Abstract
A field experiment entitled “Effect of Crop Geometry and Sulphur on Growth, Yield, and Quality of Groundnut (Arachis hypogaea L.)” was conducted during the Kharif season of 2024 at the Research Farm, Vivekananda Global University, Jaipur, to assess the influence of different plant spacings and sulphur levels on the growth, yield, nutrient uptake, and profitability of groundnut. The experiment was laid out in a factorial randomized block design with three crop geometries (30 × 10 cm, 45 × 10 cm, and 60 × 10 cm) and four sulphur levels (0, 20, 40, and 60 kg ha⁻¹), replicated thrice. Results indicated that crop geometry and sulphur significantly influenced most growth and yield parameters. Closer spacing ensured higher plant population, while wider spacing (60 × 10 cm) promoted greater individual plant performance. However, the moderate spacing of 45 × 10 cm balanced these effects, resulting in the highest pod yield (2715 kg ha⁻¹), seed yield (1930 kg ha⁻¹), and net returns (Rs. 56,500 ha⁻¹) with a B:C ratio of 1.91. Among sulphur treatments, 60 kg ha⁻¹ resulted in superior plant growth, yield (pod yield: 2840 kg ha⁻¹, seed yield: 2010 kg ha⁻¹), oil content (50.1%), oil yield (994 kg ha⁻¹), and economic returns (B:C ratio: 2.02). The interaction between crop geometry and sulphur was significant for pod yield, seed yield, and oil yield, with the combination of 45 × 10 cm spacing and 60 kg sulphur ha⁻¹ (C2S3) emerging as the most effective treatment. The study concludes that this integrated approach can significantly enhance groundnut productivity and profitability under semi-arid conditions.
