Abstract:
The ecology of Arbuscular Mycorrhizal Fungi (AMF) in mono-cropping and low-input ideal agroforestry cropping systems of Avena sativa has been studied. Soil chemical heterogeneity, seasonality and nature of cropping system showed significant attributes on AMF. AMF percentage in roots and spore populations in soil were elevated in dry season compared to wet season. With respect to cropping regimes, mono-cropping systems exhibited highest root infection whereas the agroforestry systems possessed highest AM fungal spore populations. Generally, farming systems tested here possessed significant colonization of AMF, however, overall extent of colonization and spore densities were low. While assessing the correlation between soil chemical composition and AMF, electrical conductivity, organic carbon content, available potassium and saturation percentage showed a negative correlation. However, pH showed a positive correlation and available phosphorus content showed no correlation with AMF. Present study was aimed to view the importance of agroforestry in modern agriculture and normal agricultural system and the benefits associated with AM fungi.
