Current responsibilities:

  • All India Coordinated Research Project on Sorghum related multi-location experimentation.
  • Institute project “Optimization of the potential productivity of small millets and assessing the physiological basis of sustaining Finger Millet Yield in a rainfed environment”
  • DBT funded project “Commercialization of sweet sorghum as a complimentary feedstock for ethanol production in the sugar mills of Maharashtra, Tamil Nadu and Gujarat”.

Recent major contributions:

  • Improved NUE in rabi sorghum: Bringing about the interaction of applied fertilizer with available soil moisture through the deep placement management strategy helped improve the spikelet number and spikelet weight. Improvement in yield components helped increase the grain yield and in turn the agronomic nitrogen use efficiency. Annual and seasonal rainfall which help replenish the stored soil moisture could be utilized efficiently through the nitrogen management intervention. The hypothesis that improved water use efficiency in a rainfed rabi environment characterized by receding stored soil moisture can be brought about by deep placement of N fertilizer in rabi sorghum was validated.
  • Development of low lignin high biomass sorghums for bio-fuel production: Second generation biofuels would facilitate blending of petrol with ligno-cellulosic ethanol, produced from high biomass sorghums. Competitiveness and economic returns are two important criteria that drive any innovative application by enterprises. Sorghum with the potential for high biomass production can be competitive through exploitation of important traits like photosensitivity and low ligno-cellulosic content. The physiological basis of biomass production as well as the biomass production potential of selected sorghum genotypes was validated.
  • Decadal analysis of Sorghum Cultivar response to fertilizer application: Proportional increase in grain yield (due to application of external fertilizer input) over the control was linearly related to the N fertilizer use efficiency. Fertilizer N-use efficiency (DY/DN) defined as change in yield for every unit of applied N increased from 10 kg grain to 20 kg grain/kg of N applied. Hence, increase in productivity can be brought about both by genetic improvement as well as associated nutrient management intervention in a rainfed environment.
