تأثير السماد العضوي "نيوترغرين" في بعض صفات شتلات الزيتون صنفي Manzanello و أشرسي

Abstract EN

This study was carried out from 1/3/2013 to 15/10/2013 on Olive transplants (Olea europea L.

) cvs.

Manzanello and Ashrasi which were cultivated in polyethelen bags in lath hause / Horticulture Dept.

/ Colloge of Agriclture and Forsetry / Mosul Univ.

/ Iraq.

The transplants were fertilized with four levels of liquid organic fertilizer (Neoterogreen): (0, 2, 4 and 6) ml.

l-1 which were added at five doses (first from the months: May, June, Juluy, Auguest and Septemper) with 200 ml.

transplant-1 for each concentration.

The treatments were arranged with Randomized Compleat Block Design (R.

C.

B.

D).

The data was stasticaly analyzed and the means were compared by Duncan multiple range test at 0.05.

Results indicated that the cultivars did not differ significantly on all studied parameters except the increament of main stem diameter which were Ashrasi cv.

superior on Manzanello cv.

, meanwhile adding organic fertilizer caused a significant effect on all studied paramenters, where fertilization with of 4 ml.

l-1 of Neoterogreen gave the highest means of leaves N and carbohydrates concentrations, while fetilizing with this fertilizer at a concentration of 2ml.

L-1 gave the highest means of the increament of main stem diameter, Meanwhile the concentration of 6 ml.

l-1 gave the highest values of roots dry weight.

The interaction between cultivars and Neoterogreen organic fertilizer significantly effected on all studied traits.
