In the cultivar, KU 50 gave the highest fresh stem weight, HB 60 tended to give higher fresh root yield, while HB 80 tended to give higher root number per plant and root starch content.
In the foliar fertilizer treatment, T2= Zn+Mg+S gave the highest fresh stem weight and all so gave higher root starch content, T5)= Mg+S tended to give higher root number per plant and T3= Zn+Mg tended to give higher fresh root yield.
In the cultivar and foliar fertilizer treatment, HB 60 with Zn+Mg treatment gave the highest fresh root yield, while HB 80 with Zn+Mg+S treatment gave the highest root starch content.
