Abstract:
Groundnut-growing soils of Srikalahasti division in Chittoor district of Andhra Pradesh were evaluated for their suitability to groundnut crop. These soils belong to Entisols, Inceptisols and Alfisols. The soil-site suitability evaluation of the study area revealed that P2, P3, P4 P5, P7, P10, P13, P14, P16 and P17 were suitable (S1) for growing groundnut crop with slight limitations of pH, wetness and organic carbon. P1, P6, P8, P12, P15, P18 and P20 were moderately suitable (S2) with moderate limitations of wetness, soil depth and slight limitations of sum of basic cations, organic carbon, pH and alkalinity. P9, P11 and P19 were marginally suitable (S3) with moderately limitations of pH, soil depth and organic carbon for growing groundnut crop. Crop suitability evaluation revealed various limitations for growing groundnut crop in the study area. By correcting these limitations by following suggested said management practices, sustainable yields can be achieved in groundnut crop besides sustaining the soil fertility.
