Impact of Different Sources of Phosphorus and Sulphur Levels on Growth, Yield Attributes and Performance of Chickpea under Light Textured Soil

Background: Pulses are most important source of dietary protein, belonging to the family of Leguminosae and strictly harvested for their dried seeds. Phosphorus and sulphur nutrients play a vital role in quality production and nutritional values. Phosphorus rich organic manure (PROM) have potential to release organic acids to enhance native soil phosphorus mineralization.

Methods: This investigation was carried out at Instructional Farm, College of Agriculture, Swami Keshwanand Rajasthan Agriculture University, Bikaner during Rabi season of 2021-22 with the use of different levels of phosphorus and sulphur to investigate the growth rate, yield parameters and performances of chickpea. The experiment was laid out in factorial randomized block design comprising three phosphorus sources with a certain amount of 32 kg P ha-1 through di ammonium phosphate (DAP), single super phosphate (SSP) and PROM and four sulphur levels (control, 20, 40 and 60 kg ha-1) and it was replicated thrice.

Results: The application of 32 kg P2O5 ha-1 through PROM significantly increase higher growth parameters, yield attributes and yield in comparison to 32 kg P2O5 ha-1 through DAP and SSP. Among sulphur levels, upto 40 kg S ha-1 showed significantly higher growth rate and yield characters. The PROM can be a better strategy for the improvement of growth and yield characters.
