BLACK SOYBEAN RESPONSE TO ANTIOXIDANT APPLICATION FOR GROWTH AND YIELD UNDER SALINITY STRESS CONDITIONS

Black soybean (Glycine max L.) is native to Asia and well adapted tropical climate countries, such as, Indonesia. The demand for black supply increases due soy sauce making. Limited fertile land causes efforts enhance production relocate sub-optimal lands, saline land. However, in soils the plant productivity very low; therefore, technological inputs are required prevent crop from salinity stress, one of which an exogenous application antioxidants. presented study aimed analyze yield several cultivars when applied with antioxidants under stress conditions. used a randomized complete block design factorial arrangement three replications. first factor comprised four soybean, i.e., Malika, Detam 2, 3, 4, while second was (ascorbic acid, salicylic vitamin E – α-tocopherol) application, without antioxidant (control). results showed that significantly affected growth cultivars. cultivar 2 compared other cultivars, performed best based on morphological yield-related traits soil Furthermore, antioxidants, acid gave characters, ascorbic better traits. Overall, increased tolerance genotypes as control
