Leaf Colour Chart Developed By
The Leaf Color Chart (LCC) is a diagnostic tool used to determine the nitrogen level in rice plants relative to the shade of green of the plant's leaves. It is a ruler-shaped strip containing at least four panels of color, ranging from yellowish green to dark green. The leaf of the plant is compared with the color panels to determine how much nitrogen fertilizer is needed.
It was developed by. Introduction The leaf colour chart (LCC) was the first time introduced in the agricultural sector of the world by scientists of Japan. They made it for estimation of chlorophyll formation and its availability in plants, after the continuous studies, many researchers proved that it is pivotal for the measurement of nitrogen deficiency and its correction.

The leaf colour chart has six (06. About Leaf Colour Chart (LCC) Leaf Color Chart (LCC) is a Real - Time N management technology of International Rice Research Institute (IRRI) & Indian Council of Agricultural Research (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.
The LCC was developed to give a visual indication of the nitrogen status of their crop. The University of California, in collaboration with the California Rice Commission and the California Cooperative Rice Research Board, has released the UC Leaf Color Chart, version 2.0. We developed and tested a new method of digital image analysis that uses Scion Image or NIH image public domain software to quantify leaf color.

This publication provides instructions for using this software to measure the percentage green and red in leaves, colors of particular importance for the assessment of plant health. Leaf colour chart (LCC) developed from a Japanese prototype (Furuya 1987) was standardized along with the Chl meter. The LCC is made of high impact plastic and consists of six colour shades from yellowish green (No.
1) to dark green (No. 6) and the holder is gray in colour. Leaf colour chart (LCC) as a tool for field-specific management of fertilizer nitrogen (N) in rice was introduced on a commercial scale in the last decade of 20th century.
About Leaf Color Chart (LCC)
During last two decades. 1 2 3 Standardized leaf color chart (developed by UCCE* in collaboration with IRRI**) released 2003 Buresh,R.J 2002 Predicted and measured leaf N content Ndw = leaf N per unit dry weight, MT = mid tillering, PI = panicle initiation, BO = booting. INTRODUCTION Leaf colour chart (LCC) is a low cost and easy to handle diagnostic tool for real-time or crop-need-based nitrogen (N) management in rice, wheat, maize and cotton crops.
LCC used as quick and reliable intelligent tool and helps rice, wheat, maize and cotton farmers to visually assess the leaf N status and to apply the nitrogenous fertilizers for these crops at different growth. The Leaf color chart (LCC) had been jointly developed by International Rice Research Institute (IRRI) and Philippines Rice Research Institute (PhilRice) from a Japanese prototype, for the purpose of measuring the required quantity of nitrogen to be applied in Rice field and thereby to get a maximum productivity. The leaf color chart (LCC) is an innovative cost effective tool for real.
