The water and nitrogen (N) play a vital role in rice production aimed at high N use efficiency and water saving irrigation. Water saving management might affect the soil condition (oxidized and reduction) and these soil condition affects the fate of N in paddy soil also. We designed three irrigation regimes, conventional irrigation (Flooding), shallow water depth (SWD), and Non-flooding treatment, for our study. The fate of N and growth of rice were not different among treatments during early growth stage by water management. Root activity of rice during middle growth stage was high in SWD and this fact might be affected above ground biomass and so on during middle growth stage of rice. The recovery efficiency, N uptake and above-ground biomass at heading stage were higher in SWD than other two treatments. Despite water stress under Non-flooding water management at vegetative stage, yield did not differ from Flooding and can save much irrigation water during rice growing period.

The study was conducted to know the status of soil fertility at post harvest stage of okra while using household waste and poultry manure. The results showed that the soil pH, organic carbon, CEC, total nitrogen, available phosphorus, exchangeable potassium and available sulphur content in post harvest soil of okra were increased due to application of organic manures as compared to initial soil, which indicated enrichment of soil fertility due to the use of household wastes and poultry manure decomposed for different periods. The treatment with 30 days aged HWN₅₀+ urea N₅₀ recorded the highest percentage of total N (0.12%) in post harvest soil of okra. Whereas the treatment with 30 days aged PMN₅₀+ urea N₅₀ recorded the highest available P (10.79 ppm), the highest exchangeable K (0.66 meq/100g soil) and the highest available S (24.28 ppm). The treatment of 60 PMN₇₅ + urea N₂₅ recorded the highest soil pH (6.22) which was near to neutral in the post-harvest soil of okra. The maximum organic carbon content (1.39%) was recorded in 30 HWN₇₅ + urea N₂₅. The highest CEC of post harvest soils of okra was found in the treatment of 30 HWN₇₅ + urea N₂₅. The densities of soil decreased slightly with the addition of organic manures indicating the improvement of the physical properties of soil. The lowest bulk density (1.44 g cm^-3) at 0-15 cm depth was recorded in the treatments of 60 HWN₅₀ + urea N₅₀, 60 HWN₂₅ + urea N₇₅ and 30 PMN₇₅ + urea N₂₅. The study suggests that the application of poultry manure can supplement a large amount of soil nutrients for the standing crop as well as enrich the soil health providing improved chemical and physical properties.

The increasing food demands of a growing human population and the need for an environmentally friendly strategy for sustainable agricultural development require significant attention when addressing the issue of enhancing crop productivity. Here we discussed the role of integrated nutrient management (INM) in resolving these concerns, which has been proposed as a promising strategy for addressing such challenges. INM has multifaceted potential for the improvement of plant performance and resource efficiency while also enabling the protection of the environment and resource quality. Unbalanced use of chemical fertilizer is a problem in the intensive cropping systems on the Central part of Bangladesh. Proper nutrient management is essential to maximize potato production and sustain agricultural production while minimizing negative impacts on the soil fertility. The aim of the present study was to investigate nutrient dynamics, potato yields and soil fertility in response to balanced fertilization. A field experiment was conducted at the research station of the Tuber Crops Research Sub Centre (TCRSC), Munshiganj during 2012-2013 to evaluate Maximizing potato production through nutrient management. Six treatments viz. T₁= Control, T₂= 100% Recommended Dose, T₃=Poultry manure + Recommended chemical fertilizer, T₄=Cowdung manure + Recommended chemical fertilizer, T₅= Poultry manure + 70% Recommended chemical fertilizer and T₆= Cowdung manur+70% Recommended chemical fertilizer were evaluated for this purpose. The results indicated that the highest tuber yield (36.48 t/ha) was found from T₄= Cowdung manur+ Recommended chemical fertilizer treatment. The lowest tuber yield (7.33 t/ha) was obtained from T₁=Control treatment. Various approaches and perspectives for further development of INM in the near future are also proposed and discussed. Strong and convincing evidence indicates that INM practice could be an innovative and environmentally friendly strategy for sustainable agriculture for developing countries like Bangladesh.

This experiment was conducted to evaluate the qualities of sweetened condensed milk of four different brands (Danish, No.1, Carnation and Goalini plus) available in local markets of Bangladesh. Each brand was considered as treatment and three samples as replications were taken for each brand. Parameters studied in this experiment were physical (flavour, body & texture, colour and taste), chemical (acidity, total solids, carbohydrates, fat, protein and ash) and microbiological (total viable count and coliform count). In case of physical quality, all the four brands possessed the good quality grade and no significant (p>0.05) difference was observed. However, significant differences were revealed in case of total solids, carbohydrates, protein and ash content. On the other hand, insignificant differences were found (p>0.05) in case of acidity and fat content. No coliforms were detected which indicated that good sanitary measures were adopted during the manufacture and storage of the sweetened condensed milk. In conclusion, it can be said that Danish and Goalini plus brands of sweetened condensed milk were found to be better than that of No.1 and Carnation condensed milk.

