Question

Why do cotton is used for germination of gram seeds?

Answer 1

for the first part of germination, all a seed needs is warmth and moisture. Soil and nutrients come later when the seedling starts to develop. Gardeners generally would use a soilless seed-starting mix to germinate seeds, but they can keep it even simpler by using common cotton wool. This medium provides moisture and, as an added bonus, allows gardeners to watch the seeds germinate on top of the pillowy white surface, an exciting project to get kids engaged in the magic of gardening.

Answer 2

if we grow Maize and Gram seeds in wet cotton, after the seeds are sprouted it is easy to separate the cotton wool from the roots of young plants.
