Abstract
A field experiment was conducted during the kharif seasons of 2022 and 2023 at the Agronomy Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, to evaluate the effect of potassium, iron, and zinc on the growth, yield, and quality of groundnut. The study comprised 27 treatment combinations involving three levels each of potassium (K₀: 0, K₁: 25, K₂: 50 kg K₂O ha⁻¹), iron (Fe₀: 0, Fe₁: 15, Fe₂: 30 kg Fe ha⁻¹), and zinc (Zn₀: 0, Zn₁: 8, Zn₂: 16 kg Zn ha⁻¹), laid out in a factorial randomized block design with three replications. The pooled results over two years indicated that the application of 50 kg K₂O ha⁻¹ (K₂), 30 kg Fe ha⁻¹ (Fe₂), and 16 kg Zn ha⁻¹ (Zn₂) significantly enhanced growth parameters (such as plant height), yield attributes (including number of pods per plant, pod weight, and 100-kernel weight), and ultimately improved both pod and haulm yield. Based on the findings, it is concluded that for achieving higher productivity of groundnut in loamy sand soils of North Gujarat, apply 50 kg K₂O ha⁻¹, 30 kg FeSO₄•7H₂O ha⁻¹, and 8 kg ZnSO₄•7H₂O ha⁻¹, in conjunction with the recommended dose of fertilizer (RDF) comprising 12.5:25:25 kg N:P₂O₅:S ha⁻¹.
