Direct-Seeded Rice Explained: Why Farmers Are Shifting Amid El Niño Monsoon Risk

Basic meaning: Direct-seeded rice, or DSR, is a paddy cultivation method in which rice seeds are sown directly in the field instead of transplanting seedlings from a nursery.

How it differs from transplanting: In conventional paddy farming, farmers first raise seedlings in a nursery, puddle the field with water, and then transplant young seedlings into the flooded field. In DSR, this nursery-transplanting step is avoided.

Simple example: Instead of first growing rice seedlings separately and then replanting them, a farmer uses a seed drill to place rice seeds directly into a prepared field.

Water stress: Paddy cultivation in Punjab, Haryana, western Uttar Pradesh and parts of Delhi-NCR depends heavily on groundwater. When the monsoon is uncertain, farmers look for methods that reduce irrigation demand.

Labour shortage: Manual transplantation requires a large number of workers within a short sowing window. DSR reduces dependence on transplanting labour.

El Niño concern: El Niño is associated with warming of the central and eastern equatorial Pacific Ocean and often weakens the Indian summer monsoon, though the relationship is not automatic every year. IMD has warned that El Niño conditions are likely to develop during the southwest monsoon season. (PIB / IMD)

Farmer economics: Lower water pumping and reduced labour requirement can reduce cultivation cost, especially where electricity, diesel, labour and irrigation are expensive.

Puddling meaning: Puddling is the process of repeatedly tilling a flooded field to make the soil soft and reduce water percolation.

Purpose: It helps transplant seedlings, suppress weeds and retain standing water in the field.

Water problem: Puddling itself consumes a lot of water. After transplantation, farmers often irrigate repeatedly to maintain standing water during the crop cycle.

Ecological cost: In areas where paddy is grown using tube wells, repeated flooding contributes to groundwater depletion and high electricity or diesel use.

No nursery-transplanting water: DSR avoids the nursery and transplanting stage, reducing the water used before crop establishment.

Less standing water: It does not require continuous flooding in the early crop stage if field moisture and irrigation are managed properly.

Efficient irrigation: DSR can be combined with alternate wetting and drying, laser land levelling, soil moisture monitoring and timely irrigation scheduling.

Scientific estimate: ICAR-IARI has stated that DSR can save approximately one-third of total water requirement under suitable conditions. (IARI)

Avoids transplanting labour: Traditional paddy transplanting is physically demanding and labour-intensive.

Mechanisation friendly: DSR can be done using seed drills, zero-till drills or other sowing equipment.

Shorter turnaround: In rice-wheat systems, faster rice sowing can help maintain the crop calendar and allow timely sowing of wheat after rice harvest.

Cost saving: Lower labour requirement is one of the main reasons farmers experiment with DSR during years of labour shortage or high wage pressure.

Core problem: Weeds are the biggest challenge in DSR because rice seeds and weed seeds germinate together.

Herbicide-tolerant varieties: These are rice varieties that can tolerate a specific herbicide, allowing farmers to kill weeds without damaging the rice crop.

IARI varieties: ICAR-IARI has developed non-GM herbicide-tolerant Basmati varieties such as Pusa Basmati 1979 and Pusa Basmati 1985, tolerant to Imazethapyr 10% SL for DSR cultivation. (IARI)

Non-GM nature: These varieties are described as non-GM because they were developed through conventional breeding and marker-assisted selection, not through transgenic genetic modification.

Basic meaning: Imazethapyr is a herbicide used to control weeds in certain crops.

Role in DSR: In herbicide-tolerant rice, it can be sprayed to control weeds while the rice crop survives.

UPSC caution: Herbicide tolerance is not the same as freedom to spray indiscriminately. Overuse or wrong use can create herbicide resistance, harm non-target plants, affect soil ecology and increase input dependence.

Stewardship need: Farmers need training on dosage, timing, rotation, safety and integrated weed management.

