Important tips for obtaining high yields of rice

Considered the following points for obtaining high yields:

Get pure seed of new high yielding varieties recommended for the area.
Treat the seed with suitable fungicide/ bio-organics or as per need.
Formulate timely field operations such as sowing or transplanting.

  • Prepare healthy seedlings by adopting recommended practices.
  • Adopt the stale bed technique in irrigated ecology for better control of weeds.
  • Maintain plant population 45-50 hills per square meter area.
  • Transplant seedling at a distance of 20 x 10 cm or 15 x 15 cm at a depth of 2-3 cm.
  • If transplanting is delayed increase the seedling number per hill or closer the planting. Use healthy young seedlings of 20 – 21 days.
  • Transplant 2-3 young seedlings per hill of high yielding varieties and 1-2 for hybrids.
  • Apply plant nutrients in correct proportion and in balance amount.
  • The recommended doses of NPK i.e.120 kg N, 60 kg P2O5 and 60 kg K2O per hectare.
  • Apply all P and K fertilizer and half dose of N at last puddling and then remaining N is to be applied in 2-3 Splits. First at the time of tillering and second 5-6 days before panicle initiation. In light texture soil more splits of N are made.
  • May use crop need based N as per Leaf Color Chart (LCC).
  • Phosphorus and Potassium fertilizer should be applied after soil test.
  • Top-dress the Urea fertilizer after draining out the excess water from the field, next day again irrigate the field.
  • First remove the weeds and then top-dress the Urea.
  • Never allow forming cracks so don’t create wet and dry situations.
  • Maintain the water level 0-5 cm till heading and milk stage as it suppress the weed growth. In early crop growth keep less standing water, as it promotes tillering.
  • Khaira is common occurrence in early stage. For tackling Khaira (Zn-deficiency) disease of rice, apply 0.5% ZnSO4 solution twice at10 and 20 days after transplanting or Dip the seedling roots of rice in 2 % ZnO solution.
  • Apply 0.5 % FeSo4 solution if plant shows yellowing of new leaves.
  • Add organic manure after the harvest of Rabi crops in April-May. Well incorporate the Green manure in the soil.
  • In addition to organic manures, use the bio-fertilizers (Azolla, Cynobecteria, Azospirilum, Azotobacto, Phosphorus solubilizing bacteria etc.). These adds / solubilizes nutrients ranging from 25- 30 kg per ha.
  • Do timely harvesting, threshing, drying and storage(less than 14 % moisture).
Frequently asked questions:

Question1: How seeds of rice are treated?
Answer: seeds are treated with suitable fungicides, like Bavistin or Carbendazim or Thiram (2.5 to3.0 g/ kg of seed)

Question 2: Which hybrid varieties are suitable for Sikkim?
Answer: Pant Dhan -10, VL-62, Sugandha-II etc will be suitable.

Question 3: I have grown paddy but it got some disease problem. The growth tend to cease, stunted, poor tillering and brown rusty spots on leaf blade and these spots are slowly enlarging. Please tell me what I should do for this?
Answer: These are the symptoms of Kharia, a Zinc deficiency disorder. For this apply 0.5 % ZnSO4 solution twice at an interval of 10-15 days. For making solution, take 15 liter water, put 75g ZnSO4 and add 200 g urea in it.

Question 4: I have very good crop of paddy at my village but now it showing discoloration in the leaf margins, color of plants turning dull ashy, what it may be and how it can be corrected?
Answer: As per symptoms, it may be bacterial leaf blight (BLB) disease, for the control of BLB, first drain out water from the filed and stop urea top–dressing. Apply Streptocyclene 15g with 500g Copper Oxychloride (Blitox /Phytolan) dissolving in 1000 liter of water. Two sprays of this solution be made each an interval of 10 days.
