CLYBIO CONCENTRATION ON GROWTH AND YIELD OF CABBAGE UNDER DIFFERENT COLORED SHADE NETS BARI, BENJIR HOSNE JAHAN The experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate the growth and yield of cabbage as influenced by two different factors such as factor-A: Colored shade nets viz. without a net (N 0 ), white net (N W ), pink net (N P ), and blue net (N B ), and factor B: Clybio concentration viz. no Clybio application (C 0 ), Clybio concentration at 1000-fold (C 1000 ), and Clybio concentration at 500-fold (C 500 ). The experiment was set up in Split Plot Design with three replications. Data on different growth, physiological and yield parameters were taken in which all the treatments showed significant variations. The use of white shade nets (Nw) provided with better head length (16.0 cm), head diameter (55.7cm), single head weight (1.1 kg), and yield of 45.8 t/ha in comparison to other nets or no net use. Alongside, the sole application of Clybio to cabbage as a 1000-fold liquid solution (C 1000 ) resulted in maximum single head weight (0.8 kg), and yield of 33.3 t/ha while the maximum head length (14.8 cm) was from 500-fold Clybio solution (C 500 ), and head diameter was statistically insignificant between C 1000 . Maximum yield per hectare (62.5 t) was found from N W C 1000 and minimum (20.8 t) was from N 0 C 0 . In consideration to the overall performances, white shade net (N W ) along with the application of 1000-fold Clybio solution (C 1000 ) has the potential for better cabbage production.

INFLUENCE OF PLANT GROWTH REGULATORS ON ROOTING AND SURVIVAL OF STEM CUTTINGS OF CHINA ROSE AND BOUGAINVILLEA NAYEM, MD. GULAM KIBRIA The experiment was conducted at the Germplasm center of Horticulture farm of Sher-eBangla Agricultural University (SAU), Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh to evaluate the influence of plant growth regulators on rooting and survival of stem cuttings of china rose and bougainvillea during the period from June 2021 to March 2022. The duration of the experiment was 5 ii th June to,2021 to 5 th September,2021 in rainy season and 15 th December, 2021 to 15 th March, 2022 in winter season. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Three treatments, viz. G 0 = Control (treated with water), G 1 = Equally mixed Indole Butyric Acid (IBA) @125ppm and Naphthalene Acetic Acid (NAA) @ 125 ppm, G 2 = Equally mixed Indole Butyric Acid (IBA) @250 ppm and Naphthalene Acetic Acid (NAA) @250 ppm were included in this study. In the case of different treatments performance, G 2 showed best performance in terms of days to shoot initiation, number of roots per cutting, length of roots (cm), rooting percentage, shooting percentage, number of shoots per cutting, number of branches, shoot Length (cm), number of leaves, sprouting percentage and survival percentage of China rose and Bougainvillea cuttings. G 2 showed best performance in bougainvillea in terms of rooting percentage in winter season 71.26% and in rainy season 86.74% and survival percentage in winter season 76.67% and in rainy season 85.20%. G 2 showed best performance in china rose in terms of rooting percentage in winter season 74.77% and in rainy season 89.50% and survival percentage in winter season 73.33% and in rainy season 92.36%. In comparison to rainy and winter season, plant growth regulators on rooting and survival of china rose and bougainvillea has found superior result in rainy season. Cuttings also established in winter with the help of plant growth regulators. From the study, it may be concluded that treatment G 2 has more efficacy among different treatments for the influence of plant growth regulators on rooting and survival of stem cuttings of china rose and bougainvillea which was followed by G 1 A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE (MS) IN HORTICULTURE

EFFECT OF MULCH MATERIALS AND FOLIAR APPLICATION OF MICRONUTRIENTS ON THE GROWTH AND YIELD OF SWEET PEPPER UNDER NET HOUSE AKTER, MST. SHAPLA The experiment was carried out at the “Horticulture Farm” of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during November 2020 to April 2021 to study the effect of different mulch materials and foliar application of micronutrients on growth and yield of sweet pepper under net house. The experiment consisted of two factors. Factor A: Three mulch materials viz., M 0 ii - No mulch (control), M 2 - Black polyethylene mulch and M 2 - Rice straw mulch and Factor B: Three foliar application of micronutrients viz., N 0 - control (No micronutrients), N 1 - Zn @0.6% as ZnSO 4 - B @0.6% as H 3 BO 3 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on growth, yield components, yield and quality of sweet pepper and significant variation was observed for most of the studied characters. Under this investigation, it was revealed that the highest fruit yield (63.00 t/ha) with net return (Tk. 1,458,860) and benefit cost ratio (BCR) was obtained (4.67) from M 2 N 2 (Rice straw mulch + B @0.6% as H 3 ) treatment combination. On the other hand, the lowest fruit yield (24.50 t/ha) with net return (Tk. 377,364) and benefit cost ratio (BCR) was obtained (2.05) from M 0 (control) treatment combination. So, economic analysis revealed that the M 2 treatment combination appeared to be best for achieving the higher growth, fruit yield and economic benefit of sweet pepper.

INDOOR PERFORMANCE OF PEPPERMINT (Mentha piperita L.) IN RESPONSE TO VERMICOMPOST AND LIGHT QUALITY BARMAN, BHRIGU RAM The present experiment was conducted at the “Horticultural Biotechnology and Stress Management Lab” of Dr M A Wazed Miah Research Center, Sher-e-Bangla Agricultural University, Dhaka during the period from November 2019 to March 2020 to evaluate the indoor performance of peppermint in response to vermicompost and light quality. The experiment consisted of two factors: Factor A: Vermicompost (4 levels) as V0 = 90 % cocopeat + 10 % broken bricks (Control)/pot, V1 = 30 % vermicompost + 60 % cocopeat + 10 % broken bricks/pot, V2 = 45 % vermicompost + 45 % cocopeat + 10 % broken bricks/pot, V3 = 60 % vermicompost + 30 % cocopeat + 10 % broken bricks/pot; and Factor B: Light quality (Monochromatic LED lights) as L1 = White light, L2 = Blue light, L3 = Red light, L4 = Combined red and blue light. The two factor experiment was laid out in Completely Randomized Design (CRD) with three replications. Vermicompost and light quality significantly influenced different growth and yield parameters of mint. In case of vermicompost, the highest fresh weight per plant (13.95 g) was found from V2 and the lowest fresh weight per plant (5.89 g) from V0. Considering the light quality application, L4 produced the highest fresh weight per plant (15.83 g) and the lowest fresh weight per plant (2.52 g) was from L3. Regarding the interaction effect, the highest fresh weight per plant (21.58 g) was obtained from treatment combination V2L4 and the lowest fresh weight per plant (1.87 g) from V0L3. So, the vermicompost dose, 45 % vermicompost + 45 % cocopeat + 10 % broken bricks/pot with combined red and blue light can be used for herbage production of peppermint.
