Abstract

The phenological, carpometric and yield characteristics of olive cultivars: Frontoio, Manzanilla, Ottobratica, Pendolino
and Picual were evaluated at different harvesting stages (Lemon green, Semi-ripe and Ripe) during 2014 and 2015 under
irrigation condition at Olive Model Farm Sangbhatti, situated in Mardan-Pakistan (Latitude: 34°16ʹ21.32ʺN; Longitude:
72°18ʹ06.33ʺ and Altitude: 375 m). Pendolino started early flower opening on 12th April, taken as baseline for
phonological attributes and took more days (9.50) to fruit set, while less days (6.33), started from 18th April were noted for
Ottobratica. The cultivars Manzanilla and Picual attained lemon green maturity after 193.50 (25th October) and 192 (22nd
October) days respectively, while 202.17 (2nd November) and 201.33 (1st November) days were taken by these cultivars to
reach semi ripe stage and 214.17 and 210 days to ripe stage of harvesting respectively. Frontoio, Ottobratica and Pendolino
attained semi ripe stage after 180.17 (11th October), 184.50 (20th October) and 193 (22nd October) days respectively, while
188 (19th October), 195 (30th October) and 203.67 (2nd November) days were taken by these cultivars to attain ripe stage of
harvesting after flower opening. The cultivar Manzanilla produced heavy fruits (4.34 g), however large sized fruits (4.48
cm3
) with more pulp: stone (4.94) were yielded by Picual. High fruit yield (35.81kg tree-1
) and more oil percentage
(14.66%) were determined in the oil extracted from fruits of Frontoio. Yield and yield components enhanced from lemon
green to semi-ripe and ripe stage of harvesting, also the percentage of oil increased with the ripening process of olive
fruits. Olive cultivars Frontoio, Manzanilla and Picual are recommended for high yield and production of olive oil.
