1. Good land preparation, levelling and water management are needed for uniform crop establishment.
2. Weeds are very serious in dry seeding and serious in wet seeding.
3. Snails (in wet seeded fields), and rats and birds can severely reduce plant stands.
4. 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.
5. Longer occupation of main field by 5
1. Ensure the field is well levelled, well puddled and weed free.
2. 2-5 days after the final puddling, the soil has settled to be solid enough to hold seed on or near the surface and weeds have not yet established.
3. In drained fields, small outlets can be made across the field a couple of days after puddling to further help drain the field and avoid snail damage and seed emergence problems in areas with standing water.
4. Pre-germinate the seed (soak for 24 hours in water, cover a
1. Easier (less drudgery) and more timely crop establishment.
2. Reduced labour costs for crop establishment.
3. Possible savings in water use.
1. In wet direct seeding, seed is normally pre-germinated prior to broadcasting onto recently drained, well-puddled seedbeds or into pre-standing water in the fields.
2. Wet direct seeding more commonly used in irrigated areas.
