Effect of Cropping System and Rice Residue Retention on Crop Productivity and Soil Physical Properties in Rice Based Cropping System of Bangladesh
Authors: Alam M Jahangir , Ahmed S , Islam MK , Islam R , Islam M 
Published: January 2020

Cropping systems of Bangladesh are highly diverse and cultivation costs of puddled transplanted rice (PTR) are high. Therefore, an improved system is needed to address the issues, a field experiment was conducted during 2011-2013 to evaluate system intensification with varying degrees of cropping systems and residue retention. Four cropping systems (CSE) namely CSE1: T. boro rice-T. aman rice (control), CSE2: wheat-mungbean-T. aman rice (wheat and mungbean sown using a power tiller-operated seeder (PTOS) with full tillage in a single pass; puddled transplanted aman), CSE3: wheat-mungbean-dry seeded DS aman rice (DSR), and CSE4: wheat-mungbean-DS aman rice (all sown by PTOS with strip tillage) were compared. Two levels of aman rice residue retention (removed; partial retention i.e. 40 cm of standing stubble) were compared in sub plots. Grain yield was significantly higher (by 11%) when wheat was grown after DSR than PTR. Similarly, PTR and DSR (aman rice) produced statistically similar crop yields. Rice residue retention resulted a significantly higher (by 10%) wheat yield and a slightly increased (by 6%) mungbean yield than that of residues removed. The system productivity of CSE4 was significantly higher (by 10%) than CSE1 when averaged of the two years data. Partial aman residue retention gave significantly higher system yield than residue removal (by 0.6 t ha-1). After two years, no effect of CSE or partial aman residue retention was found on soil physical property (bulk density) of the top soil. Therefore, CSE4 along with residue retention would be more effective for sustainable crop production.

Published: January 2020

This study estimated the cost and revenue of BRRI dhan 28 productions in two districts namely, Bogura and Gaibandha in Bangladesh. The paper also identifies farmers marketing activity and their production problems. Primary data were collected from 60 farm household’s survey using pretested semi-structured questionnaire during November to December, 2017. Farm level production and profitability were analysed by using net farm incomes and Benefit Cost Ratio (BCR) taking into account the variable cost and total cost. Applying descriptive statistics, the analysis showed that total cost of paddy production was higher in Bogura (BDT 44,555.3/acre) compared that of Gaibandha (BDT 42,199.5/acre) while net farm income was higher in Gaibandha (BDT 32992.2/acre) than Bogura (BDT 32475.9/acre). The analysis further showed that paddy production was profitable in both districts. BCR on the basis of variable cost and total cost indicated that return from paddy production was higher than cost which also ensures farmers profit in paddy production in both the districts. According to farmers’ opinion, disease infestation was the major production problem in Bogura district while both disease attack and natural calamities were the major production problems in Gaibandha district. Farmers’ suggested to reduce the cost of pesticides and they need marketing facilities to sell their product. They also suggested to establish cold storage facilities which create the opportunity to get fair price for their product.

Published: January 2020

An experiment was conducted at the growth chamber of Department of Crop Botany in the Bangladesh Agricultural University, Mymensingh, Bangladesh during March 2018 to observe morpho-physiology and anatomical response of sorghum. Six genotypes were grown in hydroponics with a full nutrient solution (NH4NO3-500 μM; Ca(NO3)2-500 μM; MgSO4-200 μM; KH2P04 -100 μM; FeC13-2μM; H2B03-11 μM; MnC12-2μM; ZnC12-0.35μM; CuCl2-0.2μM; (NH4)6Mo704-0.1 μM) and 100 mM salinity was imposed on 14 days seedlings. Data on morpho-physiological and anatomical parameters from seedlings were collected after 21 days and stress tolerant indexes of shoot and root were analyzed. Anatomical parameters like metaxylem and protoxylem thickness were also investigated. The results indicated that all the parameters viz. root length, shoot length, fresh and dry weight of shoot and root, stress tolerance index of root, and shoot, dry weight of shoot and root, relative chlorophyll content, photochemical efficiency (Fv/Fm), proline concentration, total root area, vascular cylinder area and root diameter were decreased with increasing salinity levels except leaf proline content. Genotypes BD 750 and BD 686 showed better performance considering tolerant indicators while the poor performance was exhibited by BD 747 and BD 753. Thus, based on overall observation BD 750 and BD 686 might be salt tolerant.

Published: January 2020

An experiment was conducted at the farmer’s field in Shibalaya upazilla of Manikganj district during rabi season of 2017to study the effectiveness of biochar on soil fertility and yields of brinjal and cauliflower. There were five treatments viz. control, recommended inorganic fertilizer (RF), biochar 1 t/ha + RF, biochar 3 t/ha + RF and biochar 5 t/ha + RF laid out in a randomized complete block design with four replications. Data revealed that biochar at the rate of 5 t/ha along with RF provided maximum yields of brinjal (67 t/ha) and cauliflower (42 t/ha). The pH, nutrients and moisture contents of the study soils increased and bulk density decreased with the higher rates of biochar application. Significant changes were observed in the total organic carbon in soils which increased by 25 to 41% from the initial levels. Recovery, agronomic and physiological efficiencies of N, P, K and S were found the highest with the application of biochar 5 t/ha. In terms of soil fertility and crop productivity application of biochar was found promising and can be recommended as an effective soil management practice.

