    A Thesis Submitted to Department of Entomology, Faculty of Agriculture. Sher-e-Bangla Agricultural University, Dhaka- In partial fulfillment of the requirements for the degree of MASTERS OF SCIENCE (MS) IN DEPARTMENT OF HORTICULTUREA field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, from June 2021 until October 2021 to evaluate the influence of Clybio (biostimulant) concentrations on the growth and productivity of summer onions (Allium cepa). The variety used was BARI Piaz-3. The single factorial experiments were laid out in a Randomized Complete Block Design (RCBD) with three replications. The experiment consisted of four treatments, namely, T 0 = control (no Clybio application), T 1 = Clybio @ 2 ml/L, T 2 = Clybio @ 4 ml/L and T 3 = Clybio @ 6 ml/L, and in total, this was applied six times, starting from 10 DAT until 60 DAT and were applied in a foliar manner to both leaves and surrounding soil. Among the treatments, the maximum plant height (60.8cm), the number of leaves per plant (16.7), leaf length (54.2cm), leaf weight (31.3g), diameter of pseudostem (11.9mm), root length (8.4cm), number of roots (33.0), bulb diameter (43.8mm), bulb length (52.7mm), weight of a single bulb (45.7g), average bulb yield per plot (33.2 t/ha) was recorded at T 3 treatment. The highest length of pseudostem (49.4 mm) was found in the T 1 treatment. On the contrary, the minimum plant height (38.3cm), number of leaves per plant (7.0), leaf length (24.1cm), leaf weight (17.7g), root length (4.5cm), number of roots (26), bulb diameter (22.7mm), bulb length (42.0mm), weight of a single bulb (22.0g), average bulb yield per plot (16.0 t/ha) was observed at T 0 (control) treatment. The lowest diameter of the pseudostem was found at the T 1 (7.5mm). No statistically significant variation was found in the length of the pseudostem (mm) in response to different treatments. When compared to control (T 0 ), the highest increase in yield percentage was observed at T 3 treatment (107.5%) . A highly significant, very strong (R 2 = 0.99) and positive correlation was discovered between bulb weight and root length, indicating that bulb weight increased as root length increased. Considering the aforementioned findings, T 3 (Clybio @ 6 ml/L) treatment delivered the best results in terms of growth and yield attributes of summer onions

Sher-e-Bangla Agricultural University, Dhaka- In partial fulfillment of the requirements for the degree of MASTERS OF SCIENCE (MS) IN ENTOMOLOGYThe study on host plant preference of aphid and predation efficacy of ladybird beetles on aphid was conducted at Sher-e-Bangla Agricultural University central farm and the laboratory of the Department of Entomology, SAU during November 2020 to April 2021. Two experiments were conducted to explore the host plant preference of aphid and the predator efficiency of ladybird beetle. They were laid out in Randomized Complete Block Design (RCBD) for field condition and Complete Randomized Design (CRD) for laboratory condition with 3 replications. There are six different crops as treatment-wheat, brinjal, tomato, potato, country bean and mustard. The highest number of aphid (54.51 plant -1 ) was recorded in Country bean at 7 DAS and the lowest (8.00 plant -1 ) number of aphid was recorded in Brinjal plant at 35 DAS. The highest number of aphid (29.67 leaf -1 ) was recorded in Country bean at 35 DAS and the lowest (8.00 leaf -1 ) number of aphid was recorded in Wheat plant at 14 DAS. The highest number of aphid (9.67 inflorescence -1 ) was recorded in Country bean at 14 DAS and the lowest (3.00 inflorescence -1 ) number of aphid was recorded in Wheat plant at 14 DAS. The highest number of aphid (15.67 twig -1 ) was recorded in Country bean at 7 DAS and the lowest (11.00 plant -1 ) number of aphids was recorded in Brinjal plant at 35 DAS. The highest number of aphid (6.00 pod -1 ) was recorded in Country bean and the lowest (5.94 pod -1 ) number of aphids was recorded in Brinjal plant. The highest consumption of aphid (3.10 aphid) by Ladybird beetle was recorded in Country bean at 12 hours interval and the lowest consumption of aphid (1.10 aphid) by Ladybird beetle was recorded in Wheat at 6 hours interval. The adult ladybird beetles was more efficient in predating aphid and the highest consumption of aphid was recorded from adult ladybird beetles

