Remote estimation of leaf nitrogen content, leaf area, and berry yield in wild blueberries

Autor: Kenneth Eteme Anku, David C. Percival, Rajasekaran Lada, Brandon Heung, Mathew Vankoughnett

Publikováno v: Frontiers in Remote Sensing, Vol 5 (2024)

Nitrogen (N) fertilization is a major management requirement for wild blueberry fields. Its presence and estimation can be difficult given the perennial and heterogeneous nature of the plant, low N requirement, and residual N effects, resulting in th

An investigation into the potential of Gabor wavelet features for scene classification in wild blueberry fields

Autor: Gashaw Ayalew, Qamar Uz Zaman, Arnold W. Schumann, David C. Percival, Young Ki Chang

Publikováno v: Artificial Intelligence in Agriculture, Vol 5, Iss , Pp 72-81 (2021)

A Gabor wavelets based technique was investigated as a potential tool for scene classification (into one of bare patch, plant, or weed) for its ultimate utility in site-specific application of agrochemicals in wild blueberry fields.Images were gather

Soil Nutrient Availability, Plant Nutrient Uptake, and Wild Blueberry (Vaccinium angustifolium Ait.) Yield in Response to N-Viro Biosolids and Irrigation Applications

Autor: Aitazaz A. Farooque, Farhat Abbas, Qamar U. Zaman, Ali Madani, David C. Percival, Muhammad Arshad

Publikováno v: Applied and Environmental Soil Science, Vol 2012 (2012)

We compared the impact of surface broadcasted N-Viro biosolids and inorganic fertilizer (16.5% Ammonium sulphate, 34.5% Diammonium phosphate, 4.5% Potash, and 44.5% s and/or clay filler) applications on soil properties and nutrients, leaf nutrient co

Potential use of biofungicides and conventional fungicide for the management of Botrytis blossom blight in lowbush blueberries

Autor: Joel Abbey, Samuel K. Asiedu, Laura Jaakola, David C. Percival

Botrytis blight is an economically important disease of lowbush blueberry that causes significant yield loss annually. In this study, the biofungicides, Diplomat 5SC® (polyoxin D), Timorex Gold® (tea tree oil), Fracture® (BLAD) and Serenade MAX®

Elucidation of the molecular responses during the primary infection of wild blueberry phenotypes with Monilinia vaccinii-corymbosi under field conditions

Autor: Laura Jaakola, David C. Percival, Joel Abbey, Sherin Jose

Publikováno v: BMC Plant Biology
BMC Plant Biology, Vol 21, Iss 1, Pp 1-10 (2021)

Background Monilinia blight caused by Monilinia vaccinii-corymbosi (Reade) Honey (M.vc) is a major disease of wild blueberry that can result in severe crop losses in the absence of an integrated disease management programme. The fungus causes blight
