Effects of several organic fertilizers on growth, development and quality properties of tomatoes obtained in organic system: a review

One of the main goals of today's agriculture is to produce healthy food and to increase the efficiency of plant production by protecting and conserving the environment. Organic tomatoes (Lycopersicon esculentum Mill.) represent one of the most valuable crops consumed widely either fresh or processed because for its sensory qualities, nutritional value and for its benefits on human health (reduce the risk of cardiovascular disease and certain types of cancer). Organic fertilizers are originated from plant and animal wastes and contain N, P, K and microelements. They are used to obtain the nutritional demands of plants for their growth and development, as well as improve the physical, biological and chemical properties in the soil. The objective of this study was to evaluate the effectiveness of organic fertilizers on quality characteristics (soluble solids contents, lycopene and carotenoids, titratable acidity, minerals and vitamins), on the growth and development of organically cultivated tomatoes based on the lasted valuable information.
