The study aims to analyze the effects of nitrogen fertilizer rates and wheat varieties on grain yield.
Examined twenty-one winter wheat varieties over one growing season.
Applied nitrogen in rates of 120, 150, and 170 kg N ha-1.
Measured yield contributions from variety, fertilizer rate, and their interaction.
Rubisko variety achieved the highest yield of 7067 kg ha-1 at 120 kg ha-1 nitric N rate.
Wheat variety contributed 61% to yield, while fertilizer rate contributed 2.4%.
Increased nitrogen dose did not linearly correlate with increased wheat grain yield.
