Better information from improved NIR tissue test
The NIR Tissue Test is a free service for rice growers and agronomists, allowing them to make better nitrogen topdressing decisions for their rice crops.
- Good rice nitrogen management leads to increased grain yield, water use efficiency and proﬁtability.
- The NIR Tissue Test allows the accurate determination of the rice crop’s nitrogen requirements at panicle initiation (PI) based on economic return.
- Recent updates to the NIR Tissue Test program have improved its accuracy for current rice varieties.
- The PI predictor is a useful tool for helping to determine approximately when PI should occur in a crop.
