Quantifying genotypic and environmental factors affecting potato canopy growth
… to the tubers as yield. Variation in potato canopy growth can be analysed using non-destructive measurements and the size of the canopy determines radiation interception. Proportion of soil covered by green leaves (percentage of ground covered, GC) is a simple proxy for light intercepted. Two …

Effects of topping, stem density, and stage of vine cutting on canopy growth and tuber yield yield of potato (Solanum tuberosum L.)
… reimpose apical dominance on the rest of the canopy leading to production of few secondary branches. Therefore, several experiments were conducted at the Virginia Polytechnic Institute and State University Kentland Research Farm, Blacksburg in 1992, 1993, and 1994 to evaluate the effects of …

Factors affecting the levels of 3-isobutyl-2-methoxypyrazine and C6 compounds in Vitis vinifera L. Merlot.
… during the spring, i.e. a period of active vine growth, was found to be the main driver of fruit green aromas at harvest, likely due to interactions with vine vigour and fruit shading. A first field trial was conducted in 2009 and 2010 to investigate the influence of irrigation and N …

Effects of Transplant Season and Container Size on Landscape Establishment of Kalmia latifolia L.
… smaller plants, but better visual ratings. Root growth into surrounding soil was negligible for all treatments. Leaf area was higher for spring transplants than fall transplants. Experiment three was a rhizotron study with 19-L plants, transplanted in October or May. Canopy growth of spring …

Determination and Manipulation of Leaf Area Index to Facilitate Site-Specific Management of Double-Crop Soybean in the Mid-Atlantic, U.S.A.
… grain harvest does not always allow sufficient canopy growth to maximize photosynthesis and seed yield. This is due to a shorter growing season and moisture deficits common to the Mid-Atlantic USA. Leaf area index (LAI) is the ratio of unit leaf area of a crop to unit ground area and is a …

Informing on Crop Water-Use, Stress, and Growth with Integrated Satellite Remote Sensing and Modeling
… gaps and retrieve crop conditions, <em>e.g.</em> growth and health, that can enhance farm management practices.</p> <p>This dissertation examines the ability to monitor and identify crop conditions both spatially and temporally using the synthetic aperture radar (SAR) imagery, a sensor that …
