Abstract

The study was conducted to characterize and evaluate the suitability of selected lowland rice areas in Nueva Ecija and Pangasinan and to determine possible climatic and land/soil constraints for rice production. Eight sites belonging to Maligaya series and San Manuel series were selected for the study. Suitability analysis indicated that climatic characteristics of the sites are moderately to highly suitable for lowland rice production while physical and chemical characteristics of the soils are , in general, highly suitable for rice production. Soil texture (sandy loam and loamy sand), soil pH (acidic and very acidic soil pH) and low levels of nitrogen and potassium were found to be the key constraints to lowland rice production. Grain yields in WS 2015 and DS 2015-2016 were generally higher in Nueva Ecija than in Pangasinan and yields were higher in DS 2015-2016 than in WS 2015. Farmers in Nueva Ecija apply higher rates of fertilizer particularly during DS. Provided that climate is unvarying and no strong typhoons would hit these areas during the growing season, yields are primarily influenced by farmer?s management practices, such as rate and timing of fertilizer application, rather than the physical and chemical characteristics of the sites.
