The Influence of the Quantity and Form of Nitrogen on Productivity of Winter Wheat

Abstract

This paper examined the influence of the quantity and form of nitrogen on the important parameters of productivity of winter wheat. Field microexperiments were conducted in agroecological conditions of Central Serbia and loam soil type (vertisol). The results showed significant differences in the spike length, number of spikelets, grain yield and hectoliter weight between examined quantities of nitrogen. On the contrary, a form of nitrogen had not a significant effect on the observed parameters of productivity of wheat.

U ovom radu je ispitivan uticaj količine i oblika azota na važnije parametre produktivnosti ozime pšenice. Poljski mikroogled je postavljen u agroekološkim uslovima centralne Srbije i na zemljištu tipa smonica (vertisol). Dobijeni rezultati su pokazali značajne razlike u dužini klasa, broju klasića, prinosu zrna i hektolitarskoj masi između ispitivanih količina azota. Suprotno tome, oblik azota nije ispoljio značajan uticaj na posmatrane parametre produktivnosti pšenice.
