Chlorophyll meter- and leaf color chart-based nitrogen management for rice and wheat in northwestern India
Overapplication of N in cereal crops leads to low N recovery efficiency and risk of NO3 pollution of ground water. The chlorophyll meter, also known as SPAD meter, is a simple, portable diagnostic tool for identifying crop N status. We used it to test need‐based N management approaches for rice (Ory...
