Abstract


Sweet potatoes are a local food source with the potential to support food diversification in Indonesia, primarily due to their carbohydrate, vitamin, and mineral content. However, national sweet potato productivity continues to fluctuate due to reduced harvested area. One method to increase yields is by providing stakes. Stakes help plants grow vertically, thus optimizing sunlight absorption. This study aimed to determine the effect of staking on the yield of Thai sweet potato cultivars. This study was conducted in Sigerongan Village, Lingsar District, West Lombok, from August to December 2024 using a non-factorial Completely Randomized Design (CRD) with two levels: with and without stakes, with nine replications each. The parameters observed were stem length, number of leaves, number of tubers, tuber weight, tuber diameter, tuber length, and the percentage of marketable tubers. The results showed that the staking treatment had a significant effect on stem length and tuber weight with an average of 821.22 g, higher than the treatment without stakes, while the parameters of the number of leaves, number of tubers, tuber diameter, tuber length and percentage of marketable tubers showed non-significant results. The conclusion of this study is that the staking treatment can increase growth in the stem length parameter by 51.5%, while in the tuber weight parameter, the provision of stakes can increase the weight of the tuber spread by 13.56%.
