  • Time of application is decided by LCC score.

  • Take observations from 14 DAT in transplanted rice or 21 days after sowing in direct seeded rice.

  • Repeat the observations  at weekly intervals up to heading.

  • Observe the leaf colour in the fully opened third leaf from the top as index leaf.

  • Match the leaf color with the colours in the chart during morning hours (8-10 am).

  • Take observation in 10 places.

  • LCC critical value is 3.0 in low N response cultivars like White Ponni and 4.0 in other cultivars and hybrids

  • When 6/10 observations show less than the critical colour value, N can be applied @ 35kg N/ha in dry season and 30kg N/ha in wet season per application per ha.
