Seeding is used to control pests, nourish the plant, or provide micronutrients to the plant, and improves plant germination by stimulating the plant to increase the production of growth hormones and growth regulators. For this reason, sometimes one or two or more goals can be pursued at the same time. For this reason, sometimes one or two or more goals can be pursued at the same time. Plant nutritional deficiencies that occur after establishment can be compensated by proper seed sowing.
Adding ingredients to seeds to improve crop production began more than 4,000 years ago. Many early methods to reduce fungal stains were targeted at wheat. Products introduced over the past 40 years, including fungicides, insecticides and nematode control products, have been used to protect crops from many pesticides. The concept of seed is the use and application of biological and chemical agents that can basically do the work of control. To improve crop safety, which in turn leads to the establishment of healthy and strong plants, which in turn helps the plant to perform better, increases germination, protects against seasonal diseases and pests, thus improving crop emergence and growth. Seeding also increases plant density, recovery and higher seed productivity. Seeding means soaking the seeds before planting with a compound or compounds that increase seed germination, increase root volume, and better seedling establishment. The term seed is used to refer to the use of a substance that has been inoculated with a pesticide or exposed to a process designed to provide basic nutrition and reduce, control, or repel disease organisms, insects, or other pests. Seeds of corn, peanuts, cotton, wheat, barley, millet, soybeans, pine trees, and plant seeds are usually sown with one or more pesticides and nutrients.
Seeds of corn, peanuts, cotton, wheat, barley, millet, soybeans, pine trees, and plant seeds are usually sown with one or more pesticides and nutrients. These limiting factors include: Physical, chemical and microbial.
physical factors:
Inadequate soil ventilation: Due to the high adhesion of soil particles due to the higher percentage of clay in the soil texture.
High percentage of sand particles: Which reduces the water holding capacity of soil.
Seed germination of plants in saline soil: Seed germination is affected by seed or seed age, fruit ripening, seed hardness and the presence of inhibitors. Most of the seedlings that appear in the salt marsh are very small. Even the establishment of good quality seeds is reduced due to environmental stresses such as salinity, wetting, seed burial, moisture deficiencies, weed competition and insect infestation.
Chemical agents:
Sodium: The presence of exchangeable sodium (free sodium) in the soil causes soil salinity and consequently negative soil osmotic pressure. It also prevents water absorption by seeds and reduces the germination and initial growth of the plant and causes vegetation burning.
Microbial agents:
Existence of useless microorganisms in the soil that by disrupting the secretion of toxins (toxins) cause seed germination and reduce the initial growth of the plant. They also compete with beneficial soil microorganisms for food and space. It should be noted that the increase in the population of harmful microorganisms in the soil is due to physical and chemical limiting factors of the soil, which reduces soil fertility. The above reasons, which have been summarized, have increased the success of germination and early growth of the plant if we avoid the environment in which the seed is placed, which is why seedling has become so important. Sowing with a suitable seedbed causes uniformity of seed germination surface and uniform greening of the field surface. Seed creates strong primary root system and secondary (adsorbent) roots in the plant.
How to choose the right seed?
- The choice of a seedling generally depends on the following conditions:
- The nutritional needs of the plant
- Seed germination vigor and energy
- Seed size (large or small)
- physical characteristics of the soil
- Chemical properties of soil
Purposes of sowing: Seeding is used to control pests, nourish the plant, or provide micronutrients to the plant, and improves plant germination by stimulating the plant to increase the production of growth hormones and growth regulators.
