A field experiment was conducted to study the effect of integrated nutrient management on marigold cv. Pusa Narangi Gainda at College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, during 2016-17. Results revealed that treatment T7 (75% NPK + FYM + AZO + PSB) was found to be significantly good for both vegetative and floral parameters. It recorded maximum plant height (84.85 cm), maximum number of primary and secondary branches (10.03 and 26.55, respectively), maximum stem girth (4.57 cm), earliest bud initiation and flowering (31.89 days and 46.25 days, respectively) and maximum number of flowers per plant (34.40). Minimum days to 50% flowering (50.51 days), 100% flowering (54.57 days) and maximum flower diameter (4.87 cm) were found in treatment T5 (75% NPK +FYM + PSB). Flowering duration (46.22 days) and shelf life (70.67 hours) was superior with application of treatment T6 (75%NPK+FYM+AZO) whereas treatment T3 (AZO+75%N+100% P&K) reported maximum fresh weight and dry weight (5.73g and 1.50 g, respectively). Application of 75% NPK (75:150:150 kg NPK /ha) in combinations with FYM (10t/ha) and biofertilizers (Azospirillum and PSB @ 5 kg/ha) resulted in highest yield (15.53 t/ha) with maximum net return (Rs. 1,90,794/ha) and highest benefit cost ratio of 2.57.
