Effect of planting dates and spacing on growth and flowering of French marigold Sel. FM 786

Abstract

The present study was carried out in an experimental farm in the Department of Floriculture and Landscaping, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during March to December, 2010. The experiment was laid out in split plot design, comprising of eight different planting dates and two spacing, (viz., 30 × 20 cm and 30 × 30 cm) as sub-plot treatment at monthly intervals from, mid-March to October, 2010. Maximum flower size was recorded for April planting date crop, whereas, June planting date gave the best results for plant height and plant spread. However, maximum number of flowers and maximum yield per plant were recorded in March planted crop. Plant height, plant spread flower size and yield per plant were at maximum in a wider spacing S 2 (30 × 30 cm). Maximum number of flowers per plant as well as maximum yield per plant was recorded in March planting at closer spacing S 2 (30 × 20 cm).

Growth and flowering responses of Lisianthus to different plant spacing

“…Maximum SPAD value (47.9, 55.6 and 51.0) was found at 40, 60 and 80 DAT from treatment S3 and minimum (42.4, 49.9 and 46.0) were observed at 40, 60 and 80 DAT in S1 (Figure 04). Effective photochemical quantum yield of photosystem, coefficient of photochemical fluorescence quenching varied with the row and plant spacing, so spacing is conducive to improving the photosynthetic performance of crop population (Pratibha et al, 2018). This is because plant density affects the nutritional state of plants, light interception and distribution of crop canopy.…”

Effect of Crop Geometry and Age of Seedlings on Its Growth, Flower Yield and Quality of Statice (Limonium sinuatum L.) under Prayagraj Agro Climatic Conditions

“…Plant density plays an important role in case of physiological functioning of plant. The planting distance affect the availability of nutrients, water, and light to plant which affect the photosynthetic activities which have ultimate effect on plant growth and yield [7,8]. Thus, plant density at which a crop is planted has an immense role in growth, yield and flowering of crop.…”
