ABSTRACT

A survey was undertaken to study the nutrients status of groundnut growing soils in eastern mandals of Chittoor district of Andhra Pradesh. The texture of the soils varied from sandyloam to sandy clay loam, neutral to slightly alkaline in reaction, non-saline, low to medium in organic carbon and available nitrogen and medium to high in available P and K. However, available Ca, Mg, S, Fe, Mn, Zn and Cu were found to be above critical limits in all the soils. Simple correlation studies revealed that available N, S, Fe, Mn, Cu and Zn were positively and significantly correlated with clay content and organic carbon. However, available P, K, Ca and Mg were negatively and significantly correlated with clay content.
