Vegetable production is a vital component of agriculture, and significant progress has been made in this area since independence, with an initial yield of just 5.8 tons per hectare. However, the increasing demand from growing populations necessitates further increases in vegetable productivity.

The constraints of shrinking land and water resources, coupled with the threat of climate change, require effective human and financial resources to support the development of technologies. The development of vegetable hybrids with genes for increased yield and resistance to biotic/abiotic stress, the production and protection of crops in problematic soils with reduced water and nutrient use, and safe pest and disease management, as well as the reduction of post-harvest losses and value-added processing are all important priorities.

The book "Vegetable Science: Objective Type" provides a comprehensive overview of vegetable crops, covering topics such as production, breeding, and biotechnology, as well as statistics, biometrics, and the application of computer technology. The book also includes a special chapter on General Agriculture, providing readers with up-to-date information on agricultural practices.
