New book on scale appropriate equipment for conservation ag

We  are pleased to send you notice of the most recent output from the CIMMYT-Bangladesh team, a book on agricultural machineries made in Bangladesh that can be used for conservation agriculture and related production purposes. The details can be found below:


Krupnik, T.J., S. Santos Valle, A.J. McDonald, S. Justice, I. Hossain, and M.K. Gathala. 2013. Made in Bangladesh: Scale-appropriate machinery for agricultural resource conservation. Mexico, D.F.: CIMMYT.


ABSTRACT: An open-source publication targeted to machinery manufacturers, engineers, researchers and development practitioners, this book describes and provides technical designs for small-scale agricultural machinery developed or produced in Bangladesh to support the sustainable intensification of agriculture by smallholder farmers. The focus is on smart, scale-appropriate equipment — particularly for use with two-wheel hand tractors suited for the small plots typical throughout Bangladesh, but also in many countries where smallholder farmers predominate. Most of the machinery is designed for use with conservation agriculture crop management practices and allows precise and timely seeding and fertilization of crops with reduced soil disturbance. Each chapter includes written descriptions and photographs of the machines, outlining their purpose, performance and eld use, followed by detailed, to-scale technical designs and other information to facilitate production of standardized copies or improvements in the original designs. The implements described include zero tillage and strip tillage seed and fertilizer drills, bed planters, axial fow irrigation pumps, strip tillage blades, improved furrow openers and seed metering mechanisms – all specialized for use with two-wheel tractors.


We wish to graciously acknowledge USAID for funding the CSISA-MI project, the EU for funding the Agriculture, Nutrition and Extension Project, and ACIAR for funding the Rice-Maize project, all of which contributed to the development of this resource book.

Please note the following if you choose to download and print this book to aid in manufacturing agricultural machineries:


Different scales are used in the technical designs throughout the book, depending on what was most appropriate for the technical design and in accordance with the size of the paper used (some are on A3-sized paper, which is 29.7 x 32 cm, and others on A4, which is 21 x 29.7 cm). It is fundamental to understand that this allows the reader to take measurements directly from the paper since the design is scaled to the paper size. We recommend that you always use A3 size paper when printing the scaled technical designs, and/or be sure to print the technical designs on the same size of paper for each printing. The use of a different paper size than A3 will incur into measurement errors by not following these instructions.


We hope that you find the book useful!
