Abstract
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.
Highlights
Marigold (Tagetes erecta L.) is one of the most important commercial flowers belong to family Compositae / Asteraceae grown all over the world, which accounts for more than half of the nation in loose flower production (Jyothi et al, 2018)
The maximum numbers of secondary branches were reported when pinched at 20 DAT (Sharma et al, 2006). Another finding reported that the maximum number of secondary branches were found when single pinched at 30 DAT compared to 40 DAT and no pinched in African marigold cv
The findings of suggest that there are no effects of pinching in 50% flowering in marigold but due to the pinching, the emergence of new branches takes time to enter reproductive phase which affects the maximum number of days to take 50% flowering was in pinched plants (54.99 days) while it was minimum in un-pinched plants (50.56 days) (Khan et al, 2018; Sehrawat et al, 2003)
Summary
Marigold (Tagetes erecta L.) is one of the most important commercial flowers belong to family Compositae / Asteraceae grown all over the world, which accounts for more than half of the nation in loose flower production (Jyothi et al, 2018). In most of the flower crops, the flowering and yield is mainly dependent on the number of flowers bearing branches which can be manipulated by checking vertical growth of plants and encouraging side shoot by means of apical bud pinching (Sasikumar et al, 2015). Such side shoot would provide more scope to bear flowers and in turn contribute for higher flower yield (Sunitha et al, 2007).
