Scientific research is fundamental to advancing agricultural knowledge and addressing challenges faced by farmers, extension workers, and policy makers in Kenya. Preparing a scientific research proposal is a critical step that sets the foundation for successful investigation and innovation. This chapter guides agriculture and extension professionals through the essential concepts, types, and uses of research proposals, enabling them to design clear, feasible, and impactful studies that respond to local agricultural needs and development priorities.
A scientific research proposal is the written plan for a study, prepared before any data are collected. For an agriculture and extension professional it is the document that turns a question from the field, such as why yields are falling on a group of farms or why a new practice is not being taken up, into a study that can be carried out, checked and funded. A well-made proposal states the problem, the objectives, the method and the expected benefit, and it serves as a blueprint for the researcher and as a means of persuading funders, supervisors and farmers that the study is worth doing. This topic covers the terms used in a proposal and the main types of proposal.
Research has its own precise vocabulary. Using the terms correctly prevents confusion between the researcher, the people reviewing the proposal and the farmers who take part.
Scientific research is the systematic collection and study of evidence, using a planned method, to answer a question or solve a problem. It differs from opinion because the method can be repeated and the results can be checked. Comparing two feed rations on matched groups of animals over a set period is scientific research, while a general impression of which feed seems better is not.
A research proposal is a structured document that outlines the plan for conducting a scientific study. It describes the problem, objectives, method, resources, timeline and significance of the study, and it guides the researcher and informs the people who review or fund it.
The research problem is the specific issue or gap in knowledge that the study sets out to address. In agriculture it could be declining yield of a crop, a pest that spreads in stored grain or a poor take-up of an advised practice among livestock keepers.
A research question is the problem written as a question that the study will answer, for example, "Does mulching raise the yield of kale grown by small-scale growers?"
A hypothesis is a testable statement about the expected result, which the study will support or reject. For example, "Plots mulched with dry grass give a higher kale yield than unmulched plots."
Research objectives are clear, measurable statements of what the study intends to achieve. They guide the design of the study and are used afterwards to judge whether it succeeded.
The methodology is the set of procedures, techniques and tools that will be used to collect and analyse data. A study might use a questionnaire, a field experiment or discussions with farmer groups.
The significance is the anticipated benefit of the study to knowledge, policy or practice, such as better crop management or improved advice to farmers.
Proposals are named after the kind of study they plan. A proposal for a study that counts and measures looks different from one that listens to farmers' accounts, and the type chosen affects the questions asked, the methods used and the way results are reported. Four types are described below, and they can be combined when a study needs both numbers and explanations.
A descriptive research proposal plans a study that describes the characteristics of a group, place or practice as they are, without changing anything. It answers questions beginning with what, how many and how often. For example, it could document the feed types used and the milk yields on dairy farms in an area, or the share of tomato growers who use a particular nursery practice.
A quantitative research proposal plans a study that collects numerical data and analyses it with statistics. It is used to measure, compare and test relationships, and it usually states a hypothesis. For example, a proposal may plan a field trial that compares maize grain yield from plots sown at three different spacings, with each spacing repeated on several plots and the grain weighed in kilograms at harvest.
A qualitative research proposal plans a study that collects non-numerical information such as words, stories and observations, to understand the views, reasons and experiences of people. It is used when the reasons behind a practice are not yet known. For example, it could plan group discussions with farmers to find out why many of them do not use improved poultry housing, although they know about it.
A case study proposal plans an in-depth study of one case, or a few, such as a single farm, a farmer group, a nursery or one project, studied in its real setting. It looks at many aspects of the case together and uses several sources of evidence. For example, a proposal might plan a study of one farm that has installed a rainwater harvesting system, following costs, water use, crop performance and the owner's experience over a season.

It highlighted the various uses of research proposals in guiding investigations and securing approval or funding. The process of identifying a research problem was examined as a critical first step in proposal development, followed by the formulation of clear and focused research objectives. Attention was given to designing appropriate data collection methods, including questionnaires, interviews, experiments, surveys, and observation, each suited to different research aims. The chapter also detailed the essential structure of a research proposal, covering components from the cover page and abstract through to the introduction, literature review, methodology, summary, conclusion, and recommendations. Understanding these elements equips researchers to prepare comprehensive and coherent proposals that effectively communicate their intended study.
