The Jackfruit (Artocarpus heterophyllus L.) is well-known as “poor man’s food” fruit in Bangladesh. It is widely consumed by most of the rural people and it is the national fruit of Bangladesh. The main aim of this review is to document the medicinal significance of jackfruit (Artocarpus heterophyllus L.), major parts and uses of the jackfruit in Bangladesh. This article was based on mostly a literature review. All parts of the fruit and plant are used as human food, animal feed and wood source for furniture. Although jackfruit is the main fruit of the tree, it is used as furniture for its beautiful texture and wood color. Jackfruit contains anti-bacterial, anti-diabetic, anti-oxidant, anti-inflammatory and anti-helminthic properties. The fruit is rich in carbohydrates, minerals, carboxylic acids, dietary fiber, vitamins and minerals. The seed is rich in manganese, magnesium, potassium, calcium iron and lectins and thus meets up nutritional requirements for the rural people. The present study attempted to review the medicinal importance, health-promoting effects of jackfruit and seeds with special emphasis on their applications in the food.

Chrysanthemum is a floricultural, ornamental and medicinal plant with tremendous income cash crop which is cultivated chiefly in winter. The crop charity as nerve sedative, anti-oxidant, anti-inflammatory, anti-mutagenic, anti-microbial, anti-fungal, anti-angiogenic, anti-atherosclerosis and nematocidal goods. Chrysanthemum has been used for hundreds of years in manufacturing medicine. It is used to treat respiratory complications, high blood pressure, and hyperthyroidism and reduce inflammation. Leaves remedies for colds, headaches, bronchitis, rheumatism, and swellings. The plant has aesthetic significance as well. Nevertheless, outbreaks of pests and diseases have hold back Chrysanthemum cultivation in Bangladesh. Insect pest damages the plant directly by sucking cell sap and indirectly spread out of virus diseases as act of vector. Aphid resistance variety might be the effective tool for successful production of chrysanthemum plant. Sustainable crop disease management for Chrysanthemum needs a multitude of consideration of the impacts of management methods on economics, sociology and ecology by wholly understanding the mechanisms of crop disease epidemics and the functioning of normal agroecosystems. The findings of this study present clear insights into efforts that will encourage farmers to adopt effective and ecological methods of pest and disease management for successful chrysanthemum production in Bangladesh.

Cinnamon (Cinnamomum verum Presi.) is important spice in the world which is cultivate in tropical and subtropical region of the world. It is widely used as beneficial spices and pharmacological agents from the inner bark of plants. The study is fully based on the use of secondary sources of data; related journals, government institutes, and related reports. Medically, this plant is very important but its production is humper due to insect pests and diseases are main barriers for the production of cinnamon fruit. The objective of this study was to document the insect pests and diseases of cinnamon and their management in agroforestry system compared to different cinnamon growing countries. Since many research works were done on these issues but all are not available to the policy makers, extension workers and public in a systematic manner to date. The major insects are jumping plant louse (Trioza cinnamomic), mite (Eriophyes boisi), common mime (Chilasa clytia Lankeswara, Moore), blue bottle (Graphium sarpedon Teredon), leaf and shoot Webber (Orthaga vitialis), hairy caterpillar (Euproctis fraternal Moore), wood boring moth or hairy tussock moth (Dasychira mendosa), fruit borer (Alcides morio Heller), leaf miner (Acrocercops spp.), and sorolopha semiculta (Olethreutes semiculta) and major diseases are leaf spot and die back (Colletotrichum gloeosporioides), seedling blight (Diplodia sp.), grey leaf spots/blight (Pestalotia cinnamomic), black sooty mould (Stenella spp.), algal leaf spots (Cephaleuros virescens), stripe canker (Phytophthora cinnamomi), pink disease (Corticium salmonicolor B. and Br.), brown root rot (Phellinus lamaensis Murr.), and leaf spot/blight (Colletotrichum gloesporioides). The paper eventually would help to increase the productivity of C. verum through the management of its insect pests and diseases.

