    ASSESSING FARMERS’ PERCEPTIONS AND CARBON SEQUESTRATION POTENTIAL OF CROPLAND AGROFORESTRY IN THE CONTEXT OF CLIMATE CHANGE
    (HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR-5200, BANGLADESH, 2025-06) HOSSEN, MD. FORHAD; Rahman, Prof. Dr. Md. Shoaibur; Hanif, Prof. Dr. Md. Abu
    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.

    COMBINED EFFECTS OF POTASSIUM AND BORON ON THE GROWTH, YIELD AND NUTRIENT CONTENTS OF MUNGBEAN
    (Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University. Dhaka, 2016-06) HOSSEN, MD. FORHAD
    The experiment was conducted at the research plot of the central t'arm of Shcr-e-Bangla Agricultural University. Dhaka during the period from February. 2016 to June. 2016 to study the combined effects of potassium and boron on growth, yield and nutrient contents of mungbean. The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. The experiment was designed with nine different treatment level viz. K0130(0 kg K ha1 a nd 0kg B hi'), K08,(0 kg K hi' and 1.5 kg B hi '), K0132 (0 kg K ha1 a nd 2.5 kg B ha1). K1130(1 5 kg K ha4 and 0kg B hi'). K,B1(15 kg K ha1 a nd 1.5 kg B ha1) K113205 kg K hi' and 2.5 kg B hi'). 1(2[30(25 kg K hi' and 0 kg B hi'). K2131(25 kg K hi'and 1.5 kg B hi') and K 2132(25 kg K ha1and 2.5 kg B hi'). The results indicate that tallest plant(68.47em), highest number of leavcs(23.73), maximum dry matter content(7.75gm). branches per plant(5.37), highest nodule per plant(44), number of pods per plant(2 1.47). number of seeds per pod(9.833). tallest pod(10.10cm). 1000 seed weight(46.97gm), maximum seed yieId(I.87 t hi') and harvest index(46.3 I) obtained from K2132 treatment except days to I' flowering(35.67 days) and stover yield(2.66 t hi'). Lowest values for all of the growth and yield parameters obtained from the treatment K01-30 Results showed that different potassium and boron levels significantly influenced the nutrients contributing characters of munghean. The uptake of nutrient N, P. K and 13 by seed was significantly influenced with the K2132 treatment. The maximum protein and 0-carotene content in seed was recorded in 25 kg K/ha with 2.5 kg B/ha treatment combination. Mungbean growth yield and nutrient contents was increased with increasing the K and B levels.
