Current responsibilities:

  • Identification and introduction of sorghum technologies in non-traditional sorghum area like rice-fallows under zero-tillage
  • Impact assessment of the demonstrated improved rabi sorghum technologies on farmers’ livelihood in major sorghum growing states of the country
  • Farmers’ livelihood enhancement through interventions of latest sorghum production technologies in different agro-eco systems of the country
  • Coordination of frontline demonstration programmes to evaluate and demonstrate latest sorghum technologies for wide adoption in different agro-eco systems of the country
  • Agro-ecology and constraints analysis of sorghum and small millets in constrained areas for livelihood betterment of tribal community

Recent 3 major contributions:

  • Identified promising sorghum hybrid CSH 16, suitable for rice-fallows in coastal Andhra Pradesh, out of thirty two public and private cultivars evaluated in the farmers’ fields. Six productivity factors viz., area under sorghum crop, cost of fertilizers, irrigation, pesticide, labourer and grain yield were contributed significantly in obtaining gross returns (R2=0.9668) to the farmers.
  • Latest kharif sorghum cultivars; CSH 23, SPH 1148, CSV 20, CSV 23, CSV 17, CSV 15, SU 1080, PJ 1430, JJ 1022, GJ 42, CoS 28, and CoS 30 were introduced in Maharashtra, Karnataka, Madhya Pradesh, Andhra Pradesh, Rajasthan, Gujarat and Tamil Nadu states through frontline demonstrations. They yielded 78% more grain and 60% stover than the local cultivars which were resulted into 51 per cent more net returns.
  • Demonstrated rabi sorghum cultivars viz., CSV 18R, CSV 22R, PKV Kranti, Phule Vasuda, Phule Yashodha, Phule Revati, Phule Chitra, Parbhani Moti and Parbhani Jyoti in major sorghum growing states Maharashtra, Karnataka and Andhra Pradesh. They gave 84% higher grain and 61% stover yields than the local checks, and obtained 50% more net returns.

Recent awards and recognitions:

  • Best Paper Award in International Conference on “Good Governance in Agricultural Extension” held at Centre for Good Governance, Hyderabad during 3-4 September, 2015
  • Young Scientist Award - 2014 of Society of Extension Education, Agra, India
  • Best Poster Award in Global Consultation on millets promotion for health and nutritional security organized by Society for Millets Research, Directorate of Sorghum Research, Hyderabad, India during 18-20, December, 2013.
  • Fellow Award - 2011 of Indian Society of Extension Education, New Delhi, India
  • Certificate of recognition for “Best Popularization Effort for Sorghum in Rice-fallows during 2009-10” from Directorate of Sorghum Research, ICAR, Hyderabad.

Current collaborative activities:

  • Coordinating frontline demonstration programmes on sorghum with different All India Coordinated Research Project on Sorghum (AICRPs)
  • Field evaluations of improved sorghum cultivation in collaboration with different AICRPs for socio-economic upliftment of tribal farmers under Tribal Sub-Plan programme
