| Abstract | ||
| The experiment was conducted in lathhouse of Agriculture college during growth season 2013 to study the effect of four concentration of urea (0 , 0.40 , 0.70 and 1)% and two dates of application 1/2 , 1/3 and their interactions on physical and chemical characteristics of citrus seedling. The results were induction that foliar spray of urea fertilization had significant effect in creasing of studies properties. The 1% treatment gave higher average of vegetative properties like heist of plant, length of branch, number of branches, number and leaf area 131.50 cm, 39.25cm, 7.67, 43.50 and 21.61cm2 respectively and gave higher average of chemical characteristics like dry weight of leaf and leaves content of total chlorophyll 62.67% , 0.680mg/gm fresh weight. Statistical analytical and total nitrogen of leaves results showed that were a significant differences between the date of urea application, the second time of application was significantly increased studied properties compared with efforts data of foliar spray. So the interaction between urea application and the time of foliar spray had significantly increased the studied characteristics and 1% urea application, second time treatment gave higher average of studied characteristics compared with other treatment. | ||
