FORHAD Agroforestry serves as a vital strategy for enhancing climate resilience, conserving biodiversity, and sustaining rural livelihoods in northern Bangladesh. This study aimed to evaluate farmers‘ perceptions of climate change, the role of agroforestry practices in mitigating its impacts, and the contribution of cropland agroforestry to carbon sequestration. The research was conducted from February to May 2025 in five villages of Sundorpur Union under Kaharole Upazila, Dinajpur district. A total of 63 cropland agroforestry farms covering 2.52 hectares were randomly selected. Semi-structured interviews captured demographic and socioeconomic data, while biophysical data were collected from 20 m × 20 m quadrats. Findings revealed that farmers were experiencing climate-related stresses such as drought, rising temperatures, and irregular rainfall. Consequently, 71.43% reported increased irrigation demand, 52.4% cited rising input costs, and 30.16% experienced reduced crop yields due to climate change. Biophysical assessments recorded 13 woody perennial species comprising 715 individual trees. Areca catechu showed the highest Importance Value Index (IVI) at 69.08%, followed by Eucalyptus camaldulensis (56.12%) and Swietenia macrophylla (50.79%). Biodiversity indices indicated moderate diversity, with a Shannon–Wiener index of 1.84 and Margalef‘s richness index of 1.521. Swietenia macrophylla had the highest basal area (10.6 m²/ha), while Areca catechu had the highest stand density (104.37 individuals/ha). Eucalyptus camaldulensis contributed most to above-ground biomass (52.27 Mg ha⁻ ¹), followed by Swietenia macrophylla (23.89 Mg ha⁻ ¹). The total woody biomass was estimated at 133.00 Mg ha⁻ ¹, with a total carbon stock of 66.50 Mg C ha⁻ ¹. Despite these benefits, adoption of cropland agroforestry is limited by inadequate training, weak institutional support, and resource competition. Nevertheless, farmers recognized its potential in climate adaptation and ecosystem enhancement, highlighting the need for targeted policy support, capacity building, and continued research to strengthen its adoption under changing climatic conditions.

A total of 38 farmers practicing mango-based agroforestry were selected through a multi-stage random sampling procedure. Data were collected using a structured interview schedule and analyzed using descriptive statistics (frequency, percentage, mean, standard deviation, range). The findings revealed that most respondent farmers were middle-aged (mean 42.5 years) with primary to secondary level education. The average family size was 6 persons, and the mean farm size was 1.5 hectares, with significant portions dedicated to own cultivation and homestead agroforestry. Annual family income averaged BDT 350,000, predominantly from agricultural sources. Farmers exhibited a generally high level of agroforestry knowledge (mean 3.05 on a 4-point scale). Regarding adoption, the average area under mango based agroforestry was 0.75 hectares, with a mean practice duration of 8 years, indicating sustained engagement. Adoption of improved mango varieties and air layering was rapid and widespread. However, the use of hormones and mulching showed polarized adoption patterns, with half of the farmers not adopting these practices or adopting them significantly later. Intercropping, a core practice, showed a phased but substantial adoption. Economic analysis indicated an average material cost of BDT 85,000 per hectare, with fertilizers and pesticides forming the largest share. Farmers generally held positive attitudes towards the profitability and long-term returns of mango-based agroforestry, while perceiving its complexity and maintenance costs as manageable. Key problems identified included "Lack of proper training facility," "Lack of skilled labor," "Disease infestation," "Problems of irrigation in dry season," "High price of fertilizer," and "Lack of improved seedlings," all reported by over 70% of respondents. "Litter fall" was also a concern for half the farmers. Farmers primarily relied on direct human contact (SAAO, model owners, neighbors) and "Watching TV Programmes" for agricultural information. Printed materials and NGOs had significantly limited reach. The study concludes that mango based agroforestry is a well-established and economically attractive system in the region, sustained by a knowledgeable farming community. However, its full potential is hindered by persistent challenges related to technical knowledge gaps, labor, and specific inputs, coupled with underutilized formal extension channels. Recommendations include strengthening agroforestry-specific training programs, addressing skilled labor shortages, enhancing access to quality inputs, improving marketing infrastructure, promoting community-based solutions for animal grazing, and diversifying extension media channels, particularly leveraging digital platforms. These interventions are crucial for fostering a more resilient, productive, and economically viable mango-based agroforestry sector in Dinajpur District.

