The study was carried out employing initial laboratory trial to identify the optimum concentration of seaweed extract (SWE) for seed treatment followed by field experiment at ZARS, GKVK, Bengaluru during Kharif 2024 with ten treatments replicated thrice in RCBD to evaluate best quantity of SWE for foliar application. It was compared with absolute control, recommended dose of fertilizers (RDF) and vegetable special spray. Application of RDF + seed treatment with SWE @ 2000 ppm + foliar spray of SWE @ 2 ml L?¹ at 15 and 45 DAS (T?) recorded significantly higher growth (per plant branch number-12.7, leaf area-590.9 cm²and SPAD value-57.88) yield parameters (per plant pod number-28.8 and pod weight-191.54 g) and higher pod yield (27.53 t ha?¹) followed by T?? (RDF + foliar spray of vegetable special @ 2 g L?¹). The same treatment recorded the higher uptake of primary (N: 159.8 kg ha?¹, P: 58.3 kg ha?¹, K: 118.1 kg ha?¹). Whereas, higher micronutrient uptake was observed in T10 (Fe: 459.2 g ha?¹, Zn: 149.2 g ha?¹, Cu: 96.4 g ha?¹ and Mn: 142.3 g ha?¹).
