Field experiment was conducted during the growing season of 2009/2010 in Babylon Governorate, to study the effect the addition of Ammonium Sulphate fertilizer at three levels 0, 75 and 150 Kg N.ha-1 and Pinching at three levels 0 (with out pinching), 35 and 50 days after planting on growth, seeds production and their contents of some active constituents for Local Rocket Eruca sativa Mill., The treatments were distributed on factorial experiment conducted at Randomized Completely Block Design in three replicates.

Means were compared according to the Least Significant Difference test at the level of 0.05.

Results showed significant effects for Ammonium Sulphate fertilization at level 150 Kg N.ha-1 in all studied characters and an increased percentage for seeds production, oil percentage, glucosinolate, glutathione, total phenolics and total Flavonoids were 26.29, 18.94, 16.90, 5.19, 16.33 and 10.65 % respectively.

Results also showed significant effects for pinching after 35 days for planting and gain high means on number of leaves.plant and fresh weight, While pinching after 50 days for planting gain high means on number of secondary branches.plant and dry weight as will as gain an increase percentage for seeds production, oil percentage, glucosinolate and glutathione at 10.16, 10.39, 6.39 and 2.64% respectively, Interactions between the two factors were significantly affected on all studied characters.
