Abstract

Cassava is an important food crop commodity in Indonesia after rice, corn, soybeans, peanuts and green beans. When planting cassava, there are disease attacks caused by fungi, one of which is the Fusarium oxysporum fungus. One alternative method that can be done is by inducing salicylic acid in cassava (Manihot esculenta Crantz) to make it resistant to fungal attacks. This research aims to determine the resistance of cassava plants to the Fusarium oxysporum fungus. The method that will be used is a Completely Randomized Design (RAL) with 5 levels of salicylic acid concentration, namely 0 ppm, 80 ppm, 100 ppm, 120 ppm and 140 ppm with 5 replications. Observation data consists of number of leaves, number of shoots, and root length. Analyzed using analysis of variance (ANOVA) at a real level of 5% and further tested with the BNT test (Least Significant Difference) at a real level of 5%. The effective concentration for cassava plants infected with the fungus Fusarium oxysporum is a concentration of 100 ppm.Keywords: Cassava, Salicylic Acid, Fusarium oxysporum.

Abstract

Cassava (Manihot esculenta Crantz) is a plant that is widely cultivated in Indonesia, this is because cassava is one of the staple food sources and sources of income throughout the tropics, but in the planting process, farmers are often constrained by attacks by pathogenic fungi that cause fusarium wilt disease and cause the quality of cassava plants to decline. One way to control this disease is by selecting cassava plants in the planting medium in vivo through salicylic acid infiltration to increase resistance to pathogens and improve the quality of cassava plants. The purpose of this study was to determine the effect of salicylic acid on the number of leaves, leaf stomatal index, and phenol content of cassava plants resistant to Fusarium oxysporum compared to controls. This study used a one-factor Completely Randomized Design (CRD) with 5 levels of salicylic acid concentration, namely 0 ppm, 80 ppm, 100 ppm, 120 ppm and 140 ppm. Data analysis using Analysis of Variance (ANOVA) and further testing with Tukey test at the 5% level. The results showed that the concentration of salicylic acid that was tolerant for cassava plant selection with optimum growth was 100 ppm which was indicated by an increase in the number of leaves and leaf stomata index while the most optimum concentration of salicylic acid for increasing phenol levels was 140 ppm Keywords: salicylic acid, cassava, Fusarium oxysporum, induced resistance
