It invites scientific write-up from the personnel involved in research and extension both at national and international level. In Bangladesh about 75% of the land is covered by rice, and rice is cultivated in different cropping patterns in a yearly sequence with temporal and spatial arrangement of other crops. Detailed information on country-wide cropping systems is a prime need for prioritization research and development activities to enhance agricultural growth of Bangladesh. To generate information of this vital issue the researchers of Rice Farming Systems Division of BRRI conducted a country-wide survey and verified the collected data through stakeholders consultation workshop arranged in 64 districts of Bangladesh. Huge information was generated on crops and cropping patterns at each and every upazila (Administrative unit) as well as on its national level. A special issue of Bangladesh Rice Journal has been dedicated to compile this information with a thematic area ‘cropping patterns of Bangladesh’. As usually all the manuscripts were peer reviewed and overviewed. This issue includes 15 articles. However, all the articles are interlinked. The first one presents overall scenario about crops and cropping systems in Bangladesh focussing on district-wise data. Each of the rest 14 articles describes the cropping systems of an individual agricultural region of the country with upazila- wise elaborate information. It is expected that this special issue of Bangladesh Rice Journal will be an excellent source of references on crops and cropping patterns of Bangladesh and will meet up the deep- felt requirements of farmers, extension personnel, researchers and policy makers as well. One of the objectives of Sustainable Development Goal is to double the productivity of agricultural sector by 2030. We hope to achieve the target this piece of work would serve as a milestone in the history of agricultural research in Bangladesh.

An in-depth study was conducted on the existing CPs of Bangladesh in each and every upazila (sub-districts) using semi structured questionnaire and data validation by the stakeholder consultation workshop conducted in each of 64 districts. Three hundred and sixteen CPs were identified throughout Bangladesh excluding the very minor ones. Topmost five CPs were only rice containing CPs, which covered 51% of the net cropped area. The most dominant CP was Boro- Fallow-T. Aman covering 27% of net cropped area. Results on major cropwise CPs, location-wise CPs, CP diversity and crop diversity etc are also presented herein.

The soils were analyzed for texture, pH, EC, N, P, K, S, and Na to determine the qualitative analysis of some essential plant nutrients in agricultural soil to examine the nutrient status of soils for assessing crop suitability. The texture classes were silt loam in Gournadi Upazila. Sand fractions varied from 13.25-26.25%. Silt fractions varied from 44.5-77.5% and clay fractions varied from 10.25-29.25%. The soil pH of Gournadi ranged from 7.16-8.72. The soil of this zone is practically alkaline. Measurement of electrical conductivity helps to identify the level of salinity. The EC values ranged from 0.09-0.24 dS/m which indicated the soils were none saline. Total N content at Gournadi ranged from 0.028-0.74%. The average total N content observed at this Upazilla was 0.11%.

  • Women Health and Disease Pattern in the Rural Areas of Bangladesh: a Case Study on Haimchar Upazila Under Chandpur District
    J. Asiat. Soc. Bangladesh, Sci. 40(1): 27-37, June 2014 WOMEN HEALTH AND DISEASE PATTERN IN THE RURAL AREAS OF BANGLADESH: A CASE STUDY ON HAIMCHAR UPAZILA UNDER CHANDPUR DISTRICT ALAK PAUL, MD. MAHBUB MURSHED AND SAMIA AKTHER Department of Geography and Environmental Studies University of Chittagong, Chittagong-4331, Bangladesh Abstract The present research has undertaken to understand the women health scenario in a remote rural char land of the country and their health awareness with hygienic practices. Most of the women in the study area were found illiterate and not fully conscious about health and health care aspects. The overall health condition of women in the study area was found very poor and affected various diseases from lack of personal attention and adequate health care. It is evident that most of the women age ranging from 26 to 45 in the study area were the most sufferer of different number of diseases like fever, diarrhoea, skin diseases, asthma, reproductive tract infections (RTI) and various gynecological diseases. It was also identified that, water and sanitation related diseases are very common among the women of the study area which may be the result of using unsafe water and unhygienic sanitation practices. Key words: Women health, Disease pattern, Health Care, FGD Introduction Health is a basic requirement to improve the quality of life. The international declaration of Health rights proclaims that “the enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being” (Perry 2000). Women’s health involves their emotional, social, spiritual, and physical well-being and is determined by the social, political, and economic context of their lives, as well as biology (Navarro and Shi 2001).

Physical feature and socio-historical background Kushtia is not an ancient township but one of the eighteen oldest districts in independent Bangladesh. There is no much evidence to know the ancient history of Kushtia. The only tool to be informed about the district what was portrayed through description by different persons based on different regimes in the region governed. Hamilton's Gazetteer has mentioned of Kushtia town and of the fact that the local people called the town Kushtay (Kushte). In Tolemy's map, several little islands have been portrayed under the Ganges basin. These islands are considered as ancient Kushtia. 1 The district was under Natore Zemindar in 1725. Then it was under Rajshahi civil administration of Kanadarnagar Pargana. 2 Later East India Company transferred Kushtia under Jessore district in 1776. It was brought under Pabna district in 1828. Then Mahkuma Administration was established under Kushtia in 1861 and then brought under Nadia district.3 During the British rule, railway connection with Kolkata, capital of British India, established in 1860, made the town an alluring location for mills and factories, including the Jagneshwar Engineering Works (1896), Renwick and Company ( 1904 ), and the Mohini Mills (1919).

  • Arsenic Contamination in Surface and Groundwater in Major Parts of Manikganj District, Bangladesh
    J. Bangladesh Agril. Univ. 13(1): 47–54, 2015 ISSN 1810-3030 Arsenic contamination in surface and groundwater in major parts of Manikganj district, Bangladesh Atia Akter, M. Y. Mia and H. M. Zakir1* Department of Environmental Science and Resource Management, Mawlana Bhashani Science and Technology University, Tangail-1902, Bangladesh and 1Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh, *E-mail: [email protected] Abstract The contamination of groundwater by arsenic (As) in Bangladesh is the largest poisoning of population in history, with millions of people exposed. Thirty (30) water samples were collected from 5 different Upazilas of Manikganj district in Bangladesh to determine the concentration of As as well as to assess the level of contamination. Concentrations of As in waters were within the range of 0.27 to 1.96; 0.43 to 5.09; trace to 6.69 mg L-1 at Singair, Harirampur and Ghior Upazila, respectively. But the concentration of As in waters both of Manikganj sadar and Shivalaya Upazila were trace. All surface and groundwater samples of Singair and Harirampur, and 4 groundwater samples of Ghior Upazila’s exceeded Bangladesh standard value for As concentration (0.05 mgL-1). The highest As concentration (6.69 mgL-1) was found in groundwater of Baliakhora village of Ghior upazila in Manikganj district. The cation chemistry indicated that among 30 water samples, 15 showed dominance sequence as Mg2+ > Ca2+ > Na+ > K+ and 14 samples as Ca2+ > Mg2+ > Na+ > K+. On the other hand, the dominant anion in water samples was Cl- followed by - 2- 2- HCO3 and SO4 .
