This dataset is a result of a study that was carried out in nine on-farm sites of Central and Southern Malawi to understand and compare the effects of different cropping systems (conservation agriculture (CA) and conventional) on soil physical and chemical parameters and long-term maize productivity. Six experiments were established in each target community. Each experiment had three treatments at one farm and was treated as a replicate, plot sizes were 0.1 ha per treatment. The treatments were as follows: <ol>1. Conventional control plot consisting of the traditional ridge and furrow land preparation planted with continuous monocrop maize (CPM). The residues were managed using methods commonly practiced in each extension planning area; i.e., the residues were incorporated into the ridges. Continuous monocrop maize was planted on the ridges.</ol> <ol>2. CA plot with continuous monocrop maize (CAM) planted into the previous years’ ridges (where they still existed) or directly into the plot without previous ridge formation. Crop residues from the previous years’ harvests were retained as a surface mulch. Maize seeds were planted as sole crops in no-till methods using a pointed stick (dibble stick).</ol> <ol>3. CA plot with maize intercropped with a legume [cowpea or pigeon pea or groundnut. Both crops were planted with the dibble stick into the previous years’ ridges (where they still existed) or directly into the plot without further ridging. Crop residues were retained as surface mulch as in treatment 2.</ol>

<h3>IFPRI Datasets Terms of Use Statement</h3> <h4>(December 2019)</h4> <p> <strong>1. Description </strong></p> <p>The International Food Policy Research Institute (IFPRI) views the products of its research including research dataset(s) as global public goods and is committed to enabling their widespread distribution and use by providing unrestricted public access. This is in keeping with the <a href="https://www.ifpri.org/cdmref/p15738coll2/id/133308/filename/133517.pdf">IFPRI Research Data Management and Open Access (RDMOA) Policy</a> and the <a href="https://cgspace.cgiar.org/bitstream/handle/10947/4488/Open%20Access%20Data%20Management%20Policy.pdf?sequence=1&isAllowed=y">CGIAR Open Access and Data Management Policy </a> (each, a “Policy” and together, the “Policies”).</p> <p>IFPRI makes all its research data publicly available through the “IFPRI Dataverse.” The IFPRI Dataverse houses and is comprised of datasets collected during the course of IFPRI research, including data tables in various standard formats, survey instruments, codebooks, metadata, and other associated documentation. IFPRI Dataverse is a network member of Harvard Dataverse, which is a repository for research data hosted at <a href="https://dataverse.harvard.edu/">Institute for Quantitative Social Science (IQSS)</a>, Harvard University.</p> <p>IFPRI is the owner of the “IFPRI Dataverse” (sometimes referred to in these Terms of Use as the “Site”).
