An innovation for organic crop production by compost fertilizer of Isfahan municipal’s waste as bionematicide and biofertilizer

摘要

Sugar beet cyst nematode (SBCN), Hederodera schachtii Schmidt. 1871, marked as one of the most damaging disease of sugar beet fields worldwide. Non chemical controls measures were carried out, using organic fertilizers including farm, poultry and green manure (waste cabbage leaves), compost (municipal’s waste products, 0.15 and 0.08?mm in size) and vermicomposting as the soil treatments at various rates against control (no treatments) in glass house and field highly infested with the nematode, SBCN in Isfahan, Iran. The related data on cysts final population, number of eggs and second larvae per cyst and per gram of soil were subjected to statistical analysis. The reproduction factor and the percent reduction and or increasing in population of nematode, SBCN were taken into consideration in comparison to initial populations. The results revealed that, poultry manure at the rate of 40 t?ha -1 had the most and highly significant effects on the final population reduction in contrast to other ones, including controls. Followed by 0.15mm (60?t?ha -1 ), compost 0.08 (60?t?ha -1 ), poultry manure at the rate of 20 t?ha -1 , with no significant differences respectively. Vermicomposting, cabbage leaves and form manure treatments had the least effects on the final population reduction in sugar beet cyst nematode populations.
