We examined the main and interactive effects of nitrogen (N) and deficit irrigation (DI) on the
yield response factor (K y), water use efficiency (WUE), and irrigation water use efficiency …

Abstract Internet of Things (IoT) has played a key role in developing sustainable precision
agriculture. This study addresses water and fertilizer allocation issues derived from the IoT …

Irrigation and N fertilizer management are important factors affecting crop yield, N fertilizer
recovery efficiency, and N losses as nitrous oxide (N2O) and nitrate (NO3−). Split application …

Nitrogen (N) fertilizer recommendations based on yield goals are common and do not
consider variability in soil N supply between fields. Nitrogen transformations in soils are …

The agricultural and land policies in China are always focused on protecting its food supply
and security because of the country's large population and improved diets. The crop …

In water-scarce regions, high yield and improved water use efficiency (WUE) of crops can be
obtained if water and nitrogen (N) are properly applied. While water and N have been the …

Better water and nitrogen (N) management requires better understanding of soil water and N
balances and their effects on crop yield under various climate and soil conditions. In this …

Highlights An Irrigation Scheduling Supervisory Control and Data Acquisition (ISSCADA)
system was tested against a soil electrical conductivity (EC) based method for variable-rate …

Nitrogen (N) and water continue to be the most limiting factors for profitable maize (Zea
Mays L.) production in the western US Great Plains. Precision application of N and water …

Characterizing corn (Zea mays L.) grain yield (GY) response to N is critical for maximizing
profits, increasing N use efficiency and minimizing environmental impacts. Although a large …
