Yield and simulated yield data for sunflower, peanut and soybean from three sites at Punda Maria, Ofcolaco and Syferkuil, Limpopo Province, South Africa

The data contains yield data from farm experiments and DSSAT simulated future yield for sunflower, peanut and soybean. The field experiments were conducted during the summer growing seasons of 2016/2017 and 2017/2018, across three sites (Punda Maria, Ofcolaco and Syferkuil) in the Limpopo province, South Africa. The province has three distinct climatic regions that can be classified as (i) lowveld (arid and semi-arid) regions, (ii) middle veld and highveld (semi-arid) region, and (iii) the escarpment region which has a sub-humid climate receiving 700 mm rainfall per annum. Crop production highly depends on the summer rainfalls received mostly from October to March. Most smallholder farming is rainfed. In the first season, experiments were established at the Syferkuil experimental farm (23°50’38” S and 29°41’13” E) and at a farmer’s field at Ofcolaco (24°06’41” S and 30°23’26” E). In addition to these field trials, a farmer’s field at Punda Maria (22°49’18” S and 30° 54 ’37” E) was included in the second season following the granting of an ethical clearance from the University of Limpopo ethics committee and by the signing of a consent form by the farmers.

本数据集涵盖农田试验产量数据，以及向日葵、花生与大豆的DSSAT模型（DSSAT）未来模拟产量数据。田间试验于2016/2017及2017/2018年夏季作物生育期内开展，试验覆盖南非林波波省（Limpopo）的三个站点：蓬达玛丽亚（Punda Maria）、奥夫科拉科（Ofcolaco）与赛弗奎尔（Syferkuil）。该省存在三类差异化显著的气候分区，具体划分为：(i) 低草原（lowveld）——干旱与半干旱区域；(ii) 中草原与高草原（middle veld、highveld）——半干旱区域；(iii) 陡崖带（escarpment）——半湿润气候区，年降雨量达700毫米。区域作物生产高度依赖夏季降雨，降雨时段多集中于10月至次年3月，绝大多数小农经营均采用雨养模式。首个试验季中，试验分别设于赛弗奎尔试验农场（23°50’38” S，29°41’13” E）与奥夫科拉科的一处农户农田（24°06’41” S，30°23’26” E）。除上述田间试验外，在获得林波波大学伦理委员会的伦理审批且农户签署知情同意书后，蓬达玛丽亚的一处农户农田（22°49’18” S，30°54’37” E）被纳入第二个试验季。
