Abstract:

A detailed soil fertility status of the chickpea growing soils of owk mandal, Kurnool district (A.P) was investigated during 2017-18 to identify the soil related crop production constraints. Geo-referenced composite surface soil samples (0-15cm) were collected and analyzed for pH, EC, OC and available N, P, K. Almost all soils were moderately alkaline in reaction. The, electrical conductivity (EC) was within safe range for crops (<0.48 dSm-1). Soil organic carbon varied from 2.7 to 8.0 g kg-1 with a mean value of 5.3 g kg-1. The mean available soil N, P, and K was found to be 121.57, 45.43, 421.20 kg ha-1 respectively. Thematic maps were prepared for each soil parameter using ArcGIS package to provide the ready to understand information about soil fertility status and serve as a decision making tool for successful production of chickpea.
