Germination Loss
Germination loss is the decline in the proportion of a seed lot capable of sprouting, measured by laboratory test against the minimum standard prescribed for that crop. A lot falling below the standard cannot lawfully be sold as seed regardless of its physical condition, so the loss reduces value without reducing quantity, and it is evidenced by a dated test result tied to the specific lot.
What Is Germination Loss?
Seed is one of the few inventories where the entire physical quantity can remain intact while the value falls to a fraction of cost. What is being sold is the capacity to sprout, and that capacity declines with storage time, moisture and heat without altering the appearance of the bags in any way. Nothing about a visual inspection reveals it.
Because the attribute is invisible, the evidence is a laboratory result rather than an observation. A dated test tied to a specific lot number, read against whatever floor the legislation sets for that particular crop, is what establishes whether the lot may lawfully be sold as seed at all. Failing lots do not become worthless, since they generally retain value as grain or feed, so the write-down is to that recovery value rather than to nil. At a count the practical difficulty is that deterioration concentrates where nobody looks: bags at the base of a stack, against a wall, or below a leak.
Which Sectors Use Germination Loss and Why
The concept is confined to the seed trade and to businesses holding seed as stock.
- Seed production and processing companies, for whom viability is the product attribute being sold.
- Agricultural input distributors and dealers, holding season stock through conditions that determine whether it survives.
- Agri-input retailers, exposed at the point of sale to lots whose viability may have fallen since receipt.
- Contract farming operations supplying seed to growers, where a failed lot has consequences reaching well beyond its value.
- Lenders financing any of these, since a stock statement in this trade can be perfectly accurate on quantity and substantially wrong on value.
- It has no application to grain, pulses or other agricultural commodities held for consumption, where nobody is buying the capacity to grow.
How Germination Loss Works in Practice
- A seed lot is tested on receipt and the result recorded against the lot number, establishing the proportion capable of sprouting at that point.
- The lot is stored under controlled moisture and temperature, with conditions logged, because both drive the rate at which viability falls.
- Testing is repeated periodically through storage and again before the selling season, since the attribute being sold changes while the bags look identical.
- Each result is read against the minimum the legislation sets for that crop. Anything falling under that floor is barred from sale as seed whatever state the bags appear to be in.
- Failed lots are physically segregated, written down to what they will realise as grain or feed rather than to nil, and disposed of through a route that is documented, since seed removed from the books and later sold as seed is a considerably more serious finding than a valuation error.
Germination Loss: A Worked Example
| Lot | Quantity | Germination at intake | At 30 Sept | Saleable as seed |
|---|---|---|---|---|
| Wheat, lot 41 | 180 quintal | 92% | 88% | Yes, above 85% |
| Wheat, lot 47 | 140 quintal | 89% | 82% | No, below standard |
| Gram, lot 52 | 96 quintal | 90% | 86% | Yes, marginal |
| Value reclassified to grain | 140 quintal | - | - | Rs 3,64,000 written down |
A seed processor near Jalgaon tests stored lots before the sowing window.
Lot 47 is physically intact. Nothing has been stolen, spoiled visibly or gone missing, and a count by weight agrees with the records to the quintal. It has nonetheless stopped being seed, because germination has fallen below the standard at which it can be certified and sold as such. It reverts to grain, worth a fraction of seed value, and Rs 3.64 lakh comes off. This is the reason a count alone cannot verify seed stock: quality is a condition of the value, it declines with storage time and humidity, and only a test reveals it.
Common Mistakes With Germination Loss
The attribute being sold is invisible, and the errors follow from forgetting that.
- Assessing lots by appearance, when bags in perfect physical condition can be commercially finished.
- Supporting a write-down with an internal tray test where the amount is material, which is routinely challenged.
- Using a test result that predates the storage period during which the deterioration occurred, so the evidence describes a different lot condition.
- Sampling only from accessible positions, when the loss concentrates at the base of stacks, against walls and below leaks.
- Reducing the carrying figure to zero, when a failed lot usually still fetches grain or feed prices and only the shortfall is the loss.
- Testing after the count rather than before it, which puts the decision ahead of the evidence meant to support it.
- Leaving failed lots among saleable stock, which risks their being sold as seed.
Need Help With Germination Loss?
Understanding the term is the easy half. The harder half arrives when viability has to be tested before a lot can be valued, and it is answered on site rather than on paper. agro-input stock audit sets out how that is done and what has to be ready before anybody travels.
