The experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka- 1207, Bangladesh, during 2015-2016, to investigate residual effect of raw material of chitosan (CHT) powder on chemical properties of rice growing soils. The field experiment was done using BRRI dhan29. The experiment was laid out in randomized complete block design (RCBD) with four replications. The first experiment was done using four different doses of the raw material of CHT powder with one control. The treatments were as follows: T1= 0.5 t/ha, T2 = 1.0 t/ha, T3 = 2.0 t/ha, T4 = 4.0 t/ha and T5 = 0 t/ha. The second experiment was conducted in the same plot using the following treatments were T1= Residual effect of the raw material of CHT powder @ 0.5 t/ha (applied in the previous experiment) + 2/3rd of recommended N fertilizer, T2 = Residual effect of the raw material of CHT powder @ 1.0 t/ha (applied in the previous experiment) + 2/3rd of recommended N fertilizer, T3 = Residual effect of the raw material of CHT powder @ 2.0 t/ha (applied in the previous experiment) + 2/3rd of recommended N fertilizer, T4 = Residual effect of the raw material of CHT powder @ 4.0 t/ha (applied in the previous experiment) + 2/3rd of recommended N fertilizer and T5 = Residual effect of the raw material of CHT powder @ 0 t/ha + recommended N (control). The total nitrogen content, soil pH, organic carbon and organic matter status in the post-harvest-soils were increased due to the residual effect of the powder in rice growing soils. The maximum value of the pH (7.01), organic carbon content (0.72%), and organic matter content (1.24%) in the post-harvest soils were found in the treatment T4 and lowest values were observed in the control treatment (T5). From the results it could be concluded that some of the chemical properties of rice growing soils were improved due to the residual effect of the raw material of CHT powder. Residual nitrogen value indicates that the raw material of CHT powder has a slow releasing effect of organic nitrogen supplementation in soil. These results suggest that the residual effect of the raw material of CHT powder could play a significant role to improve the sustainable soil health.

Sweet potato leaves are the traditional indigenous vegetables and most economically efficient source of micronutrients in terms of both land required and production costs per unit. This study aimed to compare and identify one variety rich with proximate, microelements and anti-oxidants from three high yielding sweet potato varieties viz. BARI SP-04, BARI SP -11 and BARI SP-12 including one local genotype leaves that helps provide leafy vegetables as well as micronutrients to poor community in lean vegetables production period of Sylhet regions. The tested varieties and genotype showed significant variation in different nutrient contents. In case of proximate composition the highest ether extract was found in BARI SP-11 (7.33% ±0.64 DW) and the lowest in BARI SP-04 variety (3.80% ± 0.42 DW). And the ash contents range was (12.05% ± 0.89 to 16.43% ± 1.02 DW), but the highest was recorded in BARI SP-12 and the lowest in BARI SP-04. In case of crude fiber the highest (19.99% ± 1.06 DW) was found in BARI SP-11 and the lowest (16.73% ± 0.62 DW) in local genotype. The microelements composition result revealed that BARI SP-04 reserved the highest (32.82 ± 4.5 mg 100 g-1) Iron & (2.1± 0.5 mg 100 g-1) Zinc and the lowest (19.40 ± 2.5 mg 100 g-1) Iron and (1.27 ± 0.2 mg 100 g-1) Zn in BARI SP-11 & local genotype respectively. However in case of phenolic compound, the highest 257.00 ± 10.3 mg TAE 100 g-1 DW was found in local genotype followed BARI SP-11 and BARI SP-12 but the lowest amount 218.75 ± 7.8 mg TAE 100g-1 DW was recorded in BARI SP-04. These results revealed that BARI SP-12 leaves reserved average standard proximate, microelements and antioxidant among the studied varieties and genotype. But all varieties leaves except local genotype contained essential nutrients which may favorably well to meet micronutrient deficiency especially lean vegetable production period for poor community in Sylhet region of Bangladesh.

