Variation in micronutrient content of orange-fleshed sweetpotato varieties grown in different environments
Abstract

Field experiments were conducted at three locations in Zambia
to characterize 15 sweetpotato varieties for tuber yield and
micro-nutrient content. Location and variety had significant
effect on tuber yield. Marketable yield ranged from 5.22 -
9.69 t/ha with variety Kakamega recording the least yield.
AMMI analysis also indicated significant effects of genotype
and location for tuber yield. These accounted for 53 and 11%
of the differences. The variety x location effect was significant
for iron, but not zinc. Varieties Zambezi, K566632, 199062.1
and Mayai had high levels of β-carotene.
