Question 3

(a) State one method of propagating each of specimens J, K and L on the farm. [3 marks]

(b) Describe briefly the method of planting each of specimens J, K and L. [ 12 marks]

This question was poorly attempted by the candidates. In question 3(a), majority of the candidates were unable to state the method of propagating each of specimens J(yam tuber), K (plantain) and L(tomato fruit). Also in question 3(b), majority of the candidates could not describe briefly the method of planting each of the specimens (i.e yam tuber, plantain and tomato fruit).

The expected answer include:

Method of propagating specimens J, K, and L

Specimen J(yam tuber)

- By seed yams/yam setts/mini setts/whole yam tuber

Specimen K (plantain)

- By Suckers, Corms

Specimen L (tomato fruit)

- By seeds

Method of planting specimens J,K and L.

Specimen J(yam)

Yam tubers are cut into setts
Yam setts/seed yams are treated with an insecticide/or wood ash before planting/allowcut surface to dry under shade
Make hole on the ridge/mound/in the ground
Place a yam sett or seed yam into the planting hole at a slanting angle with cut end up
Yam setts/seed yams are planted at a spacing of 1m x 1m
Cover the hole with soil
Mulch with dry grass
Provide stakes

Specimen K (plantain)

Dig holes about 60cm x 60 cm x 60 cm
Fill the holes with a mixture of top soil and organic manure
Place a sucker in each hole
Cover the root part with soil
The suckers are planted at a spacing of 4m x 4m
Mulch planted suckers at the bases

Specimen L (tomato)

Sow seeds in nursery beds or boxes - under shade
Water regularly
Transplant seedlings into the field after 4 - 6 weeks or when the seedlings are at three-
leaf stage
Seedlings are planted at a spacing of 60cm x 60 cm or 90 cm x 40 cm
Transplant seedlings usually in the mornings or evenings
Water seedlings daily
Mulch seedlings
Provide stakes
