The study of effect of nitrogen and potash fertilizers and spacing on production of chrysanthemum flowers and economics

The studies on flower production and economics of Chrysanthemum cultivation were conducted at different levels of nitrogen and potash applications along with plant spacings. A dose of 160 kg/ha nitrogen delayed the emergence of flower than control and 80 kg/ha nitrogen. But the no. of flowers buds produced were more at this dose Similar effect was observed on flower colour break. It was due to more vegetative growth. The 160 kg/ha nitrogen produce longer flower stalk, more heavy flowers than control and 240 kg/ha dose. Flower longivity was also more at 160 kg/ha nitrogen application. Although picking days of flowers were more at higher nitrogen applications. The net returns were also more at 160 kg/ha nitrogen applied plots. Potash produced flower earliest at 180 kg/ha dose. Flower bud appearance, no of flowers, flower yield and flower longivity were more at 120 kg/ha dose of potash including the economic returns. Spacing of 60 x 45 cm between plants and rows delayed the appearance of flowers than closely planted plants but no of flowers, flower field and benefits were more to this spacing.
