🌾 CropYQ — Crop Yield & Quality Prediction Models

Repository: BirendraSharma/cropyq

This repository hosts two trained machine learning models for predicting agricultural crop yield and quality across India, Nepal, and the Netherlands, based on FAO crop production data.

---

📦 Models Included

File	Type	Description
regression_model.pkl	Scikit-learn Regressor	Predicts crop yield in kg/ha (log-transformed target, inverse-transformed on output)
xgboostClassification_model.pkl	XGBoost Classifier	Predicts crop quality as Low / Medium / High

---

🗂️ Input Features

Both models share the same 5-feature input vector:

Feature	Type	Description
Area	Encoded int	Country (India=0, Nepal=1, Netherlands=2)
Item	Encoded int	Crop type (38 categories, e.g. Wheat=36, Rice=27)
Crop Group	Encoded int	Cereal=0, Fruit=1, Oilseed=2, Pulse=3, Root=4, Vegetable=5
Flag	Encoded int	FAO data flag — A=0, E=1
Year	int	Year offset from 1961 (e.g. 2020 → 59)

🚀 Quickstart

Install dependencies

pip install huggingface_hub scikit-learn xgboost numpy

Load and use the models

import pickle
import numpy as np
from huggingface_hub import hf_hub_download

REPO_ID = "BirendraSharma/cropyq"

# Download and load regression model
reg_path = hf_hub_download(repo_id=REPO_ID, filename="regression_model.pkl")
with open(reg_path, "rb") as f:
    reg_model = pickle.load(f)

# Download and load classification model
clf_path = hf_hub_download(repo_id=REPO_ID, filename="xgboostClassification_model.pkl")
with open(clf_path, "rb") as f:
    clf_model = pickle.load(f)

# Example: Wheat in India, Cereal group, Flag A, Year 2020
# area=0 (India), item=36 (Wheat), cropgroup=0 (Cereal), flag=0 (A), year=2020-1961=59
inputs = np.array([[0, 36, 0, 0, 59]], dtype=np.float32)

# Predict yield (kg/ha) — model was trained on log1p target
log_yield = reg_model.predict(inputs)[0]
yield_kgha = np.expm1(log_yield)
print(f"Predicted Yield: {yield_kgha:.2f} kg/ha")

# Predict quality
quality_map = {0: "Low", 1: "Medium", 2: "High"}
quality_pred = clf_model.predict(inputs)[0]
print(f"Predicted Quality: {quality_map[int(quality_pred)]}")

🖥️ Desktop GUI App

A Tkinter-based desktop app is available that provides a point-and-click interface for running predictions.

Run the app

pip install huggingface_hub scikit-learn xgboost numpy tkinter
python crop_yield_app.py

The app will automatically download both model files from this repository on first launch.

Features:

• Dropdown selectors for Area, Item, Crop Group, and Flag
• Text entry for Year
• Predict Yield button → returns estimated kg/ha
• Predict Quality button → returns Low / Medium / High

🔢 Encoding Reference

Area Encoding

Area	Code
India	0
Nepal	1
Netherlands (Kingdom of the)	2

Crop Group Encoding

Crop Group	Code
Cereal	0
Fruit	1
Oilseed	2
Pulse	3
Root	4
Vegetable	5

Flag Encoding

Flag	Code	Meaning
A	0	Official figure
E	1	Estimated value

Year Encoding

Year values are offset from 1961:

encoded_year = actual_year - 1961
# e.g. 2020 → 59,  1990 → 29,  1961 → 0
