Nutrient content and yield of upland kangkong (pomea Aquatica Forssk) grown in different growing media. 2003 Upland kangkong (Ipomea aquatica Forssk) was grown in styropropylene boxes to determine the effects of the different production systems--garden soil (Gs, control), garden soil plus ammonium phosphate and urea (GsAU), Gs with vermicompost and carbonized rice hull (GsVC), and hydroponics SNAP solution (Hss) on the nutrient content and yield of upland kangkong. Proximate composition did not differ. Calcium was higher in Gs and GsAU. Iron content in Hs and GsVC was higher than GS, though both did not differ with GsAU. Iron content in GAU and Gs-grown did not vary. Vitamins A and C, did not differ across treatments. With reference to the Recommended Nutrient Intake for Filipinos (RNI), kangkong, irrespective of production system, is rich in Fe, vitamin A and vitamin C, wherein Hss, GsVC and GsVC as well as Gs obtained the highest percentage, respectively. Calcium and Zn were less than 15% while Mg, P, energy and protein were less than 10% of the RNI. The upland kangkong grown in sC obtained higher yield. It did not vary with GsAU. Hydroponics-growth had lower yield than GsVC and GsAU while Gs obtained the lowest. Kangkong (water spinach) Plant nutrients Hurtada, W. A. Barba, C. V. C. Dizon, E. I. Maghirang, M. V.
