1 Vegetable History, Nomenclature, and Classification Introduction All societies and ethnic groups eat vegetables because they are essential for maintaining human health. In simple terms, modern vegetable science deals with growing herbaceous plants for human consumption to meet basic nutritional needs. As the world s population grows, the demand for vegetables will continue to grow as well. Vegetable science, sometimes called olericulture, is one of the most dynamic and important fields of the agricultural sciences. The importance of vegetables has never been greater. What is a Vegetable? Most definitions of a vegetable are not botanically based. Vegetable definitions are rather arbitrary by nature and commonly based on usage rather than plant morphology. For example, one widely used definition of a vegetable is: a herbaceous plant or portion of a plant that is eaten whole or in part, raw or cooked, generally with an entree or in a salad but not as a dessert. Of course there are exceptions to this definition. Rhubarb, watermelon and cantaloupes are all considered vegetables but commonly used as desserts. Mushrooms are fungi and not plants but are generally considered to be vegetables, and their production is described in a later chapter. Since vegetable is not a botanical term, some vegetables botanically speaking are also fruits. In a botanical sense, a fruit describes a ripened ovary containing seeds together with adjacent parts that are eaten at maturity. For example, tomato, pepper, bean and cantaloupe botanically speaking meet the definition of fruit, but because of the way they are traditionally used and produced they are considered to be vegetables. Therefore, since there are essentially two classification systems, some commodities may be classified as a vegetable based on their usage while at the same time they are botanically fruits. Vegetables are a horticultural food crop. Other horticultural food crops include small fruits and tree fruits, which are usually grown as perennials. Vegetable crops may be either annuals or perennials. From a production standpoint, a vegetable crop may be defined as a highvalue crop that is intensively managed and requires special care after harvest. Agriculturalists often segregate agronomic or field crops into a separate category as crops that are extensively grown and less intensively managed in comparison to vegetable and the other horticultural crops. Wheat, cotton, soybean, sugarcane and rice are all examples of agronomic crops. Many agronomic crops are grains that are planted and destructively mechanically harvested at full physiological maturity at the end of their life cycles. In contrast, many vegetable crops are harvested in an immature state, while still fragile, so great care must be taken to preserve their quality from the field to the consumer. There are some exceptions to these general production definitions. Some agronomic crops such as tobacco are intensively managed and are valuable in a monetary sense but are considered agronomic for historical reasons. Irish potato is considered to be a vegetable by some but an agronomic crop to others depending on the region, type and scale of production. Corn and soybeans can be either agronomic or vegetable crops depending on the cultivars grown, their stage of maturity at harvest and their end use. While these definitions are not perfect, they do have value in allowing us to group different crops and types of production to understand better the more unique aspects of vegetable production, management and handling compared to other crops. So in summary, vegetable is a term based on the usage of herbaceous plants or portions of plants that are eaten whole or in part, raw or cooked, generally with an entree or in a salad but not as a dessert, that are intensively managed and may require special care after harvest to maintain quality.

The Evolution of Vegetable Production Over the years, world vegetable production has increased. For example, there was over a fourfold increase in world vegetable production from 1970 until 2009 (FAO, 2011). The longterm increase has largely been the result of a series of technological advances. The first were laborsaving technologies such as the moldboard plow, and power equipment such as trucks, tractors and harvesting equipment. Subsurface drainage systems were developed to improve productivity of chronically waterlogged soils. During the first half of the 20th century, lowcost commercial fertilizers were mass produced, leading to dramatic improvements in fertility management and productivity. In the 1930s, new plantbreeding techniques led to development of more productive cultivars. One of the major genetic advancements during this period was the development of F1 hybrid cultivars, which increased the productivity of some vegetables by 30% or more. Many view the period after World War II as the chemical era of agriculture as many synthetic pesticides, e.g. fungicides, insecticides and herbicides, became readily available. Chemicals were intended to more easily control crop pests to enable a largescale, singlecrop production system called monoculture where only a single crop is grown in a field and all other vegetation is excluded. The monoculture system and the related technologies like chemical pest control and concentrated syntheticfertilizer usage were designed in part to reduce the amount of labor needed in agriculture so that one person could effectively manage more cropproduction acreage and increase productivity. During the 1970s and 1980s, concerns about human health issues led to interest in and the development of more sustainable and lowinput approaches to vegetable production. Also in the past 50 years, conservation tillage practices have been developed to reduce soil erosion, decreasing the number of passes made over a field to decrease soil compaction. Plastic mulches were developed to modify soil temperatures, control weeds, reduce leaching and use less water to produce vegetables. Trickleirrigation systems were developed to precisely apply water and nutrients to vegetable crops throughout the season. Raisedbed production systems improved drainage, encouraged better root development and reduced disease. During this same time frame, computer technology also impacted both production and management issues, increasing production efficiency. Despite these advances, there seems to be declining interest in vegetable science as a discipline in the academic circles of many developed countries. Government sponsorship of research on applied aspects of vegetable science in many developed countries has declined in recent years as funding has been diverted to more basic research in plant science. There is a perception that research on vegetablecrop production is no longer a high priority in countries with developed agriculture industries because most of the productionrelated questions have already been answered or are being addressed by the private sector. Some believe that production has become cookbook, so advanced training is no longer necessary. Most agriculturalists would agree that research has played an important role in advancing vegetable science to its current state. Innovative new research will be necessary in the future to meet the needs of a growing global population for safe, nutritious and sustainably produced vegetables. The need for primary information about vegetable production for the developing world remains great. Both now and in the future, research and education programs will be needed to address food safety and security issues. In many developed countries, only a very small percentage of people are involved in food production. This has led to misconceptions and uncertainty about where vegetables come from, the effect production has on the environment, and whether or not vegetables are safe to eat. Consumers need to be educated about their food supply to intelligently discuss timely topics such as the risks and benefits of transgenic crops. Accurate scientific information needs to be readily available about this and other key issues. Vegetable science is truly fundamental to our very existence because it is a discipline that deals with the basic needs of the human race rather than its wants. The following is a partial list of challenges that face commercial vegetable growers in many areas of the world; novel research approaches will be required to solve them. Understanding and controlling the causes of biological contamination on vegetable crops is a major challenge. Developing highly productive and efficient sustainable vegetable production systems is another. Improving the quality and nutritional value of commercial vegetables is an ongoing challenge.
