Sustainable 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.
