The present study was carried out at the Hi-tech farm of Department of Floriculture and Landscape Architecture, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during 2019-20 to find out the most suitable organic mulch material and organic nutrient formulation for enhancing plant growth, yield quantum and quality of cut flowers of carnation cv. ‘Loris’ under protected environment. The experiment was laid out in Completely Randomized Design comprising of 20 treatment combinations of mulch materials (4 levels) and organic formulations (5 levels) replicated thrice. The mulching (M0: without mulch, M1: spent mushroom compost, M2: grass mulch and M3: pine needles) was done after 15 days of transplanting of rooted cuttings and organic formulations were applied after every 20-25 days interval. The data were recorded for two consecutive flower flushes during the course of study. The results revealed that plants mulched with M1 (spent mushroom compost) and treated with organic formulation F2 [i.e. drenching with Consort NPK (1.8 g) + Benefit (7.5 ml in 750 ml of water) at 20-25 days interval and spraying of Bio Nematone + Bio Cure F @ 7.5 ml each in 750 ml of water and Grow Care WS (3.75 g) + Microfood (2.5 ml) + Green Miracle (2.5 ml) + PEPTO (1 ml) in 1 litre of water] recorded maximum plant height (95.47 cm and 97.73 cm), plant spread (18.53 cm and 19.77 cm), number of cut flowers per plant (6.50 & 9.57), duration of flowering (28.77 & 28.97 days), vase life of cut flowers (17.83 & 23.53 days) and minimum days taken to reach harvesting stage (141.00 & 132.33 days) during first and second flush, respectively.
