Abstract

 The present investigation was carried out at seed testing Laboratory of the Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology & Science Allahabad, Uttar Pradesh during Rabi 2020-2021. The experiment laid out in a Completely Randomized Design. Jeera seeds (Variety) was subjected to various various pre sowing treatments like GA_3, PEG(6000), Salicylic acid, IAA, mancozeb, thiram, Nacl, Cacl2, Kno3, Curry leaf extract, neem leaf extract, ginger extract at various concentrations along with distilled water control.The laboratory data collected for various parameters germination percentage, root length, shoot length, seedling length, seedling fresh weight, seedling dry weight, seed vigour index I, seed vigour index II.The study revealed that jeera seeds primed with (GA₃ 50 ppm) showed maximum germination percent of  (93.09), root length (7.23cm), shoot length (9.45cm), seedling length (16.68cm), seedling fresh weight (4.51g), seedling dry weight (0.49g), vigour index I (1552.41), vigour index II (45.99) increased. GA₃was found to be the best seed treatment for seedling characteristics of both Jeera seeds followed by (Mancozeb 2g/kg), (Ginger extract 3%).

Key words: Jeera seeds, Salicylic acid, ginger extract, mancozeb, thiram, Curry leaf extract.
