Different levels of nitrogen were tested on sugar beet leaves to see how it affects chlorophyll content and photosynthesis. Results showed that higher nitrogen levels led to increased chlorophyll content and photosynthetic rate. This, in turn, positively correlated with higher beet yield and sucrose content. Transpiration rate and stomatal conductance also played a role in sucrose yield. Overall, more nitrogen resulted in better photosynthetic characteristics and higher yields in sugar beet plants.
