Abstract:
Lettuce (Lactuca sativa L.) is a cool season leafy vegetable grown throughout the world. Due to its high nutritious profile it is regarded as one of the most significant salad crop. Due to the high demand of lettuce in the market, producers are using huge amount of chemical fertilizers to satisfy that market needs. However, extensive use of synthetic fertilizers is creating negative impact on human health, soil health and environment health, which is forcing growers to seek for better options. In such a scenario scientists have come up with organic fertilizers as promising and better alternative to inorganic fertilizers. Natural fertilizers are derived naturally from different substances such as animal waste, plant waste or human excreta. Some of the noted perks of using organic fertilizer in lettuce are increased plant height, number of leaves, fresh plant weight, Plant dry weight, fresh and dry weight of root, yield and nutritional value. As application of organic fertilizers can significantly improve the growth, yield and quality of lettuce without negatively impacting the environment and human health therefore, the current knowledge describing the effect and relevance of organic fertilizers in lettuce production is reviewed here.
