“…The growing media composition is one factor that influences growth characteristics, including plant height and the number of leaves. Research by Carvajal et al (2023) showed that N, P, K, Ca, Mg, and S greatly affected plant height and the number of leaves because the omission of minerals treatment reduced plant height and the number of leaves by around 29% and 66.7%, respectively. Based on Howeler (2017), the range of media composition that can be used for cassava growth in nutrient solution cultures consists of 80 ppm N in Ca(NO3)2.4H2O, 4 ppm P in NaH2PO4.2H2O, 40 ppm K in K2SO, 57, 25 ppm Ca, 20 ppm Mg in MgSO4.7H2O, and 42.97 ppm S, and 0.1 ppm Mn in MnSO4.4H2O, 0.05 ppm Mo in Na2MoO4.2H2O, 0.2 ppm B in H3BO3, 0, 1 ppm Zn in ZnSO4.7H2O, 0.05 ppm Cu in CuSO4.5H2O, and 2 ppm Fe in FeCl3.6H2O.…”
