Abstract
This investigation was carried out during three successive seasons i.e. 2003, 2004 and 2005/2006 on Sewy date palm, grown in a private Orchard at El-Dakhla Oasis, New valley, Egypt, where the soil is sandy loam. This was carried out in three experiments.
The first experiment:
The main objective of this experiment is to find out an additional information concerning the seasonal trend of producing new leaves and annual production of inflorescences. Additionaly, the tendency to the irregular bearing. Ten date palms were arranged in randomized complete design with the replications of one palm each.
The following measurements were determined during the three studied seasons:
1- The new leaves were tagged and counted every 3 months (season of year) interval starting at March 21st, 2003, along the year till December 21st and continued throughout three successive years till March 2006. Thus the final count represents leaves of 3 months old, then the number of producing new leaves along the year was counted.
2- The percentage of leaves embracing by inflorescences relative to the total number of leaves of the same age.
3- The percentage of contribution of the productive leaves of different ages in the final production of inflorescences per palm.
4- The irregular bearing index.
The second experiment:
The aim of this study shade more light on the beneficial effects of organic manure singly or combined with inorganic fertilizers on growth,
