Seed quality in relation to seed size and places of storage in bean seeds

The bean seeds (cv. Premier) were size graded with round perforated metal sieves and graded seeds were subjected for seed quality assessment and yield parameters and ungraded bulk seeds served as check. The results revealed the seeds retained in the 20/64”, 18/64” and 16/64” round perforated sieves recorded higher 100 seed weight, germination and higher number of pods, pod weight and seed yield for five plants as compared to the ungraded bulk and 14/64” sieve retained seeds. In another study, the seeds stored at different ecological conditions revealed that the bean seeds can be stored upto 18 months with minimum loss of viability irrespective of the place, seed treatment and containers. The seeds can be stored in aluminium foil pouches with seed treatments for more than 24 months at all the three ecological conditions. The seeds treated and stored in aluminium foil pouches maintained higher viability of more than 80 percent at Thadiyankudisai and Kadaikanal for more than 24 months.
