A field trial was carried out at Farm Machinery Technology Dissemination (FMTD) project site, Sujanagor, Pabna to test performance of planting methods with Bangladesh Agricultural Research Institute (BARI) inclined plate planter, BARI Bed planter over conventional manual planting method for sowing lentil during 2014-15. Mechanical planting method with BARI Inclined Plate Planter showed highest yield (1.67 tha-1) whereas it was obtained1.54 tha-1 for bed planter and 1.41 tha-1 for conventional manual planting method. Planting methods exhibited non significant response on yield attributes like number of plants population, plant height, seed pod-1, dry weight of 10 plants and weight of 100 seeds. However, highest no. of pod plant-1 (168.83), primary branch (6.77) and secondary branch (33.67) was obtained from planting by IPP and these three parameters were shown lowest value (70.20, 3.5 and 11.8 respectively) in manual seeding methods. Total Cost of complete land preparation and planting was exhibited lowest for seed sowing with BARI Inclined Plate Planter (2016 Tk. ha-1) and it was 2727 Tk. ha-1 for BARI bed planter and highest for conventional manual seed sowing method (4433 Tk.ha-1).J.

An attempt was made to forecast the 17 monthly climatic variables for 2005-2012 of Dinajpur using the univariate Box-Jenkin’s ARIMA (autoregressive integrated moving average) modeling techniques for 1948-2004. The 8 years data for 1973-1980 were missing and those data were replaced with the 4 years monthly forecasted data for 1948-1972 and 1981-2004 (reversing the years). The well fitted ARIMA (autoregressive integrated moving average) models were selected from the possible 16 ARIMA models based on the minimum root mean square forecasting errors (RMSFE) with the last 24 observations for all the cases and the residuals followed stationarity and normality. Several outliers were detected in the data which were replaced by the forecasted value. The fitted model for sunshine data (1989-2004) was found ARIMA (1, 1, 1)(1, 1, 1)12 and for evaporation data (1987-2000) was ARIMA (1, 1, 2)(1, 1, 1)12. . The findings supports that the changing term of the climatic variables may have adverse impacts on the crop production in this country.J. Environ. Sci. & Natural Resources, 10(2): 163-170 2017

Dhaka is one of the densely populated megacities in developing countries with rapidly growing urban population. A significant portion of Dhaka’s population lives in informal settlements and is truly deprived of adequate water services. The study was intended to explore obstacles behind promoting sustainable water services to urban poor in Dhaka city as well as to find out opportunities in this regard. A questionnaire survey was conducted amongthe officials of 3 government organizations and 3 non-governmental organizations. In Dhaka city, water services provided by the Dhaka Water Supply and Sewerage Authority is largely groundwater dependent, and a small amount of supplied water comes from surface water sources. The study revealed that compare to rising water demands, supply is absolutely unsatisfactory to city dwellers mainly due to poor infrastructures, lack of sustainable planning and management practices, population pressure and financial constraints. The study showed that conjunctive use of surface water and rainwater, with limited extraction of ground water could be better way for providing sustainable water services to urban poor in Dhaka city. Moreover, effective coordination between government organizations & NGOs and incorporation of private sectors and local community in the service sectors can help to provide sustainable water services.J.

A total of 20 chickpea seed samples were collected from BARI, Gazipurand different locations of Savar, Dhaka district. Blotter method was used for detection of the associated fungi of chickpea seeds. Altogether 14 fungi comprising 12 genera namely Aspergillus flavus, Aspergillus niger, Aspergillus sp, Botryodiplodia theobromae, Botryti cinerea, Curvularia lunata, Chaetomium globosum, Cladosporium sp., Colletotrichum dematium, Fusarium oxysporum, Macrophomina phasaelina, Rhizoctonia solani, Rhizopus stolonifer and Stemphylium sarciniforme were isolated from chickpea seed samples. Among the fungi isolated fungi, F. oxysporumwas most prevalent with an average incidence of 18.95% and found in all the seed samples. The germination of seed samples varied from 55-90 % on blotter. The pathogenic fungi and other storage fungi like Aspergillus caused lower the germination of the seeds.A pathogenicity test was conducted with 20 isolates of F. oxysporum against their origin of chickpea seed samples in pot culture. The pathogenecity ranged from weak to highly pathogenic. The isolates FO 19, FO 17, FO 11 and FO 18 were highly virulent. The isolates FO 9, FO10 and FO 15 were virulent and rest of the isolates were moderately virulent. The isolates FO 2 and FO 3 were weak pathogen.J. Environ.

The present study was conducted to measure waste production and its categories of JKKNIU, and find out its management options. Samplings were done in Student Hall, Teachers’ and officers’ dormitory, and central cafeteria of the University. Waste categories were organic, biodegradable, recyclable, inert materials etc. Major portion of the waste was organic biodegradable, about 65% of total waste. Waste are not being collecting and disposing properly due to unavailability of facilities, and this creating environmental pollution. Landfill, composting, and anaerobic digestion etc. could be use for proper management and to produce bio-gas and bio-fertilizer. Integrated waste management option would be better solution.J.

Fire safety and security system in high-rise buildings has been a significant issue from the last century. However, there are numerous provisions for safety measures from such fires and the magnitude and nature of the problem of this hazard has been unknown. This study identifies the location of high-rise buildings in Tangail pourashava through an extensive survey and then identifies the unique fire safety problems of those buildings and their associated fire risk. As it turns out, most of those buildings are highly vulnerable to fire risk due to lack of major fire fighting equipments and defiance of related laws and regulations. The study then addresses the means to provide fire safety in those buildings from both design and codes perspectives. It elaborates on the need to provide both building and occupant based protection to achieve the best results. It concludes with an overview of the special problems associated with high-rise buildings combined with specific use and occupancy-related requirements, employee training and response. J. Environ. Sci. & Natural Resources, 10(1): 33-40 2017

The experiment was conducted to find out the morpho-physiological variability in response to different sowing dates in four lines of Quality Protein Maize (QPM) in in the Field Laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh. The study was carried out with four lines of maize and two sowing dates, 15 November (T 1 ) and 15 December, ((T 2 ). Sowing date differed significantly in plant height, length of leaf blade, length of leaf sheath, leaf breadth, cob length, cob diameter, length of tassel, days to 50% tasselling, days to 50 % silking, days to maturity, number of cobs per plant, cob weight, number of grain per cob. 1000-seed weight, percent underdeveloped cob, total dry matter and grain yield, but did not differ in number of leaves and protein percent. The lines differed significantly among themselves in those characters except number of leaves per plant, length of leaf sheath, cob length, cob diameter, days to 50% tasselling, number of cobs per plants and number of grain per cob. The line Across 8666 (V 2 ) and (V 3 ) gave the highest grain yield 4.57 and 4.55 and the lowest from (V 4 ) lines 4.41 tons per hectare. The 15 November sowing time (T 1 ) gave the highest grain yield 4.86 tons per hectare. In case of interaction, the earlier planting time (T 1 ) showed better performance with all lines. On the other hand, the highest yield was found from combination of line V 2 and V 3 with earlier planting time (T 1 ). J. Environ. Sci. & Natural Resources, 10(1): 117-124 2017
