| Popis: | Most of the fig orchards are trained to an open vase system. Although this system is adapted to the wide canopy of the fig it was questioned whether it is the best system for intensive culture. With the interest in growing figs under nets for protection against insects, a training trial was initiated to identify the best system for high yield and high quality fruit. Net cover was found very efficient to protect against various insects attacking fig fruit especially the fig fly (Silba adipata) that causes severe damage in warm growing locations. A 17 mesh white polyethylene net that exhibits total protection but has but a small effect on changing the microclimate was used. The net was UVA treated and could stay in the orchard for ca 10 years. A comparative trial was set up in 1994 under net in Bet Dagan, Israel with the Nazareth breba cv. It included an open vase training planted 5*4 m and a V shaped system with the 2 arms perpendicular to the row axis planted 5*2 m at 4 replicates of rows 60 m long. Yield was monitored from the 4th year on. Yields during 3 years of data collection were significantly higher in the V shape system than in the open vase one. In the year 2000 it reached 23.5 T/ha in the V training vs. 13.5 T/ha in the open vase training system. No difference in fruit quality was noted. |
