Quality parameters of sunflower (Helianthus annuus L.) seeds and seedlings under various storage duration and seed invigoration

In eastern part of India especially in West Bengal, high humidity and temperature often act as barriers in maintenance of vigour and viability of seeds during storage. With the objective to maintain and improve seed and seedling quality of sunflower through a simple and cheap method, the present experiment was carried out at laboratory of Department of Seed Science and Technology, Institute of Agricultural Science, University of Calcutta, West Bengal, India in 2015.
