(a) ldentify specimens I and J.
Specimen I; Specimen J;
(b) To what group of forage does each belong?
(c) State four uses of specimen I and three uses of specimen J in agriculture.
(d) Mention four advantages of growing specimens I and J together.
Explanation
(a) ldentification of Specimens;
- Specimen I - Calopogonium mucunoldes / Pueraria / Centrosema spp.
- Specimen J - Northern Gamba (Andropogon gayanus)
(b) Group of forage crops to which they belong:
- Specimen I - Legume
- Specimen J - Grass
(c) Úses Specimen I - Calopogonium mucunoides / Puerarial /Centrosema spp.
- grazed or fed to livestock (livestock feed).
- used as cover crops.
- checking of soil erosion.
- supplies nitrogen to the soil.
- Can be used as green manure.
- can also be used as compost material.
Specimen J- Northern Gamba grass:
- Used as livestock feed,
- checks erosion,
- can be used as mulch,
- can be used for roofing purposes,
- used as compost material.,
- straw for bedding, used for roofing and for fencing.
(d) Advantages of planting/ combining the specimens I and J are: -
- combination serves as a source of balanced ration to ruminants.
- calopogonium/ puerarlal Centrosema sp will supply nitrogen to the soil thus, enriching the soil
- to aid the growth of the specimens.
- smoothering of weeds.,
- lmproves palatability of forage.
- combination makes more effective ground cover which prevents erosion and destruction of soil structure.
