A single breba fig cultivar, "Nazareth" (selected near Nazareth Israel), was found to produce regularly high value figs in all parts of the country. Examination of this cultivar in different locations revealed the potential of spreading its maturation from mid April in the Jordan Valley (300 m below sea level) to late June in the Galilee mountains. This is achieved by exploiting different climates and by using different timing of application of Dormex, a dormancy breaking agent. This chemical was found essential for inducing a synchronized development of the fig syconia while time of spray determined to a large extent time of bud break. To prevent drop of fruit especially in the early stages after anthesis, spray with gibberellic acid at 20 ppm was found to be beneficial. The fruit is attacked by various insects, especially the fig fly and the Mediterranean fruit fly as well as Drosophila flies at time of maturation. Experiments with a net cover led to a choice of a specific net that did not interfere with normal plant developments completely eliminated all insect damage to the fruit, giving complete protection without insecticide. By using a high density of orchard plantation, a high yield of 15 to 20 tones/hectare was obtained in an observation period of 5 years.
