This study was carried out atAbu- Graib research station ,Collage of
Agriculture,Baghdad , during early spring 2004,in order to determine the effect different Urea (46%N) concentration (0.10.20 gm N/L) on transplants of five jujube cultivaris , in Randomized Complete Block Desgin(RCBD) with 3 replication.
The results was summarized as below:-
** Cultivar Factor : the local cultivar ( Al-Bathry) gave the heights number of leaves (88.66) while (Zaituni cv) gave biggest leaves area , leave length and width (12.5 cm ,5.93 cm, 3.3cm consequently , while
(Tuffahy cv) shows the heights fresh & dry leaves weight(4.83 and 1.82 gm) consequently .
**Nitrogen Concentration:- the result revealed that the seedlings treated with 20 gm N was significantly increased in all cultivars, in all parameters studied.
** Interaction factors (cv x N concentration) :
The results shows that the (Bathry ) cultivars gave the height leaf number at 20 gm nitrogen ( 91.00 leaf/ plant ) while ( Zaituny cv).gave the biggest leaf area at the same treatment (14.91 cm)and the leaf length , width (7.8and 4.4 cm) consequently , but( Tuffahy cv.) gave the heights fresh and dry weight at the same treatment ( 5.3, 2.3 gm ) consequently. |
