Abstract:
An experiment conducted in the field at the Floriculture Research Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, for three years (2014-15, 2015-16, and 2016-17) to understand how the chrysanthemum 'Ratlam Selection' plant responds to different levels of nitrogen and phosphorus. The experiment was set up in Randomized Block Design with Factorial Concept (RBD). There were nine different combinations with factors of nitrogen and phosphorus with three replication up to three years and combined the data to make results more accurate and to get a better overall picture. For each factor, three different levels were set up. For nitrogen, it was 100, 125, and 150 kg/ha. For phosphorus, it was 50, 75, and 100 kg/ha. After combining the data from all three years, treatment of nitrogen and phosphorus (N₃P₃), resulted significantly maximum weight of 10 flowers, flowers per plant, flower yield per plant, whereas maximum flower yield per plot and per hectare was recorded in N₃P₃ which was found at par with N₃P₂ and N₂P₃. It is observed that using 150 kg/ha of nitrogen and 100 kg/ha of phosphorus (N₃P₃) recorded most economically viable treatment for chrysanthemum production with maximum B:C ratio (1.78).
