“…The organic matter content of the coastal soils is very low (1.0-1.5%). N and P nutrient deficiencies are common in saline soils (Karim et al, 1990). Furthermore, significant saline intrusion may result in zero agricultural yields, resulting in a food catastrophe (Miah, 2014).…”

Salinity intrusion is a major problem, particularly in the coastal area of Bangladesh. This review aims to know the development, present scenario, causes, detection technique, impact and management of salinity intrusion in Bangladesh to assess the salinity chain. Salinity has numerous direct and indirect impacts like hypertension, eclampsia and diarrhoea in humans derived from drinking water, crops, livestock and fish from the affected areas. Salinity affects human life, livelihood, health and well-being and is also closely linked with ecosystems that hamper food production. By decreasing crop, livestock and fish yield, salinity intrusion continuously leads the nation to food insecurity. To overcome salinity intrusion, some management ways are also discussed here.

“…Maize was a great combination of low production cost, high market demand, and high yield, which has generated great interest in maize cultivation among farmers. It is gaining popularity daily in the country due to vast demand, particularly for the poultry industry (Karim et al, 2018). Farmers were shifting to maize cultivation from rice and wheat due to the low cost of production, higher profitability, high demand in the poultry industry, and less risk-averse crops (Kausar and Alam, 2016).…”

The study was undertaken to assess the input used pattern and profitability of maize in selected intensive maize-growing areas of Bangladesh from February to July 2019. The present study was conducted in four districts viz. Chuadanga, Jhenaidah, Meherpur and Kushtia were located at AEZ-11, an intensive maize-growing area. In this study, 160 farmers were selected, of which 40 from each district were randomly selected for data collection. The average farm size was 0.64 ha, whereas the maize cultivated area was 0.34 ha. It was observed that maize was cultivated from November to December in the study area. The average per hectare seed required was 20 kg ha-1 and the fertilizer requirement was 1532 kg ha-1. The average labor required was 275 man-days in a season due to less use of technology. Total production cost was Tk. 162047 ha-1, in which variable cost was Tk. 101066 ha-1 (62%) and the fixed cost was Tk. 60980 ha-1 (38%). The price of the main maize grain at Farmgate was Tk. 18 kg-1. The gross margin was Tk.1 91962 ha-1 and the net margin was Tk. 40515 ha-1 average. The benefit-cost ratio on a cash-cost basis was 1.90 and on a total-cost basis was 1.18, meaning maize cultivation was profitable. Land preparation, seed, organic manure, TSP, Urea, MoP, DAP, Gypsum, Zinc and Boron had a positive influence on maize production. The high price of fertilizer and seed was the main problem farmers faced and due to high demand, there were no marketing problems. Though it had some problems, maize cultivation overall was a profitable crop. Int. J. Agril. Res. Innov. Tech. 13(2): 70-78, Dec 2023

“…The lands remained fallow due to high soil and water salinity and lack of good-quality irrigation water. Agricultural production remained low, and this brought extensive pressure on food security, as more than 30% of the cultivable lands of Bangladesh are situated in the coastal zone [24,25]. Eventually, the water master plan of 1964 was prepared to introduce the polder system in the coastal tidal areas to reduce the people's suffering [19].…”

“…The deposited sediment rich in nutrients improves the soil fertility and increases the potential for crop production [38,45,46], but in some areas, salinization affects the metabolism of the organisms present in the soil and drastically reduces the soil fertility [47]. Widespread nutrient deficiencies in N, P, Zn, and Cu were also observed in many areas of the coastal regions [25,48].…”

The tidal river management (TRM) in coastal areas of Bangladesh has been successful in varying degrees. Though there are many studies on the social, institutional, hydrological and hydraulic factors in relation to TRM, there is no study that investigated the relationship between the water and soil qualities and the TRM success. This paper investigates the variations of water and deposited sediment qualities vis-à-vis the TRM success in selected tidal basins in the southwest coastal delta of Bangladesh. The basins were selected based on the level of success in TRM operation: Beel Bhaina (a successful TRM), East Beel Khuksia (a partially successful TRM), and Beel Pakhimara (an unsuccessful TRM). The level of success in TRM was decided from the local community’s perception and how the TRM operation reduced the drainage congestion and increased the sedimentation depth inside a tidal basin. Fifteen water quality parameters with seven indices and eight soil quality parameters were analyzed to evaluate their suitability for agricultural purposes. The analysis reveals that the water of Beel Bhaina and East Beel Khuksia has high salinity, TDS, TSS, SAR and Na% than that of Beel Pakhimara due to the presence of an active tidal current. The most dominant cation is Na+ in almost all the water samples due to the seawater influence. The most dominant anion is Cl− in Beel Bhaina and East Beel Khuksia, and HCO3− in Beel Pakhimara. The deposited sediment quality parameters are worse in the dry season than in the monsoon, except for organic matter. The soil EC of Beel Bhaina and East Beel Khuksia is low, which may be one of the reasons for good yield in these basins. The average yields of boro rice were 7.2, 7.7 and 6.4 ton/ha in Beel Bhaina, East Beel Khuksia and Beel Pakhimara, respectively, which might be related to the quality of the deposited sediment in the tidal basins and also to the level of TRM success.
