Abstract
This experiment was conducted in Faculty of Agriculture nursery, at Shambat to study the effect of nitrogen and chicken manure fertilization on herbage yield and oil content of the spearmint (mentha spicata) during the season 2005-2006. Six treatments were used in this study, 2N, 4N nitrogen in the form of urea, 2.5, 5 tons/fed chicken manure and 2N nitrogen+2.5 ton/fed chicken manure and a control. The results show that, there were no significant differences among the different treatments on the growth parameters and oil content. On the other hand the results show a significant difference among the different treatments on the fresh and dry weight of shoots and the roots. Also the results show that the higher fresh weight was at the 2N treatment (274.97 g) while the lower fresh weight in the 4N treatment (113.93 g). Higher dry weight was in the 2N treatment (62.7 g) and the lower dry weight in 2N nitrogen+2.5 ton/fed chicken manure (32.17 g), also higher root weight was in 2N treatment (132.433 g) and the lower root weight in 4N treatment 107.10 grams.
