Abstract:
The experiment entitled “Effect of different levels of NPK on plant growth, flower quality and spike yield of Snapdragon (Antirrhinum majus L.)”, was carried out under Prayagraj agro- climatic condition in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the month of November, 2020 to March, 2021. The experiment was laid out in Randomized Block Design with three replications and twelve different levels of N, P and K. The study revealed that all the characters were significantly affected by the combination of N.P.K. fertilizers. On the basis of present investigation it is concluded that, the application of T₁₁ N:P:K in the ratio of 91:66:91 kg NPK kg/ ha^-1 treatment was found superior in the terms of plant growth, flower quality and spike yield viz., plant height (99.65 cm), number of leaves per plant (474.53), number of branches per plant (36.40),days to 1^st spike emergence (63.07), days to opening of 1^st floret (69.07) days, spike length (23.52 cm), no of florets per spike (27.33), no. of spikes per plant (8.33), days taken for first harvest (107.53), no of spike ha^-1 (9.26) and vase life (days) (7.33) days of snapdragon. Hence, application of T₅ (91:66:91 NPK kg/ha) on snapdragon plants can be recommended for better growth and flowering under Prayagraj agro- climatic conditions.
