| Abstract | ||||
| The present work was conducted in three field trials that were separately earned out in two successive seasons dump 1995/1996 and 1996/1997 at upper Egypt to fad out the relative advantage of some cultural practices to yield and quakty attnbutes of sugar beet. The 151 experenent included 14 treatments which were the cornbnation between two sugar beet varieties and 7 sowing patterns. The 2nd experiment included 10 intercropping treatments representing the various combinations between two sugar b •et vareties and (we inter-cropping patterns. The 3W trial consists of 15 treatments which were the combinations betwen three levels of boron (zero 'potation. 0.5 and 1 kg.8./led.).and five levels of zinc (zero application. 1.2.3 and 4 kg. Znifad.). The important results mild be summarized as follow:- Sowing sugar beet plants as usual in rows 50cm. between rows and 20 and/or 25cm. between hills attained the highest sugar beet MIS yield. Moreover. increasing the plant population per unit area by sowing sugar beet in the two sides of banks (1 m. in width), in addition to one more row en the mddle of the bank and 20 cm. between Nib re-corded the highest values of pace punty and sugar yield. Cultivating intercroptang onion with sugar beet (75), significantly lowered sugar beet yield. However. companion onion with sugar beet at-tamed an additional income represented in the total .ncome 4.1 tons en-ion (LE. 3200). in addition to the total revere& of the beet itself (LE. 1883). kleanwele, the highest pure stand 01 sugar beet produced 31.4 tons/fad. attaining total profit (LE. 2198). Ape:eaten of 1 kg.13./fad. produced 4.9 ton/fad. over unfertilized treatment. This increase was too limited (1.3 ton/fad.) over check treatment when Zn. element was apa plied by Ikg.znifad. A ;axonal factor analysis was performed to analyze the relationship between ten vanables of sugar beet in thee experiments for two cultivars. Soh and Hama in a two success& . seasons during 1995/96 and 1996/97 at Shandaweel Research Station in Sohag Governorate. These variables were also used in a stepwise multiple linear regress°, to study the relationship between them and sugar yield to construct a general equation for predicting yield. Factor analysis indicated that root length. sucrose, purity and sugar yield were the most important in the three experiments. Factor | ||||
