The present experiment aimed to find out the effect of paclobutrazol and bunch covering on yield and quality of banana during the period from July 2022 to May 2023. The experiment was consisted of two factors namely Factor A: Different doses of paclobutrazol i.e. P 0 = No paclobutrazol, P 1 =1 gm/L paclobutrazol, P = 2 gm/L and factor B: bunch covering i.e. T 0 = Control (no polythene), T 1 2 = White polythene, T = Blue polythene. The treatments showed significant effect on the yield as well as qualitative traits of banana bunch. Paclobutrazol sprayed plants performed better than non-paclobutrazol sprayed plants. Bunch covering with white polythene plants produced higher yield, Pulp: Peel, moisture content, total soluble solid, titratable acidity, ascorbic acid content. However, blue polythene showed higher amount of sugar content compared to other treatment. Blue and white polythene had no significant effect on color measurement. In terms of interaction effects, white polythene treated with paclobutrazol (1gm/L) produced the highest bunch weight (24.91 kg), pulp: peel (3.57), fibre percentage (4.20) while no polythene treated with no paclobutrazol produced the lowest bunch weight (16.77 kg), pulp: peel (1.89), fibre percentage (2.60). As a result, bunch spraying with paclobutrazol and covering with white polythene are effective for enhancing banana production and quality. 2 Mon, 01 Jun 2026 00:00:00 GMT http://archive.saulibrary.edu.bd/handle/123456789/5695 2026-06-01T00:00:00Z http://archive.saulibrary.edu.bd/handle/123456789/5694 GROWTH AND SEED YIELD OF BROCCOLI AS INFLUENCED BY MICRONUTRIENTS AND ITS APPLICATION METHODS Mostarin, Tahmina Executive Summary The experiment was conducted at the Central Farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during the period from October, 2021 to April, 2022 to investigate growth and seed yield of broccoli as influenced by micronutrients and its application methods. The seeds of BARI broccoli-1 were collected from BARI, Gazipur Dhaka. This experiment was conducted with two factors: Factor-A Micronutrients (Four levels))- (i) F 0 - Zn 74 0 B 0 Mo 0 kg/ha (ii) F 1 - Zn 2.0 B kg/ha (iii) F 2 - Zn 4.0 B 2.0 Mo 1.5 kg/ha and (iv) F 3 -Zn 6.0 B 3.0 Mo 2.0 1.0 Kg/ha Factor-B: Application methods (Three type)– (i) M 1 - Direct soil (ii) M 2 Mo 1.0 - Foliar spray at before flowering (iii) M - Direct soil + Foliar spray at before flowering. There are 12 treatment combinations. The two factors experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Seeds were sown on 01 November and transplanting was done 22 November with distance 60cm X 45cm to be maintained. In case of different levels of micronutrients, maximum number of branches per inflorescence (15.49), number of flower per branches (69.37), number of pods per plant (2204.90) and seed yield per hectare (1.15 t) were observed from F treatment and minimum number of branches per inflorescence (10.26), number of flower per branches (43.14), number of pods per plant (1426.30) and seed yield per hectare (0.65 t) were obtained from F 3 treatment. For application methods, maximum number of branches per inflorescence (14.44), number of flower per branches (63.29), number of pods per branch (31.21) and seed yield per hectare (1.02 t) were observed from M 2 0 treatment and minimum number of branches per inflorescence (11.96), number of flower per branches (48.43), number of pods per branch (28.70) and seed yield per hectare (0.82 t) were observed from M treatment. Due to combined effect, maximum number of branches per inflorescence (16.67), number of flower per branches (77.0), number of pods per plant (2449.30) and seed yield per hectare (1.30 t) were obtained from F 1 treatment combination and the minimum number of branches per inflorescence (9.67), number of flower per branches (37.67), number of pods per plant (1332.80) and seed yield per hectare (0.59 t) were produced from V 0 M 0 treatment combination. So, the F treatment combination appeared to be the best for achieving the higher growth and seed yield of broccoli.

