Optimum seeding rate for biomass sorghum in response to harvesting and planting dates in the Mid-Atlantic regions

This dataset includes measurements from a field study evaluating biomass sorghum growth and performance at two sites over three years. The dataset contains dry matter yield (Mg ha⁻¹), plant height (cm), stem diameter (mm), disease severity (%), and lodging severity (%). It also includes biomass yields harvested at different times within the growing season. These data were used in the manuscript to assess the impact of seeding rate on biomass sorghum performance in the Mid-Atlantic region in response to planting date and harvest time., , # Optimum seeding rate for biomass sorghum in response to harvesting and planting dates in the Mid-Atlantic regions

本数据集涵盖一项田间研究的实测数据，该研究于两个试验地点、三年周期内评估了生物质高粱（biomass sorghum）的生长状况与生产表现。数据集包含干物质产量（Mg/ha）、株高（cm）、茎粗（mm）、病害严重度（%）及倒伏严重度（%）等指标，同时收录了生长季内不同收获时间下的生物质产量。本数据集用于支撑一篇学术论文的分析，以评估大西洋中部地区播种密度对生物质高粱表现的影响，该分析同时考量了播种期与收获期的交互效应。
