Study Grain Crop Production - cereals, pulses and pseudocereals

Grain crops are are grown to produce seeds for human or animal consumption. Cereals are the most common grain crops (produced from grasses). Others include pseudocereals.

Crops are grown under a wide variety of different climatic and soil conditions. For success though, it is important to match the conditions with the type of grain grown.

Large scale production of grains is carried out around the world on very large farms, with a high degree of mechanisation. Much of the world's staple foods are produced this way. This is by no means the only way grains can be grown.

In this course, you'll learn about:

  • the right time to harvest
  • growth cycles
  • storage
  • how to provide adequate soil nutrition
  • seed bed preparation

Note: Some seed crops may also be processed to produce oils. This course largely excludes crops that are grown primarily for oil production.

WHY DO WE GROW GRAIN CROPS?

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.

Reaping is the physical cutting of the crop. In harvesters, usually the crop is gathered in by the header at the front of the harvester and a slowly rotating wheel (pickup-reel) pushes the crops down towards the cutter bar. This often has teeth which open/close repeatedly to cut the crop off at the base. The cut crops are fed to the centre by spinning augers and travel up a conveyor. A thresher (drum) beats the crops to break them and the grain is shaken off; the grain then falls through sieves into a collecting tank (winnowing) and the chaff is released through the back of the machine by a spreader or it can be baled up.   

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.

 

WHO IS THIS COURSE FOR?

Obviously anyone who manages or works on a farm that grows grain can benefit from this course.  It can also benefit others who work in support of the grain industry. 

Businesses that supply goods or services to the grain industry will benefit by having a deeper understanding of how grain is grown and harvested. Anyone who studies, teaches, researches or  writes about farming may need to deepen or broaden their understanding of grain production, and for such people, this course can be ideal for professional development.