Published: April 2020

The experiment was conducted in the Aman season of 2016, at Bangladesh Rice Research Institute farm under the Agro Ecological Zone (AEZ 28) Modhupur Tract. The CN6 is a high spikelet bearing advanced line of rice but low in spikelet fertility. Micronutrient management was examined to increase its spikelet fertility. Five treatments were used in this experiment. The treatments were as follows: T1= BRRI recommended fertilizer dose + MgO @ 0.05%, T2 = BRRI recommended fertilizer dose + 60 g MoP + 60 g elemental S (80% wp) + 20 g ZnSO4, T3 = BRRI recommended fertilizer dose + Boron @ 5ppm, T4= BRRI recommended fertilizer dose + Copper @ 5ppm) and T5 = BRRI recommended fertilizer dose alone. The experiment was conducted in Randomized Complete Block design with three replications. The results indicated that Treatment T3 (BRRI recommended fertilizer dose + Boron @ 5ppm) produced the more number of grains per panicle with an average of 194 which is higher number of grains per panicle over the control treatment T5 (BRRI recommended fertilization alone). Treatment T4 produced the highest number of 1000- grains weight (17.9 g). However, highest grain yield was recorded in the treatment T4 with an average of 3.94 t ha-1 compare to the control treatment T5 (BRRI recommended fertilization alone). Second highest grain yield (3.70 t ha-1) was found under the treatment T2 followed by T1 (3.57 t ha-1) and T3 (3.57 t ha-1). The lowest grain yield was recorded in the control treatment T5 (BRRI recommended fertilization alone). Taken together, our results suggested that micronutrient management, especially copper and zinc, improved the spikelet fertility of an advanced line CN6 resulting higher yield.

Published: April 2020

The overall agricultural development of Bangladesh is rapidly progressing. The advancement in agricultural attainments is not a problem free venture. Various new problems are being faced by the SAAOs (Sub-Assistant Agriculture Officers) at present. Thus the purpose of this study was to determine the extent of the problems faced by the SAAOs regarding agricultural extension at field level and to explore the relationships between the selected characteristics of the SAAOs and the faced problems. A number of 46 problems of SAAOs were selected as the focus issue (dependent variable). The study was conducted in Batiaghata and Dumuria upazila under Khulna district. Data were collected from randomly selected 53.97% of the SAAOs (34 out of 63) from each upazila, using an interview schedule during July10 to September 25 of 2019. A problem severity index (PSI) was used to make comparison among the 46 selected problems. Spearman’s Rank Order Correlation Coefficient (ρ) was used to ascertain the relationship between the focus issue (ordinal type of data) and personal characteristics of the respondents. In Batiaghata upazila about two-third of the SAAOs (61.5%) had moderate problems where, “slow rate of promotion compares to other govt. job”, “difficulties of getting promotion” and “shortage of manpower” ranked 1st, 2nd and 3rd position, respectively. In Dumuria upazila majority of the SAAOs (71.4%) had moderate problems where, “every block covers large area”, “shortage of manpower” and “difficulties of getting promotion” ranked 1st, 2nd and 3rd position, respectively. Student t-test result (t Stat 0.35; P(T<=t) two-tail 0.73) showed that there is no significant difference between the problems faced by the SAAOs of Dumuria and Batiaghata upazila. There was no significant relationship between extent of problems and selected characteristics in Batiaghata and Dumuria upazila, except job experience of SAAOs had showed a positive significant relationship. The SAAOs are facing various newly emerged problems at present while conducting agricultural extension activities which should be taken under consideration for priority based solution for sustainable agricultural advancement.

Medicinal plants serve as important therapeutic agents as well as valuable raw materials for manufacturing numerous traditional and modern medicines. Aloe vera is a top ranked medicinal plant in Bangladesh. The objective of this study is to investigate the costs, returns and profitability of Aloe vera medicinal plant. The data were collected from the selected farmers of Bogura and Natore districts in Bangladesh during 2018. The total sample size is 123. The study applies the profitability analysis, break-even points and margin of safety percentage techniques. Surveyed farms are found at ranged from 0.01 to 0.41 hectares. Average cost of production per hectare is found at Tk. 876468.80, of which Tk. 647156.40 for operational cost and Tk. 229312.40 for fixed costs accounting for 73.84% and 26.16% of the total cost, respectively. The average yield of Aloe vera is stood at 41487.62 kg per hectare which is sold to two different markets: contract markets and local market. The mean price is estimated at Tk. 32.42 per kg in study area. The gross margin and net margin per hectare are found to be Tk. 698068.02 and Tk. 468755.61, respectively. The breakeven analysis showed that in the case of yield and price, the margin of safety percentage of Aloe vera is -53.48. It is also found at 42.01, 67.15 and 34.85 for variable cost, fixed cost and total cost of Aloe vera production. Therefore, the study noted that the Aloe vera medicinal plant production is profitable in the study area. Farmers have a great opportunity to allocate more land to Aloe vera production, which will make them more profit. Break-even analysis of Aloe vera production resists a large drop of yield and price before incurring a loss, which gives the farmers a comfortable margin of safety and a risk bearing ability.

