    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 SCIENCELight stress is a limiting factor for crop production, especially in agroforestry system. A pot experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka- 1207, during the months of October 2019 to mid-April 2020 in a completely randomized design (CRD) to determine the effect of low light on morpho-physiology and yield of tomato. Three tomato varieties viz. BARI Tomato-2, BARI Tomato-15, BARI Tomato-16 were exposed to four light intensities including 100% (S 0 , control), 75% (S 1 ) , 50% (S 2 ) , and 25% (S 3 ) to evaluate their performances. Light stress (mainly S 2 and S 3 ) substantially hampered the plant growth, development as well as yield. Low light stress primarily reduced the photosynthetic performance of plants which contributes in reduction of plant height, number of primary branches, and leaves of all tomato plants. Moreover, low light intensity negatively affected the fresh and dry weight of tomato. It also decreased the number of fruits, fruit length, fruit diameter, and individual fruit weight in all varieties. As a result, plant wise tomato production was hampered seriously with low yield. In comparison with control, S 1 condition decreased tomato yield per plant by 22.5, 16.9 and 15.3% in BARI Tomato-2, BARI Tomato-15 and BARI Tomato-16, respectively. Under S 2 condition, tomato yield per plant decreased by 38.7, 37.4, and 32.7% in BARI Tomato-2, BARI Tomato-15 and BARI Tomato-16, respectively, in contrast to control. Lastly, S 3 condition decreased tomato yield per plant by 73.1, 67.0 and 62.1% in BARI Tomato-2, BARI Tomato-15, and BARI Tomato-16, respectively, compared with control. From this result, it was clear that BARI Tomato-16 was more tolerant to low light stress than BARI Tomato-2 and BARI Tomato-15

    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 GENETICS AND PLANT BREEDING SEMESTER: JULY-DECEMBER, 2021A field experiment was conducted to evaluate twenty brinjal genotypes by calculate thesignificance of variation, heritability, genetic advance, correlation, path coefficient andgenetic diversity for thirteen yield contributing characters. The experiment was executed following Randomized Complete Block Design (RCBD) with threereplications at Sher-e-Bangla Agricultural University, Dhaka, from August 2019 to March 2020. In this experiment, significant differences were exhibited among the existing genotypes for all characters. Higher Phenotypic Co-efficient of Variation(PCV) than the Genotypic Co-efficient of Variation (GCV) were observed for allcharacters. Highest PCV (59.24) and GCV (58.58) were observed for % of infestedfruit. High heritability associated with high genetic advance in percentage of mean werefound with all the character except days to 1 st flowering, days to 1 st fruiting, and daysto 1 st harvesting which indicating selection on the basis of phenotype would beeffective. At genotypic level, number of primary brunches per plant (0.355), number ofsecondary brunches per plant (0.356), and fruit diameter (0.494) exhibited highlysignificant and positive correlation with yield per plant. Path analysis revealed that thenumber of flowers per plant (2.616) had the maximum positive and direct effect onyield per plant. Through genetic diversity, 20 brinjal genotypes were grouped into fourcluster. The cluster I containing the maximum number of genotypes (7) followed byCluster II (6), IV (4), and III (3). Maximum intra-cluster distance was exhibited bycluster I (1.74), whereas the highest value for inter-cluster distance was observedbetween Cluster I and Cluster III (32.04). Mean performance of cluster showed thehighest yield per plant (1.62) value in cluster IV. Therefore, considering the magnitudeof genetic distance, contribution of character towards divergence, magnitude of cluster mean performance and agronomic performance the genotype G8 (Ventura), G15 (Bt),and G17 (Kustia 2) from cluster I, G12 (Pirgonj) from cluster III, and G16 (Avo round)along with G18 (Altapon) from cluster IV would be considered as better parents forfuture hybridization programs

