Preliminary Investigation of a 'Peg Drying' Problem of Groundnut uri icon

abstract

  • In a pot experiment the problem of groundnut 'peg drying' where plants were slightly stunted with mottled leaves and blackened pegs and pods was investigated. Soil from the affected fields was used and plants were treated with dibromochloropropane or Vitavax (carboxin) and given 1.43 mg boric acid/kg soil and/or 0.5 g calcium sulphate/kg soil. Peg tips were blackened in all treatments to varying degrees. Plant growth was slightly improved by the nematicide but not by the fungicide which caused phytotoxic effects. Plant growth, root mass, number of pegs and pods and pod filling were improved by calcium and/or boron application
