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.

The main aim of this review is to document the insect pests and diseases of jackfruit (Artocarpus heterophyllus L.) and their management in Bangladesh compared to other jackfruit growing countries. This article was based on mostly literature review. A. heterophyllus being the national fruit of Bangladesh, is widely consumed by most of the rural people. All parts of the fruit and tree are used as human food, animal feed and wood source for furniture. 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. Despite the importance, a number of insect pests and diseases attack jackfruit plant and fruit. Shoot and fruit borer (Diaphania caesalis Walker) and trunk borer (Batocera rufomaculata De Geer) have been reported as major insect pests, while stem and fruit rot (Rhizopus artocarpi), bacterial dieback, pink disease (Pelliculana salmonicolor), leafspot (Phomopsis artocarpina), fruit bronzing (Pantoea stewartia Smith) and Gummosis (Phomopsis artocarpi) have been reported as major diseases. The pruning and training are an effective management technique for the insect pests and diseases. This technique provides well ventilation and reduces relative humidity at tree canopy level. Bordeaux paste is a common fungicide for the management of jackfruit borer pest and rhizopus rot, leaf spot, dieback and gummosis diseases. This paper has heighted the multifarious benefits of jackfruit plant and described the problems and solutions of jackfruit cultivation in agroforestry system of Bangladesh.

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.

Groundwater quality of Jalalabad cantonment area in Sylhet city is deteriorating. The study was conducted for assessing the ground water quality in drinking purpose of Jalalabad cantonment area in Sylhet city. For human survival, water is a vital resource. Total twenty-five water samples were collected from different parts of Jalalabad Cantonment area from deep aquifer-based tube wells. The collected water samples were analyzed for different physicochemical properties like Color, taste, odor, pH, electrical conductivity (EC), total dissolved solids (TDS), calcium, magnesium, sodium, potassium, boron, sulphur, copper, iron, manganese, and zinc concentrations. All the analyzed parameters compared with the standards prescribed by World Health Organization (WHO) and Bureau of Bangladesh Standard (BBS), in order to assess the ground water quality for drinking purpose. For different parameters of drinking water, the correlation matrix was also calculated. Almost all the physicochemical parameters were found within the prescribed permissible limit. Findings show that some of the parameters Cu and Zn were negatively associated with TDS, Ca2+, Mg2+, S contents.

The study was conducted to evaluate the vermicompost enhances the yield and quality of red amaranth subjected to acidic soil. Five treatments namely, control (T1), cowdung (T2), compost (T3), vermicompost (T4) and lime+100% recommended inorganic fertilizer dose (T5) were considered in acidic soil for the fulfilment of experimental objectives. The experiment was laid out in a randomized complete block design with three replications in the southern part of Bangladesh. All the treatments gave significantly higher yield (p<0.05) while it was compared to the control.  Highest yield of red amaranth was observed from the treatment of vermicompost (7.79 tha-1) followed by lime (5.79 tha-1), compost (5.52 tha-1) and cowdung (4.73 tha-1). The result showed that the effects of vermicompost were more efficient in terms of vigorous production, nutrient contents as well as in the maintenance of soil pH for the potential cultivation of red amaranth compared to the other management. Besides these, the nutrients content of red amaranth was also observed and found that the Ca, Mg, K, P, S and Fe were substantially higher in vermicompost except the Zn and B. Mg, K and P content were highly (r2=>0.9) correlated with the yield. Only vermicompost and lime enhanced 7% and 0.3% of pH over the control. Therefore, in acidic soil the vermicompost would be the best alternative for Red amaranth production.
