A Field experiment was conducted at College of Agriculture, V. C. Farm, Mandya, Southern Dry Zone of Karnataka to study the effect of different fertilizer levels and different spacings on nutrient content of okra. The experiment was laid out in split plot design with 3 replications. The variety used for the experiment was Arka Anamika. Main plot treatments consisted of three fertilizer levels like 125% RDF, 100 RDF and STCR approach with combination of different spacings, 60 cm × 30 cm, 60 cm × 22.5 cm, 60 cm × 22.5 cm, 60 cm × 15 cm, 60 cm × line sowing and 60 cm / 20 cm / 20 cm. Nutrient content in fruit was differed significantly due to varying levels of nutrients. Application of 125% RDF (M1) recorded significantly higher nitrogen, phosphorus and potassium content in fruit (2.69, 0.34 and 2.23% respectively), while, lower nitrogen, phosphorus and potassium content was observed in STCR approach (2.35, 0.26 and 2.04% respectively). Significantly higher content of nitrogen, phosphorus and potassium in fruit (2.95, 0.37and 2.04% respectively) was observed with the spacing 60 × 30 cm, whereas lower nitrogen, phosphorus and potassium content (2.21, 0.24 and 1.86% respectively) in fruit was observed in spacing 60 cm × line sowing. Similar trend was observed in secondary and micronutrients.
