In the context of agricultural problem soils, salinity and acidity dominate the problems related to agricultural land use. This study was conceptualize to determine the possibility of utilizing some problem soils (location specific) into yam production so that, lands without constraints for crop production could be utilized for other high value crops and provide information about the yield of yam in these areas. Saline-prone areas and acidic soils could be converted into productive agricultural lands considering the necessary information with regards to soil and water management for these problem soils. The information generated could help farmers with problem soils to increase their income through yam production. This could answer the goals and objectives of the Department of Agriculture which are food security, poverty alleviation, improved productivity and increased income, resource sustainability and global competitiveness. Selected yam accessions were assessed for their performance in acid soils and saline-prone areas. The accessions planted in the saline-prone area, a Balangay clay at Sta. Teresita, Canaman, Camarines Sur [Philippines] were Accession 5, Accession 6, Accession 8, Accession 9, Accession 10 and Accession 12, while the Accession 6, Accession 10, Accession 11, Accession 12, Accession 13 and Accession 21 in an acid soil, a Caroyroyan clay loam at Pacol, Naga City [Philippines]. This was conducted using Randomized Complete Block Design (RCBD) with three replications. Results revealed that in saline-prone areas and in acid soils, planting of yam would be beneficial to farmers. Accessions 6 and 10 were both economically viable as shown by the highest return on investment compared with other treatments.
