INFLUENCE OF PINCHING ON GROWTH AND YIELD OF SNOWBALL CHRYSANTHEMUM

An experiment was conducted at Horticulture Farm, Department of Horticulture Sher-e-Bangla Agricultural University, Dhaka, from October 2012 to March 2013, to evaluate the influence of pinching on vegetative growth, flower size and number of Snowball Chrysanthemum. Three level of pinching were done viz. P₀, no-pinching; P₁, once pinching and P₂, twice pinching and it was laid out in completely randomized design (CRD) with three replications. Results showed the significant variation among all characteristics. Results also revealed the maximum chlorophyll content (12.8%) and leaf area (36.7 cm2) were obtained from P₂ respectively and the minimum chlorophyll content (11.3%) and leaf area (25.3 cm²) was observed from P₀ respectively. Maximum number of flowers (21.4) was found from P₂ and minimum (9.8) was from P₀. Finally, twice pinching showed the good impact on flowering of chrysanthemum.
