Overuse of synthetic fertilizer is one of the problems of farmers. Factors contributing to it
is the timing of fertilizer application. Farmers operate their farms in the traditional way
where most of them rely on the age or the days after transplanting the seed not based on
the crop’s needs. The purpose of this study is to develop a mobile application that will help
farmers easily determine the nitrogen content of rice and corn and recommend amount of
fertilizer to be applied based on Leaf Color Chart panel standards. The system was
developed using Android Studio for Android application development. Based on the results
of tests done such as functionality, reliability and portability. The application’s
functionality for rice analysis has obtained the highest mean of 80% and 70% for corn
analysis. The project’s reliability confirmed that the project can be installed and loaded
successfully despite the numerous number of users. While the project’s portability
confirmed that the application is accessible from Android Jelly Bean 4.3 OS up to Android
Lollipop 5.0 OS and that it works with phone’s having 2 megapixels camera. Based on the
results of the evaluation conducted using the ISO Software Product Quality, the project
was evaluated with a mean average of 4.11 which obtained “Very Good” rating. This
indicates that the system is beneficial to rice and corn farmers in terms of determining
nitrogen content of rice and corn.
