Abstract: Rain-fed agriculture productivity is crucial for food security and economy of the state. To characterize the fertility status of soils under dry-land agriculture in the semi-arid regions, 110 soil samples were collected from Nagulapally-Konapur Model Watershed area in Medak district of Telangana to diagnose the deficiencies of macronutrients like Potassium, Sodium and Sulphur and micronutrients like Boron and Zinc. A summary of the chemical analysis of soil samples covering the watershed area showed that the farmer’s fields sampled had a wide range in pH and EC and they were low-to-moderate in organic carbon, generally adequate in exchangeable potassium and sodium. However, the most revealing results on soil chemical analysis were the widespread deficiencies of levels of extractable phosphorous (P), sulphur (S), boron (B) and zinc (Zn) in the samples. GIS mapping of the estimated fertility parameters was carried out using Arc GIS software to understand the occurrence of deficiencies of micronutrients over the watershed area under study. On-farm participatory trials were conducted for selected rainfed crops to study the impact of balanced nutrition (BN) on crop productivity over farmers practise (FP).
