Abstract:
A field experimentation was conducted during rabi season, 2020-21 at Instructional farm, School of Agriculture, GIET University, Gunupur, Odisha, to analyze the impact of various sources of sulphur on growth parameters and yield of sunflower under red and lateritic soils of Odisha. The experiment design was Randomized Block Design (RDB) and replicated thrice with seven treatments i.e. T₁ - Control, T₂ -20 kg sulphur/ha through ammonium sulphate, T₃ -20 kg sulphur/ha through elemental sulphur, T₄ - 20 kg sulphur/ha through gypsum, T₅ -20 kg sulphur/ha through ammonium sulphate +20 kg sulphur/ha through elemental sulphur, T₆ -20 kg sulphur/ha through elemental sulphur + 20 kg sulphur/ha through gypsum, T₇ -20 kg sulphur/ha through gypsum + 20 kg sulphur/ha through ammonium sulphate. The outcome revealed that combined application of 20 kg sulphur/ha through gypsum and 20 kg sulphur/ha through ammonium sulphate (T₇₎ recorded higher growth attributes and yield of sunflower over other treatments.
