This study was carried out at Abu- 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 cultivar is , in Randomized Complete Block Design(RCBD) with 3 replication. The results were 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. |
