“…The composition of land type in the AEZ is 56% high, 18% medium high, 7% medium low, 9% low and 10% homestead and water bodies (FAO, 1988). Characteristically, soil texture is loamy, pH 4.8-5.5 (Kumar et al, 2018). The soils are low (1.0 -1.7%) in organic matter content and fertility (BBS, 2016).…”

Farmers’ existing rice production practices provide key indications of interventions for improving yield in their environments. This study aimed to explore those indications in the Fallow - T. Aman rice - Fallow cropping pattern (CP) under rainfed farming practiced by the farmers in Kapasia, Gazipur. Research method employed one-to-one and face-to face interview of 154 farmers practicing the CP. The average yield of T. Aman was estimated as 3.23 t ha-1, slightly below the national average yield of 3.93 t ha-1, in the range of 1.18 to 5.65 t ha-1. Variety was one of the two broad factors that determined the yield variation. The high yeld potential (HYP) category absolutely preferred the production aim, where Swarna-Ranjit (31.2% by farmer) and BRRI dhan49 (24.7% by farmer) were the dominated varieties where average yields were very close (3.51 and 3.36 t ha-1) for Swarna-Ranjit and BRRI dhan49, respectively). Management was the second factor determining the yield variation within varieties. While both the varieties received similar maximum yield (5.65 t ha-1), Swarna-Ranjit produced the minimum yield of 1.40 t ha-1 and BRRI dhan49 of 1.98 t ha-1. This study did not find a consistent pattern of response of the three measured management components - transplanting time, seedling age and seedling density to yield in either variety. The yield variance of BRRI dhan49 under three management components was higher compared to Swarna-Ranjit. Farmers practiced relatively a wide range of three management combinations to achieve high yield in Swarna-Ranjit, but a narrow range of the three management combinations for BRRI dhan49 to achieve the same level of yield. It is concluded that the variety-specific agronomic management to be the avenue for yield improvements in farmers’ fields. Bangladesh Agron. J. 2022, 25(1): 23-36

“…Mirsharai Upazila boasts a total wetland expanse spanning 7,893.60 hectares, with 1,693. 84 hectares designated for open water capture fisheries and 6,199.76 hectares allocated to culture fisheries. Table 1 provides a comprehensive breakdown of land distribution, highlighting wetland distribution for capture and culture fisheries across various unions and Paurashava.…”

“…An ideal pond depth of 2 meters and a pH level ranging from 6.5 to 8.5 are considered optimal for fish production. Notably, the soil pH value, water quality, and land type, particularly Medium Low Land (MLL) in different unions of Mirsharai, are predominantly suitable for both capture and culture fisheries, aligning with the prerequisites for successful aquaculture practices [84,85].…”

Aims: This study aims to comprehensively assess the fisheries resources in the Mirsharai coastal area of Chattogram district, focusing on their contribution to both local and national economies. The research seeks to identify challenges and vulnerabilities, particularly those arising from climate change, impacting pond owners, fish farmers, hatchery owners, and nursery owners in the region. Study Design: The study adopts a cross-sectional design, employing field surveys and interviews to collect data on fish production, and challenges faced by stakeholders. The cross-sectional approach allows for a holistic understanding of the current state of fisheries resources and their interactions with climatic factors. Place and Duration of Study: The research was conducted in Mirsharai, a coastal upazila of Chattogram district, Bangladesh. The study encompasses data collected during the January to December 2016, providing insights into the dynamics of fish production, and challenges faced by fisheries stakeholders in Mirsharai. Methodology: Field surveys were conducted to gather quantitative data on fish production from both capture and culture fisheries. Additionally, interviews with pond owners, fish farmers, hatchery owners, and nursery owners were conducted to qualitatively assess the impact of challenges faced by fisheries stakeholders in Mirsharai on their operations and economic well-being. The combination of quantitative and qualitative methods ensures a comprehensive analysis. Results: The average fish production in capture fisheries was determined to be 63 kg/ha, while culture fisheries, specifically pond aquaculture, yield an average of 1656 kg/ha. The results highlight the significant impact of challenges faced by fisheries stakeholders in Mirsharai on the local fisheries sector, revealing challenges related to market timing, post-larvae availability, and pricing that affect the economic sustainability of stakeholders. Conclusion: The findings underscore the vulnerability of Mirsharai's fisheries to challenges faced by fisheries stakeholders in Mirsharai, emphasizing economic losses for fish farmers, hatchery owners, and nursery owners. The conclusion calls for urgent adaptive measures and climate-resilient strategies in the fisheries sector to ensure sustainability and viability in the face of evolving climatic conditions. Implication: This study has implications for fisheries management and policy development, emphasizing the need for proactive measures to address climate-induced challenges and sustain the economic well-being of fisheries stakeholders in the Mirsharai coastal area.

“…The pH level is considered good in Manikganj compare to Sylhet because all of the samples from Manikganj District were within the standard limit but in Sylhet some samples were lower than minimum standard, evensome areas were high acidic to high alkaline. Plants roots were unable to absorb nutrients when the pH level is high, and when it is too low, they absorb too much nutrients which causes it to die (Kumar et al, 2019).…”

Bangladesh is an agriculture based economic country formed by sediment deposition from upstream rivers. This riparian country covered with fertile soil that supports agricultural diversification. The study aimed to compare current soil quality of Jamuna-dhaleshwari (Manikganj) and Surma-kushiyara (Sylhet) floodplain physiographic regions to forecast about agricultural productivity. Soil quality was assessed through physical (soil texture and moisture), and chemical (pH, electrical conductivity (EC), salinity, soil nutrients (N, P, K), and organic matter content) indicators. A total of 36 soil samples in three different depths (0-15cm, 15-50cm, 50-100cm) from 12 sites were collected from Manikganj and Sylhet Districts. The average particle size and moisture content ratios of Manikganj: Sylhet were gravels (7.88:5.8), very coarse sand (6.85:8.53), coarse sand (7.45:13.2), medium sand (7.35:14), fine sand (6.12:16.4), very fine sand (24.3:19.9), silt (39.56:20.57), and clay (29.3:32.81), followed by, pH (7.61:6.31), and EC (0.24:0.18), respectively. The result revealed that the soil was bit alkaline for Manikganj, compared to range from alkaline to acidic in Sylhet and non-saline for both areas that was suitable for agriculture. The average concentration of nitrogen (N), phosphorous (P), potassium (K) nutrients in Manikganj and Sylhet Districts were 0.14%, 3.73 meq/100g, 0.07 µg/g; 0.16%, 3.11 meq/100g, 0.08 µg/g and organic matter were 3.65% and 4.7%, respectively. The results of nutrients in both areas indicated that nutrients were very poor but soil organic matter content was sufficient for agricultural activities. The study concluded that soil texture, pH, salinity and organic matter content in both areas were suitable for agricultural purposes, but a significant declined was found in soil moisture and nutrients quality. Finally, it was recommended that soils of Manikganj were more sustainable for agricultural activities.
