Abstract
Freshly harvested wheat cv. Sonalika and sunflowers cv. Morden seeds were treated with dry seed treatments (crude powders of Curcuma longa rhizomes, Azadirachta indica leaves, Vitex negundo, Bacopa monnieri and Spinacia oleracea, or powdered aspirin, aspirin-containing formulation Aspro, vitamin-C containing formulation Celin or calcium hypochlorite) or seeds were given a soaking/drying treatment. After storage for 3 months in cloth bags, seed germination was tested. All seed treatments improved post-storage germination compared with the untreated control in both crops. Germination percentage for wheat and sunflowers was 78 and 73%, respectively in the control and 88-94% and 82-88%, respectively with seed treatments. Seed treatments also improved emergence and grain/seed yields in pot and field experiments.
