THE EFFECT OF CLONES AND PLANTING METHODS ON THE GROWTH AND PRODUCTION OF CASSAVA (Manihot esculenta Crantz)

Abstract

Cassava productivity can be improved through high-yielding clones and appropriate planting methods. This study aims to evaluate the effects of seven cassava clones (UK-1, Manggu, Garuda, SL-36, UJ-3, UJ-5, and Unila) and two planting methods (vertical vs. horizontal cuttings) on growth and yield components. The research was conducted at Rara Farm, Bandar Lampung, using a split-plot design with three replications. The results showed that the horizontal planting method significantly outperformed the vertical method in terms of the number of tubers, tuber dimensions, fresh tuber weight, bundle weight, harvest index, starch content, and starch weight. Significant clone-by-planting method interactions were observed across several yield variables. Clone UJ-5 consistently produced the highest starch content and weight. In conclusion, implementing the horizontal planting method and utilizing clone UJ-5 are highly recommended to optimize cassava production and starch quality.
