Abstract

The field investigation was conducted in kharif- 2021 at Agronomy farm, B – Division, Plot No – 5, College of Agriculture, Pune with ten treatments and three replications in RBD. The application of 75% RDF + 1% foliar spray of 19:19:19 at 30 DAT + Azospirillum + PSB & KSB was the significant treatment regarding plant height (69.98 cm), neck thickness (1.68 cm), number of leaves plant-1 (11.40), dry matter plant-1 (26.26 g), days to maturity (142.33), polar and equatorial diameter (6.70 and 6.93 cm), number of scales bulb-1 (11.74), fresh weight bulb-1 (157.57 g), yield (300.21 q ha-1) and quality (57.28%) A grade bulbs. Furthermore, net gain was (17.47, 15.33 and 26.14 N, P and K kg ha-1), microbial count of Azospirillum, PSB and KSB was (39.17, 33.56 cfu and 33.31 cfu x 107 g-1) and maximum B: C ratio (3.35) was recorded.
