This study was conducted at the tissue culture laboratory in Pakistan. Suckers obtained from the banana cv. Grand Nain to explore the effects of different concentrations of BAP and IAA. After inoculation with Murashige and Skoog (MS) medium supplemented with different concentrations of 6-Benzylaminopurine (BAP) and the Indole-3- acetic acid (IAA) the suckers first turn into the brown after 5-10 days then turned into a green mass-like structure after 30 days. From this mass-like structure shoots and roots were developed. Among the different concentrations, BAP 7.5 mg/l and IAA 0.5 mg/l showed the highest number of shoots 0.75, 2.75 and 6.25 per explant and shows the highest shoot lengths which 1.03 cm, 2.45 cm and 3.40 cm respectively. IAA is essential for only roots proliferation. The roots of different lengths were produced when the concentration of IAA 0.5 mg/l was used and 2.93 cm, 4.63 cm and 5.88 cm roots length produced at 15, 30 and 45 days after occultation respectively. Then these plants were transferred to the greenhouse for hardening acclimatization with the environment, the hardening process took place, and the established plantlets are ready for planting.

The study was conducted for assessing water quality for drinking and irrigation purposes of groundwater sources. Total 50 water samples were collected from different locations of Nachol and Niamatpurupazilla of Chapainawabgonj and Naogaon district in January 2019 and January 2020. Water quality parameters like pH, electrical conductivity (Ec), iron (Fe), manganese (Mn), calcium (Ca), magnesium (Mg), zinc (Zn), copper (Cu), sodium (Na), potassium (K), total hardness (TH), alkalinity, sulphate (SO4), nitrate (NO3), nitrite (NO2), ammonia (NH4), phosphate (PO4), chloride (Cl), dissolved oxygen (DO), and total dissolved solids (TDS) were analyzed in the laboratory. All the analyzed parameters were compared with national and international drinking and irrigation water quality standards to understand the overall groundwater quality status of the study area. The study showed that the water samples of almost all the locations were suitable for consumption and irrigation.

The study was carried out for investigation and analysis of long-term (45 years) monthly rainfall data of Rajshahi from 1975 to 2019 for better selection of crops and agricultural technology in this region of Bangladesh. The rainfall trend was determined using parametric and non-parametric method. Probability analysis of rainfall was performed for estimation of dry, wet, and average year rainfall. The results revealed negative trend of yearly rainfall, but it is statistically insignificant. By non-parametric method, ‘no trend’ was observed for yearly rainfall. Increasing trend of monthly rainfall during March and May and decreasing trend in other months were observed. The rainfall deficit period continued from November to March, and in some instant up to April (rainfall<PET).Total deficit for dry, wet, and average year were found as 488.2 mm, 405.7mm and 426.1mm respectively. By adopting low water-demanding cropping patterns during the deficit period, the withdrawal of groundwater can be minimized.

Two consecutive field experiments were conducted at the Suapur Union of Dhamrai Upazila, Dhaka, is located at 23088´N latitude and 90014´E longitude and AEZ-12, Bangladesh. The purpose of the experiment was to study the combine effect of nitrogen application methods and weed management for maximizing yield and yield components of boro rice (cv.BRRI dhan29).The experiment consisted of four nitrogen management methods and four weed managements. The experiment comprised two factors; Factor A: Nitrogen management (4 levels), N0: No urea (control), N1: Urea super granules-USG (77 kg N ha-1), N2: Prilled urea at recommended dose (150 kg N ha-1) and N3: ½ of the recommended dose (75 kg N   ha-1); Factor B: Weed management (4 levels), W0: No weeding (control), W1: Two hand weeding (20 and 40 DAT), W2: Pre emergence herbicide (Butachor) and W3: Post emergence herbicide (Prityloclor). The experiment was laid out in a randomized complete block design with three replications. Data on different yield components and yield of BRRI dhan29 were recorded. Statistically significant variation was observed for their combined effect. The highest grain yield (6.80 t ha-1) was obtained from the interaction between urea super granules-USG (77 kg N ha-1) and pre emergence herbicide (Butachor), whereas whereas the lowest (3.85 t ha-1) from the interaction between no urea (control) and no weeding (control). From the results of the study it can be concluded that the application of urea super granules-USG (77 kg N ha-1) and pre emergence herbicide (Butachor) condition might be used for obtaining the best performance of BRRI dhan29.

Nowadays most people in advanced countries endangered under adult diseases such as hypertension, diabetes, hyperlipidemia, inflammatory disease, human oxidation, and liver-related diseases. In South Korea also very serious situation for the adults and children by the changing from vegetable food to animal food and changed labor pattern from physical labor to mental labor.

We aim to review Protaetia brevitarsis surensis (PBS)’s beneficial multi-functions on human with research reports and verification of well-known common sense in South Korea, which was commonly known as medicinally very effective in liver related diseases. PBS larvae known as cold body characteristics, so, it more effective to Yang-in(Oriental physical constitution classification method: Warm body which Jinseng, Panax ginseng, not available people) than Um-in(Cool body- Jinseng available people). The functional effects mostly known effective on liver related diseases mainly by oriental clinic and as folk remedies. However, nowadays PBS larvae’s folk remedies and other multi-functions scientifically researched and that results verified by many papers such as whitening of skin therapeutic effects, prevention of breast cancer, inflammatory disease, human oxidation, and liver-related diseases. For the increasing of medicinal effects, advanced fermentation and ethanol extraction methods will be very useful compared to non-fermentation of PBS larvae and water extraction. So, we concluded that PBS could diminish or decreasing the adult diseases and it will be very useful food and medicinal materials simultaneously for the human food and medicine by the advanced extraction methods.
