Response of hybrid sorghum variety CSH-1 to application of Zn, Mn and Fe was studied on calcareous black soils of Vidarbha region by conducting field trials in the years 1972 and 1973. Their effect was also studied on biological quality of grain.
Application of Zn along with usual recommended doses of NPK fertilizers had substantially increased grain yield and improved biological quality of grain. Beneficial effect of Zn was further improved when Mn, which was marginally deficient, was also added alongwith. No such effect of application of Fe when given alone or in combination with Zn or Mn or both was observed.