    A Thesis Submitted to the Department of Development and poverty studies Sher-e-Bangla Agricultural University, Dhaka, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN DEVELOPMENT AND POVERTY STUDIESThe present study was designed to assess the profitability and factor affecting of potato cultivation in different land tenure systems of some selected areas of Munshiganj district in Bangladesh. Farmers were randomly selected for data collection purposes. The selected upazilas were Munshiganj Sadar under the Munshiganj district. Descriptive statistics and Cobb-Douglas production function were used to achieve the objective of the study. The major findings of the study revealed that potato production was profitable for the year 2022. Per hectare, the average yield for owner farmers (Tenure-1) was 31559.38 kg and for rented in farmers (Tenure-2) was 31931.82 kg. Overall expenses of potato production have been Tk. 2,42265.3 in Tenure-1 and Tk. 250553.8 in Tenure 2. Per hectare net returns of potato production were Tk. 168006.7 in Tenure 1 and Tk. 100696.2 in Tenure 2. Undiscounted (BCR) of potato production consistent with hectare came out to 1.69 in Tenure 1 and 1.40 in Tenure 2. The results of the Cobb-Douglas production function indicated that the gross return of the potato production was highly influenced by human labor, seed, irrigation, manure, fertilizer, insecticide, etc. The coefficient of more than one determination, Adj. 2 became 0.1252 and 0.1213 for tenure 1 and tenure 2 in the case of the potato production feature. The F- value (2.455) and (2.288) for tenure 1 and tenure 2 shows nicely match of the model. The problems faced by potato farmers were the high price of potato tuber, wages of labor, cost of storage, and problems of getting enough cash for potato cultivation, etc. So efficient policy for pricing, effective production management, and lower input price was required for the highest net return of potato cultivation. For these Bangladesh government should play a vital role in the effective management of potatoes

    A Thesis Submitted to Department of Entomology, Faculty of Agriculture. Sher-e-Bangla Agricultural University, Dhaka- In partial fulfillment of the requirements for the degree of MASTERS OF SCIENCE (MS) IN DEPARTMENT OF HORTICULTUREA pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during the period from January to September 2021, to investigate the effect of growing media on growth, yield and quality of different summer tomato cultivars in hydroponic culture. The experiment consisted of two factors, and followed completely randomized design (CRD) with three replications. Factor A: Four tomato cultivars viz; V 1 = BARI Hybrid Tomato-4 ,V 2 = BARI Hybrid Tomato-8,V 3 = BARI Tomato-10 , = BARI Tomato-13, Factor B: Four types of growing substrate mixtures, viz. M 1 = 60% coconut coir + 30% khoa + 10% vermicompost , M 2 = 60% rice husk + 30% coconut coir + 10% vermicompost , M 3 = 60% sawdust + 30% khoa + 10% vermicompost , and M 4 = 60% ash + 30% khoa + 10% vermicompost. This experiment examined the physicochemical attributes of various combinations of growing media, as well as the growth, production, and physiological qualities of different varieties of summer tomato. The highest pH (7.92) was found in M 4 which was not suitable for summer tomato production while suitable pH (6.10) was found in M 1 . Water holding capacity, air filled porosity and dry weights of substrate mixtures were higher in M 1 V 4 and lower in M 3 . The highest number of fruits plant -1 (32.25), fruit polar length (4.53 cm), fruit radial length (4.3 cm), individual fruit fresh weight (79.46 g), individual fruit dry weight of tomato (5.01 g) and yield plant -1 (2.58 kg) was found in (M 1 ) based growing substrate. In case of different tomato cultivars the highest yield plant -1 (2.52 kg) was found in BARI Hybrid Tomato-8 cultivar (V 2 ). In case of combination, the highest fruit plant (39.5), fruit polar length (5.01 cm), fruit radial length (4.7 cm), individual fruit fresh weight (92.28 g), fruit dry weight (6.23 g), yield plant -1 (3.59 kg) and fruit volume (475.39 cc) was found in M 1 V 2 . Based on the evidence, it can be concluded that BARI Hybrid Tomato-8 cultivar is suitable for cultivation in M 1 media, a mixture of 60% coconut coir, 30% khoa and 10% vermicompost and can result in higher yield and better quality tomato in hydroponic culture

