EFFECT OF NITROGEN AND PHOSPHORUS LEVELS ON FLOWER YIELD CHARACTERISTICS OF MARIGOLD (Tagetes minuta L.) var. Vanfool
Present study was carried out during Rabi season in the year 2011-12 and 2012-13 at the Main Experimental Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad, (U.P.) with a view to study the effect of Nitrogen and Phosphorus levels on flowering yield characteristics of Marigold. Maximum number of flowers per plant was recorded with the application of 180 kg N/ha followed by 120 kg N /ha and 120 kg P/ha. Minimum number of flowers per plant was observed in the treatment where no fertilizers were given (N0P0). On further study, it was found that the flower yield/plant increased significantly with increased levels of nitrogen application up to 180 kg N /ha and thereafter, decreased gradually with 120 kg N/ha. Due to phosphorus, maximum flower yield per/plant was recorded with the application of 120 kg P/ha followed by 60 kg P/ha. Maximum weight of 100 fresh flowers was recorded with the application of 180 kg N/ha and 120 kg P/ha.
