What is Leaf Colour Chart (LCC)

LCC is an intelligent, instant, easy and low-cost technique handy tool made by high quality plastic material for N diagnosis of current crop and N topdressing in crops and a simple alternative to expensive equipments like chlorophyll meter / SPAD meter (soil plant analysis development) and Green Seeker. Nitrogen being a part of chlorophyll molecules (a and b) its deficiencies are reflected in Plant Leaf Colour. Hence Colour of crop Leaves was measured to judge crop N status and its fertilization. Leaf Color Chart (LCC) is a Real-Time N management technology of IRRI & ICAR to determine the exact requirements of nitrogen fertilizer of standing crops, by checking the greenness of Plant Leaf. The color panels of the LCC are designed to indicate whether plants are hungry or over-fed by Nitrogen fertilizer. By matching the color of the Paddy, Basmati Rice, Wheat, Baby Corn, Maize, BT Cotton & Sugarcane leaf to the color on the LCC, farmers can visually assess and decide proper time and amount of N fertilizer for application. LCCs manufactured in 4 Panel, 5 panel and 6 Panel for different Crops. LCCs are supplied with a matte laminated folder with the how to use instructions and other related information for Farmers and agriculture extension officers.

Purpose of Using Leaf Color Chart (LCC)

Purpose of using LCC is to apply an adequate amount of nitrogen and avoid application of fertilizer more than required. Excessive, injudicious, blanket and untimely application of fertilizer nitrogen has become a common practice among farmers. Application of nitrogen fertilizers over and above the crop requirement does not increase yield, rather a large proportion of the applied nitrogen escapes from soil-plant systems to the atmosphere, creating pollution and climate change problems. Increased succulence, over growth and dark green colour produced due to excessive nitrogen use results in increased insect-pest incidence and the crop also become prone to lodging. The unaccounted LCC benefits of decreasing insecticides - pesticides consumption shall further reduce cost of production and facilitate the availability of quality food grains, air and water. Use of LCC helps to determine nitrogen demand of the crop and guide the right time and right amount of fertilizer nitrogen application. Leaf Colour Chart ensures only need-based optimum use of chemicals in agriculture. Chemical fertilizer, particularly urea, is being indiscriminately applied to Paddy, Basmati Rice, Wheat, Baby Corn, Maize, BT Cotton & Sugarcane in its cultivated regions. There is an urgent need to rationalize the use of urea and other nitrogenous fertilizer (organic and inorganic) in a way that these are applied as per the need of the crop by using LCC. Leaf Color Chart (LCC) improves the nitrogen use efficiency and increases the productivity levels of crops, helps to save Government's exchequer on Urea or other N fertilizer subsidies, and shall add to the income of the Farmers.


Potential Savings in Urea (N) Fertilizer by using the LCC Method in selected Asian Countries (Calculated in Rice only)

With the use of LCC in the irrigated Rice, let us assume a potential saving of 23 Kg N or 50 Kg Urea per Ha per season. The calculated annual savings of Urea are provided in the Table below for selected Asian Countries (except China). The estimated annual saving of Urea is 834,000 Tons for India if 50% of farmers use LCC in the irrigated Rice area of 22.3 million Ha.

Other countries that could save substantial amounts of Urea, when they adopt LCC are Indonesia, Vietnam, Bangladesh, Thailand and the Philippines. For the whole of Asia, except China, the potential annual saving of Urea is estimated at 1, 2, 3 and 4 million Tons, respectively, with 25, 50, 75 and 100% of farmers using LCC in irrigated Rice.


Approximate Potential savings in Urea (N) Fertilizer by using the LCC Method in India (Calculated in different Crops)


If all the farmers use Leaf Colour Chart (LCC) in Rice and other Crops in India on a consistent basis, the savings of Subsidy on Urea for the Central and State Governments and the savings on the cost of purchasing Urea for the farmers amounts to INR. 18000 Crores per year approximately. Apart from that, the unaccounted benefits of using LCC are reduced consumption of insecticides and pesticides, resulting in higher yields as well as reduced nitrate contamination in ground water and reduced emission of Nitrous Oxides into the atmosphere is priceless.