    A Thesis Submitted to the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka in partial fulfillment of the requirements or the degree of CAUSED BY Alternaria spp. MASTER OF SCIENCE (MS) IN PLANT PATHOLOGYMungbean (Vigna radiata L.) is an excellent and easily digestible dietary source of plant protein. Mungbean yellow mosaic disease caused by Mungbean yellow mosaic virus (MYMV) which is transmitted by whitefly (Bemisia tabaci), an important constraint of mungbean cultivation. A field experiment was conducted at the central farm of Sher-eBangla Agricultural University (SAU), Dhaka during March to June, 2021. The prime aim of the study was to manage the Mungbean yellow mosaic virus (MYMV) by controlling the insect vectors using barrier crops (sesame, linseed, maize, coriander) and colored plastic mulches (red, blue, silvery-grey, black). BINA released variety BINAmoog-5 was used as a planting material in the experiment. Morphological and physiological parameters were all considerably impacted in this study. Disease incidence and percent disease index of MYMV was significantly varied among the treatments. The lowest disease incidence (5.35%, 8.95%, 17.91% per plot and 5.24%, 11.75%, 19.09% per plant at 30, 45 and 60 DAS, respectively) was estimated when maize was used as a barrier crop while the highest disease incidence (25.92%, 35.52%, 61.10% per plot and 27.66%, 34.15%, 59.72% per plant at 30, 45 and 60 DAS, respectively) was found in control treatment. In case of colored plastic mulches, the lowest disease incidence (8.56%, 14.35%, 23.91% per plot and 8.23%, 15.76% 24.70% per plant at 30, 45 and 60 DAS, respectively) was recorded when silvery-grey colored plastic mulch was used. The lowest percent disease index (5.55%, 13.39% and 20.16% at 30, 45 and 60 DAS, respectively) was also found when maize was used as a barrier crop. In case of colored plastic mulches the lowest percent disease index (7.42%, 17.97% and 26.70% at 30, 45 and 60 DAS, respectively) was computed when silvery-grey colored plastic mulch was used. Again, the highest percent disease index (28.14%, 37.71% and 64.08% at 30, 45 and 60 DAS, respectively) was found in control treatment. The highest chlorophyll content, number of flower, pod and yield was measured and counted when maize was used as a barrier crop and silvery- grey colored mulch was used as a colored plastic mulch. However, maize or silvery-grey colored plastic mulch uniquely or combindly can be used to control whitefly (vector) for the management of MYMV

    ABSTRACT The purpose of the study was to determine the effectiveness of dietary supplements of papaya leaf meal (Carica papaya) and black cumin (Nigella sativa) seeds on the production index and hematological status of commercial broiler chicken. T1 (Control), T2 (antibiotic), T3 (2% PLM: Papaya Leaf Meal), T4 (1% BCS: Black Cumin Seed) and T5 (1% of each PLM & BCS) were the five treatment groups that the 150day-old Cobb 500 straight run chicks were randomly assigned. Ten chicks were used in each of the three replications of each treatment. The findings demonstrated that feeding broilers supplements of PLM and BCS did not significantly (p>0.05) affect feed consumption (FC) (g), final live weight (g) and feed conversion ratio (FCR) when compared to the control and antibiotic group. FC was found to be numerically (p>0.05) higher in the control group than in the other groups. However, the T3 group of birds given 2% PLM had superior ultimate live weight and an improved FCR value compared to antibiotic, control, and the values of the other groups, which were statistically insignificant (p>0.05). The relative weight of the spleen in various groups was unaffected (p>0.05) by dietary supplementation with PLM and BCS. But the T3 (2% PLM) group had significantly (p<0.05) increased bursa weight (g). The concentrations of glucose and cholesterol were similar across all groups (p>0.05), while the group receiving 2% PLM supplements had relatively lower cholesterol levels (mg/dl). Moreover, the supplemented groups with PLM and BCS revealed a significant (p<0.05) increase in the hematological parameters red blood cell (RBC), white blood cell (WBC), lymphocyte, and packed cell volume (PCV) as compared to the antibiotic and control groups. The final live weight, FCR, immune organ weight, and blood indices were all improved in birds fed a meal supplemented with 2% PLM, leading to superior results

