Fertilizer in small doses yields higher returns for less money

pacities of agrodealers and by difficulty in projecting fertilizer demand, which varies with rainfall.

"We also need to work on extending training to underserved areas and to train extension personnel in low-rainfall areas," he said. "Female-headed households were significantly less likely to adopt microdosing than others, possibly reflecting labor shortages or difficulties accessing fertilizer. Understanding the particular constraints that female farmers face and adapting the methods or the training to their circumstances could also help extend adoption of the technique."

The research data were collected via a structured household survey in eight districts in semi-arid areas with additional information about fertilizer availability and demand from key informant interviews with local extension service providers, non-governmental organizations, and agrodealers. Focus group discussions were also utilized. The household survey included questions about assets, cropping patterns, agricultural production, training in microdosing, extension techniques, and fertilizer use and adoption, with particular attention paid to management practices and output on cereal plots two previous cropping seasons.

"What was particularly encouraging from the data is that, when comparing the costs of research, development, and promotion of microdosing in Zimbabwe to the gains achieved through a 30 percent adoption rate and an estimated productivity effect, the data suggest an internal rate of return on the investment in microdosing of over 40 percent," Winter-Nelson said. "And that's a good motivation to continue to try to get more farmers in Zimbabwe to try microdosing."
