Abstract
Yields of sweet potato tips varied from 10 to 16 t/ha in weight and 61 to 352/m2 in number, whilst yields of marketable roots varied from 1 to 16 t/ha. Cultivar differences in dry matter, fibre, ash, vitamin B2 and oxalate were also observed. The tips appeared to provide an excellent source of vitamin B2 which is important for Asian diets deficient in this vitamin. Application of 120 kg N/ha gave higher tip yields than no nitrogen, primarily due to increases in their number and size. Among the leaf types evaluated, Kinangkong (a fine leaf cultivar) produced the highest yield, and had the highest amount of protein, lowest oxalate, and fairly high dry matter, which makes it a very desirable leafy vegetable.This publication has 1 reference indexed in Scilit:
