  • One of the eminent scholars of our time, Padma Shri Prof. Siddiq writes for RKMP on "Rice Research in India" covering various aspects. This comprehensive paper covers different facets of rice research carried out in India since Independence. While going through this paper, we hope that you will experience the transformation that the country has seen in last five decades.

  • Conclusion

               Excessively magnifying the shrinking pace of the favourable growth factors of the early decades of the Green revolution era and citing rapidly declining trend of production-productivity growth since early 1990s and no appreciable reduction in population growth, some apprehend that the country would be pushed back to the era of chronic food/rice deficiency in a few decades from now necessitating import of food...

  • Innovative approaches to find new yield thresholds

    Breeding efforts for yield enhancement have so far been through exploitation of easily accessible yield influencing variability resulting in dwarf plant type and new plant type based high yielding varieties and higher yielding hybrids in such plant type backgrounds, In search and use of yield related variability, efforts have so far been confined to cultivar genepool. It is the perception that needed variability is...

  • Varietal technologies of new yield threshold
    Since the introduction of dwarf high yielding varieties, breeding emphasis has been to sustain the yield gain achieved by progressively improving them with ability to defend themselves against yield destabilizing factors, especially biotic stresses exploiting hostplant resistance. While breeders have succeeded in sustaining the potential of the semidwarf high yielding varieties, progress in enhancing their genetic yield...

  • Exploitation of boro and shallow lowland ecologies

            Boro is the most productive season for rice in the eastern states. Boro rice yields about two times than that of kharif. Over 2.5 million hectares spread over 25 districts in the states of West Bengal, Assam, Bihar, Orissa, Eastern Uttar Pradesh and Northeastern states are suitable for boro rice. Such a large and productive season did not, however, receive due attention for long because of...

  • Intensification and diversification of cropping

    Varieties of the Green Revolution era have been not only high yielding but also of high per day productivity. Being of short duration and duration bound, they enabled double cropping of rice in single cropped areas and triple cropping in double cropped areas, where season is favourable and water is not limiting. In the traditional rice growing southern and eastern states rice-rice and rice-rice-rice/pulse or oilseed are...

  • Technologies for sustained production growth - Narrowing of yield gap

    India has been successful in raising the genetic yield of rice twice through introduction of plant type based high yielding varieties since mid 1960s and exploitation of hybrid vigour since early 1990s. It is sad that on both the occasions, we failed to harness the full potential of the new varietal technologies given the wide yield gap seen...

  • Opportunities and strategies

    Problems are not without opportunities and strategies to find solution. Unexploited and under-exploited technological and developmental opportunities capable of meeting the future demand projections are still many. They broadly include (a) wide gap between achievable and actually farmer achieved yields across all major rice ecologies (b) prospects of increasing cropping intensity in the relatively risk-free irrigated and mainly irrigated...

  • Demand projections and prospects of achieving

              Primarily based on the actual consumption visa vis population growth and rising per capita income as well as the need to take into account the growing export prospects and maintenance of the stipulated bufferstock, rice demand in the next 10-20 years, though estimated variedly by economists, would be no less than additional 20 and 35 million tonnes respectively over and above what is...
