| Abstract : | In the years 2012-2014 a strict field experiment was conducted at the Faculty Experimental Station of the Rzeszów University in Krasne near Rzeszów. The goal was to specify the reaction of spring wheat to differentiated nitrogen fertilisation (80 and 120 N kg∙ha-1) and to foliar feeding (Plonvit zboża). The experiment was conducted on a brown soil originating from loess, classified in valuation class IIIa of the good wheat complex. Changing weather conditions during the experiment period influenced the yields of spring wheat. On the grounds of obtained results it was noted that the higher dose of nitrogen caused a considerable increase of leaf area index (LAI) and SPAD indicator. The average inclination angle (MTA) amounted to 49.5º and was not considerably modified. Higher nitrogen fertilisation increased the number of ears on the area unit, lodging of plants, MTZ, grain plumpness and grain yield as compared with the lower doses. Foliar feeding resulted in a considerable increase of such parameters as SPAD index, MTZ and grain yield as compared with control sample. The fertilisers applied modified the chemical composition of grain. Increased dose of nitrogen increased the amount of general albumen in grain and lowered the amount of raw fibre. Foliar feeding resulted in an increase of amount of ashes in grain as compared with control sample. |
