This data was created from a randomized study conducted using two on-station trials in order to evaluate the effects of soil nutrient management practice and living mulches on agronomic performance and yield of chili. Each of the trials was conducted in Siem Reap and Battambang differed in soil texture. The experiment was laid out in a split plot design consisting of living mulches as a main plot treatment and nutrient management as subplot treatments. Living mulch treatments were: Arachis pintoi, morning glory, rice straw mulch, and bare ground while nutrient management treatments were: inorganic fertilizer (UREA) only, cattle manure only, inorganic fertilizer 50% + cattle manure 50%, and control. Data was collected through three cropping seasons between 2018 and 2019. This dataset was collected through research of the project "Integrated Horticulture Livestock Systems" lead by Kansas State University, in partnership with the Royal University of Agriculture, the University of Battambang, and ADDA, as a part of the Feed the Future Innovation Lab for Horticulture.
