The aim of this review is to provide a brief review and identify the research gab regarding the influence of farm yard manure on yield attributes and bulb yield of onion. Excessive amounts of inorganic fertilizers are applied to vegetables crops in general and onion in particular in order to achieve a higher yield. However, continuous usage of inorganic fertilizer affects soil structure and generates several deleterious effects to the environment along with human health. Therefore, it is imperative to look for cheaper and environment friendly methods of soil fertilization. In this regard, the use of organic fertilizer which is beneficial and ecologically friendly has currently attracted considerable attention. Organic farming or organic foods are becoming symbol of healthy living and common people are getting more and more aware about what they are consuming. Of the organic fertilizers farm yard manure is majorly used in onion production. When we use farm yard manure for onion maximum care should be given for the amount to use, which depends on crop type, variety, soil fertility status and etc. Growth and yield of onion is affected by application of farm yard manure at different rates. Yield attributes of onion such as, bulb weight, bulb dry weight, bulb diameter and total bulb yield, and marketable yield are affected by farm yard application at different rates. To obtain higher values of these parameters the application rates of farm yard manure can be from 5 to 40t/ha depending on the above mentioned and other factors. In general it is also good if the application farm yard manure is integrated with recommended inorganic fertilizers, because now days, integrated nutrient management is becoming a viable strategy for promoting efficient use of chemical fertilizers with addition of organic manures.
