“…These results are in harmony with those of Rodríguez et al (2004), who found that citrus tree growth was lower at short distances in comparison with greater planting distances. On the contrary, Intrigliolo et al (1994) mentioned that 'Valencia' orange trees planted at closer spacing (5 x 3 m) gave the largest canopy, compared with the standard spacing of 6 x 4 m. 3.1.4.…”

“…In addition, Intrigliolo et al (1994) showed that 'Valencia' orange trees in closer planting (5 x 2.5 m) produced a 123% increase in yield/ha compared with standard spacing. On the other hand, Rodríguez et al (2004) reported that the yield of citrus trees was increased proportionally to the increase in the number of trees per unit of area during the first years, and later went similar or superior to those obtained at shorter distances.…”

“…However Intrigliolo et al (1994) reported that the mean yield/tree of 'Valencia' orange was higher in trees at the closer spacing (5 x 3 m). On the contrary, Rodríguez et al (2004) found that citrus tree production was lower at short distances in comparison with greater planting distances, and Nasir et al (2006) mentioned that trees of grapefruit in wider spacing (7 x 7 m) produced higher yields during the first 3 years of production than those in the close spacing (7 x 3.5 and 3.5 x 3.5 m).…”

Hernandina' clementine, 'Clemenules' clementine and 'Nova' mandarin budded on sour orange rootstock were produced in a screenhouse and planted in the field under drip irrigation system during October 1999 in a private orchard at "Wady El-Mullak" region, Ismailia Governorate (Latitude, 30°36' N; longitude, 32°14' E; Altitude, 10 m above sea level), which is one of the largest citrus production region in Egypt. All cultivars were planted at 2 x 5 m and 5 x 5 m. Annual fruit production, cumulative and average yields per tree and per feddan were estimated during five seasons, starting from 3 rd year after planting (YAP) to 7 th YAP (2006YAP ( /2007. Tree height, canopy diameter and circumference, tree volume, and trunk girth were determined in the 6 th and 7 th YAP.Trees planted at 2 x 5 m were the tallest, but the canopy diameter and circumference, and volume of trees planted at 5 x 5 m were the largest. On the other hand, trees of 'Nova' mandarin had the lowest canopy diameter and circumference, while 'Clemenules' clementine trees had more height and volume.Initial yields per tree (3 rd and 4 th YAP) from planting spacing of 2 x 5 m were higher than those from the wide spacing, but starting from 5 th to 7 th YAP the situation was inverted. Cumulative yield for the first 5 years of production and the average annual yield per tree revealed the superiority of the wide spacing. On the contrary, the yield per feddan (4200 m 2 ) from trees planted at 2 x 5 m was about 454%, 221%, 137%, 76% and 90% greater than those planted at 5 x 5 m in the 3 rd , 4 th , 5 th , 6 th and 7 th YAP, respectively. Cumulative yield per feddan from closely planted trees was 40 t (117%) more than from widely spaced.'Hernandina' clementine produced more yields in the 3 rd and 4 th YAP compared with other cultivars; while 'Clemenules' clementine was the highest in the 5 th YAP. 'Nova' mandarin produced the highest yield in the 7 th YAP, while in 6 th one were statistically similar to those of 'Hernandina', which produced the highest yield. Cumulative and average annual yield per tree indicated that 'Hernandina' and 'Nova' cultivars were more productive than 'Clemenules' under the conditions of this study. On the other hand, 'Clemenules', 'Hernandina' and 'Nova', as new citrus cultivars in Egypt performed satisfactory in a highdensity planting (2 x 5 m) through 7 year after planting, despite of 'Nova' mandarin was the most excellent, followed by 'Hernandina' and 'Clemenules' (cumulative yields were 82, 71 and 68 t/feddan, for the three cultivars, respectively); and could continue until the productivity per feddan decrease compared to normal spacing.
