RESPONSE OF HULLED AND NAKED OAT TO FOLIAR FERTILIZATION
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2016, Vol 15, Issue 2
Abstract
In agricultural practice, foliar fertilizers are applied in foliar additional plant feeding. Foliar additional feeding provides plants with nutrients in small doses which are immediately activated and uptaken by the leaves. The work presents the results of a strict field experiment set in 2009-2011 at the Didactic-Experimental Station of the University of Rzeszów in Krasne near Rzeszów. Response of naked (cultivar Cacko) and hulled (cultivar Bingo) oats grown on medium soil, good wheat complex to foliar fertilization with Bio-algeen S 90, Basfoliar 12-4-6+S, and Basfoliar 36 Extra was studied. Grain yield and chemical composition were determined, as well as canopy architecture. On the basis of the conducted research, it was demonstrated that foliar fertilizers caused an increase in oat grain yield. The highest yield was obtained after the application of Basfoliar 36 Extra and Basfoliar 12-4-6+S. Also positive effect of foliar additional feeding was found on the formation of such yield components as mass of 1000 grains and the mass and number of grains per panicle. It was demonstrated that the applied foliar fertilizers determined the decrease in protein content and increased the fat content in the grain. The most intense response occurred after the application of Bio-algeen S 90. Foliar fertilizers also diversified canopy architecture. After their application, an increase in the leaf area index (LAI) and a decrease in the mean tip angle (MTA) were demonstrated. The highest increase in LAI and decrease in MTA in both oat cultivars was found after the application of Basfoliar 36 Extra.
