A field experiment was conducted at Instructional farm, College of Agriculture, SKRAU, Bikaner during the rabi season of 2021-22. There were 16 treatment combinations with four nutrient managements (control, 75% RDF, 100% RDF and 125% RDF) and four weed control measures (weed free, pendimethalin @ 0.75 kg ha⁻¹ (PE), Oxyfluorfen at 50 g ha⁻¹ (PoE AT 25 DAS) and weedy check) and were evaluated under factorial randomized design with three replications. The results revealed that among the weed control measures weed-free treatment obtained significantly higher seed yield (1313 kg ha⁻¹), straw yield (3282 kg ha⁻¹) and net return (₹76,783 ha⁻¹). However, pendimethalin @ 0.75 kg ha⁻¹ (PE) achieved the highest B: C ratio (2.97) making it the most economical herbicidal option. Among nutrient management treatments 100% RDF recorded superior growth and yield attributes, seed yield (1131 kg ha⁻¹) and net return (₹68,712 ha⁻¹) with a B:C ratio of 2.78

The study concluded that weed and nutrient management plays a crucial role in enhancing fennel productivity and profitability in arid regions. Season long weed-free conditions recorded the highest yield, while the pre-emergence application of pendimethalin @ 0.75 kg ha⁻¹ proved to be the most economical herbicidal treatment. Among nutrient levels, 100% RDF resulted in significantly higher yield and net return indicating its efficiency in meeting the crop’s nutritional requirements. Therefore, combining 100% RDF with pendimethalin application can be recommended as a viable and cost-effective strategy to maximize yield and economic returns in fennel cultivation
