Abstract

Abstract Glasshouse and field experiments with peanut crops show that concentration of Zn and B in the peanut plant leaf at pre‐flowering can be raised and the yield increased with the application of 20 Kg. Zn/ha and 1 Kg. B/ha, The proposed critical level for Zn and B in leaves for peanuts grown in the Punjab is 25 ppm.
