Noralyn B. Legaspi Lea C. Agbigay Christine Quiapo

Category: Project

Status: Extended

Duration: January 1, 2016 - December 31, 2022

Component Studies:

  1. Evaluation of Different Varieties/Accessions of Less-known Yam Species for Yield and Acceptability (Study 1)
  2. Development of Cultural Management Technology for the Increased Productivity of the Less-known Yam Species (Study 2)
  3. Enhancing the Economic Potentials of the Less-known Yam Species Through Product Development (Study 3)

Brief Description

Majority of the activities will be conducted on-station except on those which needed to be conducted on form or in other locations such as in the selection of promising accessions. Following are the different activities to be undertaken to satisfy the objectives of the project.

1. Evaluation of different varieties/accessions of less-known yam species (tugui and kamangeg) for yield and acceptability

a. Collection/assembly of materials

b. On-station evaluation and acceptability

c. On-farm evaluation of promising accessions

2. Development of cultural management technology for the increased productivity of the less-known yam species

a. Fertilizer application

b. Irrigation

c. Distance of planting

d. Use of different planting materials

e. Studies on backyard production of kamangeg

3. Enhancing the economic potentials of the less-known yam species (tugui, kamangeg, and karot) through food product development

a. Development of healthy food items using the less-known yam species

b. Standardization of processed tugui and kamangeg products

c. Shelf-life determination of processed tugui, kamangeg, and karot products

Expected Output

  1. High yielding varieties of tugui, kamangeg and karut acceptable to farmers and consumers.
  2. Production technology to increase the productivity of trugui, kamangeg and karot. 
  3. Technology for the utilization of the less known yam species.
