“…Slash pine is grown in this area (Pinus Elliottii, (Coffin, pers. comm., 2022)) by private citizens in discrete field tree farms, and harvested for resin and timber (Dias et al, 2022). Since these fields were included with the agricultural data, these trees were treated as an agricultural crop for this project, rather than as a landcover class.…”

Synthetic Aperture Radar (SAR) is a useful tool for crop monitoring programs, which are critical components of agricultural supply chain management. Multifrequency SAR has the potential to close knowledge gaps that can occur using radar data with a single frequency.However, it may also add noise to a classification, depending on when and where the imagery was collected. This study applied Random Forest and Support Vector Machine classifiers to study areas in Saskatchewan, Canada and Georgia, USA to test whether multifrequency SAR could improve crop classification accuracies. Combined L-, C-, & X-band imagery provided the best overall accuracies when multiple crop types were being studied. Different crops had different responses to each frequency at different points in the growing season. Regions with complex cropping calendars pose extra challenges for choosing image acquisition timing. This research found that multifrequency SAR provided accuracies over 85% for both areas of interest.

Drought causes major agricultural losses, threatening food security worldwide. Thus, innovative strategies have been explored to improve crop tolerance to drought. This work focused on one natural peptide (PpT-2) with antioxidant activity, unexplored in plant applications, to evaluate its effectiveness in mitigating drought effect on Solanum lycopersicum L. plants. For that, tomato plants were foliar sprayed with different doses of PpT-2 (0, 15 or 150 mg L−1) and exposed to water Stressed and UnStressed conditions. The plant growth, photosynthesis and oxidative stress-related parameters were evaluated. Plant treatment with PpT-2, mostly at the highest concentration, alleviated diverse effects induced by water restriction: stimulated CO2 assimilation; improved ΦPSII, Fv/Fm and Fv’/Fm’; amended net CO2 assimilation rate and water use efficiency; restricted H2O2 accumulation and lipid peroxidation; stimulated SOD activity. Under UnStressed conditions, PpT-2 induced some degree of stomatal closure, nevertheless without restricting CO2 availability for the non-photochemical processes of photosynthesis, besides of decreasing H2O2 content and CAT activity. Overall, PpT-2 application controlled H2O2 accumulation, and under water limitations improved both photochemical and non-photochemical processes of photosynthesis and promoted drought tolerance, underscoring its potential for managing drought stress in crop species.
