dc.description.abstract | The present investigation entitled “Off-season pot mum (Dendranthema grandiflora Tzvelev) production through photoperiodic manipulation and pinching” was carried out at Research Farm of Department of Floriculture and Landscape Architecture, Dr. YS Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) for two consecutive years; 2022 and 2023. The experiment was laid out in CRD (Factorial) with three replications. For pot mum production, genotype ‘UHFSChr-56’ was planted at six different times of the year (15th March, 15th April, 15th May, 15th June, 15th July and 15th August) with four pinching treatments (no pinch, single pinch, double pinch and triple pinch) under two photoperiodic conditions (natural photoperiod and controlled photoperiod). In March planting, triple pinching resulted in the production of best quality pots with maximum pot presentability (95.88 and 94.95 during 2022 and 2023, respectively) and benefit-cost ratio (5.34 in controlled photoperiod). In April planting, the best pots were noted in triple pinch with maximum pot presentability (97.57 and 96.50 during 2022 and 2023, respectively) and benefit-cost ratio (5.44 in controlled photoperiod). In case of May planting, the best results of pot presentability (97.56 and 96.68 during 2022 and 2023, respectively) and benefit-cost ratio (4.83 in natural photoperiod) were observed in triple pinch. Further, June planting resulted in maximum pot presentability (97.16 and 96.08 during 2022 and 2023, respectively) and benefit-cost ratio (5.16 in natural photoperiod) when plants were subjected to triple pinch. However, in July planting, double pinched plants gave the best results for pot presentability (95.65 and 94.62 during 2022 and 2023, respectively) and benefit-cost ratio (4.84 in natural photoperiod). In August planting, single pinched plants gave the best result of pot presentability (87.16 and 86.67 during 2022 and 2023, respectively) and benefit-cost ratio (4.59 in natural photoperiod). Further, out of all planting dates, April planting of ‘UHFSChr-56’ subjected to triple pinch and grown under controlled photoperiod produced the best quality offseason pots with maximum benefit-cost ratio (5.44). Hence, off-season flowering pots of ‘UHFSChr-56’ could be successfully produced by staggered planting starting from March to August using different pinching treatments. | |
