EFFECT OF VARIETY AND – FERTILIZER CONCENTRATION ON SAME VEGETATIVE GROWTH CHAR OF JUJUBE PLANT

Abstract

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.
