Abstract:
A field experiment was conducted during rabi 2018-19 at Students’ Instructional Farm, C.S. Azad University of Agriculture and Technology, Kanpur, U.P. to find out the “Effect of Phosphorus and Magnesium on growth, yield, nutrients uptake and quality characteristics of Indian mustard with twelve treatment combinations T₁: P₀ Mg₀, T₂: P₀ Mg₁₅, T₃: P₀ Mg₃₀, T₄: P₂₀ Mg₀, T₅: P₂₀ Mg₁₅, T₆: P₂₀ Mg₃₀, T₇: P₄₀ Mg₀, T₈: P₄₀ Mg₁₅, T₉: P₄₀ Mg₃₀, T₁₀: P₆₀ Mg₀, T₁₁: P₆₀ Mg₁₅ and T₁₂: P₆₀ Mg₃₀ in factorial randomised block design with three replications. The result showed highest seed yield of (21.30 q ha^-1) at 60 kg P₂O₅ ha^-1 and (20.38 q ha^-1) at 30 Mg ha^-1 and stover yield of (67.90 q ha^-1) at 60 kg P₂O₅ ha^-1 and (59.54 q ha^-1) at 30 Mg ha^-1. The interaction effect of phosphorus and magnesium on seed yield was 22.30 q ha^-1 and on stover yield was 70.60 q ha^-1. Seed and stover yields increased due to combined effect of phosphorus and magnesium i.e. 66.44 and 69.95 per cent over control, respectively. Oil content, oil yield and protein content increased till P₆₀ and Mg₃₀ when used alone. However, it further increased when phosphorus and magnesium were applied together of Uttar Pradesh.
