The objective of this review is to know about the major crops, vegetables, fruits, medicinal plants, and cash plants materials and women's participation in home garden agroforestry practices in Bangladesh. The various species of home gardens are nutritionally and economically valued as they fulfill a demand. Women are more engaged than men in home garden activities. Common vegetables, fruits contain significant amounts of protein, sugars, salts, calcium, iron, vitamins, minerals, thiamin, riboflavin, niacin, potassium, calcium, zinc, magnesium, and iron. The common medicinal plants are using plant parts such as fruit, leaf, bark as treatment of dysentery, cough, fever, and other diseases. The flower plants improve beautification in the home and also contain the aesthetic value. The profit plant helped in the economic sector. The responsible bodies should undertake positive actions like promoting specific study plans in the home garden to ensure biological balance to improve the capacity of women communities to manage and maintain home garden diversity.

It is synthesized in the skin after ultraviolet radiation exposure or obtained in the diet to a less extent. Vitamin D deficiency is attracting attention due to higher prevalence in different populations. Physicians of Bangladesh are supposed to be vulnerable to low Vitamin D levels owing to long indoor work hours in both government and private settings. The study was conducted to evaluate Vitamin D status among physicians working in a tertiary level public hospital of Bangladesh. The cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to June 2018. Data were collected from purposively selected 102 doctors of different levels using a case record form. Interview, measurements and laboratory investigations were done accordingly. Vitamin D levels were categorized as deficient (<20.00ng/L), Insufficient (20.00-29.00ng/L), Sufficient (30.00-100.00ng/L) and Potential Toxicity (>100.00ng/L). Among 102 doctors 79(77.5%) were male and 23(22.5%) were female. Maximum (60.8%) were in the age group of 31 years to 50 years. Mean±SD age of the subjects was 49.9±3.61years. Vitamin D deficiency was found in 19(18.6%) subjects and insufficiency was in 49(48.0%) of the subjects. On the other hand 34(33.3%) subjects had sufficient Vitamin D levels. Potential Vitamin D toxicity was not found in any of the subjects. Vitamin D deficiency was found more in female (30.4%) than male (15.2%) but insufficiency was found more in male (50.6%) than female (39.1%). The study revealed that 66.6% physicians had either deficiency or insufficiency of Vitamin D. Exposure to sunlight, dietary intake and Vitamin D supplementation should be considered to increase the status of Vitamin D levels in Physicians of Bangladesh.

The main objective of this study is to analyze the positive and negative impact on the human and environmental situation of COVID-19 in the world. many research works were done on individual issues for one state of a country but not all state or country data are not available in any sources of the world. To accomplish this goal, preliminary analysis, review articles and reviews released over the past five years have been analyzed with various research data such as NCBI, EMBASE, Google Scholar, PubMed/MEDLINE and MDPI from related clinical trials and animal studies with English terms search: COVID-19, lockdown, financial problem, environmental health problems. The COVID-19 was declination of the GDP, remittance, market policy, private sector credit, tourist industry, employment status, health emergency, shock in education, restrictions in recreation and created pollution like as water, microplastic pollution. The positive effect of covid-19 was the reduction in air and noise pollution, regeneration of biodiversity, and established digital transformation in the world. However, this virus delimited financial sectors have also donated towards a good environment. If COVID-19 and lockdown are released, environmental pollution will increase more in the world. As a result, this research recommends that the policy makers must promote in the financial sector without Khan, et.al, 2022 Azerbaijan Medical Journal 4182 disturbing the environmental elements or create a new fund to help the environmental organizations.

Its importance is immense for controlling pests in developing countries like Bangladesh. But the imprudent application is increasing at an alarming rate due to which environmental degradation is increasing, which is not still under investigation. Despite the various pest control methods, chemical pesticides (hereafter pesticides) are more popular among Bangladeshi farmers because of their low cost and rapid action. The continuous popularity of pesticides application adversely affects the environment, and eventually, human throughout the country. Hence a systematic review was initiated utilizing the secondary information to overview the hazardous impact or prevailed pollution due to the application of pesticides in the context of the environment, related organisms, and human health. The analysis revealed that pollution-related problem arises mostly due to the unregulated use of pesticides. Therefore, excessive pesticide usage such as pollutes the air, soil, and water and kills non-target organisms, causing an ecological imbalance. Lack of protection exposes farmers to acute illnesses, toxic compounds in the food cycle, and the mass population to chronic health issues. Thus, to minimize pesticides' environmental, and health effects, concerns should be given on the judicious application of pesticides, raising awareness regarding pesticide use. Policymakers should focus on raising awareness regarding the use of pesticides, implementing effective pesticide usage laws at the root level, optimizing reasonable use, participatory program implementation for farmers' training, good governance and regulatory mechanisms, frequent inspection at the field level, and appropriate actions and strategies for promoting eco-friendly methods.

