Root starch content (Table 2)
Application of foliar fertilization, cultivars with foliar fertilization showed effect on root starch
content but cultivars did not effect. The treatment with Zn+Mg+S tended to give higher root starch
content as compared with all of application (28.51%) while HB 80 cultivar also gave higher root starch
content ( 27.16%). The HB 80 cultivar with Zn+Mg+S gave the highest by 29.33%.
