Potato farm discipline simulator

Set a yield target, score 10 farm practices for your season, and see which practices are lowering your yield. Yield depends on doing every task on time: sowing date, seed and plant population, fertiliser at the right stage, irrigation on schedule, and control of weeds, pests and disease. Crop nutrition is 1 of these tasks. A task missed at its time can cost yield that extra work later may not recover. The farm discipline simulator shows how each task, and its timing, changes the yield. For example, a crop that needs water every week and misses 2 waterings early in the season does not get that yield back from extra waterings later, even if the season’s total is the same.

Potato · default yield target

What yield are you aiming for?

The default target is 300 maunds per acre: VAN’s assumed yield for the variety Sahiwal White. If your variety yields more or less, type your own number. Then score your season below. The simulator estimates the yield that your scores would give, and shows which practices would add the most yield towards your target.

maunds/acre

Estimated yield from your scores below, which all start at OK (model estimate)

150

maunds/acre

150 maunds per acre below your target

Where the most yield could be gained (model estimates, not trial results)

Seed tuber quality and source is scored OK. Raising it to Best could add up to 30 maunds per acre.

Disease management (late blight and other field disease) is scored OK. Raising it to Best could add up to 27 maunds per acre.

Irrigation management is scored OK. Raising it to Best could add up to 22.5 maunds per acre.

Target 300Estimated 150150 below target

Seed Tuber Quality & Source

Farmer-saved seed but 1st–2nd generation from a known clean or certified source, visually inspected and rogued

Disease Management (late blight and other field disease)

Fungicide applied reactively after visible late blight symptoms; monitoring only moderate

Irrigation Management

Minor delay or unevenness during initiation or bulking, but nothing missed outright

Macronutrient Nutrition (potash and nitrogen timing)

Potash applied at part of the optimum; nitrogen reasonably timed but not split to match peak demand

Insect-Pest Management (aphids and tuber moth)

Insecticide applied only after visible infestation or damage

Hilling / Earthing-Up and Land Preparation

Hilled, but late or with incomplete cover

Micronutrient and Soil Fertility (calcium, zinc, boron)

Micronutrient applied partially or inconsistently

Seed Rate / Plant Spacing

Moderate deviation from the recommended spacing or seed rate

Planting Time

Planted slightly outside the optimal window

Harvest Timing and Post-Harvest Handling

Timing reasonable but curing or storage practice incomplete

This is a pilot model built from VAN’s own agronomy work. It has not yet been checked against a full season’s field results, so use the yield figure as a rough guide to which practices matter most, not as a forecast for your field.
