Abstract:
An experiment was laid out in Randomized Block Design (RBD) at Vegetable Research Farm, RHRS, ACHF, NAU, Navsari, Gujarat during Rabi season, 2019-2020 to study the different bio-fertilizers Azospirillium, PSB and KMB with different fertility levels of NPK on growth and yield of cauliflower. The experiment consist of 10 treatments viz., T₁: 75% RDN + Azospirillium (5 l ha^-1), T₂: 100% RDN + Azospirillium (5 l ha^-1), T₃: 75% RDP + PSB (5 l ha^-1), T₄: 100% RDP + PSB (5 l ha^-1), T₅: 75% RDK + KMB (5 l ha^-1), T₆: 100% RDK + KMB (5 l ha^-1), T₇: 75% RDF + Azospirillium (5 l ha^-1) + PSB (5 l ha^-1) + KMB (5 l ha^-1), T₈: 100% RDF + Azospirillium (5 l ha^-1) + PSB (5 l ha^-1) + KMB (5 l ha^-1), T₉: 100% RDF (200:75:37.5) NPK kg ha^-1 and T₁₀: Azospirillium (5 l ha^-1) + PSB (5 l ha^-1) + KMB (5 l ha^-1). Among different treatments, application of 100% RDF + Azospirillium (5 l ha^-1) + PSB (5 l ha^-1) + KMB (5 l ha^-1) recorded maximum plant height (58.40 cm), stalk length (12.20 cm), number of leaves plant^-1 (19.60), N-S plant spread (63.07 cm), E-W plant spread (66.80 cm), curd diameter (21.77 cm), gross weight of curd (2.19 kg plant^-1), net weight of curd (866.00 g plant^-1), yield plot^-1 (17.32 kg) and total yield (32.07 t ha^-1) as well as minimum days to curd initiation (47.40) and days to marketable curd maturity (63.53).
