Grain Broadcaster Utilization in Conservation Agriculture

The objective of this course is to give students initial insights into the use of a grain broadcaster, emphasizing it specifications and main parts.

This kind of grain broadcaster has recently been introduced to Cambodia and is solely used by the Conservation Agriculture Service Center (CASC), which belongs to the Department of Agricultural Land Resources Management (DALRM), General Directorate of Agriculture (GDA). The CASC team is involved in the design and assessment of direct seeding mulch-based cropping (DMC) systems in different agro-ecoregions. DMC is mainly developed for rainfed lowland rice, irrigated rice, and annual upland crops (i.e., cassava, maize, soybean, and others pulse crops). A large diversity of cover/relay crops are used within DMC systems. To learn more about the main principles of DMC systems, please follow the link.

Conservation Agriculture (CA) is an approach to managing agro-ecosystems for improved and sustained productivity, increased profits and food security, while preserving and enhancing the resource base and the environment (FAO, 2013). As we have known, grain broadcasters help reduce farmers labor force in farming.

At the end of this lesson, you will be able to:

  • To introduce all main parts of the grain broadcaster.
  • To provide guidelines for adjustment and setup of broadcaster.
  • To overview maintenance and repair of grain broadcaster.
