following factors should be considered
- Adaptation of species
- Palatability
- compatibility
- time of maturity: should be short
- lifestyle of the species
STEPS IN ESTABLISHING A PASTURE
- Site selection.
- Clearing of land.
- Removal of debris
- Cultivation of site (land preparation).
- Planting of pasture crop.
- Supplying.
- Promotion of tillers (more point of growth).
- Weeding.
- Fertilizer application.
- Irrigation.
- Pad docking.
MANAGEMENT PRACTICES IN PASTURE
- Burning (when forage becomes fibrous to ensure regrowth of lush forage).
- Fencing to discourage overgrazing or facilitate rotational grazing.
- Fertilizer application or manuring.
- Regular weed control.
- Adequate pest and disease control.
- Irrigation.
- Adequate stocking.
