Objectives: In order to find out the differences in source–sink characteristics of ratooning rice and main season approaches increase grain yield rice, a sowing-by-stage method was adopted synchronize with induce their key growth stages under similar environmental conditions. The four varieties ecological conditions were examined 2019 2020. Results: results were: (1) leaf area index (LAI) range...

Abstract The effect of four concentrations (0, 3, 1, 5%) the nanopesticide neem leaf extract was tested on stages hairy grain beetle at five time times (1, 2, 5, 7) days. results showed that there is Significant differences between three 5) compared to fourth concentration, which represents control treatment, where it noted hatching rate egg stage lowest 5% concentration. As for larva and pupal...

cucumbers grown under open air conditions, encounters chilling damages, during cold seasons. plastic tunnels provide suitable heat environment for growing cucumber. the objective of this research was to evaluate cucumber phonological stages and leaf area expansion within three different plastic tunnel microclimates to moderate air temperature and air humidity. three microclimates including 1. c...

The segmentation of individual leaves in plant images is still a challenging task, especially in case of leaf overlaps. The exact determination of individual leaf areas could improve the biomass estimation which is a good indicator for plant performance. In addition, the number of leaves is directly related to plant development, leaf counts give insight into changing plant development stages. M...

Establishing an accurate, fast, and operable method for diagnosing crop nutrition is very important for crop nutrient management. In this study, static scanning technology was used to collect images of a rice sample's fully expanded top three leaves and corresponding sheathes. From these images, 32 spectral and shape characteristic parameters were extracted using an RGB mean value function and ...

Ginsenosides, the major compounds present in ginseng, are known to have numerous physiological and pharmacological effects. The physiological processes, enzymes and genes involved in ginsenoside synthesis in P. ginseng have been well characterized. However, relatively little information is known about the dynamic metabolic changes that occur during ginsenoside accumulation in ginseng. To explor...
