“…Picual yield, leaf mineral content and fruit properties which comes in contrast with obtained data from cv. Manzanillo olive trees in Mexico where urea application did not be proven as valuable to alleviate of low fruit set in high temperatures (Abd El Migeed et al 2017;Navarro-Ainza et al 2016).…”

Konservolia and Kalamon olive orchards were tested for their vegetative and fruit growth after foliar urea applications served as nitrogen nutritional delivery scheme. Five urea aerial fertilizations (8-65 kg/m 3 /ha) from January to September with summer aerial supplement of buffered KNO3 replaced regular fertilization program for the above-mentioned olive orchards. Despite of different stem growth rates due to seasonal effect on tree physiology, throughout the experimental period no major changes in biomass productivity were observed for both varieties. Final size Konservolia fruits did not differ among conventional and foliar urea treatments. Although Kalamon olive fruits including pit data, differ in size among fertilization strategies with bigger size observed in foliar urea treated areas; their flesh firmness was found to be significantly lower to fruits received from soil fertilized orchards. Both varieties produced olives with increased pit weight and size and lower fruit flesh firmness when trees treated with urea. Konservolia decreases its fruit flesh/pit ratio as opposed to Kalamon where treated trees increased the weight of their commercial fruit flesh. Data suggest that each of tested olive varieties respond differently in foliar application of urea as a replacement of soil fertilization strategies. Results for Konservolia reveal that urea foliar applications can be approached as safe, conservative tactic nutritional replacement to soil fertilization for the orchard trees. For Kalamon variety, aerial treatments positively affect fruit size, increased pit size and flesh/pit ratio providing potentially faster harvest maturity times. This alternative nitrogen fertilization delivery strategy for Kalamon olive orchards can be considered as viable approach to restrict groundwater nitrate leaching and atmospheric pollution from previous fertilization conventional plans and increase fruit biomass for olive oil and olive waste byproducts useful in circular economy.

“…Conversely, Navarro-Ainza and López-Carvajal (2013) confirmed that a temperature above 30°C restricts fruit-setting, and Navarro-Ainza et al (2016) determined that the ideal temperature is 25°C; in this sense, the temperature in the Alto Ricaurte is on average 27.6°C, consequently, it stimulates fruitsetting, but the olive varieties in this region are not accurately known.…”

The olive tree has expanded to several countries because of its easy adaptation to difficult edapho-climatic zones and high culinary and medicinal interest given the physicochemical composition of its fruit, including Argentina, Chile, Peru and Mexico, which have similar soil and climate conditions to the Mediterranean, where the phenological stages correspond to clearly distinct climatic seasons. However, in the Alto Ricaurte region in Boyaca, Colombia, olives do not set because of the tropical climate conditions. Because of these characteristics, the behavior of some trees, sown 4 to 30 years ago in this region, were evaluated. The temperature and precipitation were measured, and 20 branches were selected per tree, which were monitored from appearance until development; the polar and equatorial diameter of the fruits were measured until reaching maturation. A fruit and oil analysis was carried out with olives harvested in two maturation states in 2017. The temperature had a positive correlation with the phenological stages in a range of 11 to 29°C, which directly influenced the development of inflorescences and their performance. In the same year, there were two or more blooms with different intervals, where the same branch had inflorescences, flowers, freshly filled fruits and other mature fruits. As for the characteristics of the fruit and the oil, it was evident that the content of fatty acids was within the parameters required by the International Olive Council.
