Thirteen species of fleshy fungi were identified from two agricultural fields during the 1989 and 1990 growing seasons at the Rural Development Center (RDC) and Horticulture Farm, Coastal Plain Experiment Station, Tifton, Georgia. The three most common fungi wereCoprinus plicatilis, Cyathus olla, andPanaeolina foenisecii. At the former site, residue management practices were established for evaluating crop production and at the Horticulture Farm different crops were grown with conservation tillage employing a Low Input Sustainable Vegetable Production system. Tillage treatments at the RDC were no-till, row-till, ridge-plant, and moldboard-plowing. Residue management of triticale included burning or cutting the stubble at a height of 20 or 60 cm at harvest. At the Horticulture Farm, seven winter cover crops were compared to a fallow control. No significant differences were shown between observations of fungal species and individual treatments at the Horticulture Farm during 1989 and 1990. However, there were treatment differences for observed fungi at the RDC farm on specific dates for both years. Furthermore, no individual treatment(s) during the investigation increased observation rates of specific fungal species. Non-burned debris treatments showed consistently higher populations and diversity of fungi than burn debris plots. |
