Effect of nitrogen mineral nutrition in extreme climatic conditions on sugar beet production

Abstract

Continuous advancements in plant breeding and the development of new hybrid varieties are occurring alongside the challenges posed by climate change. Consequently, there is an ongoing need to reassess agricultural practices. Fertilisation, particularly with nitrogen, plays an important part in plant production. Nitrogen is a critical element required in significant quantities for optimal crop growth, influencing the yield of various crops. However, it's important to acknowledge that nitrogen is a dynamic element, and substantial nitrogen reserves cannot be retained within the soil. Given the distinct requirements of sugar beet cultivation, where nitrogen not only impacts root yield but also profoundly influences root quality, it becomes important to improve fertilisation management. Therefore in our study we focused on assessing the effects of five different nitrogen fertiliser levels (40, 80, 120, 160, and 200 kg N/ha) on root yield and quality of two commercial sugar beet hybrids.
