Depth of Sowing varies from seed to seed or crop to crop. For example Wheat seed require shallow depth to sow and Cotton seed or maize can sow at greater depth as compared to wheat.
basically Seed Size directly or indirectly involved.
for its germination a seed require reserve food which is stored in the form of Endosperm tissue..when a seed starts its germination it utilize this reserve food.
if a seed is small in size (as in case of wheat) it ultimately has little quantity of this stored food so if we'll sow wheat seed to a greater depth it can not germinate as it would have been utilize all food before emergence of seedling.
and vice versa for large size seeds..
so we conclude that EMERGENCE of SEEDLINGS is directly or indirectly EFFECTED by depth of sowing...
Yes, a general "rule of thumb" for planting seed is that it should be planted toa depth of double the diameter of the seed itself.
Seeds that are very small (such as Begonia - 80,000 seeds per 1 gram!!!) obviously cannot be covered. Very large seeds (such as coconut, cycas and various nuts) are normally planted half-in-half-out of the soil, so that the seed contacts the soil and can absorb water, but is not covered entirely.
Seed which is covered too deeply will experience problems germinating properly, and the cotyledons may not make it to the surface before their food supply runs out, additionally they will be stressed and weak if they do make the surface and are then prone to fungal and insect attacks (in their weakened state)
Some seeds are light sensitive, meaning that they should either be covered or left uncovered for optimal germination.
In my class we are growing many types of plants. From this I know, that it mainly depends on the seeds you are growing. For example, guardillia need to be covered 1/2 inch layer of soil. And some plants need to be planted approximately a foot into soil. But I am growing carrots and accidentally dug them three inches deeper than I should have. Yet, they are growing very well and are about the best plants in our class (besides for some lettuces boys are growing) Keep trying your plants will grow...
Assuming that the seeds are planted indoors using a cup or a container of some sort, you will probably have a very low success rate. Reason for this is that the smaller the seed the less energy it has to reach the surface. Nonetheless, soil should only stay moist and covered, spray when top is drying with a bottle of water, and warm to germinate. If the soil is too wet, make sure there is holes in the bottom and let air dry for a day before covering.
If a seed is buried too deeply within the soil, the seed can be oxygen starved. Some seeds have impermeable seed coats that prevent oxygen from entering the seed, causing a type of physical dormancy which is broken when the seed coat is worn away enough to allow gas exchange and water uptake from the environment.
it will not get enough oxygen, water for it to grow properly
Seeds do not always germinate. Some fail because they were never fertilized, but others fail because the growing conditions aren't right. The climate may be too hot or too cold, or conditions may be too dry. They may also fail to germinate if they have been infected with mold or disease.
Very few seeds germinate successfully underwater because the growing cells of the sprouting seed eventually take in too much water, and burst, thus killing the developing plant.
1. If you plant a seed too deep, it will not get enough sunlight to germinate.If you plant a seed to shallow, it won't have enough soil cover to support the germinating top growth.The rule of thumb on planting seed is plant three times the depth of the size of the seed. If you have seeds that are very tiny, just the barest covering of soil is enough. For larger seeds, the depth varies with the size of the seed.2. It is necessary to sow seeds at an appropriate depth because it ensures the proper and timely germination of the seed. The seed sown at more depth will not be able to germinate on time and the leafs will not appear on the surface on time. This is because it has to cross the layer of soil to come or appear on the surface.Similarly the seeds are not sown superficially on the ground because they can be eaten by the birds or can be easily carried away by wind.
Yes, But I have dusted the seeds with guano-gro prior to planting and have gotten seeds that would normally germinate in 7-10 days to germinate in the ground in less than 30 hours. Downside - is when I tried to beat the 30 hour germination - no seed could be found. So too much of a good thing is not always good.
No most seeds need tempuratures about 60 degrees to germinate.
Seed germination is significantly affected by temperature. When it is cool, seeds are slower to germinate than when it is warm. If conditions are too cool or too hot, seeds won't germinate at all.

John really wanted a vegetable garden. Unfortunately, his new plants died because he had sown the seeds too early in the spring.
It is because the seed might be too old or you overfed the plant and that is why it did not germinate

Insufficient sunlight or water. Some plant seeds will not germinate if the temperature is too cold.

If they were able to grow, then they obviously weren't planted too deep. Most sunflowers can be planted up to six inches deep and still germinate, though it will take longer to make it to the surface.

no but if it produced some seeds they might germinate
