This project is an continuation of an objective of existing CRDF funded project (# 00124558 ; ended in March 2019, final report submited to CRDF) with some added treatments to be evaluated in comparison to control (dry conventional fertilizer with foliar micronutrients). Objective 1 which is the continuation of # 00124558 included 10 treatments.Altogether currently there are 25 treatments of citrus nutrition that are being compared to control. Within this quater the we successfully acollected data on tree health, leaf and soil nutrition. We also applied fertilzer for spring at both sites. Due to low soil pH, we have skipped Tiger sul application and instead applied regular micronutirents. We are continuously monitopring soil pH and will resume Tiger Sul application when pH is high enough.In addition we recently harvested Arcadia site. The data on fruit yield, fruit size, huice quality has been collected. nfortunately, due to Covid-19 related restriction we could not perform sensory analysis, however we collected juice for flavor analysis in order to asses the effect of nutritional treatments on sensory aspect of juice. Currently, we are in process of data organization and analysis of field data and flavor analysis of juice samples.We are also getting ready to harvest second trial site. We anticipate to harvest it in next 2-3 weeks. This quarter the results of field trial were pesented at virtual OJ break.
