Explanation
(a) Method of propagating specimens J, K and Specimen J
- Specimen J(Yam tuber ): By seeds setts/mini setts/ whole yam tuber
- Specimen K (Plantain): By Suckers, Corms
- Specimen J (Tomato Fruit): By seeds
(b) 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/allow cut surface to dry under shade
