Impact of liquid chicken manure preparation on biodiversity of nematodes in wheat

Abstract

Cilj ovog istraživanja bio je utvrditi utjecaj preparata na bazi tekućega pilećega stajnjaka na biološku raznolikost nematoda kao pokazatelja zdravlja tla. Pokus na terenu proveden je kroz dvije godine u dva tretmana i tri uzorkovanja godišnje. Jedna parcela tretirana je preparatima na bazi tekućega pilećega stajnjaka (Ekobooster i Ekovital) , dok je druga bila kontrolna. U prvoj godina pokusnim parcelicama bila je zasijana pšenica. Rezultati pokazuju da je bioraznolikost rodova bila značajno brojnija u tretmanima s preparatima (Ekobooster i Ekovital). Indeksi uznemirenja (MI, MI[2-5], PPI/MI) pokazuju statistički značajne razlike kroz dvije godine te upućuju na stabilnost ekosustava, smanjenje fitoparazitskih nematoda i mnoštvo korisnih nematoda u tretmanu usporedno s kontrolom. Može se zaključiti da upotreba preparata na bazi tekućeg pilećeg stajnjaka značajno povećava biološku raznolikost nematoda u tlu.The aim of this study was to determine the influence of liquid chicken manure preparation on the biological diversity of the nematode as an indicator of soil health. The field trial was conducted two years in two treatments and three sampling per year. One parcel was treated with liquid chicken manure preparation (Ekobooster and Ekovital), while the other was controlled. In the first year of testing, wheat was shredded. The results show that genus biodiversity was significantly more numerous in treatment with (Ekobooster and Ekovital). Indices of disturbances (MI, MI [2-5], PPI / MI) show statistically significant differences over two years and point to the stability of ecosystems, reduction of phytoparasitic nematodes and a host of useful nematodes in treatment. It can be concluded that the use of the preparation based on liquid chicken manure significantly increases the bio-diversity of the nematode in the soil