Published: April 2020

Animal welfare is a relatively new topic and there is a dearth of the report regarding the welfare assessment of dairy cattle in Bangladesh. Therefore, the present study was carried out to assess the effect of floor surface of the dairy sheds on mastitis, skin lesions, cleanliness of body and lameness of lactating cow in smallholders’ production system. To conduct this study, 5 soil type floor, 5 brick paved and 5 concrete floors of small holder dairy units were selected in Sirajgonj district. From each shed, 5 numbers of dairy cows were selected preferably in the first lactation stage. A total 75 milk samples from three different types of the shed were tested for subclinical mastitis using a California mastitis test. The results showed that 40%, 28%, and 32% cows were CMT positive for subclinical mastitis in soil, brick made and concrete type floor, respectively. The prevalence of SCM was not significantly differences among the different types of floor (P>0.05). Cleanliness and hygienic status of the muddy soil type floor were found to be significantly poor in comparison to that of brick made and concrete type floor of dairy farms. The prevalence of skin lesions in different body parts was higher in brick made (62%) and concrete floor sheds (88%) compared to soil bedded (31%) floor. Hair loses in the concrete and brick made floor was significantly higher (P≤0.01) in comparison with the muddy soil floor. The overall prevalence of lameness of the brick made (72%) and concrete type floor was higher (65%) than that of soil bedded shed (48%). There was a significant difference of lameness between soil type and brick made floor of the shed (P>0.05). The study recommends that in order to reduce the high prevalence of subclinical mastitis, skin lesions and lameness in smallholder farmers require to improve floor conditions through regular cleaning of the floor or upgrade to the concrete floor using rubber mat.

Published: April 2020

This study was performed to explore the pulse oximetric evaluation of cardio-respiratory systems along with the determination of body temperature in dogs anaesthetized with xylazine-thiopentone (X-T) and xylazine-ketamine (X-K) combinations during electrosurgery. Six apparently healthy dogs weighed 20 to 25 kg undergoing electrosurgery (bipolar), were divided into two groups: group A (X-T) and group B (X-K). In group A (n=3), dogs were anaesthetized with xylazine @ 1.1 mg/kg body weight (BW) as intramuscular (IM) and thiopentone @ 20 mg/kg BW as intravenous (IV) injections, and in group B (n=3), dogs were anaesthetized with xylazine @ 1.1mg/kg BW IM and ketamine @ 5.5 mg/kg BW IM after premedication with atropine sulphate @ 0.05 mg/kg BW IM. Bipolar electrosurgery for gastrotomy or castration was performed in the dogs. Pulse oximetric monitoring and the evaluation of clinical changes: heart rate, respiratory rate and peripheral blood oxygen saturation (SpO2) were done along with the determination of body temperature before the induction of anaesthesia (control) and thereafter on 10, 20, 30, 40 and 50 minutes postinduction in both groups during electrosurgery. Temperature, heart rate and respiratory rate were altered significantly (P<0.05) during the experimental period in both groups as compared to the control values. SpO2 was decreased significantly (P<0.05) throughout the experiment and returned to the level of initial control value after complete recovery in both groups. These findings revealed that during electrosurgery in dogs the anaesthetic combinations of X-T and X-K exert certain clinical changes in the vital signs (body temperature, heart rate, respiratory rate) and SpO2 which should be carefully considered to take necessary steps for perioperative patient’s safety and recovery.

