The unpuddled transplanted rice gives yield similar to that of puddle transplanted rice (Haque, 2009 Saharawat et al., 2009). Very recently, seedling transplanting is done in unpuddled land just after strip tillage (a form of conservation tillage that clears crop residues in a narrow zone of soil and loosen subsoil layers prior to planting, Mitchell et al., 2009) followed by irrigation. Rice is generally grown by seedling transplanting on puddle land to facilitate easy crop establishment and weed control. Oleuropein content of The leaves and pruning residues were measured at flowering phenological stage. The main objective of the present research is to investigate the effect of water regimes and fertilization with urea (over than the rates recommended by the Ministry of Agriculture) on Oleuropein content of leaves and pruning residues The treatments were T1 : control (farmer " s conventional technique of irrigation and fertilization), T2 (75% of ETc by drip + 1% urea), T3 (75% of ETc by drip + 2% urea) T4 (75% of ETc by bubbler + 1% urea), T5 (75% of ETc by bubbler + 2% urea), T6 (60 % of ETc by drip + 1% urea), T7 (60% of ETc by drip + 2% urea), T8 (60% of ETc by bubbler + 1% urea), T9 (60% of ETc by bubbler + 2% urea) and two level of urea (1 and 2kg/100 liter) were injected through the irrigation system during March over than the fertilization rates recommended by the Ministry of Agriculture. His work was conducted for two successive seasons (2015/2016) on Shemlaly 15 years old olive trees (Olea europaea L.) cultivated under semi-arid conditions of Egypt (sandy soil at spacing of 4x5 m) at a private orchard located in Cairo–Alexandria desert road, The tested trees were almost uniform in growth vigor, healthy, subjected to drip irrigation and received the same culturel practices adapted in the region such as fertilization, irrigation, pruning, and hoeing as well as pest management.
