Optimising Plant Establishment 2020 Hart Seeder Comparison Data

Data from a comparison of three commercial seeders on a wheat tillage trial at Hart, SA. Crop establishment and interplant distance were measured on each of the three seeders: a disc seeder, no-till seeder and strategic seeding.Files:Seeder comparison wheat.xlsxExperiment setup:The Hart tillage experiment was managed by the Hart Field-Site Group, and set up as a split plot design with the seeder as the whole plot treatment (disc seeder, no-till seeder, and strategic seeder), and nutrition as a subplot treatment (Medium vs High), with 3 replicates and 18 plots total.Variables recorded:plant establishment (plants/m2), interplant distance (cm), seedling depth (mm)Data collection and assessment:Measurements were made on individual types and row from the Hart tillage trial, with plant establishment and interplant distance measured on individual rows and linked to the sowing tyne by row and rank. Seedling depth data was recorded for the medium-nutrition plots in replicate 1 only, averaged across 5 measurements.

本数据集源于对哈特，南澳大利亚地区三种商业化播种机在小麦耕作试验中的比较研究。对三种播种机（圆盘式播种机、免耕播种机和战略播种机）分别测量了作物定植和株间距离。文件：Seeder comparison wheat.xlsx实验设置：哈特耕作试验由哈特现场试验组管理，采用裂区设计，播种机作为整个试验区的处理（圆盘式播种机、免耕播种机和战略播种机），营养作为亚区处理（中肥与高肥），共计3个重复和18个小区。记录的变量：植株定植（株/m²）、株间距离（厘米）、幼苗深度（毫米）。数据收集与评估：对哈特耕作试验的单个类型和行进行了测量，植株定植和株间距离是在单行中测量的，并与播种行和等级相关联。仅在重复1的中肥地块中记录了幼苗深度数据，并平均了5次测量的结果。
