| Abstract | ||||
| Two field experiments were carried out in km 71 West Alexandria- Cairo desert Road during 2014/15 and 2015/16 seasons to study the response of some multigerm sugar beet varieties i.e., Top, Sultan and Kawemira to foliar spray with compost tea at three levels of (0, 15 and 20 L/fed/300 L water) at 45 and 75 days from sowing. The experimental design was a split plot design with three replicates, foliar spray with compost tea levels were arranged in the main plots and sugar beet varieties were allocated in the sub plots. The results showed that foliar spray with the level of 20 L/fed with compost tea significantly increased root length, diameter, fresh weight/plant, sucrose%, purity%, root and sugar yields/fed in both seasons, while, decreased root mineral contents (α amino N, Na and K %) as compared with zero treatment (control) or 15 L/fed level of compost tea. The Three tested varieties were differed significantly in the root length, diameter, fresh weight/plant, sucrose%, purity%, root and sugar yields/fed and root mineral contents. Kawemira variety surpassed the other two varieties (Sultan and Top) in the most traits in both seasons. Foliar spray with compost tea increased the numbers of two sugar beet insects,beet fly (Pegomya mixta Vill.) and tortoise beetle (Cassida vittata Vill.). Kawemira variety was less attracted by the two previous insects, during two successive seasons. Moreover foliar spray with compost tea at level 20 L/fed recorded the highest values for sucrose %, root and sugar yields/fed in both seasons. Generally, it could be recommended that sown Kawemira, Sultan and Top varieties, respectively and sprayed with 20 L/fed compost tea produced the highest sucrose%, root and sugar yields/fed and yield quality in a sandy soil. | ||||
