Spach] Anjali Chandel*, Y.C. Gupta and Suman Bhatia Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan 173230, Himachal Pradesh, India *Corresponding author ABSTRACT Two strains of annual chrysanthemum [Glebionis coronaria (L.) Spach] viz. GC- W (White) and GC-Y (Yellow), as part of their proposed INM schedule were K e yw or ds applied with certain organic (Biofertilizers, Jeevamrit) and inorganic fertilizers Annual (NPK) in various combinations. Same observations on various growth and chrysanthemum, flowering and yield parameters were recorded both the strains in two successive Biofertilizers, years. Results revealed that growth parameters such as maximum plant height Phosphate Solubilizing (95.31 cm), plant spread (45.19 cm), flowering parameters such as minimum Bacteria, Cost number of days taken for first flower opening (95.01 days), maximum number of Benefit Ratio flowers per plant (170.50), individual flower weight (2.30 g), duration of flowering (54.97 days) and yield parameters such as maximum flower yield per Article Info plant (490.80 g) were recorded in the plants receiving the treatment of Accepted: 08 January 2020 Azotobacter, Phosphate Solubilizing Bacteria (PSB) and 75% recommended dose 2 Available Online: of fertilizers (20 g N and 10 g P2O5 / m ). Whereas maximum flower size at the 10 February 2020 time of peak flowering (5.91 cm), was found in the plants supplied with Azotobacter, PSB and 50% RDF. The observed cost benefit ratio in both the strains ranged from 1.92 (GC-W) to 2.00 (GC-Y). Introduction coloured flowers with single, double or semi double forms. The flowers assume economic Annual chrysanthemum (Glebionis coronaria importance on account of their varied uses (L.) Spach) is a popular winter season annual. such as in landscaping, cut flower for vase It was formerly known as Chrysanthemum decorations, garland making, hair adornments coronarium L.

It is and for decorations during religious and relatively shorter in duration; photo social functions. insensitive and capable of coming throughout the year as compared to florist Annual chrysanthemum generally prefers well chrysanthemum. It bears yellow or white drained sandy loam soil with coarse texture 577 Int.J.Curr.Microbiol.App.Sci (2020) 9(2): 577-583 and aeration with pH of 5.5 to 6.5. The of nutrients in an integrated manner helps to quality of flowers is greatly influenced by the produce sustainable yields with good quality quantity and sources of nutrients. Application flowers. Very few attempts have been made of 200 kg N and 100 kg P2O5/ha was found to so far to study the efficiency of integrated be optimum for obtaining higher yield of nutrient management in flower crops better quality flowers (Satar et al., 2010). particularly in annual chrysanthemum. Though nitrogen and phosphorus greatly influence the production and quality of Materials and Methods flowers, the fertilizers recommendation is generally very high, which reflects directly on The experiment was conducted at the cost of production. Due to increased Experimental farm of the Department of nutritional requirements of crops over course Floriculture and Landscape Architecture of of time it has become impossible to meet the Dr.Yashwant Singh Parmar University of nutritional requirement of the crops, Horticulture and Forestry, Nauni, Solan (HP) exclusively through the organic farming. from November 2016-17 and at the same time Under these circumstances, integrated soil during subsequent year (2017-18) under open fertility management practices involving field conditions. The experimental area fell judicious combination of organic manures, under the mid hill zone of Himachal Pradesh bio-fertilizers and chemical fertilizers seems with sub-Temperate climate characterized by to be a feasible option for sustained mild summers and cool winters. In the first agriculture on a commercial and profitable year of experiment i.e. 2016-17 average scale. Various studies have been carried out maximum/minimum temperature of previously to work out the effects integrated 22.8˚C/6.8˚C, RH 48 % and rainfall of 38.23 application of biofertilizers and inorganic mm was recorded whereas, in year 2017-18 fertilizers on growth, flowering and yield average maximum/minimum temperature was parameters.
