Effect of Bio-organic and inorganic nutrients on theproduction of African marigold as an integrated approach towards sustainable floriculture
摘要：Marigold（Tagetes erecta L.） is one of the most important flower crop 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 the soil health, thereby affecting sustainable flower production. Keeping these points in view, a field experiment was conducted on African marigold cv. ?Orange Culcuttia‘ at the Horticultural Research Farm, Indira Gandhi Agricultural University, Raipur, Chhattisgarh, India. The experiment was laid out in Randomized Block Design with three replications and twelve treatment combinations comprising of bio-organics（Cow Urine and Vermicompost）, biofertilizers（Azospirillum and Phosphate Solubilizing Bacteria） and NPK fertilizers. Application of Azospirillum + Phosphate Solubilizing Bacteria + 5% Cow Urine + 50% Recommended Dose of ?N‘ through Vermicompost + 50% Recommended Dose of Fertilizer was found to be more effective in increasing the vegetative growth parameters viz., plant height, number of branches, plant spread as well as flower yield parameters like, number of flowers, flower diameter, fresh and dry weight of flower, flower yield, flowering duration, shelf life and also maximum benefit cost ratio. Thus, use of inorganic fertilizers conjointly with bio-fertilizers and organic manures resulted in better vegetative growth and flower yield attributes in marigold.
