Effects of shade and nitrogen levels on quality Bangladhonia production

A field experiment was conducted to determine the optimum shade level and nitrogen fertilizer for quality Bangladhonia (Eryngium foetidum L.) production at the Bangahandhu Sheikh Mujibar Rahman Agricultural University (BSMRAU) Research Farm during December 2002 to May 2003. The treatments consisted of four shade levels (0, 25, 50, and 75% shades) and five nitrogen rates (0, 115, 138, 161, and 184 kg N/ha). Shades were artificially created by using nylon nets of different mesh sizes and colours. Fifty percent shade and application of 161 kg N/ha independently as well as in combination gave the maximum fresh yield of Bangladhonia. β-carotene and vitamin C contents in Bangladhonia leaves were maximum in full sun light (0% shade) followed by 25 and 50% shade. Application of 161 kg N/ha produced the highest amount of β-carotene and vitamin C followed by 184 kg N/ha. The lowest amount of leaf fibre (1.30%) was recorded from 75% shade closely followed by 50% shade (1.76%), whereas the maximum amount of leaf protein was found at 50% shade. Application of 184 kg N/ha gave the highest amount of leaf protein and less leaf fibre that was followed by 161 kg N/ha. The results revealed that Bangladhonia performed better in terms of fresh yield and quality under 25-50% shade condition. Key Words: Bangladhonia; shade; nitrogen; yield; quality.

An Unusual Orbitocranial through and through Penetrating Injury by in Situ Teta: Can we do Better for this type of Unfortunate Patient?

Through and through orbitocranial penetrating injury by in situ teta is extremely rare. We managed such a case in Dhaka Medical college hospital with many limitations. In spite of all possible supports that were available in our set up, patient did not survive. Presentation, investigations, surgical and other supportive management will be highlighted in this case report. Key Words: Orbitocranial injury; penetrating injury; teta.

Effects of planting material and earthing-up on yield and yield contributing attributes of Mukhi Kachu

An investigation was carried out at Agricultural Research Station, Pahartali, Chittagong during February to August 2002 to select suitable size of planting material and proper time of earthing-up to obtain higher yield of Mukhi Kachu. Three planting materials, primary corm (40g), half cut corm (20g), and secondary corm (10g) and four times of earthing-up, 1 month, 2 months, 3 months, and 4 months after planting were used. Different planting materials showed significant difference on weight of total corms/plot, weight of total cormels/plot and cormel yield. Different times of earthing-up showed significant effects on the parameters studied except no. of cormels/hill and weight of cormels/hill. The highest (3.71 t/ha) corm yield was obtained when primary corms were planted and earthing-up was done three months after planting. The combination of P1E ( primary corm x 3 months after planting) gave the highest (8.37 t/ha) cormel yield.

Morphology of esophagus of Black Bengal Goat

The morphology of esophagus of Black Bengal goat was studied 6 Black Bengal goats of over six months of age of both sex in the Department of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh using. The topography, shape, size, esophageal length including cervical and thoracic parts were measured. The esophagus was sampled at six sites - cranial cervical, middle cervical, caudal cervical, at the level of thoracic inlet, at the middle mediastinum and at the level of cardia. The esophagus was 45-50 cm long. The cervical part of esophagus was 13-15 cm long and the thoracic part was 32-30 cm long. The highest and lowest diameter was found 5.1 cm and 3.2 cm at the cardia and at the cranial cervical part of the esophagus respectively.

Effects Of Textile Industrial Waste Water And Uptake Of Nutrients On The Yield Of Rice

An experiment was conducted at Mouchack textile industrial area of Gazipur for two consecutive years (1999-2000) to study the effects of use of industrial waste water on the yield, nutrient content, and uptake of Boro rice. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The six treatments in this study were: T1: uncontaminated field + fresh water, T2: uncontaminated field + mixed water, T3: uncontaminated field + contaminated water for non-contaminated field, and T4: effluent contaminated field + fresh water, T5: effluent contaminated field + mixed water, T6: effluent contaminated field + contaminated water for contaminated field. Among the six treatments, uncontaminated field + fresh water (T1) showed the best positive effect on rice. The N, P. K, and S contents and uptake were higher in T1, but Zn, Mn, Fe, Cu, and Pb were higher in T6 treatment. The treatment T1, gave the highest grain yield (5.23 t/ha in 1999 and 5.40 t/ha in 2000), followed by mixed water (4.19 t/ha in 1999 and 4.24 t/ha in 2000) in both the growing seasons.

Assessment of irrigation water quality of Bogra District in Bangladesh

Some important physio-chemical parameters of surface and groundwater of Bogra District were evaluated for the criteria of irrigation water quality. Forty four water samples were collected in the peak dry season (December-April) from different areas of Bogra District. The study revealed that temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium carbonate (RSC), total hardness (Ht) and Kelly’s ratio of waters were found within the permissible limits for irrigation purposes. Any initiative for surface and groundwater development for planned irrigation practices is highly encouraged. Key Words: Irrigation water (surface and groundwater); quality; Bogra District.

Study on Rehydration Characteristics of Dried Lablab Bean (Lablab purpureus) Seeds

The present study was carried out to evaluate the rehydration characteristics of solar and mechanically dried lablab bean (Lablab purpureus (L.) sweet; hitherto Dolichos lablab) seeds. Bean seeds with and without coat were used to study the rehydration properties. The rehydration ratios were higher for both mechanically and solar dried bean seeds without seed coat than those with coat. Mechanically dried without coat bean seeds had rehydration ratio of 2.34 while with coat was 2.06. For mechanically dried samples, the co-efficient of reconstitution were 0.58 and 0.56 for bean seeds without and with coat, respectively, and were higher than those of solar dried samples having co-efficient of reconstitution of 0.54 and 0.52 for bean seeds without and with coat, respectively. For both mechanical and solar drying the rehydration rate constant was higher for bean seeds without coat than those with coat. Both rehydration ratio and rehydration rate indicated that mechanically and solar dried bean seeds samples without coat showed better reconstitution properties than those with coat. Both fresh and dried bean seeds without seed coat gave higher nutrient content than their counterpart with coat. Solar and mechanical dried seeds were good source of nutrients.

Reduction of COD and pH of Textile Industrial Effluents by Aquatic Macrophytes and Algae

Effluents samples collected from post discharge of equalization tanks of local compositetextile mills of Saver were treated with aquatic macrophytes, algae and their combination. Theywere found to be effective for the reduction of chemical oxygen demand (COD) and pH. Sixty nineper cent of COD was reduced with the combination treatment of Nostoc, Eichhornia crassipes andPistia stratiotes. With the combination treatment of Nostoc and E. crassipes reduced 65 per centCOD in glass containers. pH was reduced from 11.2 to 8.6. Between earthen and glass containers,glass container was found to be more effective.Key words: Industrial effluents; COD; pH; Aquatic macrophytes; AlgaeDOI: 10.3329/jbas.v34i1.5487Journal of Bangladesh Academy of Sciences, Vol.34, No.1, 9-14, 2010
