Responses of diversity, productivity, and stability to the Nitrogen input in a tropical grassland

Present data has been collected from an experimental tropical grassland located in Banars Hindu University, India using 72 1×1m plots with 6 N-input levels and with 12 replicates. The experiment was established in 2013. For three years, different doses of urea as a source of N were applied to the plots. Data on individuals and biomass of each species were recorded and statistically analysed. This study reports the effects of different levels of N application on species composition, and the diversity, Productivity, Temporal stability and their relationships.

本数据集采集自印度巴纳拉斯印度教大学（Banars Hindu University）的一处热带草原实验样地，实验共设置72个1×1平方米的样方，涵盖6个氮素输入（N-input）梯度，每个梯度设置12次生物学重复。该实验于2013年启动，后续三年间，研究人员向各样方施加不同剂量的尿素作为氮素来源。研究人员记录了各物种的个体数量与生物量（biomass）数据，并进行了统计分析。本研究阐明了不同施氮水平对植物物种组成（species composition）、多样性（diversity）、生产力（Productivity）、时间稳定性（Temporal stability）及其相互关系的影响。