    A Thesis Submitted to The Department of Agronomy, Faculty of Agriculture, Sher-e-Bangla Agricultural University, Dhaka, in partial fulfilment of the requirements for the degree of MASTERS OF SCIENCE (MS) IN AGRONOMYThe experiment was conducted at the Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, from June 2021 to December 2021 to study the growth and yield of black rice (Oryza sativa L. indica) as affected by seedling age and seedling rate (no. of seedlings hill -1 ). Black rice was used as the test crop for this experiment. The experiment comprised two factors. Factor A: Seedling age (4 levels); 25 days old seedling, 30 days old seedling, 35 days old seedling, and 40 days old seedling, and Factor B: Seedling rate (no. of seedlings hill -1 ) (3 levels): 1 seedling hill -1 ; 2 seedling hill -1 and 3 seedling hill -1 . The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Due to the combination effect of seedling age and seedling rate, the maximum number of effective tillers hill -1 (14.00) was found in the treatment combination of 35 days old seedlings transplanted in 2 seedlings hill -1 and the minimum number (2.00) in 25 days seedling age with 3 seedlings hill -1 . The longest plant height (184.87 cm) was found in the treatment combination D 4 S 1 (40 days old seedling and 1 seedling hill -1 ), whereas the shortest plant (161.60 cm) was found in the treatment combination D 1 S 3 (25 days old seedling with 3 seedlings hill -1 ). The maximum number of filled grains panicle -1 (353.2) was found in the treatment combination of D 3 S 2 (35 days old seedling and 2 seedlings hill ), and the minimum number (270.73) was found in D 1 1 ). The highest grain yield (5.56 t ha -1 S 3 -1 (25 days old seedling and 3 seedlings hill ) was found in the treatment combination of D 3 (35 days old seedling and 2 seedlings hill -1 ), and the lowest grain yield (2.87 t ha ) was observed from D 1 S 1 (25 days old seedling and 1 seedling hill -1 ), but the highest straw yield (5.69 t ha -1 ) was found in the treatment combination of D 3 S 2 (35 days old seedling and 2 seedlings hill -1 ), and the lowest straw yield (3.66 t ha -1 ) was observed in the treatment combination of D 1 S 3 (25 days old seedling and 3 seedlings hill -1 ). The 35 days old seedlings planted in 2 seedlings hill -1 showed a better response in most of the studied parameters

    A Thesis Submitted to the Department of Agricultural Statistics, Sher-e-Bangla Agricultural University, Dhaka-1207, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGRICULTURAL STATISTICSFarmers are working extremely hard to boost crop yields by using more pesticides and fertilizer as a result of the rising global demand for food and the shrinking amount of arable land. But using pesticides in agriculture has had unfavorable repercussions on the environment and human health. The study was conducted to examine the determinants of pesticide use and risk protective behaviour in brinjal production in some selected areas of Bogura district in Bangladesh. Besides, attempt had given to describe the socio-economic characteristics of the brinjal farmers, to identify the factors that significantly influence farmers use of pesticides in brinjal production, to compare the use of pesticides among brinjal farmers and investigate the comparison of risk protective behaviour among brinjal farmers. Two upazilas called Shibganj and Shahjahanpur under the Bogura districts was selected purposively for the study on the basis of extensive brinjal production. Simple sampling procedure was used to select a sample of 102 respondents. Data were analyzed using descriptive statistics, Multiple linear regression coefficients of contributing determinants related to the determinants of pesticide use in brinjal. Results indicated that safety behaviors in pesticide use were inadequate, particularly in majority of the farmers were overusing insecticides, fungicides and herbicide. The majority of the farmers (40) did not use mask as a result of low education levels, high cost and low availability. Due to their low levels of education, high costs, and lack of access, the majority of farmers (34) did not know about pesticide toxicity. Findings from the Multiple linear regression coefficients model estimation indicated that use of NPK and plot size are significant at 1% level and experience, highest education level of the family and family size are significant at 5% level and significantly influenced the amount of pesticide usage. In order to allow correct pesticide usage for improved livelihoods and environmental protection, the study advised the implementation of risk protective measures, safety training programs and suitable extension services. In terms of public policy, developing and executing targeted interventions aiming at encouraging the limit of detrimental consequences of excessive pesticide use on human health and the environment

