Abstract

Applying nitrogen to a rice crop at panicle initiation to increase yield is efficient and reliable. The NIR (Near Infra-red Reflectance) tissue test has been the industry standard for measuring crop growth and nitrogen at panicle initiation since the mid 1980s. However, many growers and agronomists do not take advantage of this technology and instead rely on estimating the rice crop’s nitrogen requirements. One of the main reasons growers do not use the test is difficulty in sampling the rice crop in the water.
