Professional Information

Contribution to the scientific advancement

  • Identified the period of defoliation to prevent flowering in sugarcane as it is undesirable for quality parameters.
  • Identified the leaf sheath moisture is the main cause for Banded Sclerotial disease in sugarcane.
  • Seed priming of rice seed with KNO3(0.25%) followed by seed coating with complete Hoagland solution (@05ml/kg seed) significantly enhances the seed quality parameters, growth and field performance of rice crop.
  • Seed priming of moong bean seeds (Samrat, Sulabh and SML668) with Mg(NO3)2 @30mM concentration significantly enhances seed germination, seedling growth, vigour index 1 & 2, yield attributes and yields.
  • Under salt affected soil seed priming of wheat seeds with Kinetin @100ppm for 12h period significantly enhances the seed quality parameters, growth and finally yield attributes and yield in wheat crop.
  • Identified the Pigeon pea genotypes for cold tolerance..
  • Served as Incharge/Nodal Officer of PME Cell, RFD, PERMISNET, HYPM, PULSE SEED HUB, Institute farm at IISS, Mau.
  • Served as Chief editor of Raj Bhasha Patrika BEEJ and Prasar Patrika.
  • Served as Chief editor of Institute Annual Reports.
