A well prepared and leveled field gives a uniform,healthy crop that can compete with weeds, uses less water and gives higher yields at a lower cost.
A well prepared field has:
- Many small soil clods to give good seed ‘soil contact’
- No weeds
- Harder layer at 10 cm to stop water percolation
- Level and smooth surface after puddling
- Well-constructed bunds
