Abstract

Aflatoxin contamination, caused by Aspergillus flavus group of fungi, is a serious threat to groundnut crop profitability and human health. The objective of this study was to know the distribution of soil population density of A. flavus and its relation with soil chemical and physical properties. The soil samples collected from different groundnut growing locations of Telangana state during rabi, 2018-19 and kharif, 2019 were analysed for A. flavus population and for soil properties (pH, exchangeable calcium content and organic carbon). Soils of Mahabubnagar district had the highest A. flavus population of 7.8×103 cfu/g and 6.4 × 103 cfu/g of soil during rabi, 2018-19 and kharif, 2019 respectively whereas the lowest A. flavus populations were observed in soils of Warangal district with 1.5×103 cfu/g and Nagarkurnool district with 2.8 ×103 cfu/g during rabi, 2018-19 and kharif, 2019, respectively. A negative correlation was observed between soil calcium content and A. flavus population count. Overall, our study found varied levels of A. flavus populations in the groundnut cropping areas of Telangana state with highest A. flavus population at Mahabubnagar
district during both seasons.
