This study evaluates the impact of organic, inorganic, and biofertilizers on soil characteristics and potato tuber yield in the variety Kufri Ashoka. The experiment was conducted at the Vegetable Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, Uttar Pradesh, using treatments involving different combinations of fertilizers, including recommended doses of inorganic nutrients (RDF), farmyard manure (FYM), vermicompost, Azotobacter, and Phosphobacteria. Key findings demonstrated that RDF treatment (150:100:120 kg N:P₂O₅ ha⁻¹) produced the highest tuber yield (249.2 q ha⁻¹), significantly outperforming all other treatments. However, the organic treatment T4, which included compost, crop residue, biofertilizers, and FYM, also yielded a substantial 237.1 q ha⁻¹, with improvements in soil health attributes like increased organic carbon (3.6 g kg⁻¹) and reduced pH (7.92) and electrical conductivity (0.22 dSm⁻¹). Results indicated that the integration of organic and biofertilizers led to moderate yield gains compared to RDF but significantly enhanced soil properties, contributing to long-term soil health. Organic treatments promoted improved microbial activity and soil structure, essential for sustainable agriculture. This study highlights the effectiveness of integrated nutrient management, where combining organic and biofertilizers with inorganic nutrients can enhance crop yields while maintaining soil fertility and reducing the negative environmental impact associated with exclusive inorganic fertilizer use.
