“…Similarly, the highest fresh weight per flower (4.32 g) was recorded at non-pinching while the lowest was recorded at pinching (3.93 g). The minimum fresh weight at pinching might be due to an increased number of flowers at pinching that causes a lesser supply of plant bioregulators and food reserve to developing flower which ultimately decreases the fresh weight of the flower (Nain et al, 2017). Singh et al (2017) was recorded at non-pinching while the lowest diameter of the flower (3.94 cm) was recorded at pinching.…”

“…The side shoots provide more scope to produce a large number of flowers. The pinching practice is done because it stimulates the early emergence of side branches which ultimately produces more flowers with good quality and uniform flower size (Nain et al, 2017). When nitrogen is used at optimum rates and at the appropriate time, nitrogen helps in the optimal growth of plants (Gadagi et al, 2004).…”

“…After pinching a greater number of branches raised and the number of flowers also increased but the diameter of the flower is decreased because the nutrients and other mineral content are used in promoting the vegetative growth due to which flower diameter in non-pinching is more than at pinching (Cicevan et al, 2016). Nain et al (2017) obtained the highest flower diameter at non-pinching while the lowest at pinching on African marigold. Further, the highest yield per plant (237.49 g) and yield per ha (9.89 t/ha) was obtained at pinching while the lowest yield per plant (213.35 g) and yield per ha (8.88 t/ha) was obtained at non-pinching.…”

Proper pinching practice and the optimum rate of nitrogen (N) enhance the production of marigold. An experiment was conducted at a farmer’s field in Gadawa-4, Gangaparaspur, Dang, Nepal from July 2018 to November 2018 to investigate the effects of different rates of nitrogen and pinching on yield and yield attributes of African marigold (cv. Kolkata Local). Two factorial experiment was laid in the Randomized Complete Block Design (RCBD) with three replications. There were eight treatments, consist of four rates of nitrogen (0, 50, 100 and 150 kg/ha) and two levels of pinching (pinching and non-pinching). The maximum plant height (89.70 cm), the diameter of flower (4.29 cm) and the fresh weight per flower (4.32 g) and early days to 50% flowering (61.58) were obtained at non- pinching. The highest number of flowers (60.66), yield per plant (237.49 g) and yield per hectare (9.89 t/ha) were obtained with pinching. The highest plant height (92.20 cm) was recorded at 150 kg/ha of N but the highest yield per plant (238.18 g) and yield per ha (9.91 t/ha) was obtained at 50 kg/ha of nitrogen application. No significant effect was noted on the days to 50% flowering, number of flowers per plant, fresh weight per flower and diameter of flowers by different rates of nitrogen. The interaction of pinching and different rates of nitrogen showed non- significant effect on yield per plant and yield per ha. But, the combination of pinching and nitrogen rates at 50 kg/ha recorded the maximum yield per plant (249.20 g) and yield per ha (10.36 t/ha). Hence it is suggested to use pinching practice with optimum application of nitrogen @ 50 kg/ha to obtain high yield of marigold.

“…Older leaves turned yellow, red and brown, while young leaves had symptoms of chlorosis and turned light yellow (Figure 2). Plant height, plant spread, and the number of primary branches per plant of African marigold increased significantly with the increase in nitrogen level from 0 to 30 g m −2 [7]. A suitable supply of N enhanced plant growth efficiency, thus increasing plant yield and flower quality [8].…”

This chapter explores the literature and research on nitrogen in flowers. An overview of nitrogen deficiency symptoms in some flowers, i.e., Curcuma alismatifolia (ornamental curcuma), Tagetes erecta (marigold), Zinnia violacea (zinnia), and Gomphrena globose (gomphrena) were presented. Additionally, nitrogen uptake, translocation, and application in some flowers, i.e., ornamental curcuma, narcissus, orchids, and rose, were discussed in this chapter. Nitrogen affects the life cycle of flower, including vegetative and reproductive phases. Flower size, stem length, number of flowers per plant, and color were reduced by nitrogen deficiency. Therefore, the optimum level of nitrogen supply in each growth stage is important for flower crop production.

“…Interaction also, was not shown the significant difference with number of flower buds per plant except 9 th WAT (P=0.0442) that shown significant with number of flower buds per plant. Nain et al (2017) stated that the number of buds per plant increased significantly with pinching at 5% level of significance and might be due to the reason that extra energy diverted into the production of more reproductive parts instead of vegetative parts. But present results were not agreed with that statement.…”

An experiment was carried out to determine the effect of pinching practice and different concentrations of Paclobutrazol (PBZ) on the flowering of Henckelia Royal Queen plants.Completely randomized design with eight treatment combinations of pinching or non-pinching and different concentrations of Paclobutrazol (0, 15, 30and 60 ppm) soil drenchwas usedwith eight replicates for each treatment. Pinching was practiced twice at two weeks intervals. Flowering parameters viz. number of flower buds, days taken to flowering, number of flowers, pedicel length, corolla length and corolla width were measured at two weeks intervals from 9thweek after the treatment application. Results disclosed that plants showed better flowering performances (P<0.05) with increasing concentrations of PBZ, but degree of leaf deformation was increased. Therefore, the application of 15 ppm PBZ with pinching showed better to obtain dwarf Henckelia Royal Queen plants with improved flowering quality as commercial potted plants. Bangladesh J. Sci. Ind.
