An experiment was conducted at Rooftop Garden under 2abotech lab, Department of Horticulture, Sher-e-Bangla Agricultural University, Bangladesh during November 2012 to July 2013 to find out growth and yield performance of potted Gerbera against foliar application of different concentration of Gibberelic acid (GA 3). Three varieties viz. V 1 (red), V 2 (brick red), V 3 (pink) and four GA 3 concentrations viz. G 0 : 0 ppm, G 1 : 100 ppm, G 2 : 150ppm, G 3 : 200 ppm were evaluated in the experiment. Maximum number of flower (22.1), flower bud diameter (3.6 cm), peduncle length (29.3 cm), peduncle diameter (1.9 mm) and flower head diameter (8.6 cm) were found from V 2 while G 2 provided maximum number of flower (24.0), longest peduncle (28.3), maximum peduncle diameter (1.7) but G 2 and G 3 both provided maximum flower bud diameter (3.1 cm) and flower head diameter (8.1 cm). V 2 G 2 was found as the best treatment combination.

An experiment was conducted to evaluate the growth and flowering performance of chrysanthemum cultivars. Thirty two chrysanthemum cultivars coded from V1 to V32 were used in the experiment. Plant height, number of branch per plant, leaf area, number of leaf per branch, chlorophyll content, days to flower bud initiation, days to first petal spread, days to final bloom, number of flower bud per plant, number of flower per branch, number of flower per plant, bud diameter at initiation stage, bud diameter at mature stage, flower head diameter, stalk length and flower durability in plant (days to 50% flower senescence) for different cultivars varied significantly. Number of flowers per plant ranged from 4.3 to 194.6, flower head diameters varied from 2.8 to 17.6 cm and stalk lengths were from 4.4 to 20.1 cm. Amongst the chrysanthemum cultivars V15 (BARI chrysanthenum1) was the maximum flower producing cultivar, while V1 produced the largest flowers and flowers from the V21 had the longest shelf-life. These variations might help in classifying chrysanthemum, for pot cultivation and cut flower, based on their flowering quality which will be beneficial for growers.

To find out the response of potted gerbera under different light spectrum wavelengths of solar radiation was carried out. Three gerbera cultivars viz. V 1 (red), V 2 (pink), V 3 (brick red) and seven

The experiment was carried out at the research orchard of Horticulture Research Centre, Regional Agricultural Research Station, Hathazari, Chittagong to determine the influence of organic manure with the recommended inorganic fertilizers on the growth and yield of BARI Malta 1. Six treatments, i. e., consisting of organic manures along with recommended inorganic fertilizers, were used. Results revealed that application of mixed organic manure consisting of 10kg cowdung with 10kg poultry manure or 1 kg mustered oilcake with recommended fertilizers significantly influenced the fruit bearing and yield of fruits and produced 100% and 87% higher yield than only cowdung with recommended inorganic fertilizer and recommended inorganic fertilizers alone. This treatment also showed better plant growth and quality fruit production as indicated by plant height, canopy spread and the highest TSS content (8%) in the harvested fruits.
