Low soil pH and calcium (Ca) deficiency in both the root and pod-zone are important problems for groundnut production world-over on account of the light-textured nature of the soils suitable for its production. An experiment was conducted to examine

Most of the sandy soils that are suitable for production of groundnut (Arachis hypogaea L.) in the tropic and subtropics are acidic. Whilst effects of pH in the root zone have been studied, the effects of pod-zone pH on groundnut productivity remain
