Harvesting of transplanted hybrid rice

1.Taking the average duration of the crop as an indication, drain the water from the field 7 to 10 days before the expected harvest date as draining hastens maturity and improves harvesting conditions.

2. When 80% of the panicles turn straw colour, the crop is ready for harvest. Even at this stage, the leaves of some of the varieties may remain green.

3. Confirm maturity by selecting the most mature tiller and dehusk a few grains. If the rice is clear and firm, it is in hard dou

Precautions for irrigation in transplanted hybrid rice

The field plot can be 25 to 50 cents depending on the source of irrigation.

  • Field to field irrigation should be avoided. Field should be irrigated individually from a channel.
  • Small bund may be formed parallel to the main bund of the field at a distance of 30 to 45cm within the field to avoid leakages of water through main bund crevices.
  • To minimize percolation loss, the depth of stagnated water should be 5cm or less.
  • In water logged condition, form open dra

Water management in transplanted hybrid rice

1. Puddling and leveling minimizes the water requirement.

2. Plough with tractor drawn cage wheel to reduce percolation losses and to save water requirement up to 20%.

3. Maintain 2.5cm of water over the puddle and allow the green manure to decompose for a minimum of 7 days in the case of less fibrous plants like sunnhemp and 15 days for more fibrous green manure plants like Kolinchi (Tephrosia purpurea).

4. At the time of transplanting, a shallow depth of 2cm of water is