It promises to ameliorate nutritional demand from vegetables and has an excellent possibility for the world market. But the production is hampered due to infection of several diseases in field conditions. Research Method: This study was undertaken based on secondary data of existing literature from Bangladesh and other parts of the world. So far, many research works were done on this issue but those were not available to the policymakers, extension workers, and public in a systematic manner to date. Findings: In this paper, we tried to bring forth different aspects of phytopathological problems of country bean. It usually undergoes stresses from different soilborne to seed-borne pathogens and expresses symptoms from the seedling stage to maturity. Crop protection largely depends on the integration of host plants, seeds, agronomic practices, environmental footprints, and the use of appropriate agrochemicals based on the epidemiology of target pathogens. Here, we have also described effective management strategies against respective pathogens of the diverse category. These microorganisms attack at different stages of crop growth and can affect the host plants enormously to cause maximum yield loss. Research Limitations: The study focused on the management of country bean diseases based on biological and chemical approaches. It presents limited information on specific technologies in different agroecological zones. Originality/ Value: This study identified research gaps among Bangladesh and other countries. It also provides information to combat country bean diseases to the economic threshold level for ensuring sustainable crop yield.

The study sample consisted of 80 randomly selected lemon growers who were interviewed and the data were collected to identify their perceptions, social characteristics, and the impact of climate change on lemon production. The results of the survey indicated that the grower's perception of climate change was impactful as a majority of growers claimed increased annual precipitation (48.8%), increased summer temperature (48.8%), and reduced winter temperature (46.3%). In the case of extreme events, 56.3% of growers mentioned that the intensity of storms has increased in the last 5 years (2015-2019) and 58.8% of lemon growers said that the intensity of rainfall had increased substantially. However, in terms of environmental hazards, the findings indicate that excess rainfall, pest infestation, cloudy skies, hail storms, and drought are the major problems in lemon production. On the surface, overcast skies cause most of the damage to lemon production. Apart from this, soil fertility, pests, diseases, excess temperature, crop sowing time, maturity period, and drought had a significant impact on lemon production in the study area. From the correlation coefficient table, it appears that many socioeconomic characteristics were also influenced by the impact of climate change on lemon production. In the study area, there is a positive significant relationship between changes in lemon production and changes in environment and risks. The lemon crop requires moderate temperatures and average rainfall for improved production.

There were 10 treatments : T 1 = Sadakoroi (leaf biomass 2 kg /plot) + 15% RFD (Recommended fertilizer dose), T 2 = Sadakoroi (leaf biomass 2 kg /plot)+ 30% RFD, T 3 = Sadakoroi (leaf biomass 2 kg /plot)+ 45% RFD, T 4 = Kalokoroi (leaf biomass 2 kg /plot) + 15% RFD, T 5 = Kalokoroi (leaf biomass 2 kg /plot) + 30% RFD, T 6 = Kalokoroi (leaf biomass 2 kg /plot) + 45% RFD, T 7 = Akashmoni (leaf biomass 2 kg /plot) + 15% RFD, T 8 = Akashmoni (leaf biomass 2 kg /plot) + 30% RFD, T 9 = Akashmoni (leaf biomass 2 kg /plot) + 45% RFD and T 10 = Control (100% RFD). The boro hybrid rice var. SQR6 was used as a test crop. The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replications. The result showed that green leaf biomass had a significant effect on the yield contributing characters. The panicle length varied from 21.0 to 25.5 cm. The number of leaves on hill-1 varied from 40.2-25.9. The number of effective tillers on hill-1 varied from 12.27-10.63. The highest grain yield of 8.87 t ha-1 was obtained from treatment T 10 followed by 8.77 tha-1 noted with T 3 where Sadakoroi leaf biomass was applied. Therefore, this study suggests that the green leaf biomass of Sadakoroi and Kalokoroi can be applied to the improvement of yield and yield contributing characters of rice.

An experiment was undertaken to elucidate the genetic variability in five inbred parents and their 17 F4’s derivatives in pea evaluating ten characters during the winter season of 2017-2018 at the research farm, BSMRAU, Gazipur, Bangladesh. Analysis of variance explored significant differences among the genotypes for all the characters. Phenotypic coefficients of variation were close to genotypic coefficients of variation for all the characters indicating less influence on the environment and potentiality of selection. High heritability associated with high genetic advance was observed for plant height, pod per plant, hundred seed weight, and seed yield per plot. Days to 50% flowering and days to first flowering showed a highly significant positive correlation at both genotypic and phenotypic levels. Plant height showed a highly significant positive correlation with pods per p...
