Effect of salt stress on nutrients content in soil and leaves of three varieties sugarcane

Abstract The extension of the sugarcane cropping area in Indonesia is directed to saline soil, yet there still limited information about effect salt stress on commercial varieties sugarcane. A pot study was conducted at Indonesian Sweetener and Fiber Crops Research Institute greenhouse 2019. objective investigate salinity influences three varieties: growth, soil nutrient content, leaves. Treatments included (PS 881, PSJK 922, BL) with five different watering concentrations (0, 2000, 4000, 6000, 8000 ppm NaCl solution added). Results showed that decreased organic available K soil. Increasing concentration also reduced content N, K, ratio K/Na stalk diameter under stress. Among tested varieties, BL most susceptible relation reduction K/Na.
