+4.2% Cotton Yield, +R$1,394/ha Profit

The Problem

Cotton economics live on a knife edge. Input costs keep climbing, and pushing more fertilizer or chemistry through the same field rarely buys proportional yield anymore. Margin gains have to come from how efficiently the crop converts inputs into bolls — not from spending more on the inputs themselves.

That's a physiological problem, not a fertility or pest-protection problem. It calls for a different lever.

The Trial

A 2024/2025 summer trial in Sorriso, Mato Grosso on FM 911GLTP cotton (FiberMax / BASF) tested two foliar Agrarius applications layered onto the existing program. No reduction in fertilizer or pesticide.

• Location: Sorriso, Mato Grosso, Brazil
• Variety: FM 911GLTP — modern medium-cycle commercial cotton
• Season: Summer 2024/2025
• Protocol: 500 mL/ha at V4 (~40 DAE) and again at F1 (early bloom)
• Plot scale: 25 m², replicated
• Comparison: treated vs. standard management

What Happened

More bolls, more lint and seed, more profit — without adding to the input budget.

• Bolls per plant: 11.3 vs. 9.85 control — +9.6%.
• Fiber seed yield: 5,026 kg/ha vs. 4,824 kg/ha control — +4.2% (an extra 202 kg/ha).
• Photosynthetic efficiency: +8% — the plant converts more light into biomass and fiber.
• Net profit: +R$1,394/ha vs. standard management.

Same fertilizer program, same pest management, same hectares — measurably more cotton at harvest.

Why This Matters

A 4.2% yield lift is meaningful in a commodity crop where margin sits behind every kilogram.

• Input efficiency: the same R$/ha of fertilizer and chemistry produced more cotton.
• Direct profit: R$1,394/ha additional net profit on a 25 m² plot scale, projecting cleanly to commercial scale.
• No operational change: the program drops into existing spray windows.
• Compounds across acres: the gain scales linearly with farm size.

For operations watching every R$ of cost, this is the type of input — small per-hectare spend, measurable per-hectare return — that survives the budget review.

How To Use It

Two applications, both in normal cotton spray windows.

• V4 (~40 DAE): early-season, before the bulk of pest sprays.
• F1 (early bloom): at the beginning of flowering.
• Rate: 500 mL/ha per application; 1 L/ha season total.
• Equipment: standard foliar sprayer.
• Tank-mix: compatible with existing foliar nutrition and crop-protection programs.
• Pairing: layer onto the current fertilizer and pest program — the data showed the gain comes from physiological efficiency, not input substitution.
