Response of Potato to Ash as an Alternative Source of Potassic Fertilizer

An experiment was carried out during rabi season of 2011-2012 in the experimental field of Soil Science, Bangladesh Agricultural University (BAU), Mymensingh. The objectives of present research work was to evaluate ash as an alternative source of potassic fertilizer for potato cultivation. The treatment combinations were i) Control (No K), ii) 100% K of recommended dose from muriate of potash (MoP), iii) 75% K from MoP+ 25% K from ash, iv) 50% K from MoP + 50% K from ash, v) 25% K from MoP + 75% K from ash, and vi) 100% K from ash. The result of the experiment indicated that various combinations of ash and MoP influenced the yield, yield contributing characters (length of the tubers, breadth of the tubers, number of tubers per hill, weight of tubers per hill, weight of ten tubers and gross yield of tubers per plot), K content of po tato as well as weed infestation. Among the treatments the highest yield was obtained from 50% K from MoP + 50% from ash (T3) treated plot. The K content in the potato tuber and weed infestation was also highest for that plot. Considering the yield contributing parameters, yield and number of weeds the T3 (50% K from MoP + 50% K from ash) treatment was found more suitable than others

Young people transitioning from out-of-home care and relationships with family of origin: An examination of three recent Australian studies

It is generally accepted (for example, Stein and Wade) that those young people who are able to establish positive relationships with their family in care and/or when transitioning from care are more likely to have a positive self-identity and self-confidence, and overall better outcomes. Conversely, poor or non-existent family links may contribute to low self-esteem and limited confidence. Here we present the findings of three recent qualitative Australian studies on young people transitioning from care, which include an overview of their relationships with family of origin. We examine the strengths and weaknesses of these relationships, and suggest implications for practice reform

Effectively preparing young people to transition from out-of-home care: An examination of three recent Australian studies

International research consistently depicts young people leaving out-of-home care (care leavers) as being particularly disadvantaged and as having significantly reduced life chances (Munro et al., 2005; Stein, 2008). This is not to suggest a simplistic causal relationship between any experiences of state care and poor later outcomes-care leavers are a heterogeneous group, and have varied backgrounds and experiences. But pre-care experiences of abuse and neglect, combined with poor incare experiences, accelerated transitions to adulthood, and a lack of ongoing support after leaving care, make many of them vulnerable to a number of poor outcomes

Arsenic limits trace mineral nutrition (selenium, zinc, and nickel) in Bangladesh rice grain

A reconnaissance of 23 paddy fields, from three Bangladesh districts, encompassing a total of 230 soil and rice plant samples was conducted to identify the extent to which trace element characteristics in soils and irrigation waters are reflected by the harvested rice crop. Field sites were located on two soil physiographic units with distinctly different As soil baseline and groundwater concentrations. For arsenic (As), both straw and grain trends closely fitted patterns observed for the soils and water. Grain concentration characteristics for selenium (Se), zinc (Zn), and nickel (Ni), however, were markedly different. Regressions of shoot and grain As against grain Se, Zn, and Ni were highly significant (P <0.001), exhibiting a pronounced decline in grain trace-nutrient quality with increasing As content. To validate this further, a pot experiment cultivar screening trial, involving commonly cultivated high yielding variety (HYV) rice grown alongside two U.S. rice varieties characterized as being As tolerant and susceptible, was conducted on an As-amended uniform soil. Findings from the trial confirmed that As perturbed grain metal(loid) balances, resulting in severe yield reductions in addition to constraining the levels of Se, Zn, and Ni in the grain

A review of food security and the potentials to develop spatially informed food policies in Bangladesh

Background:Food security globally depends primarily on three components: food availability, food access, and food utilization. Regional variations of these components may affect food security via spatial differences in natural, social or economic conditions and the interaction of these in a complex environmental system.Purpose:It is important to understand the regional variation of food security, particularly where and under what natural and socio-economic circumstances people become vulnerable to low food security in a country.Methods:This article provides an overview of food security in Bangladesh in terms of the three main components, identifies knowledge gaps in present food security research, reviews possible impacts of climate change on food security, and sourced a wide range of spatio-temporal data relevant for food security.Results:The study highlights potentials and indicates different processes to develop spatially informed food policies in a country, particularly focuses on Bangladesh. This will contribute to improved food security by considering regional food security conditions, region-specific deficits, climate change, other future risks, and devises actions related to the respective components.Conclusion:The study concludes that different processes can provide a foundation for policy development and these will advance research-policy linkage to improved food security
