Summary

The effect of foliar sprays of urea on the Aspergilli of the rhizosphere ofTriticum vulgare L was studied in detail. In all 16 species ofAspergillus were isolated from the rhizosphere region of wheat. The urea-treated plants (five sprayings) registered largest number ofAspergillus species. Out of 16 species the percentage occurrence of the following species,A. nidulans, A. rugulosus, A. sydowi A. fumigatus, A. niger andA. flavus, increased with the sprayings of urea. There was a general increase in the concentration of amino acids in urea-treated plants. But fourfold increase in the concentration was noted in the case of γ-aminobutyric acid and glutamine. In contrast to this the concentration of organic acids decreased as the sprayings increased.
