Mean Maize Yield (T/Ha/Season) Medium Season Hybrid Plant Date: 15 December

This data set contains Maize, Zea mays L. in South Africa and is the country`s most important field and grain crop. Objectives of the study was to simulate maize yields, and their inter-annual, at a spatial resolution of Quaternary Catchments for 12 different combinations of three plant dates, viz. 15 October, 15 November and 15 December. This was done to evaluate which hybrid lengths and plant dates give the highest yields irrespective of plant dates and hybrid lengths respectively and also which hybrid lengths and plant dates give the lowest coefficients of variation (%) irrespective of plant dates and hybrid lengths respectively.

本数据集涵盖南非境内的玉米（Zea mays L.），该作物是南非最重要的大田与粮食作物。本研究以第四纪集水区（Quaternary Catchments）为空间分辨率单元，针对由3种播种日期（即10月15日、11月15日与12月15日）构成的12种不同组合，模拟玉米产量及其年际变化。本研究旨在开展两项评估：其一，分别筛选出不考虑播种日期影响时可实现最高产量的杂交品种生育期，以及不考虑杂交品种生育期影响时可实现最高产量的播种日期；其二，分别筛选出不考虑播种日期影响时可获得最低变异系数（%）的组合，以及不考虑杂交品种生育期影响时可获得最低变异系数（%）的组合。
