Abstract/ Executive Summary:

The experiment was conducted at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October, 2008 to March, 2009 in CRD with three replications. Suckers of chrysanthemum were collected from a nursery of Dhaka. Sandy loam soil and cow-dung (1.5 kg/pot, 12 inch size pot) were mixed and pots were filled a few days before transplanting. The experiment considered with and without pinching (P₀; P₁, pinching of plant meant removal of 2.0 - 2.5 cm and without pinching meant non removal of the tip of apical bud). An experiment on pinching (viz. P₀; without pinching and P₁; with pinching) with 3 replications showed the tallest (37.7 cm) and the shortest plant (33.4 cm) without pinching and with pinching, respectively. Maximum number of leaves (30.1) and flowers (58.7) per plant were recorded following pinching (P₁); and minimum number of leaves (26.8) and flowers (37.9) per plant were from without pinching (P₀).

Start Date: 00-10-2008

End Date: 00-03-2009

Program Area: Crop-Soil-Water Management

Commodity: Chrysanthemum

Objectives:

To find out the influence of pinching on growth and yield of chrysanthemum

Methodology:

The experiment was conducted at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during October, 2008 to March, 2009 in CRD with three replications. Suckers of chrysanthemum were collected from a nursery of Dhaka. Sandy loam soil and cow-dung (1.5 kg/pot, 12 inch size pot) were mixed and pots were filled a few days before transplanting. The experiment considered with and without pinching (P₀; P₁, pinching of plant meant removal of 2.0 - 2.5 cm and without pinching meant non removal of the tip of apical bud). Suckers were planted at 7 cm depth on 15 October, 2008 with single plant in each pot. During the early growing stage, powdery mildew and leaf spots were controlled by spraying dithane M-45. Fungicide was sprayed twice at 15 days interval. Aphid was controlled by spraying malathion @ 1.5 ml/l twice at seven days interval. Data were collected on plant height, number of leaves, branches and yield of flower per plant from each pot within the period mentioned above. Data were statistically analyzed using MSTAT program. Mean for all the treatments was calculated and the analysis of variance for each of the characters was performed by F test. Difference between treatments was evaluated by DMRT at the 5% level of significance.

Achievement/Findings:

Pinching leads to development of new branches in addition of increasing number of leaves as well as the increased number of flower buds and finally maximum number of flowers in chrysanthemum. Without pinching terminal bud helps to attained optimum vegetative growth without disruption of normal plant growth of chrysanthemum.
