| Abstract | ||||
| TLi:! present work was carried out at Salhia, Sharkia Governorate, Egypt during 1998/99 and 1999/2000 seasons. Fennel plants were sprayed with methionine at the rates of 0,50,100 and 200 ppm with or without three concentrations of zinc (as zinc sulphate) 0,50 and 100 ppm. Plants were sprayed twice during the season with methionine and zinc . The results indicated that application of methionine reduced plant height, chlorophyll content, soluble sugars and nitrogen content. While, methionine at 100 and 200 ppm increased number branches and umbels 1 plant, fruits yield, essential oil yield , total carbohydrates, P and K contents. Generally, application of zinc showed positive effects on growth, yield and chemical constituents of fennel. The combination between application of methionine at 100 ppm and zinc at 50 ppm increased significantly essential oil and fruits yield compared to control. While, the highest values of branches and umbels number 1 plant, essential oil yield and percentage; total carbohydrates and phosphorus contents resulted from spraying of methionine at 100 ppm combined with zinc at 100 ppm. | ||||
