Effect of Bio-fertilizer and Gibberellic Acid on Growth and Yield of Baby Corn (Zea mays, Poaceae)

The field experiment was conducted during Zaid season 2021-22 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj (U.P). soil the plot sandy loam in texture, nearly neutral reaction (pH 7.2), low organic carbon (0.48%), available N (171.48 kg/ha), P (13.6 kg/ha) K (215.4 kg/ha). treatments consisted three levels Gibberellic acid 50, 100 150 ppm foliar application (20 g 10g per kg litre water) two Bio fertilizer {Azospirillum seed inoculation (10 20 g/kg seed) Azotobacter seed)} respectively Azospirillum + 10 each gibberellic treatment combined. laid out randomized block design with nine were replicated thrice. Results defined those maximum values plant height (185.29 cm), dry weight (90.42 g/plant), number cobs (2.64), cob length (19.76 husk (48.54 g/cob) without (12.51 yield (11.04 t/ ha), (4.15 t/ha) recorded 10g/kg (T9) combination.
