Abstract |
During winter of 2003-2004 a field experiment using Egyptian clover (Trifolium alexandrinum) was conducted at a private farm of Ahmed Orabi village, southern Tahrir province, Al-Behaira Governorate, to study the influence of clover seeds soaking in different Se concentrations as well as foliar application on clover Se concentration and crude protein. The used treatments were: (1) soaking seeds process: The seeds were soaked for one hour in solutions having Se concentration of 0, 500, 750, 1000, 1250 and 1500 mg Se kg-1 seeds as sodium selenate. The appropriate quantities of sodium selenate to 40 g seeds (24 kg seeds/fed.) were dissolved in 50 ml distilled water and soaked. (2) Foliar application: Selenium as sodium selenate was added at rates of 0, 2, 4, 8, 16 and 32 g Se/fed after 5 weeks from germination. These concentrations were dissolved in distilled water and sprayed at the application rate of 250 L/fed. The treatments were arranged in a completely randomized block design with three replicates. The clover plants were harvested in three cuts.
The obtained results could be abstracted in the following:
• Selenium concentration in berseem plants, which enriched by Se as sodium selenate through soaking of seeds or foliar spray, was significantly and positively affected with increasing rates of Se application.
• Selenium concentration in plant tissue was higher in the first cut than the other ones. However, the Se application through foliar spray resulted in berseem plants having Se concentration higher than soaking treatments especially at the treatments of 16 and 32 g Se/fed.
• Foliar application of 8, 16 and 32 g Se/fed was more effective on Se content in cut-1 of berseem plants than the other applications and other cuts. The low level of Se soaking and foliar applications were the lowest one on their effect on tissue Se-content. Se concentration in cut-2 and cut-3 were similar under soaking and foliar application.
• There was no consistent effect of selenium treatments as soaking of berseem seeds or foliar spray on crude protein. Crude protein (%) of berseem plants was significantly affected with the successive cuts irrespective of Se treatments
