Sesame (Sesamum indicum L.) is a commercially important oilseed crop, widely cultivated across tropical and subtropical regions for its nutritional and industrial value. The productivity of sesame is frequently constrained by inadequate nutrient supply under field conditions. Foliar nutrition offers a practical and efficient approach to supplement crop nutrient requirements during critical growth stages. A pot experiment was conducted at PGP College of Agricultural Sciences, Namakkal, Tamil Nadu, India, during the Rabi season of 2026, using a Completely Randomized Design (CRD) with seven treatments and three replications. The treatments comprised foliar spray of 2% DAP, 1% Nano Urea, 3% Panchagavya, 10% seaweed extract, 1% micronutrient (MN) mixture, and 0.5% ZnSO₄ + 0.5% Borax applied at 30 and 45 days after sowing (DAS), alongside an unsprayed control. Growth attributes including germination percentage, plant height, leaf length, leaf width, and leaf area index were recorded at 30 DAS (pre-spray), after first foliar spray at 30 DAS, and after second foliar spray at 45 DAS. Results revealed that foliar application of 2% DAP (T₂) consistently recorded the highest germination percentage (85–94%), plant height (22.0–34.5 cm), leaf length (5.0–7.5 cm), leaf width (2.5–3.5 cm), and leaf area index (10.6–12.0) across all observation periods. Treatment T7 (0.5% ZnSO₄ + 0.5% Borax) also demonstrated significantly superior growth responses, particularly at 45 DAS. The control treatment (T₁) recorded the least performance across all growth parameters at every observation stage. The findings underscore the efficacy of foliar-applied phosphorus and micronutrient combinations in augmenting vegetative growth of sesame under pot culture conditions.
