Question

Describe deviation farmer experiment ?

Answer 1

In alley farming research projects, it is highly desirable to initiate on-farm research activities as early as possible. Naturally, before alley farming experiments can move on-farm, a certain amount of time will be devoted to purely on-station research. This is necessary for screening and evaluation of multipurpose trees, and for experimentation with management practices. However, AFNETA's strategy is for collaborating institutions to begin on-farm work as soon as researchers have found a "best-bet" prototype for local agroecological conditions.
This unit begins by defining on-farm research (OFR) and explaining the important role of OFR in the testing and development of alley farming systems. It then describes the various types of OFR which alley farming research projects may entail. Detailed methodological guidelines and experimental designs are not provided here, but may be found in the Annex and in Volume 2.
As part of AFNETA's Core Course in Alley Farming, this unit restricts its coverage to experimental and developmental OFR. These are the types of OFR that are directly involved in alley farming research projects such as those supported by AFNETA. However, it is assumed that researchers have conducted on-farm surveys at an earlier stage. Such diagnostic on-farm work is necessary to demonstrate the potential relevance of alley farming in the local area. For example, a station or a ministry may have found through on-farm surveys that local farmers face constraints such as declining soil fertility, soil erosion, poor livestock nutrition, and/or land scarcity. Such findings would justify research into alley farming or other technologies that could address the constraints.
The pre-experimental type of on-farm activity is covered in the technical papers on Diagnosis and Design methods and socio-economic surveying
