Field evaluation of selected yam (Dioscorea (data) accessions in acid soils and saline-prone areas

摘要

In the context of agricultural problem soils, salinity and acidity dominate the problems related to agricultural landuse. This study was conceptualized to determine the possibility of utilizing some problem soils into yam production. Selected yam accessions were assessed for their performance in acid soils and saline-prone areas. The accessions planted in the saline-prone area, a Balongay clay at Sta. Teresita, Canaman, Camarines Sur, Philippines were Accession 5, Accession 6, Accession 8, Accession9, 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. Accession 6 and 10 were both economically viable in saline-prone areas and acid soils as shown by the highest return on investment compared with other treatments.
