Interaction between Microbial Flora and Acarine Fauna of Jatropha Plantation in Tripura

Dr. Soma Datta

Abstract: Seasonal population dynamics of acarine fauna and fungal flora was studied on soil of Jatropha plantation during February 2018 to January 2019. Study indicated highest acarine fauna (7.650.11nos. /m2x1002) during September, 2018 and lowest was recorded (1.00.2nos. /m2x1002) during March, 2018. On the other hand, peak fungal population was recorded in September (13.50.72 fungal colony/gm. soil in 10-3 dilution) and the less nos. was recorded during February (4.60.12 Fungal colony/ gm. soil in 10-3 dilution). Also out of 11 different genera, 13 species of acarine fauna, Archegozetes sp. was found to be more dominant (17.55 %) followed by Lamellobates sp. (13.76 %). Whereas, out of 10 genera of fungal flora, the dominant species was Trichoderma harzianum (21.87 %) followed by Cladosporium cladosporidae (11.46 %). Multiple regression analysis revealed significant influence by all the abiotic factors (F=15.96: p<0.001). But acarine fauna showed positively correlated with the fungal flora (r=0.809; p<0.001).
