BRBN has strengthened infrastructure facilities for production and distribution of quality seeds. BRBN studies the principles that underlie the physiology of seed development in various crops. The objectives are: (i) to discover general indicators for optimal crop husbandry, (ii) to ensure a high yield and high quality, and (iii) to assess the period when the seed is most vital and ready to be harvested.
This knowledge benefits farmers who produce their own seed, as well as seed growers listed with the BRBN. Our seed quality program comprises a Seed Testing Laboratory, Pre and Post Control Plots, Seed Production Areas or Contract Seed Growers, Field Inspection activities, Seed processing activities/operations, Seed storage, Seed treatment and reconditioning.
1. Seed Testing Laboratory
This tests physical purities, determines moisture content, content, weight and number of weed seeds and other crop seeds, tests for seed germination samples which have been drawn by competent laboratory staff.(i) Physical Purity:
This is to assess by weight the amount of the pure portion in a seed sample. This is important, as it is the pure portion that contains the seed embryo. Other portions in a sample are weed seeds, seeds of other varieties, stones and dust. The other portions of the seeds can be deliberately mixed with the seeds or be there unintentionally.(ii) Moisture Content:
Any seed is required to contain a certain amount of moisture for its embryo to survive and not to germinate before it is required. Excess moisture/water in a seed, makes the seed to germinate before it is required. The assessment of water in seeds is done by the competent staff of seed testing laboratory.(iii) Weed Seeds:
Some weeds are prohibited / restricted in seeds. Our seed testing laboratory therefore assess by weight and number, prohibited and restricted seeds in a seed sample.(iv) Other Variety Seeds:
Our seed testing laboratory assess by weight amount of seeds of other varieties, mixed in a sample. This is important to alert the supplier/seller that she/he is selling seeds of other varieties, a practice which is not acceptable.(v) Inert Matter:
Stones, sand, soil, pieces of broken seeds and chaff are known to be life-less or inert. They can, intentionally/ unintentionally be mixed with seeds. Quality Control Laboratory assesses by weight, such inert matter which is not acceptable in business.
