    Effect of organic seed coating on quality and storability of sesame (Sesamum indicum L.)
    (CCSHAU, 2019) Gagandeep Singh; Mor, V.S.
    Seed quality plays crucial role in the crop establishment and overall performance of the crop. The availability of viable and vigorous seed at the time of planting is essential to achieve the target of agricultural production. The good quality seed act as a catalyst for recognizing the potential of other inputs. The organic agriculture boost the utility of botanicals products instead of synthetic products for sustainable growth of agriculture. Keeping in view the experiment was carried in Department of Seed Science and Technology, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana to study the effect of organic seed coating on quality and storability of sesame (Sesamum indicum L.). The seeds were treated with botanicals leaf powder @ 10gm/100gm seed and gum used as adhesive @ 2ml/ 100gm of seed. The experiments consists of eleven treatments viz., control, gum, ajwain leaf powder, neem leaf powder, sheesham leaf powder, curry leaf powder, ram tulsi leaf powder, sham tulsi leaf powder, turmeric rhizome powder, woodash, turmeric leaf powder, marua leaf powder on two varieties of sesame i.e, HT 1 and HT 2. The present investigation was carried out in two different experiments to meet out the objectives of research. In the first experiment, both the varieties were treated just after threshing and at an interval of 6, 12 and 18 months of ageing. The six month old seed of both the varieties resulted better performance in seed quality parameters such as germination, speed of germination, seedling length, seedling dry weight, vigor index, emergence index and seedling establishment as compared to freshly treated seed. After 6 months of ageing a continuous declining trend was observed with advancement of storage period. Turmeric rhizome powder showed significant higher values for all the seed quality parameters which was followed by marua leaf powder shesham leaf powder, curry leaf powder and ajwain leaf powder whereas, gum alone gave the negative effect on seed quality in both varieties.
