A step by step guide to selecting good quality paddy seed and its importance

In good quality seeds, the development of the root system will be more efficient, which facilitates the effective absorption of nutrients and results in a higher yield.

Good quality seed of improved varieties ensures higher yield.

The seed is the basis of any culture. It must be grown, harvested and processed correctly to obtain the best yield and quality results. Good quality seed leads to lower seeding rate, better emergence (>70%), more uniformity, less replanting and vigorous early growth which helps increase insect and disease resistance and reduce weeds.

In this article, we will discuss the importance of selecting good quality paddy seed and how to select it.

Importance of good quality seed

  • Quality seeds can guarantee the genetic and physical purity of crops.

  • They can give the desired plant population.

  • They have the ability to withstand adverse conditions.

  • Good quality seeds can produce vigorous, fast-growing seedlings and can resist the incidence of pests and diseases to some extent.

  • Good quality seeds can ensure uniform growth and maturity.

  • In good quality seeds, the development of the root system will be more efficient, which facilitates the effective absorption of nutrients and results in a higher yield.

  • Good quality seeds will respond well to the addition of fertilizers and other inputs.

  • Good quality seeds of improved varieties ensure a higher yield of at least 10-12%.

Selection of good quality seeds

Seed selection plays an important role in paddy cultivation. There are a variety of factors to consider when selecting a variety of rice:

  • Adaptability to local conditions

  • High yielding and certified seeds

  • Good grain quality

  • resistance to pests and diseases

  • Maturity or duration of growth

  • Housing resistance

  • Moderate seed dormancy

  • Tolerance to adverse soil conditions

  • drought tolerance

Quality Seed Separation Methods

To separate the good seeds from the bad, soak them in water and the non-viable seeds will float to the surface of the water. These seeds can be easily removed and the leaking seeds can be used for cultivation. By this method, damaged seeds can easily be removed. One of the other methods is used when there is an excess of fleshy kernels in the seed stock. Take some water in a container and drop an egg in it. Keep adding salt slowly until the egg reaches the surface.

When the seeds are thrown into water, good quality seeds will sink. Remove non-viable seeds that float to the surface of the water. Wash selected seeds in good water 2-3 times to remove salt deposits. If this is not done, the germination ability of the seeds will be affected.

seed rate

The seeding rate varies according to the variety to be grown. The seeding rate required for one hectare of land under irrigated conditions is given below:

Short duration variety: 60-70 Kg/ha

Medium duration variety: 40-60 kg/ha

Long-lasting variety: 30-60 kg/ha

Germination test

The germination test is considered the most important quality test to assess the planting value of a seed lot. The test is designed to measure the ability of seeds to produce normal seedlings. The different ways to perform a germination test are listed below:

  • Tie a handful of seeds in a white cloth, soak it in water for 12 hours and keep it in a dark place for 24 hours. Check the germination percentage the next day.

  • Tie the rice straw together to make a mat. Keep the seeds in the center of the mat, then roll it up and tie it. Soak it in water for a minute and transfer the seeds to a straw. After 24 hours, count the seeds that have germinated.

Take a damp burlap sack, fold it up, put the seeds between the two layers and keep the sack in the dark for a day. Check germination the next day.
