Impact of nitrogen topdressing on the quantity and quality of yield of wheat varieties
Keywords:
N topdressing, wheat, grain yield, protein yield, crop yearAbstract
Impacts of N topdressing applications were studied in a field experiment to determine water availability grain yield and protein formation interrelations. Five winter wheat varieties and six nitrogen application levels were applied in two crop years representing different precipitation and temperature patterns to evaluate yield, yield components and quality manifestation. The results obtained suggest, that precipitation patterns in relation with the wheat development phenophases had profound influence on the grain yield and the protein formation of wheat crop. Varietal differences were determined regarding yield, protein values in relation with plant nutrition and crop year impacts. There were no or minor differences between varieties, however plant nutrition treatments induced significant differences in both crop years.
