Influence of graded levels of nitrogen and potassium on physiological growth parameters and flower yield of garland chrysanthemum (Chrysanthemum coronarium L.)

Abstract

An investigation was carried out at Horticultural College and Research Institute, Venkataramannagudem, West Godavari district of Andhra Pradesh during the year 2015-16 to evaluate the influence of graded levels of nitrogen and potassium on physiological growth parameters and flower yield of garland chrysanthemum. The study has revealed that significantly highest number of leaves per plant (98.00), leaf area per plant (988.00 cm 2), LAI (0.618), LAD (268.04), CGR, AGR, RGR, NAR, Chlorophylla, b and total chlorophyll content were observed by application of nitrogen at the rate of 200 kg ha-1 in combination with potassium at the rate of 150 kg ha-1 along with phosphorus as a common dose to all the treatments at the rate of 100 kg ha-1 during Rabi season. Significantly highest number of flowers per plant (28.00), flower yield per plant (36.00 g) and flower yield per hectare (25.25q) were observed by application of nitrogen at the rate of 200 kg ha-1 in combination with potassium at the rate of 150 kg ha-1 .

Effects of N, P, K Nutrition Levels on the Growth, Flowering Attributes and Functional Components in Chrysanthemum morifolium

“…However, high K 2 SO 4 , as opposed to high nitrogen and phosphorus, enhanced chrysanthemum growth throughout the seedling growth stage (Table 2). Subsequent research validated our findings, showing that chrysanthemum growth rates for plant height, number of primary branches, number of secondary branches, and number of leaves were dramatically accelerated at 200 kg•ha −1 and 150 kg•ha −1 of nitrogen and potassium, respectively [23]. Although potassium is essential for the stability of chlorophyll production in a range of physiological and biochemical processes [8], it also plays an important role in cell division and cellular differentiation in the plant system, causing stunted development when deficient [23].…”

“…Subsequent research validated our findings, showing that chrysanthemum growth rates for plant height, number of primary branches, number of secondary branches, and number of leaves were dramatically accelerated at 200 kg•ha −1 and 150 kg•ha −1 of nitrogen and potassium, respectively [23]. Although potassium is essential for the stability of chlorophyll production in a range of physiological and biochemical processes [8], it also plays an important role in cell division and cellular differentiation in the plant system, causing stunted development when deficient [23]. Hence, we hypothesize that the enhanced plant height, stem diameter, leaf area, and flower diameter at 450 kg•ha −1 potassium sulfate might be due to an increase in cellular differentiation in the chrysanthemum cultivar Boju.…”

“…As a measure of plant biomass accumulation, plant fresh and dry weight are significant indicators of growth vigor [25]. Nitrogen and potassium are significant factors in plant fresh and dry matter accumulation [23,26]. Similarly, the current study revealed that a combined application of 330 kg•ha −1 nitrogen and 169 kg•ha −1 potassium resulted in a considerably higher number of fresh and dry weights in chrysanthemum, but potassium fertilization had the greatest effect (Figure 2).…”

“…Bulawa et al [28] found that potassium doses had a favorable impact on the fresh and dry weights of T. divaricate flower buds, shoots, and roots. Furthermore, the greatest dry weight of the plant was obtained by applying 150 kg•ha −1 potassuim to the Chrysanthemum coronarium cultivar [23]. We propose that an increase in the fresh and dry weight of chrysanthemum plants may be a result of increased vegetative growth.…”

Complete chloroplast genome and phylogenetic analysis of Glebionis coronaria (L.) Cass. ex Spach (Asteraceae)

“…Its stems can be up to 70 cm, while leaves are alternate with long, pinnate split, flowers yellow or white plus some wild Chrysanthemum -like features (Sulas et al 1999 ; Basta et al 2007 ). While its flowers are usually used for flower decoration in social and religious activities, they differ from those ordinary chrysanthemums in several manners (Teja et al 2019 ). Glebionis coronaria has many beneficial effects, including anti-hypercholesterolemia, anti-fungal, anti-hyperglycemia, and anti-aging (Abd-Alla et al 2014 ; Park et al 2019 ).…”
