Our impact The difference we make The difference we make We have recently received data from 11 farmers who had agreed last year to prepare DBF on a plot adjacent to a plot where they continued with the traditional farming method. The tilling and planting done was identical, as well as the application of mulch and fertiliser. This was overseen by our Monitoring and Evaluation Officer (fully funded by The Fore) to ensure identical treatments. We passed this data to a well-known international statistician and the chart of the results are shown on the next page. This is our own research, following years of hearing from farmers by word of mouth, how their yields have risen. The extent is remarkable after only 1 year and we expect the yield gap to widen further each year. YIELD CHARTS 11 sample farmers planted maize using the two methods for comparison; the treatment of both crops was otherwise identical. Despite the small size of the sample and possible bias, the data demonstrates that the DBF method yields significantly more than the Ridge method. The data suggest that from 10,000 Tiyeni farmers, the majority would have seen a gain of more than 60% from using the Deep Bed method. Table one, below, is in the order of the original data. Table two, below, is ordered according to the yields achieved using the Ridge method (largest to smallest): the first two saw only a modest gain; the next five showed strong gains; three of the last four doubled their yield; and one farmer may have had some kind of problem with the Deep Bed method.
