1. Investigating Spatial Relationship of Apparent Electrical Conductivity with Turfgrass and Soil Characteristics in Sand-capped Golf Course FairwaysTurfgrass quality decreases when grown on fine textured soils that are irrigated with poor quality water. As a result, sand-capping (i.e., a sand layer above existing native soil) is now considered during golf course fairway renovation and construction. Mapping spatial variability of soil apparent electrical conductivity (ECa) has recently been suggested to have applications for precision turfgrass management (PTM) in native soil fairways, but sand-capped fairways have received less...

2. Towards in Situ Monitoring of Root Growth Traits: Combining Spectral Imaging with Transparent Bed HydroponicsWe developed a novel method that enables non-laboratory monitoring of the growth characteristics of crop root systems by combining spectral imaging with a transparent bed hydroponics. Root systems of spinach grown were observed through the transparent bottom plate using a hyperspectral camera daily. An optimal index for the classification of root ages (days after emergence) was determined as the ratio of reflectance at 498 and 601 nm. Additionally, the distribution of root age was visualized over... D. Yasutake |
3. Assessment of Light Interception Considering Plant Architecture is Important for Yield Prediction in StrawberryCrop yield depends on whole‒plant photosynthesis, which is limited by the light interception by each leaf and its individual photosynthetic capacity. To date, there are some researches on assessments of yield considering their plant architecture and photosynthetic capacities in tomato and cucumber. However, there are few in strawberry although its cultivars exhibit considerable variation in their plant architecture and photosynthetic capacity. This research gap could significantly hinder accurate... D. Yasutake |
