“…Tannins, phytic acid and glucosinolates are the main anti-nutrients in DLF ( Amaglo et al, 2010 ; Ogbe and Affiku, 2011 ; Chodur et al, 2018 ). Tannins can precipitate proteins, amino acids, alkaloids and other organic molecules in aqueous solution, which hinder the absorption of some nutrients due to complexation.…”

The drumstick tree is a fast-growing multipurpose tree with a large biomass and high nutritional value. However, it has rarely been exploited as a protein source. This study investigated solid-state fermentation induced by Aspergillus niger, Candida utilis and Bacillus subtilis to obtain high-quality protein feed from drumstick leaf flour. The results showed that fermentation induced significant changes in the nutritional composition of drumstick leaf flour. The concentrations of crude protein, small peptides and amino acids increased significantly after fermentation. The protein profile was also affected by the fermentation process. Macromolecular proteins in drumstick leaf flour were degraded, whereas other high molecular weight proteins were increased. However, the concentrations of crude fat, fiber, total sugar and reducing sugar were decreased, as were the anti-nutritional factors tannins, phytic acid and glucosinolates. After 24 h fermentation, the concentrations of total phenolics and flavonoids were increased. The antioxidant capacity was also significantly enhanced.

“…Research shows that effective weed control at this stage is, in fact, essential to increased yield in some crops [2]. In recent times, effective weed control relies on the use of chemical weed controlsuch as herbicides with different sites of actionas they can kill from 90 to 99% of targeted weeds [3], [4]. Often, the drawback and most criticized aspect of chemical weed control as a current cropping practice is their apparent harmfulness to the environment.…”

To prevent yield losses, it is critical to eliminate competition between food crops and weeds at the onset of plant growth. While uniform spraying of herbicides can be economically and environmentally inefficient, site-specific weed management (SSWM) counteracts this by reducing the amount of chemical application with localized spraying of weed species. Past research on weed detection in SSWM has used a large deep convolutional neural network (DCNN) for weed detection. These models are, however, computationally expensive and prone to overfitting on smaller datasets. In this paper, we propose an approach to detecting weeds amongst plant seedlings using transfer learning in a small network. Our approach combines the mobilesized EfficientNet with transfer learning to achieve up to 95.44% classification accuracy on plant seedlings. Due to the robustness of transfer learning methods, this approach would be beneficial in improving both the classification accuracy and generalizability of current weed detection methods.

“…Topramezone is a 4-Hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor and prevents the biosynthesis of carotenoid that protects chlorophyll molecules from dangerous UV rays and excess light (Grossmann and Ehrhardt, 2007). There is nothing to prevent sunlight from penetrating into the leaves, which results in the photo-oxidation of chlorophyll molecules (Wang et al 2018).…”
