Learn how to grow root vegetables, some of the world's most vital crops!

Add to what you are already growing on your farm or start a new enterprise with this comprehensive course in root crop growing.

Root crops are the second most important staple crop in the world. They are an essential source of carbohydrates for people all over the world. They are also important food security crops for both humans and animals - as climate changes the agricultural environment, we will need to turn to resilient, carbohydrate and protein rich, easily grown crops to replace those that are highly dependent on water (e.g. rice) for their productivity and survival.

Root crops include:

  • potatoes
  • sweet potatoes
  • yams
  • turnips
  • carrots
  • swedes

In developing countries, some types of root crops (for example yams and cassava) which are relatively high in protein (about 6%), contribute to the diet as a substitute for other, less obtainable, protein foods such as fish or meat; root crops are also becoming very popular in the developed world as people begin to understand the benefits to their health and to the environment by growing and eating root vegetables.

This course will help you discover different varieties of root vegetables, learn best growing practices and understand different harvesting techniques.

Studies prove, time and again, that college-educated workers earn more than those with only a high school qualification. College graduates often enjoy additional benefits, including greater job opportunities and promotions. Though the proof for greater earning potential exists, some might wonder whether the cost of the education warrants the overall expense in the long run.

College Graduate vs. Non-Graduate Earnings

The National Centre for Education Statistics (NCES) analyses employee earnings data biennially, according to education level. Findings indicate that workers with a qualification earn significantly more than those without. Since the mid-1980s, education has played a large part in potential wages, with bachelor's degree holders taking home an average of 66% more than those with only a high school diploma do. While college-educated workers' wages have increased over the past two decades, those with only a high school education have seen decreases in annual salaries in the same time period (
