Abstract
Native communities of arbuscular mycorrhizal fungi (AMF) and plant parasitic nematodes
(PPN) were examined in fields previously under climate-smart agriculture (CSA) and non-climate
smart (NCSA) of the East Usambara Mountains. The field were differing in soil properties and
agricultural practices. Soil samples were taken from 10 sites in each of the 30 fields. AMF spores
and PPN were isolated using wet- sieving method and the Baermann tray method, respectively. The
isolated fungal spores and PPN were morphologically identified, classified and quantified. A total
of 10 AMF and 27 PPN genus were recorded. The CSA and NCSA fields had 51% and 56% of genus
Glomus, respectively. About 73.2% and 72% of genus Rotylenchulus were recovered in CSA and
NCSA, respectively. No association was found between AMF and PPN, a significant correlation
between PPN and AMF abundance with agricultural practices was observed (p=0.001). No
significant difference was found between AMF (p=0.8) and PPN communities (p=0.6) with
agriculture practices. Correlating AMF and PPN with soil properties showed no association and
no significant difference except for PPN with total nitrogen (p=0.03). Whatever the causes of no
significant difference between the treatments,the results suort that CSA practices can facilitate
mycorrhizal colonization.. Our results showed that both agriculture practices didnot influence
AMF and PPN abundance in the soil.
