Study of the relationship between the chiorophyll and the nitrogen content of oilseed rapes
In order to fined the relationship between the SPAD value and the nitrogen content of oilseed rapes, a Minolta SPAD-502 Meter was used for on-farm measurement of the N content, and then the Kjeldahl method has been used for measuring the nitrogen content of these oilseed rapes. The results of these...

| Summary: | In order to fined the relationship between the SPAD value and the nitrogen content of oilseed rapes, a Minolta SPAD-502 Meter was used for on-farm measurement of the N content, and then the Kjeldahl method has been used for measuring the nitrogen content of these oilseed rapes. The results of these two methods have been fitted, as a result, the correlation coefficient is 0.863, a new method for quickly measuring the nitrogen content of oilseed rapes is offered. |