Authors: Nabil Malek Ahmed , A.K. Salama Ayyad Mohamed , Elkhayat Hussein , El-Minshawy Ahmed 
Published: January 2020

Background: Concomitant aortic root enlargement (ARE) increases the risk of aortic valve replacement (AVR). The objectives of this study were to identify the patients who needed aortic root enlargement and compare the outcomes and the risk of adding ARE to AVR.
Methods: We retrospectively reviewed 62 patients who underwent isolated mechanical aortic valve replacement between 2017 and 2019. We divided the patients into two groups: group A included patients with small aortic root who had AVR with one of the different surgical strategies for small aortic annulus (n= 32) and group B, which included patients with a normal aortic annulus and underwent conventional AVR (n= 30). Group A was further sub-divided based on the surgical strategy into 4 categories; patients who had supra-annular implantation of size 19 mm St. Jude prosthetic valve (n= 11; 34.4%), Nicks procedure (n= 13 40.6%), Manougian procedure (n= 4; 12.5%), Konno procedure (n= 4; 12.5%).
Results: Group A patients were significantly younger (26.16 ± 11.49 vs. 34.63 ± 8.9 years; p< 0.001) and had lower body weight (55.09 ± 21.41 vs. 69.80 ± 19.20; p= 0.01). Group A had significantly smaller valves (p = 0.03), and total cardiopulmonary bypass (148.65 ± 44.09 vs. 97.46 ± 20.90 minutes; p<0.001) and aortic cross-clamp times (118.13 ± 36.70 vs. 78.06 ± 16.01 minutes; p < 0.001) were significantly longer in group A. There was no significant difference in operative complications between groups. Among patients with small aortic root; Konno procedure had the longest bypass time (236.3 ± 19.70 minutes; p<0.001); cross-clamp time (192.5 ± 22.2 minutes; p <0.001); mechanical ventilation (4.75 ± 0.50 hours; p<0.001) and intensive care unit stay (6.50 ± 0.57 days; p <0.001). Patients with supra-annular implantation of the St. Jude valve had a significantly higher postoperative pressure gradient (14.64 ± 6.84 mmHg; p= 0.02). No difference in procedure complications was observed among aortic root enlargement procedures.
Conclusion: Patients who had aortic root enlargement procedure were younger, with lower weight and body surface area. Surgical procedures used to manage small aortic root had comparable early results, and no technique was superior to the others.

Om mens en menselijkheid

Abstract
In May 1945, shortly after the Liberation of the Netherlands, Dutch Reformed minister Willem Banning (1888-1971) published a sketch of a ‘personalistic socialism’. Shortly thereafter, he became one of the founding fathers of the renewed Dutch Labor Party. At the first convention of the new party he proposed that the process of renewal of socialism had to be informed by ‘spiritual values’. In Dutch historiography, the role of Banning as one of the founders of the Dutch Labor Party was never really been understood as religiously or even ideologically motivated. The so-called ‘Breakthrough-movement’ – which sought a new synthesis between political action and religious or ideological inspiration – has been generally interpreted in terms of opportunism: in order to persuade Catholic and Protestant workers to vote for the Labor Party, some spiritually and morally loaded vocabulary was added and the harsh anti-religious affiliation of classic socialist politics was (temporarily) toned down. In this article, I propose a new analysis of the breakthrough-movement, inspired by new studies on public debate in the Netherlands and in Europe between 1918 and 1960 and by an in-depth analysis of the intellectual development of Banning. This leads to the conclusion that the spiritual and religious sources of inspiration of the breakthrough movement should be seen as a turning point in the Dutch debate on the essence of humankind and his/her role in society, church and politics in a period still problematically labelled by the metaphor of ‘pillarization’.
Necessity of Bony Fusion After Surgical Treatment of Metastatic Spine Tumors
Authors: Alamanda Vignesh K. , Robinson Myra M. , Thompson Jeremy C. , Kneisl Jeffrey S. , Patt Joshua C. 
Published: January 2020

Introduction:
The role of bony fusion in influencing patient outcome and surgical revision rates in the treatment of metastatic spine disease is poorly defined. The goals of this study were, therefore, to evaluate the effect of fusion on revision surgery as well as on overall survival (OS) and functional status in patients with metastatic disease of the spine.

Methods:
A retrospective cohort study of a prospective database at a major cancer center was conducted. A total of 25 patients who met the inclusion criteria from January 2010 to December 2015 were included. Functional status, patient and tumor characteristics, fusion status, and survival were analyzed, and regression analyses were done. Bony fusion was classified as either present (seen across a minimum of three levels and crossing the tumor site) or absent as evidenced through CT images at minimum of 1-year postoperatively.

Results:
Twenty-five subjects with 28 surgical sites met the eligibility criteria to be included in this study cohort. Five surgical sites were found to have evidence of fusion on CT scans at 1 year after surgery, and 23 sites had no evidence of bridging fusion. No differences were found between the two groups in terms of OS, and ambulatory status (P > 0.10). Multivariate analysis did not reveal any specific factors affecting fusion. Mean follow-up was 23.7 months.

Discussion:
The lack of bony fusion is not an independent predictor of the need for revision surgery. The lack of bony fusion in patients with metastatic disease of the spine does not appear to negatively affect their OS or their ambulatory status. A discussion of factors affecting fusion is complex, and there are other factors that may also play a role. Large multicenter trials are needed to corroborate the preliminary findings seen in this complex patient cohort.
