Effect of storage containers and seed treatments on seed viability and vigour of greengram (Vigna radiata (L.) Wilczek) cv. CO 6

摘要

One of the most important basic needs for higher agricultural production is quality seed, characterized by high viability and vigour. Maintenance of seed viability and vigour from harvest till the next growing season is of the utmost importance in aseed production programme. Pulses are being cultivated in an area about 226 lakh hectares in India, with the production of 121 lakh M.T. (Karivaradaraaju, 2000). During seed storage, qualitative and quantitative losses upto 8.5 percent have been reportedin India (Anon, 1978). The poor seed quality may also be due to the poor storability which is very often being decided by the internal and external factors. In pulses, the major cause for seed deterioration during storage is bruchid damage. Among different species of bruchids, Callosobruchus maculatus (L.) is considered to be the most destructive in India and causing severe damage to the storage seed to the extend of 93.33 percent in different pulse crop (Parsai et al. 1989).
