The study has revealed that significantly highest number of flowers per plant (), highest flower diameter ( cm) and highest flower yield per hectare ( q) were observed by application of nitrogen at the rate of 200 kg ha-1 in combination with potassium at the rate of 150 kg ha-1 . Non-significant changes were observed in the available organic carbon content in the soil at the end of the experiment when compared with the application of nutrients before the experimentation. The maximum utility level of the nitrogen and potassium contents by the plant was observed by application of nitrogen and potassium respectively at the rate of 200 and 150 kg ha-1 . |
