This study was conducted at Mosul university compus. The samples were collected from four species of forest trees)<em>Ceratonia siliqua </em>, <em>Robinia pseudoacacia</em>, <em>Morus</em> <em>alba</em> ,<em> Leucaena leucocyphala</em>(in nine dates namely (1/4 , 1/5, 1/6, 1/7, 1/8 , 1/9, 1/10, 1/11, 1/12).The characters (Chlorophyll A, Chlorophyll B, Chlorophyll AB , dry matter , crude protein , crude fiber)were studied to find the correlation relationship percent between Chlorophyll quantity (A,B,AB) and percentage of (dry matter,crude protein , crude fiber) to create prediction equations for calculate these three characters. The study showed significant differences between species , dates and its interaction in all the studied characters. <em>Leucaena leucocyphala</em> trees significantly superiority in (Chlorophyll A, Chlorophyll AB , crude protein and less quantity of crude fiber) characters, first date (1/4) was significantly superiority in(Chlorophyll A, Chlorophyll B, Chlorophyll AB, crude protein and less quantity of crude fiber). There were significantly correlation between dependent variables ((dry matter,crude protein , crude fiber) and independent variables (Chlorophyll A, Chlorophyll B, Chlorophyll AB) , through this strong correlation we created nine equations represent the relation between these dependent and independent variables. The best equation (Crude protein = 18.4656 - 17.9462*1/x₃) to find crude protein percentage depending on overturnedtotal chlorophyll.
