What is Direct Seeded Rice (DSR) method? Blog Image

Overview:

Punjab Government has set a target of five lakh acres to be sown under direct seeded rice (DSR) method of paddy cultivation this kharif season.

About Direct Seeded Rice (DSR) method:

  • DSR, also called the ‘broadcasting seed technique’, is a water-saving method of sowing paddy.
  • Seeds are directly drilled into the fields in this method.
  • This saves groundwater, as opposed to the traditional water-intensive method, under which rice seedlings are transplanted from a nursery to waterlogged fields
  • With DSR technique, farmers must sow paddy only after pre-sowing (rauni) irrigation and not in dry fields. Further, the field should be laser levelled.
  • Advantages:
    • No significant reduction of yield under optimal conditions;
    • Savings on irrigation water by 12-35% under efficient water management practices;
    • Reduces labor and drudgery by eliminating seedling uprooting and transplanting;
    • Reduces cultivation time, energy, and cost;
    • No plant stress from transplanting;
    • Faster maturation of crops;
    • Lower GHG emissions;
    • Mechanized DSR provides employment opportunities;
    • Increases total income by reducing the cost of cultivation;
  • Current Constraints:
    • Higher seed rates;
    • Seeds exposed to birds and pests;
    • Weed management;
    • Higher risk of lodging;
    • Risk of poor or non-uniform crop establishment;

 The ‘rauni’ method is referred to the technique in which a pre irrigation is applied in order to get the optimal moisture conditions and prepare a fine seedbed for wheat planting and seed is sown either by broadcasting or planted in row with a seed drill or other implements and manners.
