This document gives detailed step by step information on minium data sets collection procedures for the maize/vetch intercropping trial conducted at the Debre Zeit Expeiment Station in the Ethiopian highlands. Details are given on soil characterization, plot layout, initial condition soil sampling, periodic soil and plant sampling, procedures for separating plant samples into different plant components, and on methods of soil and plant analysis. Information is also provided on how to measure soil-water content, soil-water suction and some weather variables. Data recording sheets and/or forms have been included in the documents to make it easy to record the large amount of data to be collected in the execution of this work.
