Effect of Bio-Organic and Inorganic Nutrient Sources on Growth and Flower Production of African Marigold

Abstract

African marigold (Tagetes erecta L.) is one of the most important flower crops grown commercially throughout India as a loose flower for worshipping, garland making, and garden display. The productivity and quality of flowers is greatly influenced by the quantity and source of nutrients. At present, these nutrients are primarily supplied through chemical fertilizers. The indiscriminate use and complete reliance on the use of chemical fertilizers has also led to deterioration of soil health, thereby affecting sustainable flower production. Keeping these points in view, a field experiment was conducted on African marigold cv. "Orange Culcuttia"

Effect of different vermicomposts and bioslurry on growth, yield and postharvest quality of statice

“…While no specific literature on statice came up, findings similar to the present study have been reported from various studies involving treatments with organic manures on other crops. These findings are supported by Sharma et al (2017) who when working with marigold (var. Pusa Narangi) reported maximum shelf life and flower vase life from treatments that included application of farm yard manure as organic manure alongside bio fertilizers and NPK in integrated plant nutrient management.…”

“…Similarly, Pansuriya et al (2018) reported significantly enhanced growth and yield parameters in gladiolus from treatment combinations containing bio fertilizers. Sharma et al (2017) also reported increased plant height, number of branches, plant spread, flowering duration and flower yield in African marigold under vermicompost treatments. Abubaker et al (2015) attributed superior plant performance under application of bioslurry to the inhibition of ammonia oxidation and denitrification which potentially benefits crop growth due to reduced losses of soil nitrogen.…”

Effect of GA3 and Biofertilizer on Growth and Yield Parameters of Anthurium (Anthurium andreanum Lindex Ex Andre) cv. Tropical in Soilless Culture

“…Bio-fertilizers increase the absorption of the macro and micro nutrients of plant which influences the overall growth of the plant. Significant increase in spread due to application of Azospirillum, and inorganic fertilizers has been reported earlier in Marigold (Sharma et al, 2015).…”

Marigold: From Mandap to Medicine and from Ornamentation to Remediation

“…Growth and yield of African marigold increases when inorganic fertilizers were supplemented with biofertilizers and organic manures like vermicompost and cow urine. Application of Azospirillum + phosphate-solubilizing bacteria + cow urine (5%) + vermicompost was most effective in increasing vegetative growth and yield attributes[173].Arbuscular mycorrhizal fungi (AMF) constitute a major component of rhi-zosphere microflora in natural ecosystems forming obligate symbiotic associations with many angiosperms, including several medicinal species[174]. AMF enhances the uptake of relatively immobile nutrients by the host plant, particularly P and various micronutrients.…”
