An experiment was conducted to study the effect of pinching and nitrogen on growth and flowering in marigold cv. Pusa Narangi Gainda at Horticultural nursery, Institute of Agricultural Science, Banaras Hindu University, Varanasi during Rabi season, December 2015 to May 2016. The experiment was planned out in Randomized Block Design with 12 treatments in three replications. The treatments include three levels of pinching i.e. no pinching, single pinching at 40 days after transplanting and double pinching at 40 and 60 days after transplanting with four levels of nitrogen i.e. 0%, 1%, 2% and 3%. Among the treatment, no pinching at 3% N recorded maximum plant height (84.14 cm), fresh weight of flower (4.86 g), dry weight of flower (1.01 g), flower diameter (5.12 cm), length of peduncle (5.38 cm) whereas, leaf area (181.14 cm2) and fresh weight of leaf was found highest in no pinching at2% N (1.11 g). The number of secondary branches per plant (37.40) and flower yield per plant (193.52 g) was maximum in double pinching + 2% N. The number of leaves recorded maximum in double pinching + 1% N (221.07). Treatment with no pinching without N recorded earliest days to bud initiation (51.67 days) and maximum duration of flowering (81.33 days).
