تأثير الرش بالهرمون "كليباك" و المغذي Vit. Org الحيويين في نمو و حاصل صنفين من الخيار الهجين Cucumis sativus L. المزروع في البيوت البلاستيكية غير المدفأة

Abstract EN

An experiment was conducted during the Agricultural winter seasons of 2011 / 2012 in unheated plastic house at the College of Agriculture.

Basrah University.

The aim was to study the effect of spraying with bio hormone (Kelpak) and Vit.

Org.

on growth and yield oftwo cucumber vars.

"Sara" and "Saif".

The experiment included eight treatments which is the combination resulted from the interaction between spraying with and without for both Kelpak and Vit.

Org.

and two varieties of cucumber.

Results can be summarized as follows : Sara plants gave significant increases in total leaf number / plant, decrease days for first inflorescence opening, total flower number / plant, total fruit number / plant, fruit weight (103.4 g), fruit yield / plant (3.133 kg) and plastic house productivity (1349.0 kg).

Whereas, Saif plants gave significant increases in chlorophyll content of leaf only.

Plants sprayed with bio hormone (Kelpak) gave significant increases in plant height, chlorophyll content, decreased days for first inflorescence opening, total fruit number / plant, fruit length, fruit diameter fruit weight (101.3 g), fruit yield / plant (3.690 kg) and plastic house productivity (1307.0 kg).

Whereas, plants with out spraying gave significant increase in carbohydrates content.

Plants sprayed with Vit.

Org.

gave significant increases in carbohydrates content, decrease days for first inflorescence opening, and fruit set.

Total flower number / plant.

total fruit number / plant, fruit diameter, fruit weight (104.3 g), fruit yield / plant (3.106 kg) and plastic house productivity (1366.0 kg), whereas, plants with out spraying gave significant increase in tota soluble chlorophyll content.

The interaction between the studied factors gave significant increases in all studied parameters.