The experiment was laid out in a 2-factor randomized complete block design (RCBD) with three replications. Factor A consisted of four nitrogen levels, N1 (0 kg/ha), N2 (50 kg/ha), N3 (100 kg/ha) and N4 (150 kg/ha), whilst factor B had three production system, S1 (Napier sole cropping), S2 (Neem + Napier) and S3 (Mahagoni + Napier). Results demonstrated that nitrogen fertilization and agroforestry systems had a significant effect on plant height, collar diameter, number of tillers, leaf traits (length, breadth and number of leaves), green forage yield and dry matter content. Nitrogen application had a significant positive effect on vegetative growth and forage yield, with 150 kgN/ha producing significantly more forage during the growing season. Napier grass grown as sole cropping produced greater than tree based systems due to low competition. Neem surprised by supporting moderate growth with additional soil benefits, while Mahagoni trees reduced Napier performance due to shading and resource competition. Interaction effects were not statistically different in most instances but indicated that in the production systems, tree-based systems (N2S3 and N3S2) potentially demonstrated considerable growth, tillering and leaves with intermediate N levels (50-100 kg/ha). The implications of this are that site-specific nutrient inputs and management should be taken into account. Dry matter was less susceptible to nitrogen, although DM did vary within systems with sole cropping producing the highest DM content. The study underscores the potential of integrating optimized nitrogen management with suitable agroforestry components to sustainably enhance Napier fodder production.

HASINA A field experiment was conducted at the research field of the Department of Agroforestry and Environment, Hajee Mohammad Danesh Science and Technology University, Dinajpur, from February, 2024 to June, 2024 to evaluate the impact of poultry litter on the growth and yield of chili (Bijli Plus) production under mango-based agroforestry system. The experiment was designed as Randomized Complete Block Design (RCBD) with three replications and four treatments of poultry litter at 10 ton/ha, 7.5 ton/ha, 5 ton/ha, and a control with no poultry litter. Each of the 12 plots measured 2m x 2m. Healthy 25-day-old chili seedlings were collected from the Nursery of BRAC, Dinajpur and transplanted in the present research field on February 20, 2024. Data on various growth and yield parameters were collected at 15, 30, and 45 days after transplanting (DAT), including plant height, number of leaves, leaf dimensions, number of branches, chlorophyll content, soil parameters, fruit weight, fruit length, fruit diameter, number of fruits per plant, yield per plot and hectare, and Benefit-Cost Ratio (BCR). The data were analyzed using ANOVA and mean differences were evaluated by Tukey HSD test by the statistical software STAR (Statistical Tool for Agricultural Research). Results indicated that the tallest plants and highest leaf numbers were observed in the 10 ton/ha poultry litter treatment across all stages. Leaf dimensions were also greatest in the 10 ton/ha treatment. But the highest yields per plot and hectare were achieved with 7.5 ton/ha poultry litter, with a maximum yield of 10265.83 kg/ha. The best fruit quality, in terms of weight, length, and diameter, was found in the 7.5 t/ha treatment. The highest chlorophyll contents were in the 7.5 ton/ha treatment. Soil parameters improved post-harvest in all poultry litter treatments, with the most significant improvements in the 10 ton/ha treatment. The highest BCR (3.25) was recorded for the 7.5 ton/ha treatment, while the lowest (2.43) was in the control. In conclusion, the application of 7.5 ton/ha poultry litter is recommended for maximizing chili fruit quality, yield and economic returns under mango-based agroforestry system. This study demonstrates the benefits of using poultry litter to improve chili production in agroforestry systems.
