5 DISCUSSION
As discussed Soybean is one of the most widely
cultivated crops globally, serving as a vital source of
protein and oil. However, the productivity and
quality of soybeans are significantly affected by
various diseases, such as rust, mosaic virus, charcoal
rot, brown spot. Accurate and early detection of
these diseases is critical to minimizing crop losses
and ensuring crop yield. Based on the review of
soybean crop diseases it is observed that CNN
models consistently perform better than Mask R-
CNN for SMV detection (Guia, Feia, et al. , 2021),
(Cui, Chen, et al. , 2011). The highest accuracy
96.25% is achieved by CNN with a dataset of 1199
images for SMV detection. A CNN-based model
achieves 95.76% accuracy for charcoal rot disease
(Khalili, Kouchaki, et al. , 2020),
(Nagasubramanian, Jones, et al. , 2018) while
sensitivity and specificity metrics for another dataset
(2000 samples) are reported as 96.25% and 97.33%,
indicating high reliability. CNN models are
primarily used, achieving up to 94.87% accuracy for
brown spot detection (Miao, Zhou, et al. , 2023),
(Bhujbal, Mandale, et al. , 2023), (Kashyap,
Shrivastava, et al. , 2022) .Random Forest (RF)
achieves95% accuracy, while SVM utilizes
hyperspectral images for Rust detection (Santana,
Otone, et al. 2024), (Ferraz, Santiago, et al. , 2024).
6 CONCLUSION
In Machine learning is becoming essential for
detecting crop diseases, significantly improving
agricultural productivity. By analysing large
datasets, these models can accurately diagnose
diseases like rust and leaf spot, with accuracy rates
up to 98%. However, the effectiveness of these
models can vary due to factors like data quality and
regional differences in disease symptoms. As
machine learning technologies advance, they could
be utilized to develop models that analyse soybean
images and other relevant data to detect SMV
symptoms more accurately and efficiently. While
promising, continued research is needed to enhance
the accuracy for different methodologies of machine
learning models across different crops and
conditions, ultimately supporting more sustainable
farming practices.
7 FUTURE SCOPE
The future scope includes exploring advanced
models like Vision Transformers and hybrid
approaches to improve accuracy across various
soybean diseases. Enhancing datasets with diverse
inputs, such as multispectral and hyperspectral
images, can improve the ability of models to
generalize and accurately identify diseases. These
advanced imaging methods offer detailed spectral
data, allowing models to better differentiate between
healthy and affected plants.
