Moong Sowing Season in India: Best Time to Grow Green Gram
Compare kharif, irrigated spring-summer and rice-fallow moong windows using variety duration, rainfall, soil moisture, irrigation and harvest weather.
Quick answer
Quick answer
Moong is sown in locally recommended kharif, irrigated spring-summer and some rice-fallow windows. The right date depends on an adapted variety, dependable moisture for emergence, drainage, expected heat and rain during flowering, and whether mature pods can be harvested in suitable weather. No single date or seed rate applies across India.
Key takeaways
- Moong calendars differ sharply by production system and region.
- Match maturity duration to the available moisture and harvest window.
- Summer irrigation cannot correct an unsuitable variety or extreme heat timing.
- Rice-fallow sowing relies on a specific residual-moisture system.
When is moong sown in India?
Direct answer: there is no single all-India date. Moong can be grown in kharif, irrigated spring or summer, and some rice-fallow windows. The right window depends on the locally recommended variety, rainfall pattern, heat, available irrigation and whether pods can mature in reasonably dry weather. Match the locally recommended variety to a window with workable soil moisture, drainage and enough time to mature before high harvest-time rainfall.
Crop practice changes with state, district, variety, season, soil test, rainfall and irrigation. Use the figures in this article as examples from named institutions, not as a universal prescription. Confirm seed, nutrient and crop-protection decisions with the current package of practices from your State Agricultural University, Krishi Vigyan Kendra (KVK) or agriculture department.
How do the main seasonal windows differ?
| Window | Moisture basis | Main planning question |
|---|---|---|
| Kharif | Monsoon rain and profile moisture | Will the crop establish after dependable rain without prolonged waterlogging? |
| Spring or summer | Pre-sowing and scheduled irrigation | Does an adapted short-duration variety fit between crops and avoid damaging heat or pre-monsoon rain at maturity? |
| Rice fallow or relay | Residual moisture in a locally defined rice system | Is the field, variety and sowing technique recommended for relay or post-rice establishment? |
These are planning categories, not fixed dates. ICAR-IIOR publishes a state-and-season table for sesame, while TNAU and PAU publish region-specific calendars for their production systems. That is why a nearby official advisory is more useful than copying a date from another state.
How does rainfall affect sowing time?
Rain is a field condition, not a date by itself
Rainfall matters through timing, intensity and distribution. Enough moisture is needed around the seed for uniform germination, but saturated soil can exclude air, increase crusting and expose seed or roots to decay. A single shower followed by a long dry spell may be less useful than a dependable moisture period.
Before sowing, inspect the profile at seed depth, check the short-range local forecast and make sure excess water has somewhere to leave the field. In rainfed fields, avoid sowing merely because the surface is wet while the layer below remains dry.
How do temperature and soil condition affect the decision?
Warm-season seed establishes poorly when soil is unusually cold, waterlogged, sealed or cloddy. Very hot, dry surface soil can also reduce emergence. The practical test is whether the field can be prepared and sown at uniform depth while keeping moisture around the seed without compaction.
What changes when irrigation is available?
Irrigation can support pre-sowing moisture and crop establishment, but it does not make every date suitable. Consider water quality, supply reliability, the heat expected at flowering, disease-favouring humidity and the risk of rain at maturity. Design beds or channels so a life-saving irrigation does not create prolonged standing water.
How do you choose the variety for a sowing window?
- List varieties officially recommended for the district and season.
- Compare maturity duration with the expected end of the moisture window.
- Check disease reaction and whether the variety is intended for rainfed, irrigated or rice-fallow production.
- For sesame, confirm seed colour and quality traits required by the buyer; for moong, confirm pod maturity and shattering characteristics.
- Buy labelled seed from an authorised source and retain the lot record.
What should be checked on sowing day?
- Seed lot, germination and treatment status
- Moisture at the intended depth
- Drainage outlets and field levelling
- Calibrated seed rate, depth and row placement
- Weather risk for emergence and the next field operation
- A written record of variety, date and field
Common sowing mistakes
Common failures include sowing too deep, placing seed unevenly, using an unsuitable variety, ignoring a compacted or waterlogged field, waiting so long that maturity meets heavy rain, and copying another region's seed rate or fertiliser schedule. Correct the system before increasing inputs.
How can you verify the local sowing window?
- Find the latest crop calendar or package from the State Agricultural University or agriculture department.
- Check that the named variety is recommended for the district and production system.
- Ask the KVK whether unusual rainfall, heat or a current pest advisory changes the normal window.
- Compare the varietal duration with the intended harvest period and the next crop.
- Record the source and year of the recommendation so an old calendar is not reused unknowingly.
If emergence fails, identify the cause before re-sowing. Dry seed depth, crusting, waterlogging, poor germination and insects require different responses. Re-sowing late with the same variety may push maturity into a worse window, so obtain local advice quickly.

Frequently asked questions
When is moong sown in India?+
Moong is grown in different kharif, spring-summer and rice-fallow windows. The exact date comes from the local package and variety recommendation.
When is summer moong sown?+
The window is regional. For example, PAU publishes a late-March to April window for its Punjab summer system; farmers elsewhere should not copy it without local confirmation.
Can moong be sown in standing rice?+
Some rice-fallow relay systems broadcast greengram before rice harvest under specific soil-moisture conditions. Use only a locally recommended variety and method.
How does rain affect moong sowing?+
Enough rain supports emergence, but saturated soil and ponding harm aeration and roots. Check moisture at seed depth and working drainage.
Can irrigation make any moong sowing date suitable?+
No. Variety duration, temperature, disease and insect pressure, preceding crop and harvest weather still determine whether a window is practical.
