| Abstract | ||
| A field experiment was conducted in sandy clay soil through spring and autuman season of 2012 in AL-Habannnia island / AL-Anbar descrite to study effect of four levels of nitrogen fertilizer ( 0 , 75 , 150 and 225 kg N.h-1 ) and harvesting dates ( 50 % flowering , after 10 days and after 20 days from 50% flowering ) in number from of quality traits in green forag of Sorghum . factorial experiment system in R.C.B.D. design was used in this study with three replicates . The third fertilizer level was superior for two dates of cutting in two seasons by crude fiber yield and the fourth level was superior in percentage of crud protien ( 11.69 , 11.64 , 12.16 , and 12.05 % ) respectively and and crude protein yield and percentage of crude fiber and percentage of the ash . The third date of cutting was superion in percentage of total charbohydrates (10.81 , 10.78 , 9.74 , 9.75 % ) respectively , and crude protein yield and crude fiber yield for two cutting in spring season , and first cutting for autuman season . The interaction was significant in studied traits of both harrsting dates and seasons. | ||
