اثر برخی از کودهای آلی و زیستی در کاهش جمعیت نماتد مولد گره ریشه (.Meloidogyne spp) روی انار

One of the most important pathogens in plants such as pomegranate, are root-knot nematodes (Meloidogyne spp.) which cause considerable damage to this important export product. Due to the importance of this subject, an study has been conducted between ۲۰۱۸ and ۲۰۱۹ in the Faculty of Agriculture of Lorestan University. The treatments include organic fertilizer (۴۰, ۶۰, and ۸۰ t/ha.), vermicompost (۴۰ t/ha.) and Marygld product (۲۰۰, ۳۰۰ and ۴۰۰ g/m۲) with the study, itself, being in a completely random design on the dominant root-knot nematodes species, M. javanica under greenhouse conditions on pomegranate seedlings. The measurement indicators include gall index, the number of egg sacs, and the final population of egg and J۲ larvae in the soil and the roots, as well as growth factors of pomegranate seedlings. Reproduction factor and the percentage of increase/decrease of root knot nematode population, have been calculated in each treatment compared to the initial population of the same treatment. Results show vermicompost (۴۰ t/ha.) with ۹۴.۳۵% reduction in population of egg and larvae has had the highest effect on reducing the nematode population compared to other treatments. Marygld ۴۰۰, ۳۰۰, and ۲۰۰ g/m۲ treatments are ranked next, with a reduction of ۹۳.۴۷%, ۹۱.۲۱%, and ۹۲.۶۵% in nematode population, respectively followed by by nematode reduction of the composts of ۸۰, ۶۰, and ۴۰ t/ha by ۸۹.۶۷%, ۸۶.۵۵%, and ۸۶.۸۱% respectively.
