Bringing Green Revolution in Eastern Region

Increasing rice production in Eastern India by promoting hybrid rice as well as other technologies

Dr. B. C. Viraktamath

Project Director

Directorate of Rice Research


Slide2 l.jpg

Region -wise rice area, production and productivity (mean of 2002-2007)

Eastern India has the great potential to enhance rice production in the coming years


Slide3 l.jpg

Rice Area (%) in Eastern region – Ecology-wise

Floating

Deep water

Semi-deep water

Upland

Rainfed lowland

Total area = 23.4 Mha



Slide5 l.jpg

State-wise rice area, production and productivity during 2005-2006(In Eastern region)


Slide6 l.jpg

  • Production constraints in Eastern India

  • Physical

  • Over dependence on unpredictable monsoon

  • Frequent drought/floods

  • Low light intensity during kharif

  • Technical

  • Slow spread of HYV’s

  • Lower use of fertilizers/other inputs

  • Low seed replacement rate

  • Extension

  • Weak extension machinery

  • Lower credit facilities

Bringing Green Revolution in

Eastern India

“Green Revolution in eastern India should be ushered in based on the principles of sustainability, soil health and environmental protection”

Increasing the yields should not be the only criteria that has derailed the sustainability of rice production system


Slide8 l.jpg

Bringing green revolution to the east : needs caution

  • Lessons learnt from green revolution in other parts of the country

  • Over-emphasis on input intensive technologies

  • Excessive and imbalanced use of chemical fertilizers leading to micro nutrient deficiencies

  • Neglecting the use of organics in rice cultivation

  • Excessive exploitation of ground water leading to soil problems

  • Over dependent on chemical based pest control leading to environmental pollution

  • Benefited only the medium and large farmers


Slide9 l.jpg

Strategies for bringing green revolution in Eastern India

  • Adoption of new high yielding varieties

  • Strengthening seed production and encouraging seed replacement rate

  • Increasing area under hybrid rice

  • Encouraging balanced use of fertilizers (INM, SSNM)

  • Enhanced use of organics

  • Adoption of IPM practices to control pests/diseases

  • Increasing irrigation facilities and judicious use of water

  • Increasing area under boro rice wherever ground water is abundant


Slide10 l.jpg

Adoption of High Yielding Varieties in Eastern India

IR-Irrigated; RSL-Rainfed shallow lands; RUP-Rainfed uplands;




Slide13 l.jpg

Hybrid Rice India

One of the key components that can help in bringing green revolution to Eastern India. The potential is seen already as the region is leading in hybrid rice cultivation.


The need for hybrid rice l.jpg
The Need for Hybrid Rice India

  • Rapidly increasing population

  • Plateuing yield trend of HYV’s.

  • Declining resources (Land, Water)

  • Yield advantage of hybrids (15-20%) over varieties

Hybrid Rice is one of the practically feasible and readily adoptable technologies to enhance productivity of rice in the country.

Eastern India: Harbinger of hybrid rice cultivation India

  • Appreciable yield advantage of the hybrids over the inbred varieties (30-40%)

  • Farmers’ enthusiasm in accepting the technology

  • Hybrid rice quality suiting to the requirement of the people in the region

  • Aggressive marketing strategies by the private seed companies


Slide16 l.jpg

Evaluation of Hybrids India

• Total hybrids evaluated : 2000

• Hybrids Released : 43

• Public Sector hybrids : 28

• Private Sector hybrids : 15

• Central Releases : 20

• State Releases : 23

Hybrids available for cultivation in different states India

Besides private sector is selling 30-40 non notified hybrids in the region



Slide23 l.jpg

Hybrids suitable for rainfed/aerobic conditions India

Hybrids tolerant to salinity/alkalinity


Slide24 l.jpg

Strategies for promoting Hybrid rice in Eastern India India

Policy

  • Providing a special fund for hybrid rice research with special focus on Eastern India

  • Constituting a task force to oversee the progress on hybrid rice

  • Creating conducive environment to boost seed production both by public and private sector

  • Procurement of hybrid rice produce by FCI and other agencies for PDS

Contd….


Slide25 l.jpg

Technical India

  • Development of long duration hybrids for shallow low lands and coastal areas

  • Further enhancing the level of heterosis

  • Optimizing hybrid rice seed production in boro areas

Extension

  • Conducting large number of demonstrations in farmers’ fields

  • Line Departments to play a key role in promoting hybrid rice

  • Advance seed indent system to be developed and implemented


Slide26 l.jpg

Other technologies to usher into green revolution in Eastern India

  • Adopting Integrated Nutrient Management practices

  • Going for soil health cards and practicing site specific nutrient management

  • Use of organics/green manures should be an integral part in rice cultivation

  • Use of Leaf Colour Chart to improve the ‘N’ efficiency

  • Crop diversification (rotation and recycling of crop residues)

  • Judicious use of water by adopting innovative cultivation methods

  • Integrated pest management


Slide27 l.jpg

Adoption of SRI to save water and other inputs India

  • Plant young seedlings (8-12 days old)

  • Single seedling per hill with soil

  • Wider spacing (20 x 25 cm)

  • Use of more organics

  • Weeding by cono weeder

  • Bio-pesticides (IPM)


Slide28 l.jpg

Aerobic rice cultivation India

  • Cultivation of rice in un puddled, direct seeded without standing water (need based irrigation as like wheat & maize)

  • Combines features of high yielding irrigated lowland and drought tolerant upland cultivars.

Slide31 l.jpg

Trap Crop- A cost effective environmental friendly way to control the stem borer

Growing one row of Basmati variety after every 9 rows of farmers’ variety could reduce the stem borer damage to considerable extent


Slide32 l.jpg

Conclusions control the stem borer

  • Faster spread of newly developed varieties and hybrids

  • Efficient and effective seed production mechanism to ensure the availability of quality seeds

  • Selective mechanization to save the rice farming from labour shortage

  • Enhancing profitability of rice farming by economizing the input use

  • Intensifying research on water saving technologies such as Aerobic rice, AWD, SRI etc

  • Aggressive technology transfer efforts by all the concerned
