TUHFA, SIRAJUM MOONIRA From November 2020 to January 2021, the experiment was done at Sher-e-Bangla Agricultural University's Agroforestry experimental area to determine the impact of salt on morphophysiological and yield contributing features of indian spinach (Basella alba L.). The experimental treatments were considered six different levels of salinity viz. S 0 = no salt (control), S 1 = 25 mM, S 2 = 50 mM, S 3 = 75 mM, S 4 = 100 mM and S 5 = 150 mM NaCl. Planting material was selected from the varieties BARI Puishak 1 (Chitra) and BARI Puishak 2. With three replications, the experiment was set up using a Completely Randomized Design (CRD). The tallest plant (106.91 cm), the most branches per plant (13.51), the longest leaf (10.62 cm), the widest leaf (8.42 cm), the largest leaf area (85.54 cm 2 ), the number of leaves per plant (40.83), and the largest plant diameter (1.59 cm). The S0 or controlled condition had the highest SPAD value (74.83), maximum germination (77.76%), plant fresh weight (417.18 gm), highest plant dry weight (60.36 gm), and largest dry matter (14.40 %), while the S 5 (150 mM NaCl) treatment had the lowest value. S 5 or 150 ds/m salt had the highest moisture content (88.87 %). From S 0 to S 5 , the highest to lowest value gradually reduced. Finally, it can be stated that from S 0 to S 5 , cultivating under saline water (100 mM NaCl) treatment resulted in a drop in yield. As a result, the cultivar may be grown in the southern portion of Bangladesh, where saline levels can reach 100 mM NaCl.

The decreasing of sedimentation is causing decline in soil productivity and crop yield which results in severe degradation of environment. Any sediment management strategy performed in this system becomes an intrinsic part of this complex system, according to the goal of our research. This study was conducted at Dacope upazilla under Khulna district. This location was chosen since it is one of the most sediment-prone places. Primary and secondary data were gathered for the investigation. Soil samples were taken from three locations in Dacope upazilla: Dhaki, Vodra, and Chunkuri, using a random sampling approach at 2-3 cm depth. The sediment pH of Dacope upazilla is higher which expresses moderately alkaline (8.12, 8.13 and 8.09). Electrical Conductivity of all these sediments varies from 548.00 to 678.00 µs cm -1 expressing moderate to high salinity. The organic matter content is pretty low to medium (1.10 to 2.64 %) in Dhaki, Vodra and Chunkuri river. The highest OM (%) were found in the flow time of Vodra, khalside of Dhaki and ebb time of Chunkuri are 1.87, 2.64, 1.65, respectively and the variation was significant. The Organic carbon were (1.95, 1.69 and 1.97 %) in medium to low level. Nutrient deficiencies for total nitrogen were quite dominant in the study area (0.25, 0.34 and 0.20 %). Total Phosporus were (38.00, 36.80 and 34.30 ppm) and Sulfur contents were (36.54, 32.50 and 32.53 ppm) in medium level. The study's findings suggest that the severity of the sedimentation problem in the studied locations is worsening by the day. Depending on the pH, OM, OC, and other factors, it has an impact on crops and vegetation. The study offers implying essential management plan to implement correct policy based on the detection of sedimentation status in the studied region and a long-term decision-making approach in the Dacope upazilla of Khulna district.

HASAN Coal mining contamination poses an immense risk to the environment and underlying soil. The main objective of this research was to determine the consistency and deviation of soil quality around Barapukuria coal mine in Parbatipur, Dinajpur. Soil samples were collected from five different locations based on the Regional Land and Soil Resources Utilization Guide of SRDI during summer in 2019. Each sample was separated for the measurement of 12 chemical properties including pH, Organic Matter (OM), Nitrogen (N), available Phosphorus (P), exchangeable Potassium (K), available Sulfur (S), exchangeable Calcium (Ca), exchangeable Magnesium (Mg), Copper (Cu), Iron (Fe), Manganese (Mn) and Zinc (Zn). Nitrogen (N), exchangeable Potassium (K), available Phosphorus (P) and available Sulfur (S) were determined by modified micro Kjeldahl method, Ammonium acetate method, stannous chloride method, and Ion Chromatography, respectively. On the other hand, Cu, Fe, Mn and Zn were determined by DTPA-extraction method at a soil DTPA ratio of 1:2 using Atomic Absorption Spectrophotometer. Data were analyzed by using MS Excel and SPSS software. Results indicated that many of the soil nutrient levels increased in 2019 in comparison with 1999 such as pH (5.28 to 5.70), OM (2.16 to 3.21%), N (0.047 to 0.067 ppm), K (0.41 to 4.12 meq 100g-1), S (16.75 to 31.17 ppm), Mg (1.62 to 6.73 meq 100g-1), Fe (202.67 to 303.50 ppm), Mn (13.11 to 27.40 ppm) and Zn (13.11 to 27.40 ppm). With the increase of time, the average content of Ca (4.15 to 5.74 meq 100g-1) and Cu (0.13 to 0.46 ppm) were decreased whereas the available P did not change much. From the analysis of soil samples it has been identified that several important chemical parameters that is necessary for agriculture are deviated from the Standard Reference value. It is due to the poor infrastructure of coal stock pile and improper disposal of mine water. The findings of this research help us to assess the level of soil contamination in the region of the Barapukuria coal mine.

The experiment was laid out in Completely Randomized Design (CRD) having single factors with four replications. There were 16 unit plots in the experiment location. The high yielding variety of BARI developed vegetables seed of bottle gourd, okra, pumpkin and the seedlings of cabbage, cauliflower, tomato, chili and eggplant were collected from Bangladesh Agricultural Research Institute (BARI). Plant height, stem diameter, number of leaves per plant, fruit length, fruit breadth, fruit weight of different vegetables in rooftop garden were significantly affected due to different locations in Dhaka city. Among the locations, per hectare production of cabbage was highest in Mohammadpur (34.50 ton/ha), highest amount of cauliflower production (40.70 ton/ha) was observed in Adabor. On the other hand, in case of per hectare tomato production, highest amount of yield was recorded in Mohammadpur (95.17 ton/ha). Similarly, per hectare chilli production was highest in Kolabagan (6.80 ton/ha). Highest amount of eggplant production was found in Mohammadpur (13.82 ton/ha). In case of okra, highest fruit weight per hectare (13.89 ton) was observed in Mohammadpur. Similarly, in case of bottle gourd, the highest fruit weight per hectare (61.85 ton) was observed from Dhanmondi. Besides this, the highest amount of pumpkin production (24.61 ton/ha) was also found in Dhanmondi. From the study, it is revealed that different locations have the potentiality to influence the yield of vegetables in the Dhaka city context as well as to increase total production per unit area of rooftop garden.