    A Thesis Submitted to the Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University, Dhaka-1207, In partial fulfillment of the requirement for the degree of MASTER OF SCIENCE IN AGRICULTURAL CHEMISTRYThe current study focused on quantifying hazardous heavy metals (Pb. Cu, and Cr) in soil-vegetables (potato, tomato, pepper, cauliflower, and cabbage) systems in different Upazilla of Bogura district in Bangladesh to assess their effect on human health and the environment. The instrumental detection method was validated according to linearity, determination co-efficient, limit of detection (LOD), limit of quantification (LOQ), accuracy, and precision. All the vegetables and their field soil had Cu concentrations lower than the maximum permissible limit set by BFSA, FAO/WHO. The concentration of Cr and Pb in vegetables exceeded the maximum allowable limit, but their field soil in different Upazilla of Bogura District did not exceed the maximum allowable limit as per FAO/WHO. For contamination factor (CF), only Pb severely contaminated the vegetables (CF>6). The contamination degree (CD) data also showed that all vegetables had severe contamination. The pollution load index (PLI) results indicated vegetable field soil of Kahaloo, and Bogura Sadar had the highest PLI, while the vegetables produced in Nandigram and Dupchanchia had the lowest PLI. The bioaccumulation factor (BF) values were found ˂1 in all vegetables for Cu, Cr, and Pb indicating trace metal transfer from field soil to consumable parts. Furthermore, the potential ecological risk factor (ERi) by single metal and risk index (PERI) results revealed lower ecological risks in vegetable fields. Health risk assessment showed that all vegetable samples were unsafe for human consumption as the carcinogenic health risk (CHR˃10 ) and noncarcinogenic health risk (HI ˃1) quotients seem more than the safe level in all vegetable samples. Findings show that heavy metal concentrations were high in vegetable fields endangering the environment and consumer health. Actions should be taken to reduce heavy metal pollution in the vegetable fields of different Upazilla of Bogura district to protect the environment and the consumer's health

    A thesis submitted to The Department of Agribusiness and Marketing, Sher-e-Bangla Agricultural University, Dhaka-1207 In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGRIBUSINESS AND MARKETING SEMESTER: JANUARY-JUNE, 2021As the demand of chicken consumption is high and rising, the amount of poultry market waste is also increasing by multiple times, which creates an alarming situation of polluting environment. By processing this waste into feather meal and poultry waste meal, manufacturers can contribute to meet the demand of protein for feed production and establishing a pricing structure. Therefore, this study was conducted to assess the present scenario of poultry feather waste, how to use it as an animal feed ingredient and its business opportunity. A survey was conducted in the 21 randomly selected poultry markets of Dhaka North City Corporation. Samples of feather and poultry waste were collected for laboratory analysis. The results found that in general in each shop producing 100 kg poultry wastes among which 2 kg is feather waste. It was estimated that Dhaka North City producing 473.7 tons of poultry waste among which 8.7 tons are feather, that are discarded as waste (survey data). Simplified processing techniques for feather meal has been developed. It was observed that 1 kilogram of feather waste can produce about 500 grams of product, presenting a considerable economic opportunity in comparison to other feed ingredients. Furthermore, the generated product has a high nutritional value while having no negative environmental impact. Proximate analysis showed that the final product contained Moisture 11.25%, Crude Protein 86.53%, Total Ash 7.31%, Crude fiber 0.73%, Crude Fat 5.03%. The total cost of producing per kilogram of feather meal is about 28 BDT which is much lower than present market price (60 BDT). There is opportunity to create yearly 1 million US$ business from the wasted feather in Dhaka city. Thus, using market waste for feather meal production could be a new opportunity to convert waste into resource and significant contribute to economy of the country significan

