Additionally, mechanical weeding can lead to crop injuries and decreases soil quality. Site-specific weed management can reduce the drawbacks of weeding regulation. Precision application of herbicides is well known and practiced, however for mechanical weeding this is not the case. Site-specific mechanical weeding was tested in a maize (<em>Zea mays</em> L.) trial in the northwest of Germany in 2021 and 2022. In this research, multispectral images from unmanned aerial vehicles (UAV) were used to detect weeds with an overall accuracy between 85 and 92 %. These images were used to generate application maps. Two weed control thresholds, based on the weed cover (WC) and relative weed cover (RWC) with three threshold levels each were compared with uniform weeding. In 2021, higher maize yields (1879 g m⁻² to 533 g m⁻²) and lower weed biomass (1151 g m⁻² to 731 g m⁻²) were observed due to higher precipitation than in 2022.

However, significantly less area was hoed in the site-specific treatments (−58 %), especially the treatments based on the RWC (−83 %).

Site-Specific Weed Management effectively addresses this issue but relies heavily on real-time and accurate weed detection algorithms.

The heart of TASA's innovation was to alleviate information conflicts among multiple distillation techniques and between distillation techniques and student models and to stop distillation at the appropriate time. We used channel pruning technology to compress the model volume and introduced Knowledge Distillation (KD) during fine-tuning to recover the model performance maximally. Concurrently, TASA was used to coordinate multiple distillation techniques to assist in recovering the model training. The experimental results indicated that the volume of the Optimized YOLOv5s was reduced by 79.2% compared to the YOLOv5s, while the mean Average Precision (<em>mAP</em>) and F1-score (<em>F</em>₁) reached 97.4% and 95.1%, respectively, with only decreased by 1.2% and 1.5%.

Enhancing crop production is imperative, given the substantial portion of land dedicated to agriculture. However, the multifaceted nature of farming, influenced by variables like soil composition, climate, and diseases, poses significant challenges. Embracing technological advancements is pivotal to augmenting crop yields and ensuring sustainable agricultural practices. This study introduces an innovative hybrid architecture that addresses significant challenges in agriculture by identifying leaf diseases and detecting crops using deep learning and sophisticated image-processing techniques. Here, the proposed model comprises two phases namely, Crop Prediction and Leaf Disease Identification. To improve its suitability for analysis, the input image is first preprocessed. An improved U-Net segmentation algorithm has been employed to identify areas of interest in the image. Features pertinent to shape, color, and texture, including an enhanced Local Gabor XOR pattern (LGXP), are then extracted to capture comprehensive information about the crops and potential diseases. The core of our approach lies in a hybrid architecture, integrating elements of Improved Linknet and LeNet architectures. This model first determines the kind of crop in the image by using features that have been extracted. In the following step, deep features and statistical characteristics extracted from the segmented image are used to identify numerous prevalent diseases affecting the foliage. Implemented in Python, our approach is rigorously evaluated against conventional models, showcasing superior performance across various metrics. Consequently, the model has achieved a higher detection accuracy of 0.982 and the F-measure of about 0.956, indicating that the model operates better and identifies the leaf disease more successfully than other existing techniques.
