The effect of manure and ascorbic acid to the growth of Vetiveria zizanioides L. in saline soil

Abstract

Abstract Vetiveria zizanioides was known as vetiver that produces a good quality oil and is also competent in foreign markets. This study aims to determine the effect of manure and ascorbic acid on the growth of vetiver on saline soil by applying the appropriate dose of manure and ascorbic acid for optimal growth. The methodology was done using a randomized block design with three replicates and consisted of 2 factors, i.e., manure level (K) and the ascorbic acid concentration (A). The results suggested an interaction of the manure and ascorbic acid concentration in the plant height, root volume but not found in the number of clumps. The manure displays a significant response to plant height, number of leaves, number of clumps, and root volume. The ascorbic acid response to the growth was obtained to the best response in plant height, a number of leaves, and root volume. The dose of manure and ascorbic acid that increased concentration was suspected to control salinity stress. The manure was thought to be able to provide the organic matter in saline soil because the addition of organic matter holds water and retains nutrients. Besides, ascorbic acid has been a role antioxidant during plant stress.
