This study was undertaken to develop and evaluate thermal-RGB imagery and in-field weather sensing derived wetness prediction models as tools to help mitigate cracking. Increased fruit surface wetness triggers absorption of water in maturing fruits and leads to fruit cracking. Rain-induced cracking of sweet cherry (Prunus avium L.) fruit causes substantial economic loss to tree fruit growers annually. Overall, the developed CPS unit demonstrates a promising potential for reliable FST monitoring that could aid growers in real-time apple sunburn susceptibility prediction and actuation of sunburn preventive strategies. The weather model-predicted FST (FSTw) was found to be highly sensitive to fruit shading and a significant difference was recorded between FSTw and FSTi. Moreover, no significant difference was recorded between FSTi and FSTa. The results showed significant differences between FSTi, FSTi-max, FST10, FST15, and FST20 for Honeycrisp (F4,162 = 73.4, p < 0.0001) as well as Cosmic Crisp (F4,46 = 19.4, p < 0.0001) cultivars. Furthermore, imagery data was analyzed to derive mean FST (FSTi), maximum FST (FSTi-max), and mean FST of the 10%, 15% and 20% hottest part of the fruit surface (i.e. A contact type thermal probe of accuracy ☐.4 ☌ was also utilized for ground truth apple FST (FSTa) measurements. For each cultivar, field data was collected for three days between 12 and 5 pm at 5-minute intervals. Two automated CPS units were deployed in the commercial orchards of cv ‘Honeycrisp’ and ‘Cosmic Crisp™’ during the 2019 production season. Moreover, the processing unit was configured to acquire in-field weather data and to utilize a temperature dynamics weather model for weather-based FST estimation. The algorithm was optimized for processing the data on a single-board computer with limited computational resources. Acquired imagery data was analyzed in real-time using a custom-developed algorithm in python ‘OpenCV’ library to estimate imager-based FST. The CPS unit consists of a thermal-red-green-blue and all-in-one weather sensor integrated with a single-board computer. We developed a crop physiology sensing (CPS) unit that uses visible-infrared imagery and in-field weather data for FST monitoring, the prime indicator of sunburn susceptibility. Therefore, this study focuses on the development of a non-invasive and real-time sunburn monitoring tool. Existing approaches for sunburn prediction and management, based on atmospheric temperature data, are often unreliable and inefficient for timely actuation of remedial measures. Sunburn in apple may cause considerable crop loss and reduce fresh produce marketability. Such stressors increase the fruit surface temperature (FST) and prolonged exposure above a critical FST can result in sunburn. You can manually add these the "Command Contact Import Template".Heat and light-instigated abiotic stresses during summer can cause several physiological disorders in perennial specialty crops. Social Media profiles do not export from Top Producer. There are different source types in Top Producer: List Source, Closing Source, and Referral Source in Top Producer. Groups in Top Producer do not export, manually add the contact groups as User (Custom) Tags in Command. Use a User (Custom) Tag in Command if there is not a match. The Top Producer Contact Types do not match up with the System Tags in Command. Exiftool producers field and country field how to#The following table can help you determine how to match the Top Producer fields to the Command fields when you copy and paste to the "Command Contacts Import Template".Īlso a Secondary Birthday in Top Producer Leave any field blank on the "Command Contact Import Template" if you do not have data in that field.Click here to learn more about creating "Custom Fields". Manully add that information after your contacts have been imported. If Command does not have a field that is in Top Producer, you can create a "Custom Field" in Command. You can manually fill in any blank fields in the "Command Contact Import Template" for those fields to import to Command. If you use the "Command Contact Import Template", you will notice Top Producer does not have information for some Command fields.When you transfer your contacts from the Top Producer export file to the "Command Contact Import Template", you will need to know how the fields in these two different systems match up.
