ABSTRACT:In the management of the adult dental patient efforts are geared towards the preservation of permanent dentition as it is important for maintaining normal occlusal relationship, play role in aesthesis, speech, influence food habit and nutrition. This hospital based descriptive type of cross sectional study was done at Exodontia Department of Dhaka Dental College and Hospital to identify the factors that contribute in tooth extraction among the respondents. The study was carried out during the month of January to June 2009 and 110 respondents selected purposively. The study showed the majority of the respondents (57.3%) were in the age group of 20-39 years. Their mean age was 36.85.years, SD of age was ±13.85 and age range was 15-85 years. Among the respondents 46.4% were male and 53.6% were female. Dental caries was the leading cause of tooth extractions in 68% cases. It was also observed that post filling complication contributed in 33% cases of extraction. Patient requests due to economic cause in 16% cases, negligence in 11% cases and even distance of the treatment centre from residence reported in 15% cases. The treatment philosophy of the centre played a vital role. Heavy rush of the patient and inconvenient conservative treatment schedule caused many unnecessary extractions.

Incidence pattern of rice caseworm were studied from T. Aman (July -December)

Crop production has contributed significantly to global carbon footprint (CF). Characterizing the carbon footprint of agricultural production offers key information for achieving low carbon agriculture. Bangladesh has struggled for long and worked hard for increasing food production capacity for its large growing population. It is necessary to choose the crops and management practices which have low CF to maintain a win-win situation between food production and greenhouse gas (GHG) emissions. However, the CF of Bangladesh’s crop production has not yet been assessed. Therefore, this study was conducted to estimate the CF of lentil as one of the major legumes cultivated in Bangladesh. The crop was cultivated at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU) Farm, Mymensingh i.e. Agro-ecological zone (AEZ 9) during November, 2013 to April, 2014 by following standard management practices. The Carbon footprint was calculated by using the collected emission factors from literature as default values for each input and operation used for the production of crops as per guideline of ISO (2006) and IPCC (2006). The GHG emissions in the crop fields are taken from the studies of Pathak and Aggarwal (2012). The yield of lentil was 0.90 t ha-1 with a CF of 406 kg CO2-equivalentst-1 of lentil. Direct and indirect GHG emissions singly contributed the half of CF accounting 52.54% of total CF. The contribution of fertilizer, irrigation, machinery and labor inputs to the overall carbon footprint were 23.16%, 15.97%, 1.26% and 7.06%, respectively. Among the fertilizers, nitrogenous fertilizer was dominant and singly contributed to 70% of fertilizer CF. However, for developing best management practices for climate change mitigation in crop production of Bangladesh, further studies of soil and regional specific CFs of lentil are needed.Progressive Agriculture 27 (2): 162-167, 2016

Ten genotypes of chickpeas viz. CM-1, CM-2, CM-72, CM-88, CM-1918, C-44, K-850, C-727, Thal White and 86135, were compared for their relative drought tolerance in terms of yield and yield components in field experiment. The genotype CM-2 proved superior to other varieties in almost all the characters studied. It produced maximum number of pods per plant (87.20), gave the highest yield per plant (18.97 g), and more elliptic index of leaf (71.81) under stress conditions. Based on these characters this genotype may be advanced further.
