Impact of Phosphorus and Sulphur Levels on Growth Parameters of Groundnut (Arachis hypogaea L.)
Year: 2024
Type: article
Abstract: Background: Groundnut, a well-recognized oilseed crop belonging to the Leguminosae family, faces several challenges in India that results in lesser productivity compared to the global average. The principal underlying cause of India’s diminished groundnut production lies in the irregular and inadequate utilization of essential nutrients. Given its status as a leguminous oilseed crop, it exhibits a heightened demand for phosphorus, calcium and sulphur, which often remains unmet, further exacerbating the problem. Methods: In a field experiment, split-plot design was employed to investigate the impact of four phosphorus levels (Control, 40, 50 and 60 kg P2O5 ha-1) and four sulphur levels (Control, 25, 50 and 75 kg S ha-1) on the growth parameters of groundnut. Results: The findings demonstrate that the utilization of phosphorus and sulphur fertilizers yielded significant improvements in various aspects of groundnut growth parameters. These improvements encompassed increased plant height, root length, improved root-to-shoot ratio on a length and weight basis, greater numbers of root nodules per plant and dry weight of root nodules per plant.
