| Abstract | ||||
| A field experiment was conducted during winter seasson of 2005/2006. Egyptian berseem (Trifolium alexandernium) was used as a forage crop. The selenium treatments of foliar spray were added at rates of 0, 4, 8, 12 and 16 g Se fed-1, as sodium selenate (Na2SeO4 ). Each level of selenium was divided into two doses i.e. 0, 2, 4, 6 and 8g Se fed-1 . The cut 1 and cut 2 were sprayed while cut 3 was left without spray. The selenium treatments of soil application were added at rates of 0, 12, 18, 24 and 30g Se fed-1. The berseem plants were harvested in three cuts. There were no significant differences between dry matter yield of berseem plants and selenium levels of both foliar spray and soil application. The dry matter production was slightly increased with increasing Se levels of foliar spray but it decreased with increasing Se levels of soil application. Se- concentration in berseem plants was increased with increasing selenium levels of foliar and soil application. The relative increase in Seconcentration in case of foliar spray was 1015% as the Se levels increased from 0 to 8g fed-1, while in case of soil application, they were 821% when Se levels increased from 0 to 30 g Se fed-1. Seuptake by berseem plants increased with increasing selenium levels of foliar and soil application. The relative increases in Seuptake for foliar spray and application were 1042% and 720%, respectively. | ||||
