CitrusYield: A Dashboard for Mapping Yield and Fruit Quality of Citrus in Precision Agriculture

Abstract

The application of new technologies in precision agriculture offers the possibility to link information to very specific crop locations. The spatial representation of these agricultural data through yield and fruit quality maps allows for crop management in a precise way that means that agricultural operations may be carried out considering intraorchard variability, thus resulting in greater efficiency. The aim of this work was to advance the development of new tools for the generation of yield and quality maps for precision agriculture. A new tool was implemented for citrus through a dashboard called CitrusYield that integrates the requirements demanded by technicians and farmers in terms of spatial distribution and the quality of their citrus production. The data for testing were collected by a prototype of a citrus harvest-assist platform. In order to obtain maps showing heterogeneity of production, an experimental plot with different varieties and variable production was chosen. The maps, tables and graphs showing different crop data were generated automatically by CitrusYield from the analysis of the data collected. The main advantage of knowing the differences in production between the swaths and areas inside the crop is to provide the grower with precise information to make accurate decisions for localised crop management, such as fertilisation, irrigation, pest and disease control, etc.

Comparison between flaming, mowing and tillage weed control in the vineyard: Effects on plant community, diversity and abundance

“…Plant cover was contained under tillage and flame weeding. Respect to mowing, the vegetation underwent a major disturbance which created a difficulty in re-sprouting [25]. Under mowing, instead, where many perennial and taller plants were detected, the plants were ready and adapted for a rapid regrowth (see also discussion about functional groups).…”

“…In particular, it was shown that type and intensity of management can produce marked changes in the biodiversity associated to the vineyard [20,24]. As an example, concerning the merely weed control, flaming was compared to glyphosate, hot foam and nonanoic acid for weed control, and it was shown that flaming and hot foam were more efficient than the other tested techniques [25]. In this work, the effect of one-sided biomass-fueled flaming at different intensities (slow and fast speed flaming) on plant community composition and abundance in the vineyard was assessed in comparison to mechanical tillage and mowing techniques.…”

Endophytes of Brazilian Medicinal Plants With Activity Against Phytopathogens

“…The production of citrus is an important agricultural activity, and in Brazil it occupies a relevant position in the production of fruit, both for the fresh fruit market and to produce concentrate orange juice ( Carvalho et al, 2019 ; González-González et al, 2020 ). However, this important crop is affected by different pathogens, such as Colletotrichum abscissum , Phyllosticta citricarpa, Xanthomonas citri subsp.…”

Viewpoint Analysis for Maturity Classification of Sweet Peppers

“…In precision agriculture, maturity classification is important in phenotyping [ 14 ], and mapping yield and quality for management decisions (e.g., irrigation, fertilization [ 15 ]). Maturity is an important factor in determining the storage life and ripening quality of fruits [ 16 ] and influences the market value and choice of the consumer [ 17 ].…”