    A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN SOIL SCIENCEA pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh during the period from January 2022 to July 2022 to examine the response of organic and inorganic fertilizers on growth and yield of rice (Oryza sativa). The experiment consisted of eight treatments viz. T 0 (Control, no nutrient application), T 1 ii (100% RDCF: N 120 P 20 K 40 S 20 ), T 2 (100% Cow dung: 10 t ha -1 ), T 3 (100% Poultry Manure: 5 t ha (50% RDCF + 50% Cow dung), T 5 (50% RDCF +50% Poultry Manure), T 6 (25% RDCF + 75% Cow dung), T 7 (25% RDCF + 75% Poultry Manure). The pot experiment was laid out with two factors following randomized complete Block design (RCBD) with three replications. A significant variation was found among the treatments while different nutrient levels (organic and inorganic) applied in different combinations. The treatment T 4 (50% RDCF + 50% Cow dung) exhibited the highest plant height at 30, 60, 90 DAT and at harvest (55.35, 72.30, 85.24 and 99.00 cm respectively). The treatment T 4 (50% RDCF + 50% Cow dung) also showed the highest number of tillers hill -1 (26.49, 31.33, 36.58 and 28.67 respectively), whereas control treated pot T 0 (no nutrient application) showed the minimum results. Again, the treatment T 4 (50% RDCF + 50% Cow dung) showed the highest Grains Panicle -1 (98.16), Panicle Length (17.33 cm), 1000 Seed Weight (21.08 g), Grain Yield (5.95 t ha -1 Zn 2.5 -1 Kg ha ), T 4 ), Straw Yield (8.42 t ha ), Biological Yield (8.79), Harvest Index (50.33%) followed by T 5 (50% RDCF +50% Poultry Manure) and T 7 (25% RDCF + 75% Poultry Manure) in some case whereas the control treatment T 0 (no nutrient application) performed the lowest results on the respected parameters. So, the treatment T 4 (50% RDCF + 50% Cow dung) can be considered as suitable treatment for rice production (BRRI dhan28) to obtain higher grain yield

    A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGROFORESTRY AND ENVIRONMENTAL SCIENCEArsenic (As), which is a highly toxic metalloid poses a serious risk to plants, animals and human health has become a major public concern in many countries including Bangladesh. A pot experiment was conducted with four different levels of arsenic at Agroforestry and Environmental Science field of Sher-e-Bangla Agricultural University, Dhaka. There were four different arsenic levels viz. T 1 : Control (No arsenic in the soil); T 2 : 25 mg As kg ii -1 soil; T 3 : 50 mg As kg : 75 mg As kg -1 soil. Different data on growth and yield attributes were collected and analyzed statistically. It was observed that T 1 (no arsenic) treatment exposed the best results in terms of plant height, stem diameter (cm), number of leaves, leaf length (cm), leaf breadth (cm), length and weight of shoot and root, number of flowers and fruits, fruit length, fruit diameter and fruit weight of brinjal plant compared to other treatments. The maximum fruits (3.75) were observed in treatment T 1 (no arsenic in the soil) at 80 DAT which was significantly different from the others. Hence, from this study, it might be concluded that cultivation of brinjal plant was sensitive to arsenic stress and yield loss occurred with higher concentrations of arsenic. The treatment T 1 (no arsenic in the soil) exhibited the best result on growth as well as yield response of brinjal plant followed by T 2, T 3 and T 4

