This editorial observes 200 volumes of Agricultural Systems. Volume 1, dated January 1976, began with an article by the inaugural editor, C.R.W. Spedding (1976), that laid the foundations for this journal. We echo that first editorial with this contribution to begin Volume 201 and review some aspects of the history of the journal. To celebrate those 200 volumes, we have prepared a Collection of the highly-cited papers published over the last 46 years in those volumes. Here we present brief summary information about the journal, compare themes common to the opening editorial and the highly-cited papers, and conclude with an intent to review the aims and scope of the journal over the next year or so.

这篇社论观察了 200 卷农业系统。第 1 卷，日期为 1976 年 1 月，以首任编辑 CRW Spedding (1976) 的一篇文章开头，该文章为本刊的创立奠定了基础。我们在第 201 卷开始时以这篇文章回应了第一篇社论，并回顾了该期刊历史的某些方面。为了庆祝这 200 卷，我们准备了一个集合，收集过去 46 年来在这些卷中发表的高被引论文。在这里，我们提供有关该期刊的简短摘要信息，比较开篇社论和高被引论文的共同主题，并在结束时回顾该期刊在未来一年左右的目标和范围。
