Abstract:
The study was conducted at seed Research and Technology Centre, PJTSAU during 2016 -17 to 2018-19 to know the effect eco-friendly seed treatment on seed storability of Chick pea. Seeds were treated with inorganic insecticides [Emamectin benzoate @ 2 ppm kg^-1 and Delatmethrin @ 1 ppm kg^-1) and botanicals [Azadirachtin 10000 ppm @ 1.5 ml kg^-1, Pongamia pinnata oil @ 5 ml kg^-1, Citronella oil @ 5 ml kg^- and Acorus calamus @ 10 ml kg^-1 seed. Among the different botanical seed treatments, the seed treatment with Acorus calamus has maintained minimum prescribed seed germination (88.11%) up to twelve months of storage, along with the highest seedling vigour index (1348) and lowest seed damage (0.34%). Whereas lower seed germination (61.78%), seedling vigour index (1121) and maximum seed damage (7.71%) was observed in untreated control. Therefore, Acorus calamus @ 10 ml kg^-1 seed has found effective in maintaining the seed quality with minimum seed infestation up to twelve months of storage.
