In the world of increasing population the demand for increase in growth of the food increases, this demands greater productivity with greater quality. The aim of AUTO FARMER USING RENEWABLE ENERGY is to provide automation and create a imprint in the field of agriculture. Today the farming underwent many difficulties like depending on rain, the restless manual work and the efforts .

Automation is the use of control systems such as computers, microcontrollers. II. LITERATURE SURVEY In the world of man and machines there is a revolutionary change of machines dominating the world of man. AUTO FARMER is one of the mean machine project. Improving irrigation efficiency can contribute greatly to reducing production costs of vegetables, making the industry more competitive and sustainable. Through proper irrigation, average vegetable yields can be maintained (or increased) while minimizing environmental impacts caused by excess applied water and subsequent agrichemical leaching. Recent technological advances have mades oil water sensors available for efficient and automatic operation of irrigation systems. Automatics oil water sensor-based irrigation seeks to maintain a desired soil water range in the root zone that is optimal for plant growth. The target soil water status is usually set in terms of soil tension or matric potential (expressed in kPa or cbar, 1 kPa=1 cbar), or volumetric moisture (expressed in percent of watervolume in a volume of undisturbed soil). Another benefit of automatic irrigation techniques is convenience. In a previous experience working witha soil-moisture-based automatic irrigation system, Dukes et al. (2003) found that once such a system isset up and verified, only weekly observation was required. This type of system adapts the amount of water applied according to plant needs and actual weather conditions throughout the season. This translates not only into convenience for the manager but into substantial water savings compared to irrigation management based on average historical weather conditions.
