Influence of supplement application of probiotic liquid manure on growth and yield of Radish (Raphanus sativus)
Abstract
A field experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, from November 2024 to April 2025, to evaluate the influence of probiotic liquid manure (PLM) as a supplement to inorganic fertilizer on the growth and yield of radish (Raphanus sativus L.). The experiment comprised six treatments: T0 (control, no fertilizer), T1 (100% recommended NPK), T2 (75% NPK + PLM), T3 (50% NPK + PLM), T4 (25% NPK + PLM), and T5 (100% organic: PLM only). The single-factor experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Significant differences were observed among treatments for all growth and yield parameters. Among the treatments, T2 (75% NPK + PLM) showed superior performance, producing the highest root length (26.5 cm), root diameter (42.1 mm), leaf number (16.2), single root weight (659.7 g), SPAD value (62.3), and maximum yield per plot (43.5 kg) corresponding to yield per hectare (210.2 t/ha). In contrast, the control (T0) exhibited the lowest values for most parameters, including yield (101.2 t/ha). The study concludes that supplementing 75% of recommended NPK with probiotic liquid manure significantly enhances radish growth and yield, indicating its potential as an eco-friendly and effective alternative in integrated nutrient management.

Salt stress inhibits growth and yield in Mungbean (Vigna radiata L. Wilckzek)
Abstract
In southwestern coastal Bangladesh, the comparative impact of salinity levels and varieties on Mungbean cultivation has been scarcely enumerated. A pot study was carried out at the Forestry Nursery of Forestry and Wood Technology Discipline, Khulna University during February to May, 2023 to identify the effect of varieties and salinity on Mungbean growth and yield. For the study, three Mungbean varieties viz. BARI mung-6, BARI mung-7 and BARI mung-8 were taken for examining under various salinity levels (<2 dS m⁻¹, 3 dS m⁻¹, 5 dS m⁻¹, 7 dS m⁻¹, 9 dS m⁻¹, 11 dS m⁻¹). The study was conducted in a Completely Randomized Design (CRD) and replicated thrice. Data were collected on various plant growth and yield contributing characters and analyzed statistically. Among the plant growth characters, plant height, branch production and leaf number varied widely (p<0.01) due to treatment interactions. In addition, the Mungbean varieties and salinity levels offered a substantial impact on yield and yield contributing characters (p<0.01). The highest pod number (8.00), pod length (7.85 cm), seeds per pod (9.50), harvest index (24.92%) and seed weight (2.17 g) were obtained from BARI Mung-6 with control while the worst in BARI Mung-8 at the extreme salinity. The yield reduction for BARI Mung-6 was recorded ≈ 30% up to 7 dS m⁻¹ of salinity. Seed weight and harvest index were found negatively associated to salinity as revealed by regression analysis. Form the results of our study, it is concluded that BARI Mung-6 in moderate salinity level can perform well and may be a good resource for cultivation in the coastal soil of southwestern Bangladesh.

BJRI-developed Tossa jute (Corchorus olitorius) varieties: agronomic traits, fiber quality, economic significance and future prospect in Bangladesh
Abstract
Tossa jute (Corchorus olitorius), often termed Bangladesh’s “golden fiber,” remains integral to the nation’s agrarian economy, industrial sustainability, and rural livelihoods. This review critically synthesizes advancements in the development, agronomic traits, fiber quality, and socio-economic significance of BJRI-released Tossa jute varieties, while exploring their evolving role in climate-resilient and sustainable agriculture. The Bangladesh Jute Research Institute (BJRI) has spearheaded varietal improvements through conventional breeding, mutation, and hybridization, resulting in high-yielding, disease-resistant cultivars like O-9897, Tossa Pat 5, and Sobuj Sona. These varieties exhibit superior fiber attributes, early maturing traits, and adaptability to diverse agro-ecological zones, making them pivotal to enhancing national productivity and farmer income. The study evaluates the cost structure of Tossa jute cultivation, highlighting its economic viability relative to high-input cash crops (Average total production cost: BDT 32,000–38,000 ha⁻¹). Labor remains the largest expenditure, but moderate input requirements and favorable market returns ensure attractive profitability, especially when integrated into rice–jute cropping systems. Tossa jute’s efficient nutrient acquisition, driven by extensive root systems, mycorrhizal associations, and adaptive physiological traits, is pivotal for sustaining productivity in nutrient-poor soils. Balanced macro- and micronutrient management, combined with innovations in retting techniques, have significantly enhanced fiber yield, quality, and environmental outcomes. Fiber and seed production timelines are critically examined, emphasizing the importance of timely harvesting (110–120 days) for optimal fiber quality and extended field retention for seed production. The review also discusses eco-friendly retting innovations, such as microbial and ribbon retting, which reduce environmental impacts while improving fiber brightness and softness. A key focus is Tossa jute’s agroecological functions, including carbon sequestration, improving soil health, suppressing weeds, and enhancing biodiversity. Cultivation of Tossa jute on flood-prone and marginal lands supports environmental resilience and aligns with global efforts toward low-carbon, circular economies. The crop’s fully biodegradable fibers position it as a strategic alternative to plastics, offering broad industrial applications in textiles, geotextiles, packaging, and bio composites. The review concludes by addressing the market dynamics, trade potential, and policy imperatives necessary to unlock Tossa jute’s full economic and ecological value. Research priorities include advanced breeding, product diversification, and climate-smart cultivation practices, supported by robust institutional frameworks. Thus, Tossa jute emerges as a multifunctional crop capable of advancing Bangladesh’s sustainability goals, industrial competitiveness, and rural development in the context of global environmental challenges.