Crucial Role of Leaf Colour Chart - LCC in Greenhouse Gas Emission / Climate Change

Climate Smart Agriculture (CSA) / Climate Resilient Agriculture (CRA) Technology System

The IRRI and ICAR institutes have developed Leaf Color Chart - LCC as a diagnostic tool that guides Farmers to make need-based N fertilizer / Urea application decisions based on the leaf color of the first fully exposed top leaf. The LCC can be used for synchronizing N application with crop demand to reduce Greenhouse Gas (GHG) emission and overall climate change. Climate change has serious implications concerning the food and nutritional security of nations like India where agriculture is the backbone of the nation's economy and growing population is the biggest reason to worry. In the future, it will be even more difficult to predict occurrences of phenomena such as Droughts, Floods, Cloud Bursts etc. due to Climate Change. As the use of LCC leads to the application of optimum and precised quantity of nitrogen to Crops as and when required, there is a considerable reduction in the greenhouse gas emission from crop fields. Transforming agriculture through adoption of climate resilient practices and technologies would be inevitable to stabilize agricultural production and enhance farmer's income. Participatory demonstration of location specific and climate smart technologies is necessary for enabling farmers to cope with climatic variability and extreme weather phenomenon. Considering the urgent need to address the issue of climate change at the farm level, Leaf Colour Chart (LCC) is one of the technologies promoted by IRRI / ICAR. Leaf Colour Chart (LCC) is one of the CSA technologies which is used to determine the requirements of nitrogen fertilizer to cereal crops, especially for Paddy, Basmati Rice, Wheat, Baby Corn, Maize, BT Cotton & Sugarcane based on the greenness of the plant leaf.

Nitrogen (N) in the form of nitrate is a common pollutant in both surface and ground waters. Nitrate-N can readily leach down beyond the root zone in agricultural soils and reach the ground and surface waters. At levels exceeding the permissible limits, nitrate-N makes the ground water unfit for drinking purposes. N is readily converted to nitrate and much of the unused nitrate dissolves in rain and irrigation water, eventually leaching through the soil into underlying aquifers or surface waters. Once fertilizer N is applied to the soil as urea or ammonium, it is transformed biochemically to nitrate, which is liable to leach beyond the soil–plant system to reach water bodies. In general, 10–30% of fertilizer N applied in modern agricultural systems is lost but the fate of N in the subsurface environment depends upon several biochemical and bio‐physico‐chemical processes. Due to the complex relationship between land use activities, fertilizer N management, rainfall, irrigation management, soil N dynamics and soil features, accurate quantification of nitrate leaching to surface and ground water bodies has remained a challenging task. Several researchers have reported that application of fertilizer N, particularly at levels in excess of crop N removal rate, leads to increased losses of N to surface water bodies. It was revealed that compared to traditional N management, the knowledge-based N practices significantly reduced nitrate-N leaching and losses of N through runoff. When fertilizer N is applied at rates that match crop N demand, there are virtually no or minimal direct leaching losses of applied fertilizer-N which could be possible through Leaf Colour Chart - LCC Technology.

CGIAR-CCAFS Climate Smart Village Project on Leaf Color Chart

The Consultative Group on International Agricultural Research (CGIAR) Program on Climate Change, Agriculture and Food Security (CCAFS) introduced the model of “Climate Smart Villages (CSVs)”, in some states in India. The idea was to raise awareness among farming communities in South Asia about the Leaf Color Chart (LCC) and various technological, institutional and Policy-oriented options that have the potential to increase their climatic resilience, adaptation, agriculture productivity and income, while reducing the emissions of greenhouse gases. The villages, initially started in South Asia, are now being replicated at other CCAFS regions in East and West Africa. This important research will help Policy Makers, Farmers and others affected by climate change understand the implications of their decisions when making difficult compromises.
