Vegetable Crops - definition
Webster’s definition of vegetable
“A herbaceous plant cultivated for food, the edible part or parts of such plants”
Vegetable Crops - definition
Are Not:Cereal cropsSugar cropsPulse cropsWoody fruit crops
Are:Almost everything else90+ economically important crops of various types and species
Vegetable Crops – other features
Generally cultured as annuals
Mostly propagated from seed
Many are insect pollinated
Highly variable in climate and environment
Most require intensive management
Production acreage is usually small
All are very important in the human diet
Vegetable Crops – PlSc 451/551
WHY are we studying vegetable crops?
Because they are critical to betterment of the human condition
Nutrition
Diet diversification
Food security
Questions for Discussion
What is projected for human population in the future?
How will we feed all of these people?
Human Population Growth
Thomas Malthus’, An Essay on the Principle of Population:
Geometric expansion of people
1x – 2x – 4x – 8x – 16x etc…
Linear increase in food supply
1 – 2 - 3 – 4 – 5 – 6 – 7…
Human Population
Feeding the hungry masses
North Korea (2 million deaths)
Many areas of Africa
Afghanistan
One person in seven is chronically underfed
Human Population Growth - Factors
Dependable food production, transportation
Rising incomes Improved housing and hygiene Medical advances
Life expectancy in 1900: 47 years in 1998: 75 years

Human Population Growth
In the last half of the previous century:

Human Population Growth
Page 5, Fig 1.6, Chrispeels and Sadava. Plant, Genes and Crop Biotechnology. 2nd Ed.
Human Population Growth
Fertility will continue to decline to replacement in 2050
Life expectancy will continue to improve (HIV?)
Overall population will level off at 10.5 billion people by 2150.
UN Population Division predicts:
Greatest growth – greatest need – in areas of the world where subsistence farming is practiced
Human Population Growth
Migration:The U.S. receives over 1 million immigrants a year
Europe migrants from North Africa and Middle East
From southern and eastern Europe to the western European nations
Human Population Growth
Migration: within countries common
In developing nations in 1850, 11% of the population lived in the cities
Currently, 84% of the population lives in urban areas
Human Population Growth
How do we increase food supply to match increasing populations?
Increase amount of land in production.
Increase the productivity of land already in use.
Sustainability issues (Earth Summit II)
Human Population Growth
Importance to a class in Vegetable Crops?
Caloric needs versus Nutritional needs
There is a shortage of food materials (fruits and veggies, tubers, root crops, nuts),which are the most important plant foods to supply humans with many of their nutritional needs:
minerals, vitamins, proteins, starches, fats, and sugars.
Human Population Growth
“If the global community continues to work together to find ways to increase agricultural productivity and income sustainability, it will be able to meet the challenges of a growing world population while providing better, healthier life for all the world's citizens. Better agriculture unleashes economic growth, raises incomes and leads to smaller families.”
