Abstract

Application of zinc significantly increased the dry matter production and its efficiency was magnified in the presence of iron. Addition of 5ppm Zn with 10ppm Fe through ferric citrate was even superior than 20 ppm Fe through ferrous sulphate applied with 5 ppm Zn to enhance the dry matter yield. Zinc and Fe applications significantly decreased the P concentration in all the plant parts and maximum reduction in P concentration was noted when 5 ppm Zn was applied alongwith 20 ppm Fe through ferrous sulphate. Zinc and Fe have more depressive effect on P absorption at the site of roots. Potassium concentration in all the plant. parts was increased by Zn application, The lowest K concentration value in roots and highest in shoots reflects the higher mobility of K from roots to shoots Ferrous sulphate has relatively more depressing effect on K concentration than ferric citrate.
