Abstract: Solanaceous vegetables play a significant role in human nutrition by providing minerals, vitamins and phytochemicals. They also make the food attractive by their colour, texture and flavor. An ability of plant leaves to absorb water and nutrients was recognized approximately three centuries ago. Studies related to the principles and mechanisms of foliar application continued during 20^th century. Foliar fertilization is a technique of feeding plants by applying water soluble fertilizer directly to the leaves. It is used as a means of supplying supplemental doses of macro and micronutrients. Foliar fertilization is considered when soil nutrient availability or root activity is restricted. Foliar nutrition can prove a great tool in correcting the nutrient deficiencies and providing much needed nutrients during stages of high nutrient demand in crop. The factors affecting the absorption of nutrients are spray solution, environmental conditions, leaf characteristics and plant state. Foliar nutrition can be helpful to provide nutrients directly to the site of metabolism which improves plant health, rapid result and reduced growth.
