Abstract:
Sesame is an important oilseed crop predominantly grown in Adilabad, Nizamabad and Karimnagar districts of Telangana state. Investigating the fertility status of sesame growing soils is required to under pin future land use planning. A survey was carried out in major sesame growing soils of Northern Telangana Zone of Telangana state. 30 representative surface soil samples (0-15 cm) were collected and analysed for their salient characteristics viz., pH, EC, OC, available N, P₂O₅, K₂O. Results revealed that, soil pH ranged from 5.35 to 8.41 (slightly acidic to slightly alkaline). The soils were non-saline to slightly saline (0.16 to 0.92 dSm^-1). The organic carbon ranged from 0.15 to 0.75 g kg^-1 (low to medium). With regard to available nutrients, the values varied from 115.25 to 239.55 kg ha^-1 for nitrogen, 28.25 to 75.63 kg ha^-1 for phosphorus, for potassium 292.15 to 452.82 kg ha^-1.
