dc.description.abstractThe 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.en
