Effect of planting dates and pinching on growth and flowering in African marigold cv. SIRAKOLE

Abstract

A field experiment on the effect of planting dates and pinching on growth, flowering in African marigold cv. SIRAKOLE was carried out during the period between November, 2007 to June, 2008 with four planting dates and three levels of pinching. November planting resulted in more plant spread (north-south, east-west direction), number of leaves, primary and secondary branches per plant. November planting was found beneficial in improving several floral characters like diameter (5.00 cm), number as well as weight of flowers per plot (843.55, 5422.66 g, respectively) and yield of flower per hectare (20083.92 kg). Shoot pinching at 30 days after planting improved plant spread, number of leaves, as well as weight of flowers per plot (3745.95 g) and yield of flowers per hectare (13873.0 kg). Interaction effect of November planting with single pinching was found beneficial in improving flower yield per hectare (21382.96 kg).

Effect of pinching and spacing on growth, flowering and yield of African marigold (Tagetes erecta L.) under semi-arid conditions of Haryana

“…Maximum plant spread (63.59 cm) was recorded when plants were pinched at 28 DAT, while minimum (63.59 cm) was recorded in unpinched plants. Similar results were also recorded by Maharnor et al (2011) and Mohanty et al (2015) in African marigold. Different levels of spacing had significant effect on increasing plant spread except at S 1 (40 × 40 cm) level followed by S 2 (40 x 30 cm) at 5% level of significance.…”

“…Maximum flower yield per hectare (33.33 t) was recorded in plants pinched at 28 DAT, while minimum flower yield per hectare (32.26 t) was found in un-pinched plants. Similar results were also obtained by Sharma et al (2012), Kour et al (2012) and Mohanty et al (2015) in African marigold. Flower yield per hectare increased significantly with every decrease in spacing at 5% level of significance (Table 1).…”

“…Pinching is done to stimulate early emergence of side branches which ultimately produces more number of flowers with good quality and uniform size. Shoot pinching at 30 DAT improved plant spread, number of leaves, weight of flowers per plot (3745.95 g) and flower yield per hectare (13873.0 kg) (Mohanty et al, 2015). The maximum number of branches/plant (22.99) and number of flowers/plant (34.91) was recorded in double pinching at 60 DAT followed by pinching at 30 DAT (19.28) and (31.97), respectively (Meena et al, 2015).…”

“…meter might be due to more number of plants. These results are in close conformity with the findings of Ravindran et al (1986), Bhati and Chitkara (1987) and Mohanty et al (1993).…”

Studies on Effect of Planting Dates and Varieties on Growth and Quality in Gladiolus (Gladiolus hybridus Hort.) Under Sub-Humid Zone of Rajasthans

“…The results also find support from findings of [18] in gladiolus. Favourable growing condition with mild temperature, high relative humidity and low rate of evaporation prevailing during the crop period might have become favourable for bigger size of flowers in October planting have also been reported by [23] in gladiolus.…”
