Knowledge Nugget: How direct seeded rice could be the future of rice farming

2. Direct seeding can be accomplished by sowing pre-germinated seed into wet soil (wet seeding via broadcast or drum seeder) or by planting dry seed (dry seeding by broadcast and seed-cum-fertilizer drill) on prepared ground.

How does DSR work?

3. Traditionally, paddy farmers create nurseries where seeds are first planted. After 25–35 days, the immature plants are plucked and transplanted in the flooded main field. While this practice is labour and water expensive, it is known to increase yields and improve crop health.

4. DSR, as the name suggests, requires no nursery preparation or transplantation. Paddy seeds are directly sown, roughly 20-30 days prior to when they would have been transplanted. The field is irrigated and laser leveled prior to the seeding process which is carried out using a seed drill or lucky seeder. Seed treatment is crucial, with seeds soaked in a fungicide solution for eight hours, then dried for half a day before sowing.

5. The first round of irrigation is carried out 21 days after sowing, followed by 14-17 more rounds at 7-10 day intervals, depending on soil type and the quality of the monsoon. The final irrigation takes place 10 days before harvest. The traditional method requires 25-27 irrigations in total.

What are the benefits of DSR?

6. Direct seeding of  rice provides several benefits such as: 

(i) It can reduce water use by 15% to 20% (the traditional puddling method requires 3,600 to 4,125 litres of water to grow a single kilo of rice).

(ii) DSR requires less labour.

(iii) It matures 7 to 10 days faster, giving farmers more time to manage paddy straw.

(iv) It offers low production cost

(v) DSR provides better soil physical conditions for following crops and less methane emission.

What are the challenges associated with DSR?

7. Weeds are the biggest significant impediment to the success of DSR. Weeds are more problematic in DSR than in puddled transplanting because sprouting weeds compete with simultaneously emerging DSR seedlings.

8. While direct planting can help to reduce methane emissions, aerobic soil conditions can also increase nitrous oxide emissions. Nitrous oxide generation increases with redox potential.

9. Micronutrient deficiencies are a prominent cause of concern in DSR such lack of iron content of the soil can severely impact yields and lead to major financial losses for farmers.

What is the status of Rice production in India?

10. In January 2026, the Union Agriculture Minister Shivraj Singh Chouhan said that with the production of around 150 million metric tonnes of rice, India has surpassed China which produces 145.28 million tonnes to become the world’s largest rice producer in 2024-25.

11. Rice crop requires hot and humid conditions, abundant water availability, and alluvial soil (soil formed by the deposition of silt brought by rivers). River flood plains are among the most rice productive regions.

12. A temperature range of 20-37.5 degree celcius is required for its optimum growth. It is grown both during the kharif (southwest monsoon) and rabi (winter-spring) seasons. Moreover, it is cultivated across a wide geography.

BEYOND THE NUGGET: What is India’s Designer Rice?

1. Scientists at CSIR – National Institute for Interdisciplinary Science and Technology (NIIST) in Thiruvananthapuram, Kerala, have developed a “designer rice”. During the technology transfer ceremony held on 18th February, 2026, titled “CSIR-NIIST Tech Connect: From Lab to Market”, the rice was officially released.

2. The scientists have applied food-processing technology rather than genetic modification to bring this designer rice.  It is a “fundamental re-architecture of our most basic staple”.

3. Dr C. Anandharamakrishnan, Director, CSIR-NIIST and the visionary behind the project, noted, “To understand this, imagine a building. If traditional rice is a house made mostly of ‘sugar bricks’ (starch), the CSIR-NIIST team took that house apart. They removed a significant portion of the starch and replaced it with ‘protein beams’.”

4. The team took broken rice ground them into flour, and blended them with protein and micronutrients like iron, folic acid, and Vitamin B12. They then “reformed” this mixture into grains that look, feel, and taste exactly like the rice we know.

5. Benefits of the Designer rice

* Low GI: According to the scientists, designer rice benefits as it has a low glycemic index(GI) which is below 55. “It releases energy slowly, preventing the sugar spikes that plague diabetics.”

* Protein powerhouse: While normal rice has about 6–8 per cent protein, this version boasts over 20 per cent.

* Fortified defense: It bridges the gap for anaemia by embedding iron, folic acid, and Vitamin B12 directly into the grain’s structure.
