Halo blight, one of the major diseases mungbean, is caused by bacterium Pseudomonas savastanoi pv. phaseolicola. The pathogen infects foliar parts plant, causing water-soaked spots that eventually develop surrounding yellow margins. disease particularly destructive under moderate temperature and high humidity, especially when it occurs during late vegetative through to early reproductive stage....

Crop pests and diseases are one of the most critical disasters that limit agricultural production. In this paper, we trained a lightweight convolutional neural network model built Django framework-based potato disease leaf recognition system, which can recognize three types images including early blight, late healthy. A lightweight, network-based for identification significantly reduces number ...

Late blight caused by Phytophthora infestans is a destructive disease in potato production, which can lead to crop failure severe cases. This study combined visible/near-infrared (Vis/NIR) spectroscopy with machine learning (ML) and chemometric methods for rapid detection of late blight. The determination severity was accomplished two directly or indirectly based on differences reflectance. One...

Abstract Genetic gains (Δ G ) are determined by the breeders' equation Δ = [( ck σ 2 )/( y P )], where c , k and parental control, a function of selection intensity number years to complete one cycle, respectively, while genetic variance square root phenotypic variance. Plant breeding programs should deliver above 1% annual after testing selection. The aim this research was estimate in potato c...