A field study conceded to assess the effect of pinching on growth and quality flowers yield of chrysanthemum at Horticulture Research Centre (HRC), Gazipur, Bangladesh. The research was laid out in Randomized Complete Block Design (RCBD) with six treatments and three replications. The treatment combinations were as T0- No pinching, T1- Once 40 days, T2- Once 50 days, T3- Once 60 days, T4- Twice 40 and 50 days and T5- Thrice 40, 50 and 60 days. It was observed that the highest plant height 60cm in no pinching (T0) and the lowest 45 cm was recorded by pinching the plants thrice (T5). Days of the first flowering (57 days) was observed where no pinching was followed and significantly delay in flowering (68 days) was recorded in in pinching the plants thrice (T5). The highest number of branches (12) was recorded in pinching the plants thrice (T5) and the lowest number of branches (05) in no pinching (T0). The maximum number of leaves (235) was recorded in pinching the plants thrice (T5) and minimum number of leaves (200) was observed in no pinching (T0). The treatment T5 (pinching the plants thrice) attained maximum plant spread (30 cm) and the treatment T0 (no pinching) attained minimum plant spread (17cm). The highest number of flower (45) was recorded in pinching the plants thrice (T5) treatment and the lowest flower (28) was observed in T0 treatment. Among the six treatment, T5 (pinching the plants thrice) showed the highest efficacy and it could be used as treatment in cultivation of Chrysanthemum indicum for growth and quality flower production.

Background: In Bangladesh, the Institute of Epidemiology, Disease Control and Research (IEDCR) reported the first COVID-19 positive patients in the country on March 8, 2020. The world health organization (WHO) declared a COVID-19 epidemic on March 11, 2020. The aim of this study was related to the situation and relation of tests, infested, recovered and death of people against COVID-19 of Bangladesh. The study was carried out from 8 March 2020 to 30 April 2021 (N=419 days) to observe the status of Bangladesh towards rampant COVID-19. Methods: The data of this research was collected from IEDCR, Directorate General of Health Services (DGHS), Ministry of Health and Family Welfare (MoHFW), and cross-checked with different newspapers and online news portals. Correlations were made using Spearman's rank correlation coefficient. Results: The total tests, infection, recovered and died were 5357294, 747761, 669995 and 11250; respectively in Bangladesh. The tests of COVID-19 were 1482, 69252, 244064, 460528, 409503, 362113, 397452, 389452, 436862, 454892, 424034, 392403 and 722848 in March to December, 2020 to January to April 2021; respectively in Bangladesh. The infestation of COVID-19 was 49, 7616, 39486, 98330, 92125, 73070, 50457, 44205, 57248, 58948, 21629, 11077 and 128555 in March to December, 2020 to January to April 2021; respectively in Bangladesh. The recovered of COVID-19 was 25, 135, 7904, 34845, 76517, 69452, 71600, 48658, 56099, 70367, 22285, 17140 and 150816 in March to December, 2020 to January to April 2021; respectively in Bangladesh. The death of COVID-19 was 6, 163, 472, 1198, 1264, 1125, 970, 666, 718, 938, 568, 277 and 2237 in March to December, 2020 to January to April 2021; respectively in Bangladesh. The maximum number of people infested and death in April, 2021. The positive correlation found between infested with tests and recovered with tests of April, 2021 by people where (R2= 0.5289, p<0.012 and 0.0000006 p<0.05) and the negative correlation found between tests with date and death with tests (R2= 0.2567, p<0.01 and 0.3614, p<0.01). All the Spearman correlation positive with moderate to strong relation between the variables at the 0.01 level in two-tailed and the total number was n=419. The mean Spearman correlation for tests was 0.31 (range 0.553 to 0.634), for infested was 0.35 (range 0.611 to 0.880), for recovered was 0.796 (range 0.634 to 0.799), for death was 0.808 (range 0.553 to 0.880). March to December 2020 and January to February 2021, not much less than April 2021. Conclusions: More people infested and died in April, 2021 than previous year. This study also indicated that there is moderate to strong relation among tests, infested, recovered and death with COVID-(2020-2021).
