Dos and don'ts in rice

Posted in

Treat the seeds with Carbendazim or  Tricyclozole solution at 2 g/l of water for 1 kg of seeds. Soak the seeds in water for 10 hrs and drain excess water.

 

Dos in Rice

  • Treat the seeds with Carbendazim or Tricyclozole solution at 2 g/l of water for 1 kg of seeds. Soak the seeds in water for 10 hrs and drain excess water. This wet seed treatment gives protection to the seedlings up to 40 days from seedling disease such as blast and this method is better than dry seed treatment.
  • The field should be plough at 20-25 cm depth by mould board plough in to expose the eggs of harmful insects, pests and rhizome of weed.
  • Keep the field flooded or saturated with water for about one fortnight before transplanting because this helps in decomposition of chaff and straw of previous crops.
  • The seedling should be transplanted at optimum age (20-25 days old) and two to three seedlings per hill must be transplanted in normal condition.
  • In case of saline soils 45 days old seedlings and 5-6 seedlings per hill should be transplanted.
  • The number of seedlings per hill must be increased if the old seedlings are used.
  • In each case seedlings should be transplanted at 2-3 cm depth.
  • In rice nitrogen should be given by application of Urea, Ammonium sulphate, and Ammonium chloride or NPK complex fertilizer containing no nitrate.
  • In acid soils, rock phosphate should be used as phosphorus source.
  • In zinc deficient soils 20-25 kg of zinc sulphate per hectare should be applied at time of last puddling.
  • Weed should be removed once at 20 days after transplanting (before first top dressing) and second time at 50-60 days after transplanting (before second top dressing).
  • A number of herbicides such as Stamp F-34, Machete, TOC and Basaline have been found effective in controlling annual weeds of grassy and broad leaf nature. They can also be used at appropriate time.
  • Proper irrigation should be done from tillering to flowering stage because these are critical stages.
  • Water should be drained if sheath blight disease appeared.
  • Water should be drained out from the field 7 to 15 days before harvest depending on the soil type to encourage quick and uniform maturity of grains.
  • Harvesting should be done when 80 per cent panicle have about 80 per cent ripened spikelets.
  • At the time of harvest the upper portion of spikelets should be straw coloured and grain bill contain about 20 per cent moisture.

 

Don'ts in Rice

  • Don't delayed transplanting because it leads to poor tillering, early flowering of main tillers and reduction in yield.
  • Don't transplant single seedling in a hill.
  • Seedling should not be planted deeper than 2-3 cm because deeper planting delays inhibit tillering.
  • Fertilizers containing nitrate such as Calcium Ammonium Nitrate (CAN), Ammonium Sulphate Nitrate (ASN) and certain NPK complex fertilizers or mixtures should be avoided in paddy because loss of nitrogen in this form occurred due to leaching and denitrification.
  • Rock phosphate should not be applied in neuteral or alkaline soils.
  • Don't delay the harvesting of crop.
  • Moisture content in grain at time of harvesting should not be above 20 per cent.
