摘要

厄瓜多尔安第斯地区正受到气候变化的影响,需要改进农业最佳管理做法,以提高产量和粮食安全。我们进行了一项研究,比较了不同的施氮量,以确定该地区马铃薯(Solanum tuberosum L.)系统的最佳施氮量。我们研究了N的五种施用率:0、100、200、300和400 kg N ha− 1.试验结果表明,施氮量为300 kg N ha-1时 1与不施用N相比,生产力和净收入分别提高了87%和146%。我们将这些改进的做法转移给农民,所有农场都提高了产量和净经济回报。这些农民的平均产量和净经济回报分别增长了50%和64%。需要进行更多的氮利用效率研究,以继续提高安第斯地区农民的产量和经济回报。

Nitrogen Management Can Increase Potato Yields and Food Security for Climate Change Adaptation in the Andean Region

The Andean region of Ecuador is being impacted by climate change, and improved best management practices for agriculture are needed to increase yields and food security. We conducted a study comparing different nitrogen (N) rates to determine the optimum N application rate for potato (Solanum tuberosum L.) systems in this region. We examined five application rates of N: 0, 100, 200, 300, and 400 kg N ha− 1. The results suggest that an N application rate of 300 kg N ha− 1 increased productivity and net income by 87% and 146%, respectively, compared to no application of N. We transferred these improved practices to farmers, and all farms increased their yields and net economic returns. The average yields and net economic returns for these farmers increased by 50% and 64%, respectively. Additional N use efficiency (NUE) studies are needed to continue increasing yields and economic returns for farmers in the Andean region.
