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, antidiabetic, 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, healthpromoting effects of jackfruit and seeds with special emphasis on their applications in the food.

For example, the agrarian sectors like agriculture, fisheries, and livestock are vital aspects of food systems directly affected by COVID-19. This review paper summarizes COVID-19 and its effects on the agricultural sectors. The COVID-19 affects the profit of agriculture, livestock, and fisheries and has opened up inequalities within the food chain. As a result, the epidemic has shown that our food chain is fragile. Since the worldwide population and urbanization will be raised in the coming decades, epidemics will occur more often. To that end, we have highlighted the need to ensure contingency plans and mitigation strategies about agricultural systems which would make more sustainable and resilient.

The objective of this study is to document the research gaps in insects and diseases of black pepper in Bangladesh with other growing countries. The article is based on mostly existing literature and partly field observation from Sylhet region in Bangladesh. So far, 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. In the black pepper growing countries, major insects are pollu beetle (Longitarsus nigripennis), scale insects (Lepidosaphes piperis and Aspidiotus destructor), top shoot borer (Cydia hemidoxa), leaf gall thrips (Liothrips karnyi and Gynaikothrips uzeli), and root mealy bugs (Diconocoris hewetti) and pepper whitefly (Aleurodicus disperses) and major diseases are root rot (Fusarium solani), yellow wilt (Fusarium oxysporum), nematode (Meloidogyne incognita and Meloidogyne javanica), stunt disease were reported. On the contrary, leaf blight (Colletotrichum gloeosporioides) and algae leaf spot (Cephaleuros virescens), foot rot (Fusarium solani), wilt diseases and flea beetle, ant (Tetramorium spp.), pepper white flies, spiders were reported in Bangladesh. In addition, quick wilt and slow decline infection as well as top shoot borer and pollu beetle infestation like symptoms were also observed which requires further confirmation. It is noted that, black pepper growers in Bangladesh have no idea on the insects and diseases attack and their appropriate management which hinders expansion of area and production of black pepper in Bangladesh. More attention is required for proper management of insects and diseases of black pepper in Bangladesh. Hence, direct field observation on insects and diseases of black pepper is ongoing in the black pepper germplasm centre situated in Tilagorh Eco-Park of Sylhet and agroforestry field laboratory of Sylhet Agricultural University which will be reported in the next manuscript.

Five approaches viz., handpicking and killing of lemon butterfly larvae (T 1), spraying of imidacloprid (Sapta 70 WG) @ 0.5 g L-1 of water (T 2), bioneem plus (Azadirachtin 1 EC) @ 1 ml L-1 of water (T 3), spinosad (Tracer 45 SC) @ 1.25 ml L-1 of water (T 4), chlorfenapyr (Proclaim 5 SG) @ 1 g L-1 of water (T 5) and an untreated control (water spray only) (T 6) were evaluated. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Approach with insecticides was applied four times at 20-day intervals. Eight plants were selected and tagged at random to collect leaf infestation data from east, west, north and south canopies of the tagged plants. Leaf infestation (%) of the whole plant was calculated by the mean no. of infestation recorded from east, west, north and south canopies of the plant. The lowest leaf infestation (17.83%) was recorded in plants treated with spinosad (T 4) and chlorfenapyr (T 5). The highest leaf infestation (31.83%) was recorded in untreated control plants. The intermediate leaf infestation (20.85% to 21.33%) was recorded in plants treated with hand picking and killing of lemon butterfly larvae, imidacloprid and bioneem plus. Spinosad and chlorefenapyr treated plants produced the highest fruit yield (1.35 t ha-1) and also gave the highest financial returns in terms of Marginal Benefit Cost Ratio (MBCR) (11.50 : 1.0). The lowest MBCR (7.31 : 1.0) was obtained from plants treated with hand picking and killing of lemon butterfly larvae. The results clearly indicated that spinosad is the most cost-effective as well as environmentally safe management approach for lemon butterfly larvae.

need different type of nutrients which are categories into two groups i.e. macro nutrients and
micro nutrients according to their requirements. These nutrients include Nitrogen (N),
Phosphorous (P), Potassium (K), Calcium (Ca), Zinc (Zn), Iron (Fe), Boron (B), Sulphur (S),
Magnesium (Mg) etc. In the plant body, many nutrients influence biochemical processes as well
as provide resistance against diseases and finally disturb the quality of crops. According to fast
increasing in the world population and the decreasing trend in yields of crop make food safety a
main challenge. That’s why balanced application of nutrients is very important to rise the crop
yield and to attain the necessary increase in the production of food. Furthermore, nutrients play
a significant role in fertility of soil and make it more productive for the growth of plant. This
review article will discuss the recent information that concerning about the nutrients and their
use in sustainable agriculture for the growth of plant.

