Abstract:
The present investigation was conducted on silty clay loam soil at Modibaug Garden, College of Horticulture, Pune, during the kharif season of 2019-2020 to study the effect of different nitrogen levels on growth, yield and yield attributes of gaillardia (Gaillardia pulchella L.) cv. MG- 9-1. The experiment was laid in Randomized Block Design with three replications comprising of seven treatments with different levels of nitrogen (0, 50,100,150, 200, 250 and 300 kg N/ha) and phosphorous and potash each at 80 kg /ha The treatment comprising of 200 kg nitrogen, 80 kg of each phosphorous and potassium per hectare was optimum for higher growth characters like plant height (cm), plant spread (cm), number of branches and fresh and dry weight of plant (kg), quality flower parameters like diameter of flower (cm), number of ray florets per flower and vase and storage life of flower (hrs.) and yield parameters like number of flowers per plant, weight of flowers per plant (g), yield of flowers per plant (kg) and yield of flowers per ha (q), which was found at par with 250:80:80 NPK kg/ha. Therefore, based on the present study, it is concluded that for getting good quality flower yield of gaillardia cv. MG 9-1, application of 200 kg nitrogen, 80 Kg of each phosphorous and potassium is recommended.
