The prediction of crop yields internationally is a crucial objective in agricultural research. Thus, this study implements 6 regression models (Linear, Tree, Gradient Descent, Gradient Boosting, K- Nearest Neighbors, and Random Forest) to predict crop yields in 196 countries. Given 4 key training parameters, pesticides (tonnes), rainfall (mm), temperature (Celsius), and yield (hg/ha), it was found that our Random Forest Regression model achieved a determination coefficient (r^2) of 0.94, with a margin of error (ME) of .03. The models were trained and tested using the Food and Agricultural Organization of the United Nations data, along with the World Bank Climate Change Data Catalog. Furthermore, each parameter was analyzed to understand how varying factors could impact overall yield. We used unconventional models, contrary to generally used Deep Learning (DL) and Machine Learning (ML) models, combined with recently collected data to implement a unique approach in our research. Existing scholarship would benefit from understanding the most optimal model for agricultural research, specifically using the United Nations data.

利用6种回归模型（线性回归、决策树、梯度下降、梯度提升、K最近邻和随机森林）预测196个国家的农作物产量，并通过农药、降雨量、温度和产量4个参数，发现随机森林回归模型的决定系数（r^2）为0.94，误差（ME）为0.03。研究使用联合国粮食农业组织的数据和世界银行的气候变化数据训练和测试模型，并分析各个参数对农作物产量的影响。通过使用非传统的模型以及最近收集的数据，实现了独特的研究方法，旨在为农业研究找到最优模型，并利用联合国的数据进行研究。
