Vegetable production technology and postharvest quality.

Development of approaches for assuring the quality of vegetable depends o­n a better understanding of the influence of preharvest factors.Quality of vegetable crops during storage are influenced by the environmental conditions and the production technology.Some pre-harvest factors are closely bound and others act in independent from.To provided high quality and value added to the product, a high quality material and optimization in the different postharvest stages is required.Economic realities will also exert a strong influence o­n the type of crops grown and the methods used to produce the crops.Sustainable agriculture aims at preserving the environment, productive resources and meeting social requirements.

People demands a sustainable agriculture using low input productions and less toxic agrochemicals.In this way, we may foresee risks and take preventive measures during the crop production and the commercial chain towards the consumers.Organic and low input production systems maintain the soil and crop productivity for avoiding the environmental pollution.Also, soilless system allows the control of plant growth and development with an efficient utilization of resources and almost no environment deterioration.Thus, the adjustment of water consumption crop, irrigation solutions and drainages allow less use of water and fertilizers.This production system is a suitable alternative technique of using soil fumigations in conventional vegetable production systems as open field as under greenhouse.

This aim of this study was to determine the influence of nitrogen fertilization and vegetable production systems o­n postharvest quality to develop technologies to enhance the storage life of whole and fresh-cut vegetables.Organic and low input production systems in lettuce and tomato cherry crops, and soiless systems such as nutrient film technique and floating system in lettuce crop were evaluated.Relationships between vegetable production systems and postharvest quality were found.
