Healthy seeds and grains are the demanding enterprise of the recent era for the production of high yield in the next season. The seeds must be stored for the maintenance of high-yielding crop. During storage, major losses of seeds are caused by various biological and nonbiological factors. There is a need to examine reasonable factors of these crop losses, which ultimately affect the market value and quality of the seed.
SEED PROCESSING: MANAGEMENT TECHNIQUES - PowerPoint PPT Presentation
The quality of seeds can be maintained by using careful postharvest handling techniques. There is need to establish the well-suited methods to assess the losses during the process and to use the best technique to minimize the loss and to ensure the quality and safety of the crop.
The target is to achieve the high-quality seeds of the national and international standards that could meet the demand of the supplier.
This chapter emphasizes on the aspects and postharvest techniques that are used to maintain seed quality. A comprehensive review of the better, economical, convenient, and productive methods is provided, focused on the needs of developing countries but also with relevance in more industrialized countries. Seed industry survives for the sake of better quality of seeds and postharvest storage techniques.Tafsiir sheekh umal 114 surah offline
It is a seed quality program that seeks the high achievement and gives the quality assurance. Seed quality is one of the most demanding enterprises of present days. The majority of the seeds especially cereals and legumes by small-scale farmers are produced and stored on the farms. The major problem is the damage due to biological factors such as molds, and insects can be alleviated by implicating effective storage techniques [ 1 — 4 ].
There is a need to develop the effective strategies for seed storage that can give the confirmation of better crop yield and reduce the risks of storage losses [ 5 ].
The value of the seeds allows the farmers to produce high-yielding crops from good quality healthy seeds. Seed quality is the measure of the potential to produce desired quality, healthy, and high-yielding crops at low planting rates [ 5 ]. Seed quality can neither be obtained automatically nor by a permanent process. Efforts are being made to produce best quality seeds for the farmers. Any handling or production stage can reduce the quality of the seed.
To alleviate these losses, careful technical management is required for all seed operations [ 6 ]. Seeds when stored in natural environment or ambient temperature respond readily to temperature, available oxygen, and relative humidity. Metabolic activities, age, and longevity of seeds can be manipulating by controlling the humidity temperature and oxygen [ 7 ]. Reduction of seed moisture content up to an appropriate limit is prerequisite for storage as seed could be damaged because of desiccation.
Seeds can be stored for a longer period due to lower level of humidity. Higher moisture content is more affected by higher temperature so seeds need to be stored in cool location.
Oxygen level can be controlled by hermetic storage in a sealed container which reduces the physiological aging of the grains as well as reduces the physical damage due to insects and fungal growth [ 8 ].
For high-quality yield of crops, timely harvesting and drying are necessary. Biologically active seeds deteriorate readily under most of the circumstances due to fungal contamination and attack of insects and other pests.Copy embed code:. Automatically changes to Flash or non-Flash embed.

Seed processing content Seed processing involves cleaning the seed samples of extraneous materials, drying them to optimum moisture levels, testing their germination and packaging them in appropriate containers for conservation and distribution.
Seed cleaning The cost of maintaining an accession in a genebank is high and space is limited. Debris and damaged seeds can spread infection. Therefore, place only good quality viable seeds in storage. Seed cleaning involves removal of debris, low quality, infested or infected seeds and seeds of different species weeds.

Trays containing rolled paper towels placed in an incubator. It can be applied to firm seeds, which have failed to germinate at the end of germination test. Pink and very dark red stains are indicative of dead tissue.
Classify the seeds into three categories depending on staining pattern: completely stained and viable seeds, completely unstained seeds that are nonviable, and partially stained seeds. Vigor tests supplement information about seed quality. Seeds with low vigor take longer time to germinate. Germination is considered to have occurred when the radicle protrudes by 2—4 mm.
For Clean, Smart and Profitable Farming.
Seedling growth test Measurements of seedling growth root and shoot at specific number of days after sowing give an indication of their vigor Annexure 4D. Slow seedling growth shorter roots and shoots indicates low vigor. Membrane integrity The test is based on measuring the concentration of leachates by electrical conductivity Annexure 4D.
Low—vigor seeds generally possess poor membrane structure. When such seeds are soaked in water, greater electrolyte loss occurs, leading to higher conductivity of water. The test is mainly used for grain legumes.
It is important to note that many species eg, legumes have seeds that are impermeable or only slowly permeable to water. This can affect the leaching of electrolytes from seeds in a conductivity test. Curators should ensure that seeds prepared for long-term conservation are free from the seed borne pathogens.
The methods employed to detect the pathogens are referred to as seed health testing methods. By this method, it is possible to detect sclerotia, smut balls, fungal spores and other fructifications such as pycnidia, perithecia, etc. Seed health testing in laboratory using binocular microscope. Profuse seedling growth may make interpretations difficult. This may be overcome by adding 2,4-D sodium salt to provide a 0. Sometimes, bacterial colonies develop on the agar and inhibit fungal growth making identification difficult.
Quality is defined as good vigor, high purity percent, and germination percent. Each part is dependent upon the other. Seed extraction easily fits into these five areas.About us. Watch our corporate movie. The built-in water nozzle system enables a quick cleaning cycle minimizing any residual formation between lots.
Seed drill, type Equipped with two drills. Semi automatic seed extraction machine, type The fruits are manually fed into the hopper. Seed extraction installation, type Seed extraction machine also cyclamen seed extractiontype Berry extraction machine, type Manually the berries are dosed into the hopper content of about 30 liter of the machine. These berries arrive in a chamber in which a perforated basket and beaters are mounted. In the middle of the perforated basket a shaft is mounted with 4 synthetic material beaters, these are simply exchangeable and are optional.
The revolution of the beaters is adjustable in speed. By the rotation of the beaters in the perforated basket, the present seeds have to be squeezed out of the berry. To minimize the damage of the seeds and to speed-up the process, also water will be pumped through the work chamber.
Also the water supply in the chamber can be used for cleaning the chamber. The seeds can't pass by the sieve and are leaving the chamber through an outlet. These outlet is provided with a slide. When these slide is fully open, the seeds will stay a shorter time in the chamber than when these will be closed partly.
The waste product goes, in contrast to the seeds, through the perforated basket and leaves the chamber through an outlet on the bottom. Under these outlet can be mounted a sieving unit as an option to filter waste material out of the liquids which runs out of the outlet.
