| Abstract | ||
| This experiment was carried out in Kirkuk governorate / Hawija district for the period from 2018 to 2019, using the design of the complete random sectors according to the split-split-split-split system with three replicates (Split-Split-Split Plot design in RCBD.), And the first factor was the dates of the insects, The second factor was control treatments, the third was seed rates, while the fourth factor was organic fertilizer. The results showed that the highest ratio of leaves to stems was 39.4% at the fourth stroke, and the highest proportion of the dry matter ratio at the first stalk was 15.57%, and the average of the first stalk gave the highest protein ratio 17.56% and thus outperformed all the stems, the ratio of leaves to stems increased The dry matter and the percentage of protein by spraying weed herbicide were significantly, with the highest percentage reaching 41.72%, 14.25% and 14.70% for the studied characteristics, respectively. The highest ratio of leaves to stems was 39.43% at the high seeding rate, as well as the highest percentage of dry matter 14.02% at the rate of 36 kg.h-1. This increased the protein percentage to 14.90% at the same high seed rate. The ratio of leaves to stems was significantly affected when adding fertilizer at a rate of 40, 80 tons. h-1 and reached 36.92 and 38.93%, respectively, and the highest percentage of dry matter was 13.91% when treating 80 tons h -1, while the lowest percentage of protein when treated without fertilizer was 14.68 %. As for the overlapping of all factors, the largest ratio of leaves to stems was 51.82, 52.00% for my treatment (fourth seed + herbicide+ 36 kg.h-1 + 40 tons.h-1) and (fourth piece + 36 kg.h-1 + 80 tons.h-1 In a row, and thus, these two treatments were significantly superior to all quadruple interference factors, a moral superiority was seen when treating (first seed + herbicide+ 36 kg. h-1 + 80 tons. h-1) and it reached 19.96% as the highest percentage of protein when all the factors studied overlapped. | ||
