 ABSTRACT

India is the largest producer of vegetables from temperate to humid tropics and from sea level to snowline regions. Vegetable play a vital role in the human health and nutritional security of human beings in addition to improve the economy of the farmers. With the rising vegetable consumption within the country, the emphasis laid out to the export of vegetables. Therefore, there is an urgent need to increase the production of vegetables through the use of quality seed. In this context, supply of good quality seed is an important crucial point and it becomes imperative to evolve a strategy to produce quality seeds and make them available in time at a reasonable price to the farming community. Quality seeds can be achieved through better post harvest operations apart from maintaining seed quality by adopting effective principles of seed production. In this regard seed processing is an important segment of seed industry and plays a vital role in improving overall seed quality either for further storage, production or marketing of seeds. Hence an experiment was conducted to study the effect of different seed processing methods on seed quality during 2015-16 and 2016-17. The experiment consisted of eight different treatment combinations of air screen cleaner, specific gravity separator and indent cylinder. The experiment was laid out in Complete Block Design (CBD). The experimental results revealed the significant effect of different seed processing methods. Significantly highest values were recorded for the parameters like seed physical purity (99.58 %), thousand seed weight (4.12 g), seed rejection (18.66 %), seed germination (97.90 %), seedling vigour and less seed recovery (81.34 %) was recorded in combination of all three equipments (P7) followed by combination of P1+P2 (P4) compared to in ungraded (P8).

Key words: Air screen cleaner, Onion, Seed processing, Specific gravity separator
