Special Issue Information

Dear Colleagues,

Scientists and growers are aware of the major challenges primary crop production needs to overcome in the next decades: to produce more biomass and food per unit area; to increase the quality of agricultural products; and to reduce costs. All this under consideration of a more rational use of production resources, without disregarding the natural environment. Optical sensors play a key role for improving crop performance in changing environments. In particular, the spectrally resolved reflectance and fluorescence signals enable a fast and precise non-destructive monitoring of biochemical and physiological processes; as often demonstrated in more basic sciences. On the other hand, the demand exists—and the time has come—to use this knowledge for improvement of crop performance in the modern and intensive realm of agriculture.

Under field conditions, crops are exposed to a range of potentially stressful factors, including water and nutrient availability, salinity, as well as atypical temperatures. Moreover, biotic factors drastically constrain achievable yield and quality. In this context, spectral signals and signatures might be recorded, processed and transformed into information to early detect and differentiate single and multiple stresses in order to support a more target-oriented crop management.

Further, interesting applications of spectrally resolved reflectance and fluorescence approaches are found under high-intensive and protected cultivation, such as horticulture. Here, production factors might be optimized to improve growth, yield and product quality—often outside of the ideal cultivation period—and thereby exploiting the genetic potential at maximum. Also, the potential of reflectance and fluorescence techniques as supporting tools for phenotyping and selection of promising genotypes in breeding lines is still underexplored.

This Special Issue of Agriculture covers the following list of major topics, but is not limited to:

  • Sensing and differentiation of stress factors, and their single or combined impact, on the performance of field and horticultural crops.
  • Spatio-temporal changes of the spectral signatures due to biotic and/or abiotic stresses as information basis for precision agriculture.
  • Development, improvement and/or validation of sensors (including those mounted on unmanned aerial vehicles, UAV), spectral indices, or tools for data and image analysis.
  • Detection, characterization and differentiation of plant species (e.g., weeds and major crops), genotypes or physiological stages.
  • Imaging and functioning of plant structures.
  • Estimation of photosynthetic activity, water content, as well as the content and/or composition of plant pigments in leaves and fruits.
  • Phenotyping, identification of functional traits, selection of genotypes in breeding lines.
  • Target-oriented management of production resources (e.g., water, fertilizers, light, agrochemicals) for improved crop performance.
  • Reviews addressing specific issues on the use of spectrally resolved reflectance and fluorescence techniques for improved agricultural production.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 300 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
