If they do sprout, you can calculate the germination rate by dividing sprouted seeds by total seeds planted, and multiplying by 100. For example, if you plant 10 seeds and 3 of them sprout, then your germination rate is 100* (3 / 10), or 30%. Older seeds tend to have a lower germination rate than newer seeds.
How to calculate the germination percentage of seeds?
The equation to calculate germination percentage is: GP = seeds germinated/total seeds x 100 . The germination rate provides an measure of the time course of seed germination. Germination rate is determined by calculating the GP at different time intervals after planting and then plotting these data. Obtain a petri dish and filter paper.
Should you test seed germination rate before planting?
Testing the germination rate (viability) of seeds before planting is a good idea, especially if the seeds are old, or if you collected them yourself. If the seeds don’t germinate well, you won’t waste time sowing and caring for seeds that don’t have much chance of growing. So, how do you test seed germination rate?
What is meant by speed of germination?
Speed of germination expresses the rate of germination in terms of the total number of seeds that germinate in a time interval. Higher values indicate greater and faster germination.
Why do my seeds have a low germination rate?
Older seeds tend to have a lower germination rate than newer seeds. When germinating seeds, you do need to be careful with factors such as soil temperature, moisture, and air circulation. If the soil is too cold (or too warm), then you may get a low germination rate.
What is germination speed?
Speed of germination expresses the rate of germination in terms of the total number of seeds that germinate in a time interval. Higher values indicate greater and faster germination. This is useful for comparisons only when samples or treatments possess similar germinabilities.
How do you calculate seed rate?
Sowing rate (kg/ha) = target plant population (p/m2) x TGW (g) x 100. % germination x % emergence.
What is considered a good germination rate?
It's not necessary to have 100% success with a germination test. Obviously the higher the better, but anything above a 50% success rate for seeds is acceptable – just sow two seeds per station for the best chance of at least one germinating. It would be prudent to replace seeds if germination rates are lower than 50%.
How do you calculate seed per plot?
Solution: Plant population= 10000𝑚𝑚𝑚 0.75𝑚𝑚×0.2𝑚𝑚 =66666.67 Seed rate= 66666.67×250×100×100 90×90×1000×1000 =20.576 kg Amount of seed required for Gap filling= 5 100 ×20.576= 1.028 kg Total seed required for 1 hectare area= 20.576+1.028=21.604≈ 22kg/ha (Ans).
How do you calculate seedlings per acre?
First convert cm to m. 30cm =0.3m, 90cm =0.9.Multiply between plants spacing and the between rows spacing. 0.3m x 0.9m = 0.27 sqm.Divide area of 1 hectare by 0.27sq m. 10000 sq m / 0.27 sq m = 37037.Therefore the Plant population of potatoes per ha is 37037.
How do you calculate germination energy?

Why do plant growers calculate germination rates?
Before attempting to grow a plant, it is important to know the seed germination type because that helps deter- mine the best seed treatments and sowing options for that seed.
How do you tell if a seed will germinate?
Take the seeds and place them in a container of water. Let the seeds sit for 15 minutes. If the seeds sink, they are still viable; if they float, discard, because they probably will not sprout.

Melusi, for differences in germination rate and percentage read the paper of Ranal and Garcia de Santana. 2006. How and why to measure the germination process?.

Dear Dr Melusi Rampart. In my experiment I compared the germination rate among different population of the same species. This was the procedure I followed:
