Abstract: The present study explored the potential of regional linkage among oil seed producers, retailers, wholesalers, crushers and consumers, with a particular focus on the production, processing and market systems in the major oilseeds production regions, like Thakurgaon, Dinajpur and Tangail districts of Bangladesh. The key stakeholders of soybean include producers (farmers), input suppliers (such as agro-dealers and corporation), assemblers, collectors, wholesalers, processors and exporters. Farmers typically get inputs, like seeds, pesticides and fertilizers from agro-dealers, corporation or fellow farmers. The oil quality is the most important factor for the majority respondents (60), while 58 consumers expressed the brand name as the key indicator of preference. Some consumers opined that both quality and brand are important in selecting cooking oil. Nearly all consumers used a combination of soybean oil and mustard oil, with a few incorporating olive oil and sunflower oil into their diets. The majority oil users consumed approximately one liter per month, followed by those used half a liter. A significant portion of the households consume up to 2 liters per month. In contrast, soybean oil consumption was significantly higher, with many households use more than 5 liters per month. About 61% of the respondents revealed the health benefits as the main reason for choosing mustard oil. Additionally, 20% of the consumers mentioned the organic nature of mustard oil as the key factor of their selection, while many noted that it enhanced the taste of food. The majority of the respondents prioritized the quality of the product above all other factors, including brand preference. While 50% of the respondents preferred to stick to a single brand, relying on the established credibility and quality of the product, the other 50% frequently switched to different brands. Price plays a significant role, as many consumers select a brand on affordability. When selecting of an oil brand, consumers prioritize company reputation. The mustard oil market varied from 270 BDT/liter to 400 BDT/ liter with an average price of 285- 290 BDT/ liter during the study period in 2024. Half of the consumers thought that the mustard oil price is exorbitant to afford for the commoners.

Abstract: The seasonal abundance of mango leaf cutting weevil (Deporaus marginatus Pascoe) was studied on nine varieties of mango viz. Amropali, Harivanga, Mallika, Surjapuri, Gopalvog, Langra, Fazli, Ashwina and Guti during October 2016 to September 2017 in the orchard of Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh. In this study toxicity of some weed extracts namely black nightshade, wild tobacco, leucas, lantana, goatweed and raan tulas were evaluated on the weevil. Rresults showed that the highest percentage of infestation was found in Surjapuri (average 52.6%), and the lowest in Ashwina (average 33.4%). In regards to month, maximum infestation was found in August (77.5%) at surjapuri and minimum was in February (7.9%) at Mallika. No infestation was observed on the mango leaves during December and January. The highest toxicity effect (average mortality 78.3 %) was found in rann tulas at 5.0 % concentration, whereas black nightshade showed the lowest toxicity effect (average mortality 10.8 %) at 1.25 % concentration. On the basis of mortality, the order of toxicity of the plant extracts were found rann tulas > wild tobacco > lantana > goat weed > leucas > black nightshade. Adult’s mortality were directly proportional to different concentration levels and hours after treatments (HAT). The lowest LD50 values (3.3, 2.3 and 1.8 mg/ml at 24, 48 and 72 HAT) of rann tulas indicated its highest toxicity effects against D. marginatus. The present study revealed that synthetic pesticides can be replaced with botanicals for the management of D. marginatus in order to save the environment.

ABSTRACT: Mosquito-borne diseases pose significant health challenges globally, particularly in regions such as Bangladesh where chikungunya and dengue have been prevalent in recent years. These diseases are transmitted through the bites of infected mosquitoes, which breed in stagnant water. Common mosquito-borne diseases include chikungunya, dengue, malaria, and Zika virus, among others. Efforts to control mosquito populations have included the destruction of breeding sites, the application of larvicides, and more recently, the use of Bacillus thuringiensis israelensis (BTI) in Dhaka. While these measures have helped manage chikungunya, dengue remains a persistent issue despite ongoing control efforts. This paper explores innovative mosquito control strategies, focusing on asphyxiation techniques to reduce mosquito populations and the use of homemade repellents for personal protection against mosquito bites. The effectiveness of these methods in the context of dengue management is critically examined.

ABSTRACT: Bangladesh, spanning 148,460 km² with a 580 km coastline, confronts significant climate change challenges, experiencing rising temperatures and declining rainfall. With a population exceeding 170 million, its density could surpass 1200 people per km² by 2025, despite ranking 94th in land area and 8th in global population. Bangladesh ranks 3rd in rice and vegetable production and 10th in tropical fruits production: The country’s pesticide use ranks 29th globally, with substantial variations per hectare compared to leading countries like China and Japan. Pesticides play a vital role in Bangladeshi agriculture to combat pests and diseases. Fluctuations in registered formulations from 2010 to 2022 indicate regulatory adjustments and market shifts, with biopesticide registrations witnessing growth. The pesticide industry has flourished, with the number of companies expected to reach 802 by 2024, reflecting increasing demand and regulatory approvals. However, pesticide consumption has shown fluctuation, with increases in both usage and market value. The heavy treatment of vegetables like brinjal highlights the necessity for targeted pest management strategies. Despite the benefits of pesticides in enhancing yields, their misuse poses significant health and environmental risks, necessitating sustainable pest management practices to ensure long-term agricultural and environmental sustainability in Bangladesh.

ABSTRACT: Drought is one of the most serious environmental stresses that hinders mungbean (Vigna radiata L.) production seriously. Improvement of soil nutrition is one of the effective measures to enhance drought tolerance of upland crops like mungbean. This study was conducted to evaluate the effect of higher levels of macro nutrients on growth and yield performance of mungbean. Recommended dose, and two, three and four folds of the recommended dose of major fertilizers (N-P-K-S) were applied on two popular mungbean varieties namely, Binamoog-5 and BU mug4 under water stress. The effect of the higher levels of fertilizer on stressed plants was evaluated by examining different morphological parameters of growth such as plant height, parameters of growth analyses, yield attributes and grain yield. Water stress in general had a negative effect on plant growth and development. However, the enhanced levels of nutritions lessened the water stress effect. Increased plant height, leaf area, CGR, RGR, NAR, and grain yield and yield attributes were measured in plants that received elevated nutrients. In general Binamoog-5 showed higher water stress tolerance than BU mug4 in relation to the production of grain yield and yield attrbutes. Under water stress the highest number of pods plant-1 was recorded in T4 where Binamoog-5 produced 15.33 plant-1 and BU mug4 had 13.33 plant-1. The highest 100-seed weight was recorded in Binamoog-5 (4.65 g) and BU mug4 had 4.29 g with the three-fold increased doses of N-P-K-S fertilizer (T4 ). The highest grain yield plant-1 was also recorded in T4 where Binamoog-5 produced 4.95 g plant-1 and BUmug4 produced 3.95 g plant-1. It was concluded that higher levels of NPKS enhanced productivity of mungbean, than the recommended.

Abstract: To investigate the effects of intercropping of maize with sugarcane on cane development, outturn, and overall economic return, field experiments were carried out during the cropping year 2021–22 in two different locations: Bangladesh Sugarcrop Research Institute (BSRI), Ishwardi, Pabna and the Regional Sugarcrop Research Station (RSRS), Thakurgaon, Bangladesh. There were nine treatments namely T1 : Single row sugarcane only (SS), T2 : SS+ Maize (During sett placement), T3 : SS+ Maize (7 days after sett placement), T4 : SS+ Maize (14 days after sett placement), T5 : SS+ Maize (21 days after sett placement), T6 : SS+ Maize (28 days after sett placement), T7 : SS+ Maize (35 days after sett placement), T8 : SS+ Maize (42 days after sett placement), T9 : Maize (M) only. Sugarcane variety “Isd 39” and maize variety “Super 92” were used in this experiment as experimental materials. Results indicated that T7 treatment was superior in terms of germination (56.56% at BSRI and 57.33% at Thakurgaon). The treatments T1 (174.33×103 ha-1 and 184.00×103 ha-1) and T7 (162.67×103 ha-1 and 168.00×103 ha-1) consistently exhibited superior tiller production and millable cane yield at both the locations. However, T1 generally resulted in higher cane yield, while T7 demonstrated higher SEY (108.25 t ha-1 at BSRI and 114.79 t ha-1 at Thakurgaon), LER (1.56 at BSRI and 1.52 at Thakurgaon), ATER (1.20 at BSRI and 1.16 at Thakurgaon), gross monetary value (487133 BDT ha-1 at BSRI and 516533 BDTha-1at Thakurgaon), and monetary advantage index (175178 at BSRI and 177542 at Thakurgaon) compared to other treatments. Treatment T2 also showed competitive SEY (105.52 t ha-1 at BSRI and 108.69 t ha-1 at Thakurgaon), LER (1.64 at BSRI and 1.54 at Thakurgaon), ATER (1.13 at BSRI and 1.07 at Thakurgaon), gross monetary value (474867 BDT ha-1at BSRI and 489100 BDT ha-1at Thakurgaon), and monetary advantage index (184942 at BSRI and 173134 at Thakurgaon), indicating its effectiveness in enhancing sugarcane production. Therefore, it maize planted 35 days after sugarcane sett placement (T7 ) or during sugarcane sett placement (T2 ), profitable intercropping system.

