Nitrogen fertilizer amount has minimal effect on rhizosphere bacterial diversity during different growth stages of peanut.

ABSTRACT: The impact of short-term nitrogen fertilizer input on the structure and diversity of peanut rhizosphere microbiota (RM) at different growth stages (GSs) was explored in the southern paddy soil planting environment. Three levels of nitrogen were applied in the field: control (LN, 0 kg/hm²), medium nitrogen (MN, 55.68 kg/hm²), and high nitrogen (HN, 111.36 kg/hm²). The rhizosphere soil was collected during four GSs for high-throughput sequencing and chemical properties analysis. The effect of nitrogen fertilizer application on peanut RM was minimal and was obvious only at the seedling stage. In the four peanut GSs, a significant increase in relative abundance was observed for only one operational taxonomic unit (OTU) of Nitrospira under HN conditions a
