Effects Of Method Of Planting And The Length And Types Of Cuttings On Yield And Some Yield Components Of Cassava (manihot Esculenta Crantz) Grown In The Forest Zone Of Ghana
MetadataShow full item record
In two experiments carried out in 1970and 1971in the forest zone of Ghana, cuttings of cassava (Manihot esculenta Crantz cv. Ankra), with less than five nodes, produced lower yields per hectare and fewer and lighter tubers per plant than those with five or more nodes. The percentage take of cuttings was also lower in the shorter cuttings. In two other experiments in 1970 and 1971, three methods of planting: horizontal, slanting and vertical, and three types of cuttings: base, middle and top were used. The types of cuttings had no effect on yield or any other parameters tested. The methods of planting had no effects on yield and its components but they affected the depth and spread of tubers. Vertical planting produced deeper but more compactly arranged tubers while horizontal planting produced tubers which were shallower but more widespread. Slanting was intermediate for both depth and spread. It was concluded that cuttings from any part of the stem can be used. The cuttings must have at least five nodes and they should be planted vertically or slanting.
