“…Sirakole that the maximum number of flowers per plant was observed in the plant which was single pinched at 30 DAT (39.34) followed by double pinching at 30 and 45 DAT and no pinching 38.16 & 34.50 respectively. Whereas reported that pinching at 40 DAT gives the maximum number of flowers per plant (62.78) (Sarkar et al, 2018). And the similar result was reported in African marigold cv (Rajbeer et al, 2009;Shrivastava et al, 2005).…”

“…Phule Ganesh, it was reported the maximum number of branches per plant was seen when pinched at 15 DAT than non-pinched (Gnyandev et al, 2014). In another research, it was found that maximum numbers of branches (40.55 branches/plants) were found when pinched at 40 DAT (Sarkar et al, 2018). Research by shows that the maximum number of primary branches and the maximum number of leaves per the plant was produced when pinching at 40 DAT; similar findings were reported in African marigold (Singh et al, 2019;Kumar et al, 2012).…”

Marigold species are famous around the world and grown for its different purpose like beautification, to extract pharmaceuticals products, loose flowers, and cut as well. Among the many species of marigold Tagetes erecta L. is one of the famous species grown in Nepal. Pinching in marigold is a process of increase in flower yield through the diversion of energy through breaking apical dominance in plants. Pinching increases the flower yield (96.78 q/ha) compared to non-pinching (68.78 q/ha) (Rathore et al., 2011) in marigold.

“…xanthophyll content (1.71 mg/g) and total chlorophyll content (2.60 mg/g) were recorded in the treatment T2 (foliar application of GA3 at the rate of 150ppm at 15 days interval) Gibberellic acid is responsible for the favourable changes which influenced the quality (Table 2). These results are in accordance with the findings of Gibberellic acid at 150ppm was recorded growth, flower yield and quality of African marigold by Dweepjyoti Sarkar et al, (2018) [6] and chrysanthemum cv.

This investigations were undertaken to study the effect different growth hormones on growth and yield of African marigold (Tagetes erecta L.) under Coimbatore condition, during March 2019 to October 2019 in two different seasons. The present experiment was laid out in randomized block design with three replications involving foliar application of Gibberellic acid, Cycocel, Brassinosteroids, and silicic acid. The study revealed that foliar application of Gibberellic acid (T2) at the rate of 150ppm showed a significant improvement in morphology and yield and quality parameters in African marigold. The result recorded of maximum plant height (72.52 cm), plant spread (40.89 cm), number of primary branches (9.77), number of flowers per plant (36.52), single flower weight (6.56 g), flower diameter (6.40 cm), flower yield per plant (239.57 g) and highest total carotenoid content (1.32 mg/g) and total xanthophyll content (1.71 mg/g) and total chlorophyll content (2.60 mg/g) were recorded in the treatment T2. whereas the Cycocel (CCC) at the rate of 2000ppm recorded dry matter production (62.93 g per plant), days taken for flower bud appearance (32.61 days), days to first harvest (51.53 days) as compared to control.

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.
