dc.description.abstractABSTRACT The present investigation entitled, “Evaluation of different genotypes of carnation (Dianthus caryophyllus L.) in response to organic and inorganic fertilization modules” was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P) during 2020-2022 under polyhouse with the objectives to find out the possibility of organic cultivation of carnation and to identify suitable genotype(s) for organic and inorganic cultivation. The experiment comprised of fourteen genotypes of carnation and two treatments: inorganic fertilization module (Recommended Dose of Fertilizers) and organic fertilization module (Jeevamrit @ 20 ml/plant as drenching at 30 days interval). The experiment was laid out in Randomized Block Design (Factorial) with three replications. The results revealed that carnations performed well in both the fertilization modules, the organic fertilization module however performed better in multiple characteristics, including stem thickness (5.75 cm), lesser number of days taken for bud formation (149.14 days), bud width (19.61 mm), number of flowers per plant and per square metre (5.55 cut flowers per plant and 133.20 cut flowers per m2), lesser number of days taken for harvesting of cut stem (179.43 days), longer duration of flowering (72.20 days) and profitability. Even though, quality parameters such as stem length and stem sturdiness were non-significant, yield showed significant results. The organic fertilization module increased the bacterial count at 107 dilution from the initial value of 97.67 cfu g-1 to 122.33 cfu g-1. The actinomycetes count at 102 dilution also increased from the initial value of 37.67 cfu g-1 to 57.67 cfu g-1. The initial fungal count at 102 dilution was 26.33 cfu g-1 which increased to 28.33 cfu g-1. This suggests that organic fertilization module (jeevamrit @ 20 ml/plant as drenching at 30 days interval) can act as an alternative for chemical fertilizers in consideration to the low input cost along with improving soil health and have the potential to contribute to better financial outcomes. It can also be concluded that among the different genotypes tested, ‘Bizet’ performed best under organic fertilization module with highest b:c ratio of 2.38. However, under inorganic fertilization module, ‘Bizet’ and ‘Raggio-de-Sole’ (b:c ratio of 2.02) performed better over the rest of the genotypes.
