Potential of UAS-Based Remote Sensing for Estimating Tree Water Status and Yield in Sweet Cherry Trees

Víctor Blanco, Pedro José Blaya-Ros, Cristina Castillo, Fulgencio Soto-Vallés, Roque Torres-Sánchez, Rafael Domingo
2020 Remote Sensing  
The combination of the VIs studied was used in two machine learning models, decision tree and artificial neural networks, to estimate the extra labor needed for harvesting and the sweet cherry yield.  ...  Four airborne flights were carried out during two consecutive seasons; to compare the results of the remote sensing VI, the conventional and continuous water status indicators commonly used to manage sweet  ...  Concerning crop yield estimates, the positive results of both DT and ANN obtained by the combination of remote sensing indices highlight the usefulness of UAS imagery for yield prediction in sweet cherry  ...

2020 Antioxidants  
In this research, a model for the estimation of antioxidant content in cherry fruits from multispectral imagery acquired from drones was developed, based on machine learning methods.  ...  For two consecutive cultivation years, the trees were sampled on different dates and then analysed for their fruits' radical scavenging activity (DPPH) and Folin–Ciocalteu (FCR) reducing capacity.  ...  Thanks to the personnel of the Soil Laboratory of the Institute of Soil and Water Resources, seated in Thessaloniki, Greece, for the soil analyses.  ...

Technologies for Forecasting Tree Fruit Load and Harvest Timing—From Ground, Sky and Time

Nicholas Todd Anderson, Kerry Brian Walsh, Dvoralai Wulfsohn
2021 Agronomy  
Current practice estimates orchard fruit load based on the qualitative assessment of fruit number per tree and historical orchard yield, or manually counting a subsample of trees.  ...  This review considers technological aids assisting these estimates, in terms of: (i) improving sampling strategies by the number of units to be counted and their selection; (ii) machine vision for the  ...  D.W. is linked to Pronofrut, a provider of yield estimation services in Chile and Spain.  ...

Forest fertilization: Trends in knowledge and practice compared to agriculture

Philip J. Smethurst
2010 Plant and Soil  
In relation to the knowledge base for fertilizer management, forestry and agriculture have similar practical questions that drive research, i.e. nutritional diagnosis and the development of fertilizer  ...  Plantation forestry and agriculture lack a mechanistic basis for evaluating base cation availability that accounts for Al-pH-root interactions.  ...  A key concept in agriculture is that resource use efficiency is based on product yield per unit of resource supply (e.g. Passioura 2004 for water).  ...
