Plant Nutrition Impacts on Vegetable Quality - The use of fertilizers is an important component of commercial vegetable production.

Effects of Water and Nutrients on the Postharvest Quality and Shelf Life of Citrus - "Irrigation and fertilization practices can also have significant impacts on fruit quality and shelf life during harvest, packinghouse operations, storage, and distribution. These include effects on fruit color, texture, disease susceptibility, juice composition, and the development of physiological disorders..."

Florida Citrus Pest Management Guide: Preharvest Control of Postharvest Decays - "An application of fungicide up to 3 weeks prior to harvest will protect fruit from these diseases during the degreening process or during delays following harvest."
