Effect of nitrogen mineral nutrition on yield and some technological traits of sugar beet root in 2017

Abstract

Constant progress in plant breeding, the development of new hybrids and varieties, accompanied by climate change requires continuous review of growing technology. The most important part of plant production is fertilization, particularly with nitrogen. Nitrogen is required in great quantities for growing plants and it affects the yield of many crops. However this is very dynamic element and large nitrogen reserves cannot be stored in the soil. Considering the specificity of sugar beet production, where nitrogen, in addition to its impact on root yield, significantly affects the quality of the root, it is necessary to constantly review fertilization protocols. Effects of four levels of nitrogen fertilizers (40, 80, 120 and 160 kg N ha-1) on root yield and quality of commercial sugar beet hybrids were examined in the field trials during the growing season 2017. Nitrogen fertilizers were applied before the sowing. Field trial was organised by Randomised Complete Block Design (RCBD) with four replications.
