  • Describe the storage, processing and sale of cereals used for livestock and demonstrate the calculation of some sample stock rations

Grain and Pulse Production Involves More Than Just Growing

Successful production of a grain crop starts with an ability to select an appropriate cultivar and know how to grow it and ends with knowing how to harvest, treat and store the grain once the crop has matured.

After Harvest the Next Step is Usually Drying

The crops discussed in this course are grown to produce either forage or grain. Forage is food for livestock, where the vegetative part of the plant itself is an important component of the crop. Grain, on the other hand, is the seeds from these crops used for human consumption. In this case, the grain is removed from the rest of the plant, then readied for eating. The type of consumption and amount of processing required varies according to the grain type and use.

A combine harvester is a machine that harvests grain crops and it usually combines three separate operations: reaping, threshing, and winnowing into a single process.

These processes can also be done by separate machines or by hand in smallholder farming systems. A thresher can also be a standalone piece of equipment on smaller farms without harvesters. It works by beating the plant to make the seeds fall out. Winnowing separates the loosened chaff from the grain, often by a process of lifting the grains up and allowing them to fall with a current of fair which carries away the lighter chaff allowing the heavier grain to fall downwards. Once winnowed, the grain can be dried and stored. It can then be processed when required.  When the grain reaches primary processing, the steps may vary some – rice, for instance, is often hulled then sold without milling.


Although crop regulations vary from country to country, drying is a government requirement in most places. This is because some level of drying is usually necessary for safe storage. Determining how much drying is required means the moisture content of the grain must first be assessed. This can be done by several methods ranging in their accuracy and cost:

  • Morphologically
  • With a moisture meter
  • With a simple drying test
  • Laboratory tests (NIR, Microwave)
