This work was carried out during summer seasons of 2008 and 2009 at El-Kassasin Horticultural Research Station, Hort. Res. Inst., Agric. Res. Center, Ismailia Governorate, to study the effect of foliar spray with Vitam. C, Vitam. B, and salicylic acid (SA) on nutrient uptake, photosynthetic pigments, dry weight and consequently, yield and quality of tuber roots of sweet potato grown in sandy soil. Spraying of sweet potato plants grown in sandy soil with Vitam. C and Vitam. B, at 100 ppm of each or with Vitam. C, Vitam. Bi and SA at 100 ppm of each increased N, P and K contents and uptake as well as total uptake by leaves and branches. Whereas, Vitam. C, Vitam. B, and SA at 100 ppm of each increased chlorophyll a, b,- total (a+b), as well as, carotenoids in leaf tissues, dry weight of leaves, branches and vine/ plant, reducing , non-reducing and total sugars, TSS, Vitam. C, carotene, starch and crude fiber content in tuber roots. Foliar spray with Vitam. C, Vitam. B, and SA in different combinations at 100 ppm of each, was the best treatment for enhancing total yield/fed. comparing with the foliar spray with Vitam C, Vitam. B, and SA each alone.
