As wheat sowing begins across key producing states, agronomists are stressing that field preparation—not seed quality alone—will decide yield outcomes this rabi season. With rising input costs, uneven monsoon withdrawal, and tighter sowing windows, getting the soil ready on time has become more critical than ever. Extension agencies are advising farmers to focus on moisture conservation, proper tillage depth, and balanced nutrient correction before the first irrigation. These steps, if done correctly, can improve germination, reduce weed pressure, and support uniform crop growth through winter.
Below is a practical, field-tested guide to preparing land for wheat sowing under Indian conditions.

Understand the Current Soil Condition Before Tillage
Field preparation should start with a quick assessment of soil status rather than routine ploughing. Many wheat fields today follow rice, maize, or cotton, each leaving different residue and compaction issues.
Key checks to make:
Soil moisture: The field should be workable, not sticky or powder-dry.
Compaction: Hardpans from repeated shallow tillage reduce root growth.
Residue load: Rice stubble and weeds must be managed early.
If soil is too wet, delay tillage to avoid clod formation. If too dry, pre-sowing irrigation may be necessary to bring soil to workable condition.
Primary Tillage: Create a Loose but Stable Soil Base
Primary tillage is aimed at loosening soil and breaking compaction, not over-pulverising it. Experts now recommend reduced but effective tillage, especially where fuel costs are high.
Recommended practices:
One deep ploughing (20–25 cm) using mouldboard or disc plough if compaction is present
Follow with 1–2 harrowings or cultivator passes
Avoid excessive tillage that destroys soil structure
In rice–wheat systems, shallow tillage combined with residue incorporation is increasingly preferred to protect soil health.
Level the Field for Uniform Germination and Irrigation
Uneven fields cause water stagnation in some patches and moisture stress in others. This directly affects germination and early tillering.
Best practices:
Use a laser land leveller where available
Ensure gentle slope for proper drainage
Remove leftover bunds and channels from the previous crop
Well-levelled fields reduce irrigation water use by up to 20 percent and improve fertiliser efficiency.
Manage Weeds and Crop Residue Before Sowing
Early weed control during field preparation reduces herbicide dependence later. Weeds emerging before sowing compete for moisture and nutrients.
What works now:
Remove or incorporate weeds during tillage
Chop and spread rice residue evenly instead of burning
Use residue management implements if sowing with seed drills
Burning crop residue is discouraged due to soil nutrient loss and regulatory restrictions in many states.

Apply Organic Matter and Basal Nutrients Correctly
Soil fertility correction before sowing is more effective than later top-dressing alone. Agricultural universities recommend applying organic inputs at this stage wherever possible.
Before final land preparation:
Apply well-decomposed FYM or compost (5–10 tonnes/ha)
Incorporate crop residues to improve soil carbon
Apply basal dose of phosphorus and potassium as per soil test
Avoid applying fresh manure immediately before sowing, as it can increase pest and disease risk.
Final Seedbed Preparation: Fine, Firm, and Moist
The final pass should prepare a seedbed that allows good seed–soil contact without compaction. This step is often rushed but has a major impact on germination.
Ideal seedbed conditions:
Soil clods broken but not powdery
Moisture present at sowing depth
Surface firm enough to hold irrigation water evenly
Rolling or light planking after the last tillage helps settle soil and conserve moisture.
Adjust Preparation Based on Sowing Method
Field preparation should match the sowing method being used.
For common methods:
Broadcasting: Requires finer tilth and extra levelling
Seed drill sowing: Moderate tilth with residue clearance
Zero tillage: Minimal disturbance, weed control before sowing is essential
Zero till wheat is expanding in north India due to cost savings and timely sowing, but it demands precise weed and moisture management.
Conclusion: Field Preparation Is a Yield Decision, Not a Routine Task
Preparing a field for wheat sowing is no longer a mechanical process—it is a yield-defining decision. With climate variability, rising costs, and tighter sowing windows, farmers who focus on soil condition, moisture balance, and precise land preparation are better positioned for stable yields. Timely, well-planned field preparation improves germination, reduces weed pressure, and sets the crop up for efficient nutrient use throughout the season. For wheat, what happens before sowing often matters more than what comes after.
FAQs
1. When should field preparation for wheat begin?
Field preparation should start immediately after harvesting the previous crop, ideally 15–20 days before wheat sowing, to manage residues and conserve soil moisture.
2. How many ploughings are required for wheat?
One deep ploughing followed by 1–2 harrowings is usually sufficient. Excessive tillage should be avoided as it damages soil structure.
3. Is land levelling really necessary for wheat?
Yes. A well-levelled field ensures uniform irrigation, better germination, and efficient fertiliser use, which directly affects yield.
4. Can wheat be sown without ploughing?
Yes. Zero-tillage wheat is widely practiced, especially after rice, but it requires proper weed control and suitable sowing equipment.
5. Should fertilisers be applied during field preparation?
Phosphorus, potassium, and organic manure should be applied before the final tillage, based on soil test recommendations.
