Thousand Seed Weight Calculator:
Enter the values of weight of the sample, W(g) and number of seeds, S to determine the value of Thousand Seed Weight, TSW(g).
Thousand Seed Weight Formula:
The Thousand Seed Weight (TSW) represents the weight of a sample containing exactly one thousand seeds, providing an essential measure in agriculture for evaluating the density and quality of seeds. This metric is particularly useful for seed producers, farmers, and agricultural scientists to assess seed size uniformity and potential yield capacity.
A higher TSW can indicate seeds that may produce more vigorous plants, while a lower TSW might suggest smaller, lighter seeds that may not perform as well under certain conditions. This weight measurement helps in determining seeding rates and calculating the necessary quantity of seeds per unit area, essential for achieving optimal planting density and resource use.
TSW can vary across species and varieties due to genetic and environmental factors affecting seed size and density. The calculation of TSW takes into account the weight of a specific sample of seeds and adjusts it to reflect the weight of exactly one thousand seeds.
This standardization simplifies comparisons across different seed batches, aiding in inventory management and ensuring consistent planting results. The formula uses the total weight of a sample and the number of seeds in the sample to yield the TSW.
Thousand Seed Weight, TSW(g) in grams is calculated as the weight of the sample, W(g) grams, divided by the number of seeds, S, multiplied by 1000.
Thousand Seed Weight, TSW(g) = W(g) / S * 1000
TSW(g) = thousand seed weight in grams, g.
W(g) = weight of the sample in grams, g.
S = number of seeds.
Thousand Seed Weight Calculation of Formula:
1.A sample of seeds has a total weight of 50 grams and contains 200 seeds. Calculate the Thousand Seed Weight.
Given: W(g) = 50g, S = 200seeds.
Thousand Seed Weight, TSW(g) = W(g) / S * 1000
TSW(g) = 50 / 200 * 1000
TSW(g) = 250g.
2.A sample of seeds weighs 120 grams and the Thousand Seed Weight (TSW) is calculated as 300 grams. Find the number of seeds, S, in the sample.
Given: W(g) = 120g, TSW(g) = 300g.
Thousand Seed Weight, TSW(g) = W(g) / S * 1000
S = W(g) * 1000 / TSW(g)
S = 120 * 1000 / 300
S = 400seeds.