Published: April 2020

Haematobiochemical changes of ovine (sheep) blood were investigated during preservation and storage with Citrate Phosphate Dextrose Adenine-1 (CPDA-1) and Acid Citrate Dextrose (ACD) for transfusion. Twelve healthy sheep were selected and divided into two equal groups: group X (n=6) and group Y (n=6). Thirty-five ml of blood was collected from each animal and preserved with CPDA-1 in group X and ACD in group Y under 4°C in refrigerator for 28 days. Haematological changes viz., total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC); and biochemical changes viz., total protein (TP) and pH were evaluated immediately after blood collection and thereafter on day-1, day-3, day-7, day-14, day-21 and day-28 for both groups. In ACD preserved blood; TEC, TLC, Hb and PCV decreased significantly (P<0.01) from day-14 onward, whereas in CPDA-1 preserved blood, these parameters decreased significantly (P<0.01) from day-21 onward. Blood preserved in ACD showed significant changes (P<0.01) in MCV, MCH and MCHC respectively from day- 7, day-14 and day-21 onward, whereas blood preserved in CPDA-1 showed no significant changes in the same parameters throughout the experiment. In both groups, no significant changes were noticed in TP but significant changes (P<0.01) were observed in pH with the progression of storage period. These findings elicited that both ACD and CPDA-1 exert certain haematobiochemical changes in stored sheep blood, however, CPDA-1 was more efficient than ACD in terms of maintaining proper levels of TEC, TLC, Hb., PCV, MCV, MCH and MCHC during preservation and storage of sheep blood for transfusion.

Published: April 2020

A study was carried out for a period for four months from January to April 2019 in eight fish farms at Mymensingh region of Bangladesh. The principal objectives were to study the health status of gulsha in four months from eight farms in Mymensingh region as well as month wise pathological changes of various organs of gulsha through clinical and histopathological observations. Clinical signs of fish were reddish lesion and mild injured in different parts of body, abrasion, whitish spots etc. Gills of fish showed more pathological changes than skin, muscle and liver. Histopathologically, gills of all fish species were more affected in Nuha Aqua Farm than other seven fish farms of Mymensingh in January and February. General gill pathology of the fishes was lamellar missing, haemorrhage and hypertrophy. Pathology of skin and muscle of the fishes from different farms included epidermal missing, necrosis, vacuum and loss of muscle. Fat bodies, necrosis, vacuum and haemorrhage were the common pathology of liver in the fishes from sampled farms of Mymensingh. Mainly fat bodies, vacuum and necrosis were found in Sharnalata Agro Fisheries, Relience Aqua Farm, Nuha Aqua Farm and Manju Aqua Farm. On the contrary, haemorrhage and necrosis were noticed in Chan Mia Fish Farm, Fish Seed Multiplication Farm; Maskanda and Setu Hatchery and Aquaculture in Tarakanda. In the months of March and April different organs of gulsha fish like gill, skin, muscle and liver were recorded almost normal structure from sampled fish farms. Fish were found to be affected during colder months of January and February. But, during March and April most of the fish were found normal and healthy. From field and laboratory observations it was revealed that the study area had potentiality for gulsha culture, although necessary measures need to be taken especially during winter season.

This study attempted to find out the determinants of shrimp production and to assess the effects of income from shrimp production on family income inequality in Khulna district of Bangladesh. Forty-five farmers were selected from the Bhanderkote union of Batiaghata Upazila under Khulna District. Among them 15 were small farmers, 22 were medium farmers and 8 were large farmers. Data were collected from May to July 2014 through face to face interview. Ordinary Least Square had been used to find out the determinants of shrimp production. Gini coefficient was measured to see the effects of family income inequality. Expenditure on shrimp fingerling, feed, lime, education, and hired labor were the important determinants and had significant effects on shrimp production. Shrimp farm incomes were equal among all categories of farmers (small, medium and large) and all farmers bear the value of Gini0.31, 0.24, 0.12 and 0.36 respectively. In the case of nonfarm incomes small, large and all farmers were relatively equal (G=0.49, G=0.42, and G=0.44 respectively) where the medium farmers (G=0.55) were relatively unequal.
