تصنيع جهازان لتلقيح و تعفير النخيل و تقييم أدائهما على صنفي الساير و الحلاوي في محافظة البصرة

Abstract EN

Two automatic devices for pollination and fogging of date palm were designed and manufactured at the department of Agricultural Machinery, College of Agriculture, University of Basrah.

They were date palm pollination and fogging device fig.

1 and the developed device fig.

2.

Their performance was field tested at a private field in Al-Hartha township, Basrah Governorate at two seasons 2013 and 2014 using CRBD design in a factorial experiment with three replicates.

The study included the application of automated pollination using the two devices in comparison with manual pollination on Sayer and Hilawe varieties.

The following properties were studied: percentage of fruit setting, fruit length and diameter, fruit and flesh weight, total yield and actual productivity of pollination (tree.

h-1).

The results demonstrated the significant superiority of manual pollination in percentage of fruit setting in comparison with automated pollination with the two studied devices.

Pollination device fig.

1 and the developed device fig.

2 significantly surpassed the manual method in fruit length and diameter and fruit and flesh weight.

The two methods of automated and manual pollination do not show significant differences in tree productivity (Kg.tree-1) while the two studied devices showed considerable superiority of 160% in the actual productivity of pollination (tree.

h-1) in comparison with the manual method.