ABSTRACT: A field experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur to assess growth and yield of newly released aromatic rice variety (cv. BUdhan 2) under different levels of plant spacing and applied fertilizer. The variety was grown incorporating three fertilizer levels viz. recommended (57- 10-8-7-0.9 kg N-P-K-S-Zn ha-1), 50% higher (114-20-16-14-1.8 kg N-P-K-S-Zn ha-1) and 50% lower (28.5-5-4- 3.5-0.45 kg N-P-K-S-Zn ha-1) than the recommended dose with three plant spacings (20 × 25 cm, 20 × 20 cm and 20 × 15 cm) representing wider, standard and closer plant densities. Results revealed that growth parameters like plant height, leaf area index, dry matter production and crop growth rate were better under the condition of higher fertilizer level with closer plant spacing. Consequently, the highest grain yield (5.18 t ha-1) of the variety was achieved under higher dose of fertilizer at closer plant spacing.

ABSTRACT: Rice weevil, Sitophilus oryzae Lin. (Coleoptera: Curculionidae) is economically significant and known as a ubiquitous pest in Bangladesh as well as throughout the world. In this study, the infestation rate by this pest was assessed throughout the year on twelve common indigenous cereal grains and pulses, namely boiled and nonboiled rice, wheat, barley, maize, felon, pea, grass pea, lentil, chickpea, black gram and mung bean. There were significant differences in the infestation rate among the months and in the susceptibility among grains over the year. The highest percentage of weight loss over the year was found in chickpea (84.56%) and the lowest percentage of weight loss was found in black gram (7.09%). The chronological position of the experimental grains according to their percentages of weight loss was chickpea > wheat > barley > maize > nonboiled rice > pea > boiled rice > grass pea > lentil ≥ mung bean > felon > black gram. The highest infestation occurs at the temperature range of 32-35o C and during the month of April-June.

ABSTRACT: Lying at the tidally active region of the Bengal Delta, the Sundarbans act as a terrestrial carbon sink and play a crucial role in climate change mitigation. However, this forest is underrepresented in term of soil organic carbon research. The purpose of this study was to investigate the Soil Organic Carbon dynamics across various geomorphic units within a small area of mangrove forest ecosystem of Dublar char of Sundarbans. Salinity and pH trends were also examined across geomorphic units to understand their interplay with soil organic carbon dynamics. Soil samples from 25 locations across various geomorphic units were collected and analyzed to determine soil organic carbon, salinity and pH levels. The Walkley-Black wet oxidation method was employed to determine the organic carbon content. Results indicate varying degree of organic carbon concentration across geomorphic units with Highland areas having high level of soil organic carbon concentrations with average concentration level of 2.05%, followed by Creeks with 1.55%. Salinity levels also varied across different geomorphic units with values ranging from 4.8 ppt to 12.7 ppt, with creek area having high level of salinity due to its close proximity to seawater. Fringe forest areas had the highest pH levels with average value of 7.4 and the lowest average pH value (6.86) was observed in Beach areas of the study area. The study holds immense significance in understanding the organic carbon dynamics of mangrove ecosystem in the Sundarbans, providing essential insights for long term climateresilient land management and biodiversity conservation efforts.
