Sažetak
The nutritional value of the sweet potato leaves has recently been emphasised as their anti-oxidant and phenolic compounds can offer improved human health and nutritional benefits. This has increased the awareness of the food industry and consumers in using sweet potato greens as a functional food. To increase the level of phenolic compounds in sweet potato leaves, we studied the influence of potassium (K) fertilisation at different N-K ratios [1:1 (control), 1:2.5, or 1:5] on the phenolic content and corresponding anti-oxidant activity of two different cultivars of sweet potato, ‘Bat1’and ‘Boniato’. In general, enhanced K fertilisation increased the level of phenolic compounds and the corresponding anti-oxidant activity. However, the two cultivars differed in their response. Phenolic acids were only increased in ‘Bat1’ after the application at N:K ratio of 1:5 (approx. 20% ), while enhanced K fertilisation at all rates increased the flavonoid content of both cultivars (approx. 300% ). Our results could be useful for sweet potato producers wishing to make informed decisions on which cultivar and/or mineral fertilizer regime to choose in order to produce sweet potato leaves of the desired nutritional quality.
