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.

• LCC helps to decide whether the application of N needs to be adjusted up or down based on the leaf colour throughout a plant’s lifetime
• 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.

• 4 panel LCC that can be used for all high yielding rice varieties.
• LCC from left to right – the given colors are numbered as 2,3,4,5. ‘2’ denotes less N in plant. ‘3’ denotes presence of correct amount of N in plant where as ‘4’ and ‘5’ denote excessive and over-excessive presence of N respectively.
• Colors of the chart to be matched with the first unfolded leaf of a plant every 18 to 20 days in case of long duration crops and every 15 to 18 days in case of short duration crops. The person should stand with his back towards the sun while matching the colors.
