Abstract
The influence of biogas manure produced from anaerobic digestion of fresh cattle dung on the recovery of root-knot disease and vegetative growth of tomato plants was investigated. The digested slurry (biogas slurry) was used directly or after being air dried (biogas manure). Dried biogas manure was incorporated into the soil 3 weeks before transplantation at the rate of 120 mg N kg-1 soil, while biogas slurry was added in two equal portions, 60 N kg-1 soil, at transplantation time and one month later. The two types of biogas manures induce significant increase in the growth of tomato plants when compared with non-manured one. The highest NPK uptake was shown in the healthy manured plants. Biogas slurry have the most stimulative effect on the microbial counts and enrichment of the soil with ammonia than dried biogas manure. Both types of biogas manures were effective in decreasing the number of galls induced by Meloidogyne javanica. However, biogas slurry was more effective, in reducing disease and in improving the chemical and biological properties of the soil, than dried biogas manure. This was attributed to the high content of biogas slurry of both easily decomposable organic matter and available nutrients.
