| Abstract | ||||
| Two investigate field experiments the effect of four preceding crops (maize, sunflower, sesame and soybean) on growth and yield of sugar beet and the effect of the remnants of the previous crop of roots, leaves and stems residues on the root nematodes of sugar beet were carried out at Mallawi Agricultural Research Station, Minia Governorate, ARC, during two successive winter seasons 2016/2017 and 2017/2018 in a highly and naturally infested field with nematode. The result showed that the highest roots yield were recorded when sugar beet planting in place of soybean roots (37.98 ton/fad) followed by planting sugar beet in place of all sesame crop residues (36.89 ton/fad).Planting sugar beet in place of maize crop roots only or all residue where recorded minimum sugar beet roots (25.07 and 26.93 ton /fad), respectively. Highest sugar yield were observed when planting sugar beet in place of soybean crop roots only or sugar beet in place of all soybean crop residues(5.84 &5.08 ton/fad), respectively). The lowest value of surviving plants % were obtained when sugar beet planting in fallow lands (control) and planting sugar beet in place of maize crops roots only and all residues (68.39,68.45& 69.89%)respectively. It could be summarized that the redoes of the crop was to the loses a large number of tubers due to infection and death by plant nematodes. Sowing sugar beet revealed some increment in all nematode genera numbers that recorded the lowest number from sugar beet planted in the place of all sesame crop residues. | ||||
