The present investigation on Effect of organic and inorganic sources of nutrients on flowering of hybrid gerbera (Gerbera jamesonii B.) cv. Shimmer in open field condition was conducted at Biotechnology cum Tissue Culture Centre, OUAT Bhubaneswar during 2015-16 and 2016-17. The aim of the study was to find out suitable organic and inorganic sources of nutrients for cut flower production of gerbera in open field condition. There were eight treatment combinations consisting of 100% recommended dose of fertilizer (RDF), Vermicompost, 75% RDF, PSB, Azospirillum, Azotobacter and foliar spray of macro and micro elements. Application of 75% RDF (15:10:30 g NPK/10 plants) + Vermicompost (25 g/10 plants) + Azospirillum/ Azotobacter (20 g/10 plants) + PSB (20 g/10 plants) + macro and micro element spray recorded earlier flower bud initiation and flowering. The same treatments conducted to maximum length of flower stalk, thickness of flower stalk, flower diameter, number of flowers/plant and bloom life. It can be concluded that reduced dose of chemical fertilizer (75% RDF) along with application of vermicompost and biofertiizer can improve flower yield of gerbera in open field condition.

Background: Application of plant bioregulators at specific concentration modify growth, flowering, flower yield and post harvest quality of flowers. Growth promoters like auxin, gibberellins and cytokinin modify physiological process by accelerating plant growth while growth retardant like cycocel and abscisic acid inhibit plant growth. But in open field cultivation of gerbera, little is known about use of growth regulators on flowering regulation. A good knowledge on use of growth regulators in gerbera is required before going to any recommendations. The current study aimed to standardize suitable bioregulators on flower production in gerbera in open field condition. Methods: The study was carried out in premises of Biotechnology cum Tissue Culture Centre, Odisha University of Agriculture and Technology, Bhubaneswar during 2015-16 and 2016-17. Apart from control eight treatments of growth regulators were used like GA3 @ 100 ppm and 150 ppm, cycocel @ 700 ppm and 800 ppm with or without amino acids as foliar spray. The observation were recorded from 5 randomly selected plant within each replication of treatment for different floral parameters. Result: The result revealed that days taken to flower bud initiation and days taken to flowering was minimum in GA3 @ 100 ppm + amino acid. The stalk length of flower was maximum in treatment GA3 @ 150 ppm + amino acid while largest flower diameter, maximum number of flowers and longest bloom life was observed in treatment with cycocel @ 700 ppm + amino acid. Maximum stalk thickness was found in treatment with cycocel @ 800 ppm + amino acid. The present work will be a complementary contribution to the researchers and gerbera growers in increasing productivity of this flower crops.

The study was conducted to determine the effect of pre harvest spray of micronutrients like boron, zinc and its combination on post harvest quality and vase life of carnation. Post harvest quality of flowers like flower stalk length (65.61 cm) was maximum in the plant treated with zinc (0.3 per cent), and calyx splitting (3.12 per cent) was minimum in the plants treated with boron (0.1 per cent). Flower diameter (6.64 cm) was highest with boron (0.1 per cent) + zinc (0.3 per cent) treatment. Plants without micronutrient treatment produced poor quality flowers. Regarding vase life studies maximum water uptake and minimum transpiration loss from first day to sixteenth day was resulted in the flowers which are obtained from the plant treated with boron (0.1 per cent). The maximum fresh weight of the flower was noticed in combination of boron (0.1 per cent) + zinc (0.3 per cent) from first to sixteenth day. The foliar spray of boron (0.1 per cent) recorded maximum vase life (11.05 days). So the good quality of flowers can be improved by the foliar spray of zinc, calyx splitting can be controlled by boron foliar spray and vase life of the flower can be maintained by foliar spray of boron. It is confirmed that the foliar application of micronutrient is very much helpful for the improvement of post harvest quality and vase life of carnation.

A Field Experiment was conducted during Rabi season 2019-2020 at Experimental field, Department of Horticulture, Naini Agriculture Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.), India. The experiment was Evaluated in a Factorial randomized block design (FRBD) with three replications and 12 treatments. Among the CRF of 6g recorded significantly higher growth parameters followed by CRF of 4g, 2g and control. Spacing of 45cm x 60cm had a considerable influence on the number of leaves and length of leaves. Whereas, plant height was significantly higher with a spacing of 15cm x 30cm at all the growth stages. In flowering parameters, Controlled-release Fertilizers and spacing had a significance influence on the flowering parameters of statice. CRF of 6g per plant obtained notably higher flowering parameters like length of flower stalk and day of flower bud initiation to the day of harvesting whereas, highest delay in flower stalk initiation was observed in Control. The closer spacing of 15cm x 30cm had considerable influence on days required to flower stalk initiation/appearance, length of flower stalk and day of flower bud initiation to the day of harvesting or flowering duration. The higher yield with superior quality of flowers obtained with CRF of 6g with wider spacing of 45cm x 60cm.

Investigations were conducted to study the effect of different polyamines and natural growth substances as a pre harvest foliar spray on greenhouse rose cv. Samurai. The study involved preharvest foliar spraying with polyamines like spermine (10 ppm) and spermidine (10 ppm); natural growth substances like enriched banana pseudostem sap (1 per cent) and cow urine (2 per cent). All the treatments improved the vegetative and flowering characters over control. However, among different treatments, foliar spray of spermine 10 ppm, followed by spermidine 10 ppm were highly significant in influencing all vegetative parameters like plant height (79 cm), number of branches per plant (3.73), stem girth (10.69 mm), number of leaves per plant (91.33), leaf area (14.68 cm2) and leaf chlorophyll content (36.96 mg/g). Further, flowering parameters like flower stalk length (61.24cm), bud length (2.70mm), flower diameter (6.50 cm), number of petals per flower (55.90) and vase life (6.63 days) were significantly maximum in plants sprayed with spermine 10ppm. The treatment of foliar spray with spermine and spermidine almost doubled the flower production and improved the flower quality in tems of bud size and vase life as compared to control.
