The document discusses on-farm research and trials on aerobic rice technology aimed at enhancing rice production under drought and flood-prone conditions in Uttar Pradesh, India. It highlights various hybrids' performance, integrated crop management practices, and the benefits of adopting aerobic rice cultivation, such as water conservation and improved yields. Key findings indicate that specific hybrids like pac 837 and loknath 505 show better performance in terms of drought tolerance and higher grain yield.

19. Aerobic Rice ?
• Rice production technology, in which
paddy seeds are direct seeded in
unpuddled aerobic soils, and crop is
grown with higher inputs of fertilizer,
weedicides and irrigation to achieve
higher yields.
• Growing rice like wheat

20. Plant type and traits for aerobic rice
cultivars
i. Drought tolerance: germination, vegetative and
reproductive stage
ii. Semi-dwarf or intermediate height hybrids or varieties
iii. Thick & deep root system
iv. Duration: 110- 135 days, depending on rainfall pattern
v. Early seedling vigor to compete with weeds
vi. Non lodging at higher N levels (100:50:50 Kg NPK)
vii. Resistance/ tolerance to diseases like leaf and panicle
blast, brown spot, sheath rot, grain discoloration etc.
viii. Yield potential: >5 tha-1

21. How it differs from Upland rice?
i. Yield Potential: uplands cultivars yield up to
3.0 tha-1
ii. Non responsive to higher Nitrogen above 40
Kg
iii. Intermediate/ taller lodging type plant type

22. How it differs from direct seeded rice?
• Direct seeding can be upland, rainfed lowland,
& Deep water rice as dry direct seeded, but
aerobic rice is moist or dry seeded
• Aerobic rice is partially irrigated, while others
are rainfed.
• Direct seeding can be done in irrigated
puddled condition , but aerobic rice is grown
under unpuddled aerobic soils.

23. Why Aerobic rice ?
• Climate change & Climatic variability:
Increasing soil and atmospheric temperature
• El Nino in 2002, 2009, 2014 & 2015
• Delay in monsoon at seeding & transplanting
• Irregular rainfall distribution
• Not enough rain for puddling
• Reduced rice area due to insufficient rain
• Early, mid season , or late drought
• New rice production technology for drought
mitigation
