| Abstract | ||
| This study was carried out to dear the role and importance of two planters of sugar beet on yield and quality. The field experiments were carried out at Sakha Agric. Res. Station at Kafr 9-Sheikh Governorate in two successive seasons 2001/2002 and 2002/2003. Two planters (Tabata and Hassia planting machines) with three forward speeds (4.7, 6.5 and 7.7 km/h.) and one, two and three hoeings were used in this study. The main results can be summarized in the following points: -Number of plants per feddan were38058, 32157 and 26846 in the first season and 37471, 30944 and 25825 in the second season for Tabata planting machine with forward speeds of 4.7, 6.5 and 7.7 km/h.. While, the number of plants with planting machine Hassia at the same speeds was 34608,29232 and 25378 in the first season but, in the second season was 34167,28870 and 24452 plants/fed., compared with manual planting which were 20814 and 21723 plants/fed. in both seasons, respectively. -Sucrose percentage deceased from 15.98 and 16.42 to 15.62 and 16.10 % in both seasons with Tabata and Hassia planting machines, respectively with increasing forward speed from 4.7 to 7.7 km/h.. This decrease is due to wide space between plants, which compared with high speed, resulted in big roots with small sucrose percentage. Sucrose percentage attainted to increase the hoeing times compared with one and two hoeings. -Root yields significantly increased with Tabata planting machine at low speed of 4.7 km/h. (30.521 and 31.217 ton/fed) at 35 cm plowing depth and three hoeings in both seasons, compared with Hassia planting machine which recorded 28.317 and 29.707 ton/fed. in both concerts under the same condition or the manual planting which recorded the lowest root yield in both seasons 12.168 and 13.470 ton/fed with one hoeing. | ||
