Optimal Cultivation Strategies and Prediction of Fresh Weight in Vegetable Farming

Crops grown in open fields are greatly affected by various environmental factors such as climate, temperature changes and precipitation which can significantly influence crop yields depending on cultivation methods and environmental conditions. Therefore, this study proposes cultivation strategies to maximize the yield of onions and garlic along with methods for predicting bulb weight. An experimental site was established at the Allium Crop Research Institute in Muan, where growth characteristics were manually measured, and vegetation indices were acquired using multispectral imaging, along with corresponding bulb weights for both onions and garlic at regular intervals. To predict bulb weight, three predictive models were applied: NFCRM, RFRM, and 1D-CNN+Attention BiLSTM. Comparative analysis of predictive performance showed that NFCRM outperformed the other models, RFRM and 1DCABL, in predicting of the bulb weight of both onions and garlic.