    A Thesis Submitted to the Faculty of Agribusiness Management Sher-e-Bangla Agricultural University, Dhaka, in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN AGRICULTURAL STATISTICSLeguminous crops like beans play a vital role to meet up our protein requirement. Beans contain 20-30% protein on a dry weight basis which is nearly three times than that in most cereals. Among all the leguminous crops, beans are very popular and nutritious vegetables in Bangladesh. Beans provide a good amount of protein in addition to vitamins and minerals. In Bangladesh total land area under bean cultivation is 15385 hectares and the production is 83,000 metric tons during 2006-2007(BBS, 2008). There is a great demand of bean seeds in the overseas market which may open a new horizon of export of this vegetables in those markets. The present study was conducted to estimate the farm productivity of bean production in Muktagacha and Fulbaria Upazila of Mymensingh district of Bangladesh. Three villages from each Upazila were specially selected for this study. In total, 80 bean farmers were selected specially for the study. Out of 80 samples, 40 were from Muktagacha Upazilla and 40 were from Fulbaria Upazila. Primary data were collected during September to October of 2021 through field visit. The required data were collected through structured interview schedule from the 80 jute farmers. The secondary information sources were DAE reports, Bangladesh economic review, BBS, different journals, newspaper, relevant websites etc. Descriptive statistics and CobbDouglas production function model were used to address the main objectives of the study. The results of the study showed that, per hectare average total cost for producing bean was Tk. 32402.38. Per hectare gross returns above cash cost from bean production was estimated Tk. 99302.06 and per hectare average net return of bean production was Tk. 66899.68. It was also expressed that net return was higher at Fulbaria upazila. The study considered human labor cost, tillage cost, seed cost, fertilizer cost, irrigation cost, and pesticides cost, these six variables. The study showed that seed cost and fertilizers cost had significant impact on bean production. The study also marked out that bean producers were facing some problems such as: low price of bean, high labor cost, unavailability of human labor, farmers not keeping any records of bean production etc. If these problems could be solved within the shortest possible time, all the bean producers could be able to earn a much higher profit than the existing level. On the basis of findings, some recommendations were made for the development of bean sector in Bangladesh

    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 HORTICULTUREAn experiment was conducted in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2019 to January 2020 to study the influence of seedling age and NAA on growth and yield of Chinese cabbage. The experiment consisted of two factors, such as Factor A: Seedling age (3 levels) as- A 1 : 15 days old seedlings, A 2 : 25 days old seedlings, A 3 : 35 days old seedlings and Factor B: Different levels of NAA (4 levels) as N 0 : 0 ppm (control), N 1 : 40 ppm, N 2 : 80 ppm and N 3 : 120 ppm. The two factorial experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different yield components and yield of Chinese cabbage were recorded. Statistically significant variation was recorded from all recorded characters due to the different levels of naphthalene acetic acid (NAA). Seedling age showed significant differences in all recorded characters. Seedling age and different levels of NAA influenced significantly on most of the parameters. Considerable highest values were recorded in head weight (1.69 kg) and gross yield (77.01 t/ha) from 25 days of seedling (A 2 ) and the lowest were recorded from A 3 and A 1 . Considerable highest values were recorded in head weight (1.53 kg) and gross yield (75.72 t/ha) from 80 ppm (N 2 ) followed by 120 ppm (N 3 ) and 40 ppm (N 1 ) of NAA and the lowest value was recorded from control treatments. Interaction effect between different seedling age and NAA also showed significant differences and the considerable yield and yield contributing characters were recorded from the treatment combination A 2 N 3 , while the treatment combination A 3 N 0 gave the lowest value. The highest gross return (Tk. 926,200), net return (Tk. 644,765) and benefit cost ratio (3.29) were obtained from the treatment combination A 2 N 3 and the lowest (Tk. 727,980, 457,139 and 2.69 respectively) were from the treatment combination A 1 N 0
