Spinach is a good source of vitamins riboflavin and calcium and dietary fiber. Now a day plant growth regulators are playing a very important role in increasing yield, growth and improving the quality of crops. The experiment comprised seed treatments of plant growth regulators viz., Gibberllic Acid (GA3), Indole Acetic Acide (IAA), 2,3,5 Trido Benzoic Acid (TIBA) the observations were recorded on characters viz., germination (%), abnormal seedling (%), shoot length (cm), root length (cm), seedling length (cm), seedling dry weight (g) and seedling vigour index-I. The study revealed that the different PGRs effects significant for all parameters. The application growth regulators GA3 @ 50 ppm improved root length (7.37 cm), shoot length (7.91 cm), seedling length (15.28 cm) and seedling vigour index -1(976.81). While, the application of GA3 @ 100 ppm recorded maximum germination (64.72 %) and dry weight (0.570 g). Among varieties, variety Allgreen was found superior for improved root length, shoot length, seedling length and seedling vigour index -1. It may be concluded that germination, seedling growth and vigour of partially aged seed of spinach can be significantly improve with the Application of GA3 @ 50 ppm on variety Allgreen.
