In this paper design for fuzzy logic based irrigation controller using penman-Monteith equation is proposed. The irrigation requirement for any crop is the amount of water that must be applied to meet the crop's evapotranspiration (ET). The amount of (ET) includes water that is needed for both evaporation and transpiration. Penman Monteith equation is used to compute the actual evapotranspiration. Here difference between actual and desired evapotranspiration is one of the input parameter to fuzzy inference system. The longer the crop growth period the higher is the water requirement. Therefore month after sowing a crop is also an important parameter taken into consideration. As there is no mathematical model exists for both parameters, fuzzy logic technique is most suitable for modeling. This paper also discusses fuzzy inference system for fuzzy irrigation controller.
