Seed Viability: Using Ragdoll Method


Seed germination testing helps seed dealers and farmers to have a glimpse of how the seed will perform in a field when favorable growing conditions are available.

Moreover, farmers know that they make a good investment when seeds tested germination rate or percentage is high.

Despite, the other laboratory methods used to know seeds’ germination potential, the “Ragdoll Method,” is one common and even cheaper means that Liberian food crop farmers can benefit from.

Materials needed to employ this method are; seeds, thread, the towel of handkerchief size and tight tube, stick or pencil.

Seed Germination Test Process
• Sample selection at random
• Composite (mix the samples selected for composite sample)
• Select 100 full seeds at random to test for germination but also for big seeds (peanut, soybean, corn) count 50 to test for germination.
• Arrange seeds in rows of 10
• Wet the towel and allow free water to drip off, afterward lay the wet towel flat and add seeds.
• Carefully wrap the cloth around a stick, tight tube or pencil. Also, use the thread to tighten the towel/cloth by wrapping the thread from one end to another.
• Submerge ragdoll in water for few seconds
• Place the ragdoll in a safe place to avoid rats and birds damage.
• In every 24 hours, repeat the submerging activity for three to five days
• After 3-5 days check the number of seeds sprouted
• Calculate germination percentage by calculating seeds sprouted by dividing it by total seeds used and multiply the dividend by 100. Germination percentage from 80% upward is considered good for planting.
