Abstract:
Background: Cassava (Manihot esculenta Crantz) is a source of carbohydrate among the population after maize and rice and
highly contributes to food security and livelihood to majority of small scale farmers in Sri Lanka as well as in African continent. The
production of these starchy plants is declining due to the problem of low yield, high labor cost, pest and diseases damage and
shortage of land. However among the yield limiting factors of cassava, the planting method of stem cuttings which depend on plant
cultivar and environmental conditions. Therefore, the present study was carried out to reveal information on the effect of planting
methods on the growth and yield attributes of cassava.
Methods: The field experiment was conducted at the Farmer’s field in the Batticaloa and laboratory experiment was led in South
Eastern University of Sri Lanka which is located in Sri Lanka. The field trail was carried out over a period of four months during from
May to September in 2018. The treatments used were three planting positions (Angled, vertical and horizontal) and two cultivars (“cv.
Local” and “cv Kirikawadi”) were combined in factorial arrangement and laid out in randomized complete block design with three
replications.
Result: The result revealed that root yield was significantly (P < 0.05) affected by the interaction effects of the planting position and
varieties. Significant differences were observed among planting methods in all tested variables. Based on the study, storage roots
yield of cassava could be enhanced by planting method of angled position.
