Nitrogen Estimation for Grapevine (In Veraison) Using RGB Color Image Processing.


Invasive methods such as petiole/leaf analysis are laborious and time consuming. The methods were proposed by many researchers that obtain nutrient analysis by non invasive method. This paper proposes RGB color image processing based method for nitrogen estimation in veraison. The Green index Igreen shows strong positive correlation with coefficient of 0.90 and other index Ikaw shows strong negative correlation with coefficient factor -0.88. The correlation between chlorophyll and nitrogen showed positive correlation. The method proposed on the basis of Igreen index is cost effective and less time consuming.
