Intelligent Crop Recommendation System Using Machine Learning

The Intelligent Crop Recommendation System Using Machine Learning is a comprehensive machine learning solution that recommends crops based on soil nutrients and environmental parameters. This project is ideal for B.Tech, MCA, CSE, and engineering students as their final year project. It implements Random Forest and Decision Tree with 5-fold cross-validation, achieving 97.5% accuracy and 97.5% F1-score.

The system utilizes the Crop Recommendation dataset containing 2,200 samples with 7 key features: Nitrogen (N), Phosphorus (P), Potassium (K), temperature, humidity, pH, and rainfall, targeting 22 distinct crop types. It provides a user-friendly web interface for data upload, exploratory analysis, model training, and crop prediction, making precision agriculture accessible to farmers and agricultural experts.
