Not AvailableSustainable agriculture has become a concern, due to the pressures of the “energy crisis” and issues of “environmental protection”. The use of organic fertilizer made from agricultural waste regenerates natural resources and reduces the consumption of fossil energy as well as phosphorus (P) and potassium (K) deposits. There is scant information available concerning the use of organic fertilizer as the sole source of nutrients in flower production, especially in the cultivation of flowers in a soilless condition. The objective of this study was to develop an organic fertilization management system with recommended dose of chemical fertilizer to replace the chemical fertilization management of the cut flower production cultivated under different agroclimatic condition. Seven fertilization treatments were carried out consisting of recommended dose of fertilizer chemical fertilizers along with FYM (Farm Yard Manure) and three organic fertilizers i.e. Vermicompost, Azospirillum and PSB. The effects of the various fertilizations on different flowers were evaluated based on plant growth, nutrient uptake, and flower quality during the 3-year experimental period. The results show that plants receiving only the recommended dose of chemical fertilizer (100% RDF) along with FYM (2 kg/m2/y) were responsible for reduction the growth and flowering in almost all the flowers, indicating that the requirement of organic N and P or other minerals cannot be substituted only with chemical fertilizer. A nutrient source from reduced RDF (75%) along with organic manure i.e. FYM (2 kg/m2/y) and combination of Vermicompost (300 g/ m2) + Azospirillum (2 g/pl/y) + PSB (2 g/pl/y) for cut flower production gave the superior result in all aspects. As per example in gladiolus, in cv. IIHR-22-1 the plants that received T4 treatment had a significantly increased the plant height (58.5 cm), stalk length (72.7 cm), plant yield (1.021 kg spikes/m2 ) and vase life (7.17 days) compared to other treatment compared to the other treatment. Therefore, it can be concluded that In short, it can be said that by reducing the level of chemical fertilizer and optimizing the dose of different organic fertilizer can improve the yield in ornamental crops and Improve soil health as well.Not Availabl
