International Conference on Four Decades of Progress in Monitoring and Modeling of Processes in the Soil-Plant-Atmosphere System location:Naples, Italy date:19-21 June 2013
Strategies to improve cereal yield in Terai (Nepal) were developed with AquaCrop by simulating different scenarios
of irrigation and fertilizer management for three dominant soil types with 30 years historical climatic data. Farmers
yield increased from 25 to 115% depending on soil type, fertility and irrigation level. Considering the low availability of irrigation water and fertilizers, use of deficit irrigation with 1/4 of the net irrigation requirement (Inet) and fertilizer application below 50% of national recommended fertilizer dose (NRFD) was regarded as the most suitable strategy.
For fertilizer applications above 50% of NRFD, deficit irrigation with 1/3 Inet is recommended.
