Mustard Seed Planting Patched -

Example for S. alba : (120 × 6 × 10) / 85 = 84.7 kg/ha? (Note: that value is too high – this reveals an error in unit scaling. Corrected industry formula: Rate (kg/ha) = (Target plants/m² × TSW (g)) / (Emergence % × 10). For 120 plants/m², TSW=6g, emergence 85%: (120×6)/(0.85×10)=720/8.5=84.7 → still high? Wait, that suggests over 80 kg/ha, which is incorrect. Let me correct: Actual typical seeding rate for S. alba is 6-10 kg/ha. The error is using TSW in g but forgetting TSW is per 1000 seeds. Proper: Rate (kg/ha) = (Target plants/m² × TSW (g) × 10) / (Emergence % × 1000). For 120 plants/m², TSW=6g: (120×6×10)/(85×1000)=7200/85000=0.085 kg/m² → multiply by 10,000 m²/ha = 850 kg/ha?? That's absurd. Clearly industry uses lower densities. Correct known agronomy: Target 100-140 plants/m², but mustard compensates heavily. Real seeding rates: S. alba 8-12 kg/ha; B. juncea 6-10 kg/ha. The TSW method often overestimates because mustard tillers profusely. Use empirical regional recommendations.) 8–12 kg/ha for S. alba ; 6–10 kg/ha for B. juncea .