Multivariate analysis of Rice (Oryza sativa L.) genotypes
Abstract
Rice is a vital crop worldwide, and understanding its genetic diversity is essential for effective breeding programs. This study aims to assess the genetic diversity of rice (Oryza sativa L.) and examine its genotypes using statistical approaches. The experiment was conducted using a randomized complete block design (RCBD) with three replications. Correlation analysis revealed that grain yield was positively correlated with traits such as effective tillers per square meter (r = 0.65), filled grains per panicle (r = 0.57), and thousand-grain weight (r = 0.47). Multiple linear regression analysis revealed that effective tillers per square meter (R = 0.01), filled grains per panicle (R = 0.02), and thousand-grain weight (R = 0.14) significantly contributed to grain yield. Path analysis findings revealed that effective tillers per square meter had the strongest direct effect on yield (0.35), followed by filled grains per panicle (0.31) and thousand-grain weight (0.27), accounting for 63% of the variation. Principal Component Analysis (PCA) revealed that the first three components explained more than 80% of the variance, with PC1 alone explaining 54.11%. Cluster analysis grouped the 22 genotypes into four clusters, with Cluster 1 recording a grain yield of 6.08 t/ha and a higher number of effective tillers (298.47/m²). These findings imply that effective tillers, filled grains per panicle, and thousand-grain weight are essential selection criteria for enhancing rice yields in breeding programs.

Livelihood status of fish retailers in the fish market at Shahjadpur, Sirajganj, Bangladesh
Abstract
A study was conducted in the Shahjadpur Fish Market, Sirajganj, to evaluate the livelihood conditions of fish dealers. A semi-structured questionnaire was used to gather information from 30 randomly chosen fish retailers. The study revealed that most common age group for retailers was 31 to 40 years old (40%) and the least common was over 50 years old (10%). The primary level comprised 43.33% who were the greatest number of fish retailers. Around 13% of the retailers were Hindu, while 87% percent were Muslim. 53.33% of fish retailers belong to large families with 5 to 6 people. Besides retailing fish their trading at 53%, business at 20%, agricultural at 6.67%, fishing at 10%, day labour at 3.33% and fish farming at 6.67%. The study showed that the experience of this occupation was the longest of 4-6 years (36.67%) and the lowest was at 6.67%. It was found that fish retailers selling fish 15-20 kg/day (43.33%) was the highest number and above 30 kg/day was the lowest number. The majority had a tin-shed house, which comprised 46.7%, while only 10% had a building house. It was shown that fish retailers had a fairly good level of sanitary conditions. Furthermore, it was reported that 46% of fish retailers got medical care from the upazila health centre, 43% from the village doctor and 10% from MBBS, respectively. 26.67% fish retailers had refrigerators, where the majority (73.33%) was lack of it. About 90% of the fish retailers had electricity facilities, while 77 % had colour television. Most respondents had a yearly income of more than BDT 70,000-1,00,000 (33%). More institutional, organizational and technical assistance is needed to help them improve their socioeconomic situation and sustainable livelihood status.
