Each crop's growing conditions has a different vary.
The study aims to produce a decision support system in the determining of crop using Simple Additive Weighting (SAW) method by making requirements grow as a criterion. Terms grown used were the soil acidity, altitude, soil fertility, soil texture, humidity, rainfall, air temperature, and wind speed.
The system was developed using the PHP programming language and MySQL. The output of the system is a recommended best suitable crops to be planted by certain environmental conditions.
