The main focus of this study was to determine and describe the change of socio economic status of the rural women due to their participation in poverty alleviation programme of motivation, awareness, training and implementation (MATI) in the selected areas of Huzurikanda Union of Nakla Upazila under Sherpur district. The study also explored the relationship between 10 selected characteristics of the MATI beneficiary women and their changes in socio-economic status. Data were collected from the sample of randomly selected 100 MATI beneficiary women out of a total of 400 rural women. The data were collected by using interview schedule which contained simple and direct questions and scales. The socio-economic changes of the rural women under MATI was the dependent variable while age, education, husband’s education, family size, working experience of MATI, contact with MATI personnel, training experience, credit received, credit repayment and credit use of the rural women were the independent variables. The socio-economic status was measured by comparing the before’ and ‘after situation of seven change aspects of the women due to joining in MATI. The significance of change was measured by comparing mean differences between ‘before’ and ‘after’ situation in respect of change in seven areas of socio economic condition of rural women. The change of socio-economic status was significant in five selected aspects while in farm size and toilet condition of the women there had no significant indication of change.
Key words: Socio economic, changes, women, beneficiary.

Culex quinquefasciatusis is responsible for biting nuisance and spreading some dreadful diseases among human beings. Hence, to protect the human in search of an alternative natural insecticide, an excellent study was designed to evaluate the larvicidal activities of Phyllanthus emblica, Carica papaya and Brassica napus seed extracts against C. quinquefasciatus Say larvae under laboratory condition. The larvicidal activity of P. emblica seed extracts was evaluated at different concentrations of distilled water (2000-8000 ppm), methanol (1000-3000 ppm), acetone (800-1400 ppm) and 50% ethanol (2500-4500 ppm), and LC50 of the four extracts were 4189.230 ppm, 1724.708 ppm,1030.483 ppm and 3354.829 ppm, respectively. In case of C. papaya seed extract larvicidal activity was checked at concentrations of distilled water (2000-8000 ppm), methanol (700-1500 ppm), acetone (200-400 ppm) and 50% ethanol (1000-2000 ppm) and LC50 were 4559.578 ppm, 1000.561 ppm, 265.929 ppm and 1406.930 ppm for the four extracts, respectively. For B. napus seed extracts larvicidal activity was recorded at concentrations of distilled water (7000-15000 ppm), methanol (1500-3500 ppm), acetone (500-1100 ppm) and 50% ethanol (2500-4500 ppm) and LC50 were 10118.017 ppm, 2146.948 ppm,700.689 ppm, and3180.144 ppm respectively. Relative position of the extracts on the basis of LC50 and relative potency values was acetone > methanol > 50% ethanol > distilled water, and that of the seed was C. papaya > P emblica >B. nigrus.

Saltwater intrusion into freshwater sources has emerged as a critical public health concern in the coastal regions of Bangladesh, with profound implications for adolescent health and well-being. This study investigates the health consequences of coastal water exposure among school-going adolescents in Kalapara Upazila of Patuakhali district-a region highly affected by saline intrusion due to climate change, sea-level rise, and inadequate freshwater infrastructure. A total of 250 adolescents were surveyed using a semi- structured questionnaire to assess the prevalence of waterborne, water-washed, and water-related diseases. The results reveal that a significant proportion of adolescents suffer from waterborne illnesses such as cholera (91.36%), dysentery (87.74%), and typhoid (80.62%). Additionally, high rates of skin-related issues and gastrointestinal disorders were reported. The findings indicate a strong association between water quality and adolescent health in coastal environments. These insights can serve as critical evidence for public health authorities, educators, and policy-makers to design context-specific interventions aimed at ensuring access to safe water and improving hygiene practices. The study underscores the urgency of strengthening water infrastructure and health education to protect vulnerable adolescent populations in coastal Bangladesh.

A field experiment was conducted in the semi-greenhouse at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka 1207, Bangladesh, during October 2019 to March 2020 to improve yield and quality of cherry tomato cultivation through stem pruning in hydroponic culture. The experiment consisted of three level of pruning viz. P0= No pruning; P1 = One time stem pruning and P2 = Two times stem pruning and four different cherry tomato varieties viz. V1= BARI Tomato-11; V2= BARI Tomato-20; V3= Red Star F1 and V4 = SAU Tomato-2. There were 12 treatment combinations and experiment were setup in two factors Completely Randomized Design (CRD) with three replications. For pruning, maximum fruit number per plant (263.33), fruit length (2.45 cm), fruit diameter (2.45 cm), highest single fruit weight (9.31 g), yield plant-1 (2.37 kg) and TSS (9.46 degrees Brix) were obtained from P2 treatment at 60 DAT. Similarly, in case of varieties, maximum fruit number per plant (257.82), fruit length (2.44 cm), diameter (2.01 cm), highest single fruit weight (8.50 g), yield per plant (2.63 kg) and TSS (8.92 degrees Brix) were obtained from V2 treatment at 60 DAT. In combined effect, maximum fruit number per plant (302.77), fruit length (2.60 cm), diameter (2.20 cm), highest single fruit weight (12.42 g), yield per plant (2.98 kg) and TSS (10.53 degrees Brix) were obtained from V2P2 treatment. Among the treatment combination, V2P2 (BARI Tomato-20 variety with two times stem pruning) treatment seemed to be more promising for obtaining higher yield of cherry tomato. Among the treatment combination, V2P2 (BARI Tomato-20 variety with two times stem pruning) treatment seemed to be more promising for obtaining higher yield and quality of cherry tomato.
