Effect of integrated phosphorus management on growth and yield of summer sesame (Sesamum indicum L.)

A field experiment was conducted during summer season of the year 2018. The treatments were 25 kg P₂O₅ ha⁻¹ (100% RDF) (T₁), FYM @ 5 t ha⁻¹ (T₂), Vermicompost @ 2 t ha⁻¹ (T₃), 12.5 kg P₂O₅ ha⁻¹(50% RDF) + PSB @ 5 mL kg⁻¹(seed treatment) (T₄), FYM @ 2.5 t ha⁻¹ + PSB @ 5 mL kg⁻¹ (seed treatment) (T₅), Vermicompost @ 1 t ha⁻¹ + PSB @ 5 mL kg⁻¹ (seed treatment) (T₆), 12.5 kg P₂O₅ ha⁻¹ (50% RDF)+FYM @ 2.5 t ha⁻¹ (T₇), 12.5 kg P₂O₅ ha⁻¹ (50% RDF) + Vermicompost @ 1 t ha⁻¹ (T₈), FYM @ 2.5 t ha⁻¹ + Vermicompost @ 1 t ha⁻¹ (T₉) and FYM @ 2.5 t ha⁻¹ + vermicompost @ 1 t ha⁻¹ + PSB @ 5 mL kg⁻¹ (seed treatment) (T₁₀). Result revealed that among the ten treatments, application of 12.5 kg P₂O₅ ha⁻¹ + vermicompost @ 1 t ha⁻¹ to sesame significantly increased the growth, yield attributes and seed yield (881 kg ha⁻¹) over rest of the treatments but remained at par with application 12.5 kg P₂O₅ ha⁻¹ + FYM @ 1 t ha⁻¹. The highest net realization (Rs. 43932 ha⁻¹) was also recorded with 12.5 kg P₂O₅ ha⁻¹ + vermicompost @ 1 t ha⁻¹ followed by 12.5 kg P₂O₅ ha⁻¹ + FYM @ 2.5 t ha⁻¹.