    A Thesis Submitted to the Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGRICULTURAL CHEMISTRYA pot experiment was conducted to study the effects of salinity on growth, yield and nutrients content of capsicum during the period of November 2021 to March 2022 at the net house and laboratory of Agro Environmental Chemistry, Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207. Two capsicum varieties viz. V 1 (ASTHA F1) and V 2 (BARI capsicum-1) were taken to study the effects of salinity on growth, yield and nutrients content at five levels of salinity viz. S 0 (0 dS/m), S 1 (3 dS/m), S 2 (6 dS/m), S 3 (9 dS/m) and S 4 (12 dS/m). The experiment was laid out in Completely Randomized Design (CRD) with three replications between two varieties, V 1 (ASTHA F1) showed better result on growth parameters, yield contributing characters, and yield. The higher fruit yield plant -1 was recorded from V 1 (ASTHA F1) as compared to V 2 (BARI capsicum-1). Different salinity levels showed significant effects on growth and yield parameters of capsicum. Salinity levels did not show positive effects on growth and yield of capsicum. Growth parameters and yield of capsicum decreased with the increase of salinity levels. The control treatment S 0 (0 dS/m) gave the highest capsicum yield (g plant ) followed by S 1 (3 dS/m); whereas S 4 (12 dS/m) produced lowest yield. The variety Astha F 1 was found superior to BARI Capsicum-1 in respect to growth and yield of capsicum and highest number of fruits (7.60) single fruit weight (79.87 g) and yield plant -1 (607.01 g) were achieved with Astha F1 variety of capsicum when no salinity was used. All the parameters studied reduced with increase in levels of salinity. Nutrients content studied were also affected due to increase in salinity except Na

    A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGRONOMYA field experiment was conducted in the experimental field of Sher-e-Bangla Agricultural University to find out the combination effect of variety and different fertilizer level on the yield of soybean, cultivated during December, 2021 to April, 2022. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The four varieties included in this study were BINAsoybean5; BU soybean 2; BARI Soybean-5 and BARI Soybean-6. There were four fertilizer combinations. Such as F 0 = No fertilizer, F 1 = 50% less than recommended dose of fertilizer (RDF); F 2 = Recommended dose of fertilizer (RDF); F 3 = 50% more than recommended dose of fertilizer (RDF). Among all the varieties, BU soybean 2 (V 2 ) emerged as the superior performer, showcasing the tallest plant height at harvest (59.55 cm), highest dry weight plant -1 at harvest (6.94 g), maximum number of pod plant -1 (29.75), seed pod -1 (2.60), weight of 100 seeds (14.03 g) and leading seed and stover yield of 3.20 t ha -1 and 5.53 t ha -1 , respectively. On the other hand, among the fertilizer doses, F 3 (50% more than recommended dose of fertilizer), proved most effective, yielding the tallest plant at harvest (60.28 cm), highest dry weight plant at harvest (6.76 g), maximum number of pod plant -1 (32.73), seed pod -1 (2.44), weight of 100 seeds (12.29 g), and the leading seed and stover yield of 3.21 t ha respectively. But in the case of combination between varieties and different doses of fertilizer, V 2 F 3 (BU soybean 2 with 50% more fertilizer than the recommended dose) treatment gave the best results. The tallest plant at harvest (67.55 cm), highest dry weight plant -1 at harvest (7.49 g), maximum number of pod plant -1 -1 and 5.75 t ha (35.61), seed pod (3.00), weight of 100 seeds (15.52 g), leading seed and stover yield of 4.52 t ha and 7.22 t ha -1 was recorded in V 2 F 3 (BU soybean 2 with 50% more fertilizer than the recommended dose). It may be concluded that the BU soybean 2 (V 2 ) variety and the F 3 fertilizer dose individually exhibited notable results, but their combination in the V 2 F 3 treatment yielded unparalleled performance, achieving the most impressive growth and highest seed and stover yields, highlighting the profound impact of optimizing both variety and fertilizer
