Dry Direct Seeding Limitations

1. Good land preparation, levelling and water management are needed for uniform crop establishment. Weeds are a major problem and their control is critical to get high yield.

2. Problems of rats, birds, mole crickets, ants and Nematodes can also be a problem especially in non-flooded fields.

3. Heavy rainfall at the time of crop establishment can result in crop establishment failure (especially in heavier clay soils) and if water sits over seed still germinating below the soil.

Dry Direct Seeding in irrigated areas

1. Use less - 60-80 kg - of good seed of a variety suited for direct seeding. Fertilizer can be added as basal.
2. Irrigate after sowing (if no rain). Let the water drain before flash flooding after 2-3 days to keep seed moist and to reduce soil crusting (this is especially important in the dry season).
3. If water is drained from the fields after broadcasting, it is re-introduced 10 to 15 days after the crop is established.

Dry Direct Seeding in rainfed systems

1. Small outlets can be made across the field to help drain the field and avoid snail damage and seed emergence problems in areas where water may stand.

2. Use sufficient seed of a variety suited for direct seeding to achieve a plant population of 100-150 plants/m2. This will usually require around 120-150 kg seed/ha. Farmers often use more seed (e.g., up to 150-200 kg/ha) because of poor field levelling, poor seed and seed loses to birds and rats.

3. Sow the seed uniformly. For

Why use Dry Direct Seeding?

1. Transplanted rice has deleterious effects on the soil environment for the succeeding rice and other upland crops. Direct seeded rice which removes puddling and drudgery of transplanting.

2. The young rice seedlings provides an option to resolve the adaphic conflict and enhance the sustainability of cropping system.

3. Puddling requires lots of scarce water at a time when there is little water in the reservoirs, destroys soil structure and adversely affects soil
