  • Bed planters for service providers: experiential learning modules for sustainable intensification and agricultural service provision
    (CIMMYT, 2020) Krupnik, T.J.; Naher, K.; Islam, S.; Matin, Md. A.; Huq, S.M.; Begum S.A.; Hoque, M.A.; Nazim Uddin, S. Md.; Justice, S.; Khondker, M.E.J.; Hossain, I.
    This set of training modules focuses on ensuring that service providers are able to make repairs to bed planters efficiently and correctly. It builds on other books in this series, and is designed so that anybody who uses these materials can easily conduct training – even those with a limited background in and understanding of agricultural engineering or machinery. By the conclusion of the training module (which can be completed in a single day of intensive training or in a multi-day, multi-session format), participant service providers will be well equipped to repair bed planters as part of their ongoing agricultural machinery service business. However, users of this book should carefully read all the instructions on how to implement the training effectively in order to ensure the best learning experience possible for the participants. A key aspect of this is ensuring that the training is experiential and interactive, as discussed in the next section.

  • Power tiller-operated seeders for mechanics: experiential learning modules for sustainable intensification and agricultural service provision
    (CIMMYT, 2020) Krupnik, T.J.; Naher, K.; Islam, S.; Matin, Md. A.; Huq, S.M.; Begum S.A.; Hoque, M.A.; Nazim Uddin, S. Md.; Justice, S.; Khondker, M.E.J.; Hossain, I.
    Mechanical sowing refers to the placement of seeds into the soil by an agricultural machine or manually operated (but mechanical) device. Mechanical sowing, also referred to as mechanical seeding, is generally practiced in areas where there are constraints to labor availability or where farmers want to reduce the drudgery of planting seed by hand. It is typically utilized for cereal crops, but can also be applied to legumes and many other crops, including rice. When farmers or agricultural machinery service providers – people who own seeding machinery and rent out its use on an affordable fee-for-service basis – practice such seeding, the geometry of crop placement tends to be precise, so long as the machine is well calibrated, and correctly used and maintained (topics that are covered in this learning module). While mechanical seeding may not always result in increased yields, it does tend to save labor costs for farmers, and thus profit increases where yields are maintained compared to hand-sown seed. Further savings may result when farmers use mechanical seeding equipment that tills or prepares the soil at the same time as it sows seed, or where tillage is foregone, as in zero-till and conservation agriculture systems. Where the sowing date is critically important – for example, for wheat or maize grown in the tropics and sub-tropics – mechanical seeding can advance sowing dates, leading to potential yield increases compared to more time-consuming conventional planting involving multiple tillage passes and hand sowing. This book focuses on seeding machinery that can be attached to a two-wheeled tractor (sometimes called a ‘power tiller-operated seeder’, or PTOS), which typically has a rotovator to till the soil, and seed and fertilizer boxes with mechanisms to meter and place the seed and fertilizer into the soil in rows as the tractor moves forward. Other configurations exist, but we focus on the above because it tends to be the most commonly and commercially available seeding machine in South Asia, Southeast Asia and parts of Africa. More specifically, our focus is on two-wheeled ‘hand’ tractors (sometimes also called single-axle tractors) because of their wide suitability for smallholder farming conditions in both Asia and Africa, although they are also found in parts of Central and South America. The ‘scale-appropriate’ nature of this equipment for resource-constrained smallholder farmers is particularly appealing for agricultural development projects concerned with advancing appropriate technologies.

  • Self-propelled multi-crop reaper for mechanics: experiential learning modules for sustainable intensification and agricultural service provision
    (CIMMYT, 2020) Krupnik, T.J.; Naher, K.; Islam, S.; Matin, Md. A.; Huq, S.M.; Begum S.A.; Hoque, M.A.; Nazim Uddin, S. Md.; Justice, S.; Khondker, M.E.J.; Hossain, I.
    The self-propelled multi-crop reaper is an innovative machine suitable for smallholder farmers growing small- and medium-grain crops like rice, wheat and barley. It can facilitate rapid and low-cost harvesting, and is of particular interest in areas where farmers lack sufficient labor or need to clear fields rapidly so they can replant the next crop. Its small size and ease of operation and movement makes it ideal for many farmers in South Asia, Southeast Asia and sub-Saharan Africa. The self-propelled multi-crop reaper increases reaping efficiency, from 225 or more hours per hectare when manual labor is used, to about five hours per hectare. In South Asia in particular, where rice-wheat cropping systems are dominant, late rice harvesting also sets back dry season planting, and can cause large yield losses for the subsequent crop – for example, up to 57 kg per hectare lost per day when wheat is late planted. Use of the multi-crop reaper can thus save farmers time and money, and accelerate the turnaround time between crops. This set of training modules focuses on ensuring that mechanics are able to make repairs efficiently and correctly to self-propelled multi-crop reapers. It builds on other books in this series, and is designed so that anybody who uses these materials can easily conduct training – even those with limited background and understanding of agricultural engineering or machinery. By the conclusion of the training module (which can be completed in a single day of intensive training, or in a multi-day, multi-session format), participant mechanics will be well-equipped to repair self-propelled multi-crop reapers as part of their ongoing agricultural machinery servicing business. However, users of this book should carefully read all instructions on how to implement the training effectively in order to ensure the best learning experience possible for participants.

  • Axial flow pumps and mixed flow pumps for mechanics: experiential learning modules for sustainable intensification and agricultural service provision
    (CIMMYT, 2020) Krupnik, T.J.; Naher, K.; Islam, S.; Matin, Md. A.; Huq, S.M.; Begum S.A.; Hoque, M.A.; Nazim Uddin, S. Md.; Justice, S.; Khondker, M.E.J.; Hossain, I.

However, users of this book should carefully read all the instructions on how to implement the training effectively in order to ensure the best learning experience possible for the participants. A key aspect of this is ensuring that the training is experiential and interactive, as discussed in the next section. This training uses an experiential and hands-on modular format. It is based on a foundation of experiential and hands-on work, combined with discussion and reflection among participants. This means that although the facilitator is instructed on how to carry out the training and how to present materials, the format in which this is done should be horizontal and participatory, with room for adaptation and modification. We also underscore that farmers and agricultural machinery service providers – who are the target of this training – are experts in their own fields. They work daily on farms and have considerably more experience than most university educated technicians, researchers or extension agents. Attentively listening to their opinions and working with them to respond to their needs and experiences will facilitate improved learning and enhance the quality of any given training session. In this sense, it is the responsibility of the training facilitator to elicit the participants’ input, opinions and ideas, and to use these interactively to shape discussion and learning. Each facilitator therefore should think of him or herself as a guide whose goal is to elicit insight and ideas from the trainees, in order to enhance their learning process. The technical materials included in this document should therefore be seen as a guide to supplement the in-depth knowledge that the trainee farmers and agricultural machinery service providers already have.
