Estimation of nitrate nitrogen content in cotton petioles under drip irrigation based on wavelet neural network approach using spectral indices

Abstract Background Estimation of nitrate nitrogen (NO3 −–N) content in petioles is one of the key approaches for monitoring nitrogen (N) nutrition in crops. Rapid, non-destructive, and accurate evaluation of NO3 −–N contents in cotton petioles under drip irrigation is of great significance. Methods...
