  • Extension and Farmers
  • Researchers and Scientists
  • Educators, Trainers and Students

The tools will help users to develop location specific nutrient management guidelines for rice.


Nutrient Decision Support System (NuDSS) Software for Irrigated Rice

IRRI NuDSS - Nutrient Decision Support System for Rice
The Nutrient Decision Support System (NuDSS) for irrigated rice is part of an initiative by the Irrigated Rice Research Consortium to provide decision support on site-specific nutrient management (SSNM) in the irrigated lowlands. It is a software program used to estimate the nutrient requirements for realistic target yields in irrigated rice, select the adequate and least costly combination of quality fertilizer sources to match the nutrient requirement, decide on fertilizer split applications, and estimate the profit gained from improved nutrient and crop management programs.

Nutrient Expert for Hybrid Maize Software

Nutrient Expert for Hybrid Maize Software
The Nutrient Expert for Hybrid Maize is a new, computer-based decision support tool developed by IPNI, with financial support from IPI. The software assists local experts quickly formulate fertilizer guidelines for tropical hybrid maize based on the principles of site-specific nutrient management (SSNM).
