The short answer: choose Mycorrhiza VAM Liquid (50 Ltr, ₹5,800) if you irrigate by drip and farm more than about 15 acres — it costs roughly ₹230–₹360 per acre. Choose the 1 Kg Powder (₹2,499, 6,000 IP/gm) if you farm under 10 acres or want to root-dip and seed-treat — about ₹250 per acre. Both are FCO 1985 compliant. This guide compares infective propagule counts, per-acre economics and application methods, and corrects the incorrect Orgogrowth VAM prices circulating on third-party sites.
