Abstract
Flowers are symbol of purity, beauty, peace, love and passion. In India, various traditional flowers have been grown since time immemorial. Floriculture is the increasing sector in international competition. In India, loose flowers were cultivated in an area of 324 thousand hectares with a production of about 1962 thousand MT during 2017-18. The contribution to loose-flower production by Uttar Pradesh is 46.4 thousand MT from an area of 21.2 thousand hectares during 2017-18.Marigold crop is one of the most important commercial flower crops which grown all over the world and in India as well, accounting for more than half of Nation’s loose flower production. Among loose flowers marigold ranks first,its demand is very high during Dashahera and Diwali. Marigold is an effective source of natural dye, obtained from the flower, for the textile industry. The petals of this flower is the chief source of carotenoids, especially lutein, which accounts for 80-90% of total carotenoids. These pigments are effectively used as a food colourant in the food industry. Flowers are also used to intensify the yellow colouration of egg yolk. The area under the cultivation of marigold in India is 66.13 thousand hectare and total production is 603.18 thousand MT (2015-16). It is one of the important flower crops of the eastern U.P. however, no concentrated effort till date has been made to improve the yield of this crop by use of economical dose of nitrogen Keeping these aspects in view, the present investigation was done on African marigold. The supply of nitrogen adequately is accompanying with vigorous vegetative growth and responsible for the profound green colour of leaves. application of nitrogen @150 kg/ha is of great significance for better growth, flower production and yield of seed is manifold average fertility. It, therefore, seems to be logical to recommend a good crop of African marigold cv. PusaNarangiGainda can be taken up in agro-ecological condition of Varanasi region by application of 150 kg/ha nitrogen along with the recommended dose of phosphorus and potash.
