Vegetable Seed Production . Understanding the habit of weeds is also important for non-chemical methods of weed control, such as plowing, surface scuffling, promotion of more beneficial cover crops, and prevention of seed accumulation in fields. Therefore, understanding the molecular aspects of seed dormancy and germination is of a great significance for the improvement of crop yield and quality. Dibbling method of sowing is time-consuming sowing method. Fertilizer will be more or less in a band depending on the width of spread of fertilizer and seed.
