'Lagikway' is an underutilized vegetable in the Philippines. One of the reasons for its low utilization is the lack of information in terms of production and nutritional quality under Philippine conditions. Hence, yield trial and nutritional quality evaluation were conducted from June 2017 to February 2018 involving three lagikway entries including RXII 13-003, RXII 13- 019, and Lag 152649. The effect of blanching on the phytochemicals of leaves for consumption was also determined. Lagikway rooted cuttings were transplanted in 5 m x 1 m plots with 50 cm x 50 cm distance, and the experiment was carried out in a randomized complete block design (RCBD) with four replications. Young leaves and shoots considered for consumption were harvested 1 mo after transplanting (MAT) and continued at 2-wk intervals. Data revealed that potential yield is at 24.5 tons/ha for RXII 13-003, 21.36 tons/ha for RXII 13-019, and 21.94 tons/ha for Lag 152649. For proximate analysis, the moisture content is highest in RXII 13-019, the fat content is highest in RXII 13-003, and the protein content and the nitrogen-free extract are highest in Lag 152649. Ash and fiber content were the same from all the three lagikway accessions. Significant differences were also observed on the different lagikway accessions in terms of phytochemicals and antioxidant activity, and blanching had greatly affected these parameters. Lag 152649 had the highest phenolics, flavonoids, tannins, and radical scavenging activity (RSA). Hence, Lag 152649 will be recommended for mass propagation and distribution, which will eventually lead to further promotion and utilization of this underutilized vegetable.
