Maize/Annual forage legumes mixed cropping systems: Characterizing water and nitrogen dynamics in maize/vetch pure and mixed stands. 1. Procedures for collecting minimum data sets uri icon

abstract

  • 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. At the end of the document, a glossary of terms used in relation to phenology, etc., is presented to assist in identifying the different phases of crop growth and plant parts
