Assessment of colour indices derived from conventional digital camera for determining nitrogen status in rice plants

Concerns over the use of nitrogen have increased due to the increase in fertilizer costs and environmental pollution from excess nitrogen applications in farms and paddy fields. This study assessed colour indices derived from images captured by two different kinds of conventional digital cameras (na...
