الملخص الإنجليزي

An experiment was conducted at the house covered with saran in the nursery of the Faculty of Agriculture University of Kufa during the growing seasons of 2016-2017 to study effect of spraying extract of organic fertilizer and ascorbic acid on growth and flowering parameters of freesia plants and its flower content of carotene pigment.

Experiment was adopted a Randomized Complete Block Design (R.

First three concentration of extract organic fertilizer i e.

(0, 5 and 10ml.

Second three concentration of ascorbic acid i.
