Influence of potassium nutrition on stomatal behaviour, transpiration rate and leaf water potential of pigeon pea (Cajanus cajan (L.) Millsp.) in sand culture

  • K Venkateswara Rao
  • K xxxV Madhava Rao


Pipeon pea seedlings were grown in sand culture using Hoagland solution with four levels of potassium. All measurements were made up to 37-day old seedlings. The influence of potassium nutrition on stomatal behaviour, transpiration rate and leaf water potential were observed and results are reported here.
