How to use LCC in Paddy?

Warning: The colors depicted in the image may vary from the actual colours.
We highly recommend not using these images for any comparisons or trials.

1. At 14 days after transplanting (DAT) or 21 days after direct wet seeding (DAS), randomly select 10 healthy plants in your field where plant distribution is uniform.

2. Compare the topmost, fully expanded, and healthy leaf of each of the 10 plants with the LCC. Place the middle part of the leaf on top of the LCC’s color strips for comparison. Do not detach the leaf. Take readings at same time of the day (8-10 AM). Do not expose the LCC to direct sunlight during readings. The same person should take the first up to the last LCC reading.

3. If six (6) or more of the 10 leaves have readings below the critical LCC value, apply N as given below.

  • For wet season (Kharif) non-basmati rice, use LCC critical value 4, and apply 28 kg N/ha or 1.25 bag urea per hectare.
  • For wet season (Kharif) basmati rice, use LCC critical value 3, and apply 23 kg N/ha or 1 bag urea per hectare.
  • For direct-seeded rice, apply 23 kg N/ha as basal, then use LCC critical value 3, and apply 23 kg N/ha or 1 bag urea per hectare.
  • For Boro rice, apply 23 kg N/ha as basal, then use LCC critical value 4 and apply 35 kg N/ha or 1.5 bags of urea per hectare.

4. Repeat LCC readings every 7 days for 110-130-day rice crops and every 10 days for more than 130-day crops until first heading. Different sets of 10 leaves can be used for each weekly or 10-day reading.

5. If basal fertilizer with N (DAP or NPK compound) is applied 0-14 DAT or 0-14 DAS, the first LCC reading is done at 21-25 DAT or 28-30 DAS instead of 14 DAT or 21 DAS.

PAU-LCC Recommendation in transplanted basmati rice

• No basal urea should be applied at the time of transplanting of basmati rice.
• Start matching colour of the topmost fully exposed intact leaf of the randomly selected ten basmati rice plants with the LCC at 7 day interval after 21 days of transplanting.
• Every time match colour of the ten intact leaves with LCC shade 3.5 (for Basmati 386 and Basmati 370) and LCC shade 4 (for Punjab Basmati 3, PUSA Punjab Basmati 1509, Punjab Basmati 2, PUSA Basmati 1121).
• Whenever the greenness of 6 or more out of 10 leaves is lighter than the specified LCC shades, apply 9 kg urea per acre.
• No urea should be applied if colour of 6 or more out of 10 leaves is equal to or darker than specified LCC shades.
• Discontinue urea application after initiation of flowering.


Note: 

1. The PAU-LCC is highly beneficial for optimum fertilizer nitrogen applications in fields amended with organic manures.
2. Select only representative plants and match the colour of the intact leaves with the LCC under the shade of your body.
3. The plants selected for matching colour should be normal and free from disease/insect incidence, water logging/stress and other nutrient deficiencies.
4. Urea shall not be applied in standing water in rice and next irrigation shall be given 2 days after application of urea.

How to use LCC in Wheat?

Warning: The colors depicted in the image may vary from the actual colours.
We highly recommend not using these images for any comparisons or trials.

Use organic manures for improving soil productivity. Adopt PAU-LCC for need-based application of fertilizer nitrogen and ensure soil test for application of fertilizers other than nitrogen.


PAU LCC Recommendation in wheat

• At sowing, drill 55 kg DAP per acre in medium fertility soils. No urea is required at sowing.
• At first irrigation, apply 40 kg urea per acre for timely sown and 25 kg urea per acre for late sown (after mid-December) wheat.
• Before 2nd irrigation (about 50-55 days after sowing), match colour of the topmost fully exposed intact leaf of ten representative plants with LCC.
• At second irrigation, if leaf greenness of 6 or more leaves out of 10 leaves is more than LCC shade 5.0 apply 15 kg urea per acre, between LCC shade 4.5 to 5 apply 30 kg urea per acre, between LCC shade 4.0 to 4.5 apply 40 kg urea per acre and less than LCC shade 4 apply 55 kg urea per acre, respectively.


Note: 

1. Always match the colour of the intact leaf with the LCC under the shade of your body.
2. The leaves selected for matching colour should be normal and free from disease/insect incidence, water logging/stress and other nutrient deficiencies.
3. In wheat, if second irrigation is delayed due to rains the fertilizer nitrogen should be applied at 50-55 days after sowing after matching colour with the LCC.

How to use the LCC in Baby Corn?

Warning: The colors depicted in the image may vary from the actual colours.
We highly recommend not using these images for any comparisons or trials.

The sowing of Baby Corn crop can be done at any time during April to the first week of August. It is possible to have two or more crops from the same piece of land as this crop completes in less than 60 days. Staggered sowing should be done to maintain the supply as per demand. Sow the crop having row to row spacing of 30 cm and plant to plant of 20 cm using 20 kg seed per acre.


PAU-LCC Recommendation in Baby Corn

Apply 24 kg N (52 kg urea) per acre in two equal splits i.e., at sowing and knee-high stage. Use PAU-Leaf Colour Chart (PAU-LCC) for need-based urea application as below:

• Apply basal dose of 18 kg urea per acre at the time of sowing.
• Match colour of the youngest leaf (with fully exposed collar) from the 10 randomly selected Baby Corn plants with PAU-LCC shade 5, starting from 21 days after sowing for spring and summer season while 28 days after sowing for winter season up to initiation of silking stage at 10-day interval.
• Whenever the greenness of 6 or more out of 10 leaves is less than LCC shade 5, apply 18 kg urea per acre.
• No urea should be applied, if leaf colour is equal to or darker than LCC shade 5.
• Use of LCC should be discontinued after initiation of silking and no more urea should be applied.


Note: 

1. Always match colour of the leaf with PAU-LCC under shade of the body.
2. The leaves selected for measuring leaf greenness should be free of insect-pest or disease incidence.
3. There should not be water stress to the crop, and nutrients other than nitrogen should be supplied as per recommendations.
