Leaf Colour Chart

Product Description

These charts are Nitrogen parameters which provide guidance to the farmers regarding improved Nitrogen (N) management. Nitrogen is applied by the farmers in rice plants at different growth stages, but the amount of N to be applied and the time of applications vary substantially. LCC helps to synchronize N application with the real time and quantity demand of the rice crop.

• Helps to prevent under or over usage of N in rice plants
• Helps to reduce pest attacks since presence of excessive nitrogen attracts pests in plants.
• Helps to increase yield.
