Studies on certain aspects of root surface fungi IV. Succession of fungi on Pennisetum typhoides in fertilized soils

Abstract

The mycoflora and its succession on decomposing roots of P. typhoides of plots fertilized with urea, ammonium sulphate, superphosphate, organic manure, fresh leaves and twigs of Ipomoea fistulosa and irrigated has been investigated. Fungi were higher on fertilized plots, both a root surface and away from it (the control). Highest and lowest population were recorded soils fertilized with organic manure and I. fistulosa. The amino acids and sugars, cellulose, hemicellulose and lignin components of the roots from fertilized and control plots has been estimated and a correlation between mycoflora succession and the above components has been established.
