The Number and Significance of Actinomycetes in the Soil in the Stage of Physiological Corn (Zea Mays L.) Kernel Maturity

Abstract

In this work, it is determined the number of actinomycetes, a very diverse order of microorganisms, which take part in the transformation of the soil organic matter depending on the soil type, the quantity of applied N and the way of the soil treating. The stage of physiological corn kernel maturity shows the higher number of actinomycetes in "cernozem" under the sown maize as well as a stimulating effect of nitrogen.

U ovom radu, određena je brojnost aktinomiceta, veoma raznovrsne grupe mikroorganizama, koja učestvuje u transformaciji zemljišne organske materije, u zavisnosti od tipa zemljišta, količine primenjenog azotnog (N) đubriva i načina obrade zemljišta. U fazi fiziološke zrelosti zrna kukuruza, utvrđena je veća brojnost aktinomiceta u černozemu, pod usevom kukuruza, kao i stimulativni efekat azota.
