Abstract:

Seedlings in a nursery or in seedling trays are closely planted and cannot continue growing well under such conditions due to competition for nutrients and sunlight. So the seedlings need to be moved from the nursery to the main field where there is more food and space to grow.Normally, small-seeded crops are first sown in a nursery to let them establish under close care until they are strong enough to withstand the harsh field conditions. The small-seeded crops have very little food reserves in their seeds which means that they need to get nourishment as soon as they develop roots and as shoots emerge onto the soil surface. The little food incorporated into the nursery bed is never enough to sustain the fast-growing seedling for long
