Abstract

In the backdrop of India\'s agrarian-centric economy, the precision of crop yield prediction and the adoption of optimal farming practices emerge as critical components for sustainable agricultural development. This research paper introduces an innovative methodology that integrates data mining techniques, machine learning algorithms such as Support Vector Machines (SVM), and Regression algorithms, along with a comprehensive attribute analysis to establish a resilient crop yield prediction and recommendation system. The proposed system draws insights from a diverse range of attributes crucial for agriculture, including geographical location, soil pH for alkalinity assessment, nutrient percentages (Nitrogen, Phosphorous, and Potassium), real-time weather conditions sourced from third-party APIs, soil type, nutrient composition, and regional rainfall data. By amalgamating and scrutinizing these multifaceted attributes, our system aspires to furnish farmers with precise and dependable predictions regarding their crop yields.

III. DATASET INTRO

The Crop Yield Prediction Model aims to forecast crop yields based on a combination of historical crop yield data, soil characteristics, and climate conditions.

This model is a crucial component of the Integrated Agricultural Decision Support System, providing farmers with insights into potential harvests and aiding in effective crop management. To train the Crop Yield Prediction Model effectively, crucial input features are considered. These include historical crop yield data, specifying crop types and yield per hectare, soil characteristics such as soil type, pH levels, nutrient content (N, P, K), and organic matter, and climate data encompassing temperature, precipitation, humidity, wind speed, and solar radiation.

Exploratory Data Analysis (EDA) is a crucial step in the data analysis process. It involves the initial investigation and examination of data to understand its main characteristics, uncover patterns, identify trends, detect outliers, and test hypotheses. EDA is often performed before formal statistical modelling to gain insights into the data and inform subsequent analysis. The EDA has been performed on the data to make it ready for further process.

Label Encoding is a technique used in machine learning and data preprocessing to convert categorical data into numerical form. In Label Encoding, each unique category or label is assigned an integer value. This process is typically applied to categorical variables that have an ordinal relationship, meaning there is a meaningful order among the categories.

IV. METHODOLOGY

In this research paper, we present a comprehensive methodology for the implementation of a crop yield prediction model and fertilizer recommendation system. Our study focuses on leveraging machine learning techniques to predict crop yields accurately and recommend optimal fertilizer application strategies. The proposed methodology integrates various algorithms, including regression algorithms, support vector machines (SVM), and Gaussian process regression, to analyse and compare their performance in predicting crop yields and recommending the fertilizer for the soil.

The first step of our methodology involves collecting relevant data pertaining to crop characteristics, environmental factors, soil properties, and historical yield records. This dataset serves as the foundation for training and testing the prediction models. We then preprocess the data to handle missing values, normalize features, and address any outliers to ensure the robustness of the models.

Subsequently, we employ regression algorithms such as linear regression, polynomial regression, and decision tree regression to build baseline yield prediction models. These algorithms offer a traditional approach to modelling crop yield based on input features such as weather conditions, soil nutrients, and crop types.

A. Analysis

Using These algorithms ,we can predict the amount of yield that can obtained from the particular area based on some parameters. We can also recommend the crop for the land using various features and machine learning models. We can recommend required fertilizer for the land based on the crop and ither features. Some Machine Learning algorithms are performed well in some models. The Working Of the Algorithm for certain Model has been varied based on the type of the data and size of data Support Vector Machines (SVM) often perform well in scenarios where the data is characterized by clear margins of separation between different classes. SVM excels in high-dimensional spaces and is effective when the number of dimensions is greater than the number of samples. It is particularly powerful in situations where the data exhibits non-linear relationships and can be effectively employed for both classification and regression tasks. SVM's robustness and versatility make it suitable for various real-world applications with complex decision boundaries. Gradient Boosting algorithms, like XGBoost or Gradient Boosted Decision Trees, excel when modelling complex relationships in data. They perform well in situations with heterogeneous features and diverse patterns. The iterative boosting process, focusing on misclassified instances, enhances model accuracy over iterations. Gradient Boosting is effective for both regression and classification tasks, demonstrating high predictive performance and resilience against overfitting, making it a powerful choice for a broad range of machine learning applications.