North-west India’s issue: The Green Revolution made Punjab, Haryana and western Uttar Pradesh major rice-wheat regions, but paddy expansion in semi-arid areas increased groundwater extraction.

CGWB concern: Groundwater assessment reports repeatedly show high extraction in north-western states, especially where paddy is cultivated with tube-well irrigation. (CGWB)

Policy relevance: DSR can reduce irrigation pressure, but it must be combined with crop diversification, water pricing reform, better procurement incentives and aquifer recharge.

Climate adaptation: DSR helps farmers adapt to uncertain monsoon conditions by reducing water dependence.

Climate mitigation: Flooded paddy fields release methane, a potent greenhouse gas. DSR can reduce methane emissions by avoiding prolonged flooding, although nitrous oxide management must also be considered.

Resource efficiency: It supports the idea of producing more with less water, labour and energy.

Food security: Since rice is central to India’s food security, climate-resilient rice cultivation is important for both farmers and consumers.

Weed infestation: Poor weed control can reduce yields sharply.

Soil suitability: Light-textured sandy soils may not retain enough moisture, while poorly levelled fields may create uneven germination.

Rainfall dependence: If sowing is followed by long dry spells or intense rainfall, germination and crop stand may suffer.

Skill requirement: DSR needs precise agronomy. It is not just “broadcast seed and wait”.

Herbicide dependence: Excessive reliance on herbicides may create environmental and resistance-related risks.

MSP assurance: Rice enjoys assured procurement in several states, especially Punjab and Haryana, which reduces market risk for farmers.

Public Distribution System: Rice is central to foodgrain procurement and distribution under food security programmes.

Input subsidies: Subsidised electricity and irrigation can hide the real cost of groundwater extraction.

Farmer risk calculation: Farmers prefer paddy because it has established markets, known practices and government support.

Diversification need: Paddy cannot be replaced overnight because it supports food security and farmer incomes.

Alternative crops: Maize, pulses, oilseeds, millets and horticulture may reduce water stress but need assured markets, processing, procurement, price support and extension.

Policy challenge: Farmers will not shift unless alternatives are as reliable as paddy in terms of income and procurement.

DSR as transition: DSR is a water-saving improvement within rice cultivation, but it is not a complete substitute for long-term crop diversification.

GS3 economy: It connects agriculture, irrigation, MSP, farm mechanisation, labour cost, productivity and rural livelihoods.

GS3 environment: It relates to groundwater depletion, methane emissions, climate change, El Niño and sustainable agriculture.

Governance: It requires coordination among ICAR, state agriculture departments, Krishi Vigyan Kendras, groundwater authorities, seed systems, subsidy policy and procurement agencies.

Prelims relevance: DSR, puddling, Imazethapyr, Pusa Basmati 1979, Pusa Basmati 1985, El Niño, MSP, Green Revolution and methane from rice fields are important factual triggers.

Promote DSR only in suitable areas: DSR should be encouraged where soil type, irrigation access, land levelling and farmer capacity support good crop establishment.

Strengthen extension services: Krishi Vigyan Kendras and state agriculture departments must train farmers in sowing depth, seed rate, irrigation timing and weed control.

Use integrated weed management: DSR should combine herbicide stewardship, crop rotation, stale seedbed technique, mechanical weeding and field monitoring.

Link DSR with groundwater policy: Water-saving paddy should be part of wider groundwater governance, including aquifer mapping, metering pilots, recharge and crop planning.

Improve seed availability: Certified seeds of suitable DSR varieties and hybrids should be made available before the sowing window.

Avoid one-size-fits-all promotion: DSR should not be imposed uniformly; local rainfall, soil, farmer experience and groundwater status must guide adoption.

Combine with crop diversification: DSR can reduce the ecological cost of paddy, but states must also create reliable markets for maize, pulses, oilseeds and millets.

Build climate advisories: IMD forecasts, soil moisture data, remote sensing and local advisories should guide sowing and irrigation decisions.
