A field experiment was conducted to find the effect of pinching and application of nitrogen in marigold. Seedlings of marigold cv Pusa Narangi Gainda were transplanted in 2.4 x 3.0 m plots. There wereeight treatments i.e. single pinching (SP), double pinching (DP), SP + 1% nitrogen. SP + 2% nitrogen, SP + 3% nitrogen, DP + 1 % nitrogen, DP + 2% nitrogen and DP+3% nitrogen. Experiment was laid out in a randomized block design with three replications. Double pinching + 2% nitrogen as foliar application significantly increased number of secondary branches and leaves/plant, Plant spread, plant height, number and weight of flowers/plant, flower yield/m super(2), number and weight of seed/plant and seed yield/m super(2). Single pinching + 3% nitrogen treatment significantly increased number of primary branches/plant, whereas early flowering was recorded with single pinching + 1 % nitrogen treatment. All the treatments failed to exert any striking effect on diameter of flower and 100-seed weight.
