“…Increase in number of branches per plant is due to supply of more plant assimilates towards the side branching after the pinching process. The similar results reported by Meena et al (2015), Nain et al (2017) and Baskaran and Abirami (2017).…”

The present investigation was carried out at Horticulture Demonstration Farm, Department of Horticulture, SGT University, Gurugram (Haryana), India during the year 2020-21 with a view to optimize spacing and pinching time in African marigold cultivar Pusa Narangi Gainda for achieving better growth, flowering and seed yield. Experiment comprises of three levels of spacing (30 x 30 cm, 30 x 45 cm and 30 x 60 cm) and two levels of pinching (no pinching, pinching at 30 DAT (Days After Transplanting) and pinching at 60 DAT) in nine treatment combinations. This experiment was conducted in a split plot design (Factorial) replicated thrice. It was noted that wider spacing (30 x 60 cm) and pinching at 60 DAT had significant effect on plant growth, flowering and seed yield. Wider spacing (30 x 60 cm) recorded maximum number of branches (23.31), diameter of main stem (1.30 cm), number of flowers per plant (40.02), flower diameter (9.58 cm), seed yield per plant (30.03 g), whereas, maximum plant height (49.53 cm) and earliest flowering (59.54 days) was recorded in closer spacing (30 x 30 cm). Similarly, pinching at 60 DAT resulted in maximum number of branches (21.17), diameter of main stem (1.23 cm), number of flowers per plant (73.53), flower diameter (40.14 cm), seed yield per plant (28.93 g), whereas, no pinching recorded maximum plant height (48.64 cm) and earliest flowering (69.79 days). Significant interaction between spacing and pinching recorded maximum flower yield/ per plant (949.00 g), flower yield/ per plot (10.10 kg), seed yield/ per flower (0.844 g) and seed yield/ per plot (367.67 g) with wider spacing and pinching at 60 DAT

“…Pinching is the practice of removing the apical part of a plant. The yield of the flower depends upon the number of branches that bear flowers which can be manipulated by inhibiting the vertical growth and encouraging side shoots of plants with the help of pinching (Baskaran & Abirami, 2017). The side shoots provide more scope to produce a large number of flowers.…”

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.

“…Marigold (Tagetes erecta L) is one of the most widely cultivated commercial flower crops in the world and accounts for over half of the world's loose flower production [1]. Since the harvest takes only the flower (used to extract lutein), a large number of marigold residues were randomly discarded.…”

Enriching the nutritive value of marigold (Tagetes erecta L) crop residues as a ruminant feed by lactic acid bacteria during ensilage

Background Marigold (Tagetes erecta L) accounts for over half of the world’s loose flower production, and marigold crop residue (MCR) are abundantly available and should be used as a forage. In this study, MCR from the last commercial flower pickings was ensilaged with lactic acid bacteria (LAB) and the shift in their volatile organic compounds (VOCs) profiles was monitored. Samples were collected at 6 different times during ensilage (3, 6, 9, 12, 15, 30 days) to determine and quantify the VOCs changes using a solid-phase microextraction (SPME) technique and gas chromatography – mass spectrometry (GC-MS). Results After 30 days, the caryophyllene and piperitone, which account for 14.7 and 12.1% of total VOCs, decreased by 32.9 and 9.6% respectively, alcohols increased from 2.8 to 8.1%, and the acetic acid content increased by 560%. Conclusion We have confirmed LAB can degrade the content of terpenes and enhance the content of alcohols and acids in MCR, which was for the first time on terpene degradation in fodder by ensilage. These results have shed light on our understanding of how to improve fodder odor and to enhance terpene degradation by lactic acid bacteria fermentation.
