Abstract

Agriculture is considered the backbone of Tanzania's economy, with more than 60% of the residents depending on it for survival. Maize is the country's dominant and primary food crop, accounting for 45% of all farmland production. However, its productivity is challenged by the limitation to detect maize diseases early enough. Maize streak virus (MSV) and maize lethal necrosis virus (MLN) are common diseases often detected too late by farmers. This has led to the need to develop a method for the early detection of these diseases so that they can be treated on time. This study investigated the potential of developing deep-learning models for the early detection of maize diseases in Tanzania. The regions where data was collected are Arusha, Kilimanjaro, and Manyara. Data was collected through observation by a plant. The study proposed convolutional neural network (CNN) and vision transformer (ViT) models. Four classes of imagery data were used to train both models: MLN, Healthy, MSV, and WRONG. The results revealed that the ViT model surpassed the CNN model, with 93.1 and 90.96% accuracies, respectively. Further studies should focus on mobile app development and deployment of the model with greater precision for early detection of the diseases mentioned above in real life.

用于早期检测坦桑尼亚玉米条纹病毒和玉米致死坏死病的深度学习模型。
农业被认为是坦桑尼亚的经济支柱,60% 以上的居民依靠农业生存。玉米是该国最主要的粮食作物,占农田总产量的 45%。然而,由于无法及早发现玉米病害,玉米的产量受到了挑战。玉米条斑病毒(MSV)和玉米致死坏死病毒(MLN)是常见的病害,农民往往发现得太晚。因此,需要开发一种早期检测这些疾病的方法,以便及时治疗。本研究调查了开发深度学习模型用于早期检测坦桑尼亚玉米疾病的潜力。收集数据的地区包括阿鲁沙、乞力马扎罗和马尼亚拉。数据是通过植物观察收集的。研究提出了卷积神经网络(CNN)和视觉转换器(ViT)模型。四类图像数据被用于训练这两种模型:MLN、Healthy、MSV 和 WRONG。结果显示,ViT 模型超过了 CNN 模型,准确率分别为 93.1% 和 90.96%。进一步的研究应侧重于移动应用程序的开发和模型的部署,以便在现实生活中更精确地早期检测上述疾病。