The study was undertaken in the field of the department of Entomology at Sylhet Agricultural University in 2017-2018. The leaf length and breadth ranged from 7.33 to 8.77 and 7.22 to 12.47 cm, respectively. The varied flower color, pod and cotyledon color and pod curvature observed visually in two experimental field. The highest germination was recorded in BARI sheem 1 (100%) in winter season and SB sheem-003 (100%) in summer season and the lowest was in BARI sheem 6 (72. 22%) in winter season and Sikribi sheem 2 (50%) in summer season. The pod length and breadth and number of green seed pod-1 were ranged from 8.12 to 17.33 cm, 1.33 to 2.69 cm and 4.06 to 5.80 cm, respectively during winter and summer. The infested pod and infested pod weight range from 1.91 to 10.37 % and 1.31 to 11.37 kg plot-1 during winter and summer season. The cumulative leaf and inflorescence infestation were noted and it was ranged from 39.64 to 49.22 and 18.86 to 23.90 % in winter bean and 27.64 to 38.24 and 17.63 to 21.15 % in summer bean, respectively under field condition. The maximum yield observed 6.86 and 4.84 t ha-1 recorded in BARI sheem 1 and Sikribi sheem-1 and minimum yield was recorded in Goalgadda sheem and SB sheem 003 genotypes in two field during winter and summer season. Winter country bean BARI sheem 1 and summer country bean Sikribi sheem-1 showed the highest resistance resulting the highest yield. On the other hand, pests’ resistance of winter and summer country bean (IPSA sheem 2) showed the moderate level of tolerance against insect abundance in country bean. The BARI sheem 1, Sikribi sheem 1 and IPSA sheem 2 varieties showed the rational resistance against the insect community in country bean agro ecosystem.

The results revealed that five pests such as aphid (Aphis gossypii Glov.), jassid (Amrasca biguttula Ishida), flea beetle (Phyllotreta vittula), leaf roller (Sylepta derogata) and one white mite (Tetranychus sp.) were found as the major pests of okra. Genotype JO5 was found as the least susceptible to pest incidence. The number of okra leaf hair (trichome) had significant negative relationships with the number of aphid (R 2 = 0.6136, p<0.05) and jassid (R 2 = 0.4143, p<0.05). Genotype JO7 produced the highest yield (19.31 t ha-1) followed by JO9 (17.40 t ha-1) and JO3 (15.49 t ha-1). Genotype JO5 produced the lowest yield (4.88 t ha-1).The results indicated that JO3, JO7 and JO9 are the three promising genotypes with respect of their higher yield performance. The JO5 genotype could be used in breeding program with higher yielding variety/genotypes to develop new pest resistant and high yielding new okra variety.

including direct effects of drivers on plants, the community response of species abundances to
drivers and the feedback effect of community change on productivity. The productivity of C4
plants is significantly influenced by C4 metabolic process of plants. Apart from these metabolic
pathways, one of the most essential elements that influence the yield of C4 plants are seasonality
and temperature. In addition to all, these climatic climate change drivers have a great influence
on the productivity of C4 plants. The present review focuses on how C4 plants mitigate climate
change.

Chrysanthemum is a floricultural, ornamental and medicinal plant with tremendous income cash crop... more 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.

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.

The different treatments were Bioneem 1% EC (Azadirachtin 1000 ppm @ 1 mL L −1 (T1) Noclaim 5 SG (Emamectin benzoate) @ 1 mL L −1 (T2), Tracer 45 SC (Spinosad) @ 0.4 mL L −1 (T3), Suntec 1.8 EC (Abamectin) @ 1.2 mL L −1 (T4) and untreated control (T5). The results revealed that the treatments Spinosad (T3), Abamectin (T4) and Emamectin benzoate (T2) were effective to suppress brinjal shoot and fruit borer infestation in brinjal field. The rate of shoot infestation was observed 6.25% and 26.01% in Spinosad (T3) treated and control plot, respectively. The lowest fruit infestation (6.98%) by number and (9.32%) by weight was recorded in Spinosad (T3) treated plot. Reduction rate of fruit infestation over control was 82.82, 51.19, 41.15 and 38.17% by number and 66.11, 43.75, 33.13 and 24.44% by weight in Spinosad (T3), Emamectin benzoate (T2), Abamectin (T4) and Azadirachtin (T1), treated plot, respectively. The yield in different treatments ranged between 22.02 and 32.52 t ha −1. Healthy fruits yield increase over control varied from 19.36 to 85.46%, where the highest increase was found in Spinosad (T3) treated plot and the lowest in Azadirachtin (T1). The highest adjusted net return and benefit-cost ratio (BCR) of Tk. 2,61,564 and 11.08, respectively were obtained from Spinosad (T3) treated plot. The lowest BCR was 2.66 in Azadirachtin (T1) treated plot. Among the four bio-rational inecticides Tracer 45 SC (Spinosad) showed the highest efficacy and it could be used against brinjal shoot and fruit borer in brinjal production.

In this situation, most of the farmers meet crises in agriculture sector, so the aim of the study is to analyze and discuss the impact of Covid-19 on agriculture. In lockdown condition, effect on all the sector of agriculture and the farmers say that no one is coming from outside to buy cows and goats and they are not able to sell big cows and goats in Eid, 2020. Even though it is being sold, there are many losses. Despite good yield fruits, the lockdown char coronavirus has also affected local markets in Bangladesh. the findings also indicate that the COVID-19 has had a huge impact on food. Additionally, COVID-19 threatened agriculture even in some developed, whereas developing countries are the most pretentious due to their high dependency in securing their food supplies. Finally, based on the findings, we have suggested some recommendations that would help boosting sustainable agriculture sector.