T 1 = S 0 Zn 4 B 2 Kg/ha, T 2 = S 10 Zn = S 20 Zn 4 B 2 Kg/ha, T 4 = S 30 Zn 4 B 2 Kg/ha, T 5 = S 20 Zn 0 B 2 Kg/ha, T 6 = S 20 Zn 2 B Zn 6 B 2 Kg/ha, T 8 = S 20 Zn 4 B 0 Kg/ha,T 9 = S 20 Zn 4 B 1 Kg/ha, T 10 = S 20 Zn 4 B Zn 0 B 0 3 Kg/ha .The experiment was laid out in a Randomized Complete Block Design with 3 replications and there were altogether 33 plots. Application of sulphur, zinc and boron significantly influenced the growth and seed yield of cherry tomato. Among the treatments, the maximum plant height (102.87 cm) at flowering stage, flowers number (568.77/plant), fruits number (77.11/cluster and 499.44/plant), fruit yield (4.58 kg/plant and 27.49kg/plot), seed yield (19.12 g/plant and 114.64 g/plot) and the maximum seed yield (353.83 kg/ha) was found from T 10 and the lowest yield (300.30 kg/ha) was obtained from T treatment. So, the T 10 treatment combination S 20 Zn 4 B 3 11 Kg/ha appeared to be the best for achieving the higher growth and seed yield of cherry tomato.

Jahedur Executive Summary The choice of appropriate growing substrates is an important factor in promoting the optimum growth of crops, like strawberry plants. Mixing of coarser materials with growing substrates at different ratio can improve the physicochemical properties of growing substrates. Selenium is another important mineral for human health. The content of selenium in strawberry can be increased by application of selenium during cultivation. Therefore, an experiment was carried out to evaluate the physicochemical properties of the organic growing substrate mixture and their influence on growth of the plant and yield of strawberry cultivars with application of selenium in hydroponic system. Treatments considered four types of organic growing substrate mixtures (viz., M 1 = 60% rice husk + 30% coconut coir + 10% vermicompost, M = 60% coconut coi r+ 30% khoa + 10% vermicompost, M 3 72 2 = 60% sawdust + 30% khoa + 10% vermicompost, and M = 60% ash + 30% khoa + 10% vermicompost) four levels of selenium (viz., Se = 1.0 mg L -1 Selenium, Se 2 = 2.0 mg L -1 Selenium and Se 3 0 = 3.0 mg L = 0 mg L -1 Selenium) and three varieties (viz.,V 1 : Local Strawberry-1, V 2 :Local Strawberry-2 and V : Local Strawberry-3). Physicochemical properties of growing substrate mixtures and growth, yield, physiological traits, quality of fruits and phytochemicals of strawberry cultivars were measured. The highest pH (7.74) was found in M 4 3 which was not suitable for strawberry production while suitable pH (6.10) was found in M . Water holding capacity, air filled porosity and dry weights of substrate mixtures were higher in M 1 1 and lower in M .The highest plant height (26.16cm), number of fruits per plant (13.08), individual fruit weight (23.85g), fruit length (4.51cm), fruit diameter (4.14cm), fruit volume (22.23cc), yield per plant (321.8g) and ascorbic acid content (70mg/100g FW), TSS (16.14°Brix), total phenolic content (150.77mg/100g FW), total anthocyanin content (8.25mg/100g FW), total flavonoid content (5.97mg/100g FW) and selenium contents in fruits (1.63 mg/100g DW)were found in M 3 1 while the lowest in M . The highest number of fruits per plant (11.96), individual fruit weight (24.93g), fruit length (4.89cm), fruit diameter (4.26cm), fruit volume (20.38cc), yield per plant (305.95g), ascorbic acid content (68.12mg/100g FW), TSS (14.25°Brix) and selenium contents in fruits (3.28 mg/100g DW) were found in Se 3 and quality in Se 2 while the lowest in Se . The highest total phenolic content (139.37mg/100g FW), total anthocyanin content (7.44mg/100g FW) and total flavonoid content (5.0mg/100g FW) were found in Se 2. 0 The highest plant height (23.65cm), number of fruits per plant (14.13), individual fruit weight (25.70g), fruit length (4.61cm), fruit diameter (4.11cm), fruit volume (20.52cc), yield per plant (367.99g) and ascorbic acid content (70.41mg/100g FW), TSS (16.15°Brix), total phenolic content (150.14mg/100g FW), total anthocyanin content (8.63mg/100g FW), total flavonoid content (5.86mg/100g FW) and selenium contents in fruits (1.59mg/100g DW)were found in V 1 while the lowest in V 3 .Therefore, Se formulation can be used for fruit quality and Se 3 2 formulation can be used for growth and yield of strawberry cv.
