SHAMIM The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh to evaluate the influence of propagation of jhau (Casuarina equisetifolia) and wax jambu (Syzygium samarangense) through air layering using different root promoting substances during the period from March, 2022 to June, 2022. The experiment was laid out in Completely Randomized Design (CRD) with three replications. Eight treatments, T 0 : Control (75% Soil + 25% Cow dung); T 1 : 75% of (75% Soil + 25% Cow dung) + 25% Vermicompost; T 2 : 75% Soil + 25% Cow dung + Garlic extract (50 g/L); T 3 : 75% Soil + 25% Cow dung + Aloe vera gel (20 ml/L); T 4 : 75% Soil + 25% Cow dung + IBA @ 50 ppm; T 5 : 75% Soil + 25% Cow dung + Honey (2 table spoon/L); T 6 : 75% Soil + 25% Cow dung + NAA @ 40 ppm and T 7 : 75% Soil + 25% Cowdung + IAA @ 30 ppm were included in the study. Results showed that the significant variations were observed among different parameters. In the case of different treatments performance of jhau, T 1 showed best performance in terms of total number of roots per layer (70.20), rooting percentage (95.55%) and survival percentage after placing in the polybag (90.40%) and the order of rank of study was T 1 > T 4 > T 6 > T 3 > T 2 > T 7 > T 5 > T 0 . On the contrary for wax jambu, T 6 showed best performance in terms of total number of roots per layer (63.60), rooting percentage (97.76%) and survival percentage after placing in the polybag (74.67%) and the order of rank of study was T 6 > T 1 > T 4 > T 5 > T 0 A Thesis Submitted to Department of Entomology, Faculty of Agriculture.

The experiment consists of two factors viz.: factor A: different amount of substrates; B 1 = 250 g, B 2 ii = 500 g, B 3 = 750 g, B 4 = 1250 g, B 6 = 1500 g and factor B: Types of mother culture; T 1 = 1000 g, B 5 = Bamboo stick, T 2 = Sawdust, T 3 = Wheat grain. The experiment was laid out in two factors Completely Randomized Design with six replications. Data were gathered on several growth and yield parameters and it was discovered that the analyzed parameters varied significantly. In case of different substrate amount, yield contributing characters such as maximum number of fruiting body per packet (4.92), maximum single weight of fruiting body (3.18 g), longest length of stalk (2.50 cm), highest diameter of stalk (1.60 cm), diameter of pileus (6.92 cm), thickness of pileus (1.73 cm), biological yield (97.52 g), economic yield (88.24 g), dry yield (61.27 g) was observed from B 4 treatment. In case of mother culture (inocula), maximum number of fruiting body per packet (4.67), weight of individual fruiting body (3.12 g), length of stalk (2.27 cm), diameter of stalk (1.56 cm), thickness of pileus (1.42 cm), highest biological yield (84.74 g), highest economic yield (73.24) and highest dry yield (54.39 g) was recorded from T 2 treatment. In case of combined effect, maximum number of fruiting body (4.82), highest single weight of fruiting body (3.59 g), longest length of stalk (2.77 cm), diameter of stalk (1.83 cm), diameter of pileus (7.25 cm), thickness of pileus (1.72 cm), maximum biological yield (98.20 g), maximum economic yield (88.65 g) and maximum dry yield (62.35 g) was recorded from the combination of B 4 T 2 treatment. Among the treatments B 4 (1000 g) substrate with T 2 (Sawdust) treatment combination exhibited better growth and yield of Reishi mushroom.

This experiment mainly focuses on the growth and yield of BARI onion 3 by using organic fertilizer based on reducing of chemical fertilizer. The experiment consisted of six treatments: NPK (control), Vermicompost (8t/ha), 90% recommended dose of NPK with 400 ml/ha Sea Weed, 80% recommended dose of NPK with 600 ml/ha Sea Weed, 70% recommended dose of NPK with 400 ml/ha Sea Weed and 50% recommended dose of NPK with 1000 ml/ha Sea Weed and was laid out in Randomized Complete Block Design with five replications. For this study, data were calculated on plant height(cm), number of leaves, leaf diameter(cm),leaf length(cm), leaf length(cm) and also after harvesting data were collected on bulb length(cm), bulb diameter(cm), fresh weight of bulb per plant(g), dry weight of bulb per plant(g), yield per plot(g) and yield per ha (t/ha). This study showed the best results for the following parameters were produced by 1000 ml sea weed extract with 50% NPK treatment, the maximum plant height (50.60 cm), maximum number of leaf 9 per plant, maximum leaf diameter of plant (0.78 cm) and yield (16.64 t/ha). On the other hand, in treatment 1 the following parameters were very poor compare to others. It is clearly showed that the better result in various parameters in this experiment was produced by sea weed extract (1000 ml/ha +50%NPK). So, the study showed that the application of biostimulant, sea weed enhances the growth and yield of onion . A Thesis Submitted to Department of Entomology, Faculty of Agriculture.

The experiment consisted of two factors. Factor A: Six different amount of substrates viz., B 1 =250 g, B 2 ii = 500 g, B 3 = 750 g, B 4 = 1250 g, B 6 = 1500 g and Factor B: Three different spawning methods viz., M 1 = Top spawning, M 2 = Thorough spawning and M 3 = Layer spawning. The experiment was laid out in completely randomized design with four replications. Data on different growth and yield parameters were recorded and significant variation was found in different studied parameters. In case of different substrate amount B 5 treatment gave the maximum number of fruiting body per packet (24.02), weight of individual fruiting body (3.22 g), length of pileus (9.15 cm), thickness of pileus (2.75 mm), diameter of pileus (6.92 cm), biological yield (275.40 g), economic yield (259.47 g), dry yield (61.89 g), biological efficiency (64.13%) and benefit cost ratio (3.37). In case of spawning method, the highest mycelium running rate (0.66 cm), number of fruiting body per packet (24.88), weight of individual fruiting body (3.02 g), length of pileus (9.68 cm), thickness of pileus (2.63 mm), diameter of pileus (5.56 cm), biological yield (262.99 g), economic yield (237.46 g), dry yield (56.71 g), biological efficiency (67.76%) and benefit cost ratio (3.62) was recorded from M 3 treatment. In case of combined effects, highest number of fruiting body per packet (24.83), length of pileus (9.74 cm), thickness of pileus (2.87 mm), diameter of pileus (7.22 cm), weight of individual fruiting body (3.39 g), biological yield (277.81 g), economic yield (263.70 g), dry yield (61.98 g), biological efficiency (78.36%) and benefit cost ratio (4.12) was recorded from B 5 M 3 treatment combination. In this experiment, due to the interaction between B 5 substrate amount with M 3 spawning method showed better performance in growth and yield of ear mushroom.