Early food composition studies were carried out to identify and determine the chemical nature of the principles in foods that affect human health. The study was carried out to determine the composition of various types of food in Barisal city areas from 12 March 2014 to 12  July 2014 to observe whether the composition met the Bangladesh standard or not. In this study, a total of 36 samples, where the number of  biscuit, chilli powder, black tea, cake and white bread were 8, 7, 5, 11 and 5, were collected and analyzed with proper methods in BSTI laboratory, Barisal. It was revealed that, average of moisture, acid insoluble ash, edible fat and acidity of extracted fat of biscuits were 2.698, 0.03, 18.078 and 0.466 and   the average of moisture, acid insoluble ash and acidity of extracted fat o cake were 14.767, 0.019 and 0.462 respectively. In case of chilli powder, the averages of moisture, total ash, acid insoluble ash, crude fibre and nonvolatile were 4.621, 5.3,0.607, 17 and 17 respectively and, the averages of total ash,P^H , acid insoluble ash and  crude fibre of white bread were 65.652, 5.24, 0.03 and 0.16 17 respectively whereas, the average   water extract, water soluble ash of total ash, alkaline of water soluble ash, acid insoluble ash and crude fibre were 34.566, 5.4, 66.02, 0.85, 0.228, and 14.232 respectively. It was observed that, all results were within the range of BD standard and dry hard biscuit contain less moisture that increases the keeping quality and these samples of the study are the low sources of ash but chilli powder were  good sources of crude fiber and total ash. In case of white bread, the moisture contents were high that may make  favorable condition  to grow the different types of organism which reduce the self-life of the product.  The samples of black tea contain higher water extract indicates its better quality.

Arsenic is a major water pollutant that may cause serious health hazards in human and animals. Drinking water is the principal source of arsenic exposure to living individuals. This study was aimed to observe the effects of arsenic on the gross anatomy of testicles in the Black Bengal goat reared at the arsenic prone area in Mymensingh district. Adult male goats were collected from the arsenic prone area of the Ishwarganj Upzilla and arsenic free area of the Nirlakha Char area of Guripur Upzilla of Mymensingh district. Testes were collected for the observation of the effects of arsenic on the gross anatomy of the collected testes of Black Bengal goats. The mean length, width, diameter and weight of the right testes of control group of goats were 5.940 ± 0.044 cm, 3.810 ± 0.041 cm, 9.920 ± 0.015 cm and 36.610 ± 0.068 gm. respectively. The mean length, width, diameter and weight of the right testes of arsenic affected group of goats were 5.880 ± 0.039 cm, 3.770 ± 0.057 cm, 9.920 ± 0.057 cm and 36.540 ± 0.676 gm. respectively. Variations were statistically insignificant (P<0.05). These findings indicate that chronic arsenic exposure does not alter the gross anatomy of testes of Black Bengal goat reared at the arsenic polluted area of the Mymesingh district.

The present study was undertaken to evaluate the medicinal properties of Hibiscus rosasinensis on mice. For the research White Swiss albino mice were orally administered Hibiscus rosasinensis flower (500 mg/kg body weight) and effect of the treatment on the kidney was observed. Crude extract of the Hibiscus rosasinensis possess the potentiality to act against many disorders or diseases which can easily be treated by this plant.  But whether the flower of the plant is detrimental for the kidney or not is yet to be established by the scientists. Through this research, it is suggested that there was no remarkable changes in the kidney. The parenchyma in the treated group was same as the control group without having any inflammation or necrotic degeneration or edema. There was no tubular necrosis in the kidney. But the only thing that was observed here is deposition of the adipose tissue or fat deposition in a portion of the kidney glomeruli of the treated group.

The experiment was conducted to find out the effect of different levels of kalogira extract and synthetic antioxidant on fresh and preserved beef meatballs as source of value added meat products.  Five treatment groups as control group (T₁), BHA (T₂– 0.1%), 0.1%, 0.2% and 0.3% kalogira extract treated as (T₃), (T₄), and (T₅). respectively. Day’s intervals of experiment were on 0, 15^th, 30^th, and 60^th. DM content increased significantly (p<0.05) with advancement of different days intervals. CP, EE and Ash content at different treatment levels differ significantly (p<0.05). FFA values, TBARs, PV were decreased significantly (p<0.05) at different treatment levels. Color, flavor, tenderness, juiciness, overall acceptability, raw p^H, cooked p^H were increased at different treatment levels significantly (p<0.05). Cooking loss (%) with advancement of different days intervals were differ significantly (p<0.05). In microbiological assessment, TCC (log CFU/g) and TYMC (log CFU/g) was decreased significantly (p<0.05) at different treatment comparison to control, Addition of BHA and Kalogira extract significantly reduced aerobic plate count and storage time had negative effect on total bacterial counts and coli form group for all samples. But TVC (log CFU/g) increased significantly with increasing storage period. Hence, it may be concluded that kalogira extract had potential source of antioxidants and antimicrobial activities as similar characteristics of synthetic antioxidant BHA.

An experiment on induced breeding of Anabus testudineus was carried out to determine the optimum dose of Flash hormone at the Reliance Aqua Farm hatchery, Boilor, Mymensingh. The present study consisted of three treatments (T₁, T₂ and T₃) with nine replications of each. Forty five pairs of male and female were selected from the brood rearing ponds and the average body weight of the female and male were 250±20 g and 200±15 g respectively. To observe the effective dose for induced breeding, the females were injected at the rate of 0.30 (T₁), 0.25 (T₂) and 0.20 (T₃) ml Flash/kg body weight and correspondingly the males were administered a dose of 0.13 ml Flash/kg body weight in all treatments. The fertilization rate and hatching rate were determined. Then the hatchlings were reared in aquarium up to 7 days and survival rate was determined. The water temperature was recorded between 26 to 30⁰C during experimentation. Among the three treatments T₃ showed the best result in terms of fertilization rate (79.89%), hatching rate (66.22%) and survival rate (56.20%). The present findings can be used in induced breeding of A. testudineus for the development of hatchery propagation.
