Abstract

Two  field trials were carried out in west Nubaria district, throughout two successive seasons of 2016/2017 – 2017/2018 to evaluate multiple strategies based on reducing the interval between seeding and seedling emergence, by increasing the speed of germination and seedling emergence to offer the most important escape strategy from soil-borne pathogens, the acceleration of germination and plant emergence and sometimes the improvement of seed viability and the acceleration of seedling growth was done by means of what so called EPD (Early Plant Development or fast initial growth) under protection using certain nematicides. Along with those field trials, pot experiment was done at outdoor for 60 days to assess host suitability (resistance) designations of studied varieties i.e. Beta vulgaris subsp < em>. Vulgaris, Sahar var. and Helsinki to root-knot nematode, Meloidogyne incognita. Experimental design was a factorial arranged split-split plot with variety as main plot, plowing depth as split plot in the form of strip-plot arrangement of six treatments and treatment as split-split with four replicates was used. Quantitative scheme for assignment of Canto-Saenz's host suitability for root-knot nematode showed that sugarbeet variety, Helsinki is tolerant and Sahar variety is susceptible. Evaluated treatments i.e. strategies were varied combinations their components consisted from EPD, Abamectin, Oxamyl 10% G and Nemastop and were compared with control treatment. Analysis of variance for the combined data of the studied two seasons significantly at P ≤ 0.05 marked out the effect of various treatments. Studied Treatments impact individually or in combinations on root-knot nematode parameters, as nematodes number/g soil, knot disease severity % and drop rate % results indicated that sugarbeet variety Helsinki overcame Sahar variety positively for the abovementioned parameters; also, 30 cm-plowing depth outperformed the other two depths in the same issues. Managements treatments distinctly revealed that (EPD + Nemastop), (Nemastop) and (EPD) achieved the best results to reduce all studied root-knot nematode parameters Most likely with a plowing depth of 30 cm. Individual treatments showed that at the level of variety, monogerm Helsinki outperformed polygerm variety, Sahar in all abovementioned parameters. At plowing depth level, 30 cm-plowing depth was mostly had superior positive effect on all recorders. At the level of treatments, (EPD + Nemastop) had a distinguish effect on root and sugar yield per fed., sugarbeet variety, Helsinki overcome Sahar variety. Also, 30 cm-plowing depth had the lead in achieving preferred results, as well treatments (EPD + Nemastop), (Nemastop) and (EPD). Interactions of combined treatment as well showed distinguished results for those parameters mentioned above as combined treatments implied one of those distinguish individuals. Interaction effect of combined treatments got promising results as they implied any of individual treatment that previously showed positive results concerning the same nematode parameters.
