Taxonomic Status of Neoechinorhynchus Agilis (Acanthocephala, Neoechinorhynchidae), with a Description of two New Species of the Genus from the Atlantic and Pacific Mullets (Teleostei, Mugilidae)
Authors: Tkach Ie. V. , Sarabeev V. L. , Shvetsova L. S.
Published: August 2014

The wide variability in morphological features, geographical and host ranges of mullet acanthocephalan parasite Neoechinorhynchus agilis (Rudolphi, 1819), raises the question of taxonomic status of this species. Rudolphi’s type and Yamaguti`s voucher specimens, as well as our own material from the WW Pacific and NE Atlantic region were used herein to provide comparative morphological analysis. Th e study revealed three different species of Neoechinorhynchus, N. (N.) agilis and N. (H.) personatus Tkach, Sarabeev et Shvetsova, sp. n. in the Atlantic and N. (H.) yamagutii Tkach, Sarabeev et Shvetsova, sp. n. in the Pacific. Strong morphological and morphometric differences were found between three described herein species from different hosts and regions. Th e dividing of N. agilis into three species, two of them are new, provides a basis for the further revision of host-geographical records of mullet acanthocephalan parasites.

Excessive Progression in Weekly Running Distance and Risk of Running-Related Injuries: An Association Which Varies According to Type of Injury
Authors: Nielsen Rasmus Østergaard , Parner Erik Thorlund , Nohr Ellen Aagaard , Sørensen Henrik , Lind Martin , Rasmussen Sten
Published: August 2014

Study Design

An explorative, 1-year prospective cohort study.

Objective

To examine whether an association between a sudden change in weekly running distance and running-related injury varies according to injury type.

Background

It is widely accepted that a sudden increase in running distance is strongly related to injury in runners. But the scientific knowledge supporting this assumption is limited.

Methods

A volunteer sample of 874 healthy novice runners who started a self-structured running regimen were provided a global-positioning-system watch. After each running session during the study period, participants were categorized into 1 of the following exposure groups, based on the progression of their weekly running distance: less than 10% or regression, 10% to 30%, or more than 30%. The primary outcome was running-related injury.

Results

A total of 202 runners sustained a running-related injury. Using Cox regression analysis, no statistically significant differences in injury rates were found across the 3 exposure groups. An increased rate of distance-related injuries (patellofemoral pain, iliotibial band syndrome, medial tibial stress syndrome, gluteus medius injury, greater trochanteric bursitis, injury to the tensor fascia latae, and patellar tendinopathy) existed in those who progressed their weekly running distance by more than 30% compared with those who progressed less than 10% (hazard ratio = 1.59; 95% confidence interval: 0.96, 2.66; P = .07).

Conclusion

Novice runners who progressed their running distance by more than 30% over a 2-week period seem to be more vulnerable to distance-related injuries than runners who increase their running distance by less than 10%. Owing to the exploratory nature of the present study, randomized controlled trials are needed to verify these results, and more experimental studies are needed to validate the assumptions. Still, novice runners may be well advised to progress their weekly distances by less than 30% per week over a 2-week period.

Injury-Reduction Effectiveness of Prescribing Running Shoes on the Basis of Foot Arch Height: Summary of Military Investigations
Authors: Knapik Joseph J. , Trone Daniel W. , Tchandja Juste , Jones Bruce H.
Published: August 2014

Study Design

Secondary analysis of 3 randomized controlled trials.

Objective

Analysis of studies that examined whether prescribing running shoes on the basis of foot arch height influenced injury risk during military basic training.

Background

Prior to 2007, running magazines and running-shoe companies suggested that imprints of the bottom of the feet (plantar shape) could be used as an indication of foot arch height and that this could be used to select individually appropriate types of running shoes.

Methods

Similar studies were conducted in US Army (2168 men, 951 women), Air Force (1955 men, 718 women), and Marine Corps (840 men, 571 women) basic training. After foot examinations, recruits were randomized to either an experimental or a control group. Recruits in the experimental group selected or were assigned motion-control, stability, or cushioned shoes to match their plantar shape, which represented a low, medium, or high foot arch, respectively. The control group received a stability shoe regardless of plantar shape. Injuries during basic training were assessed from outpatient medical records.

Results

Meta-analyses that pooled results of the 3 investigations showed little difference between the experimental and control groups in the injury rate (injuries per 1000 person-days) for either men (summary rate ratio = 0.97; 95% confidence interval [CI]: 0.88, 1.06) or women (summary rate ratio = 0.97; 95% CI: 0.85, 1.08). When injury rates for specific types of running shoes were compared, there were no differences.

Conclusion

Selecting running shoes based on arch height had little influence on injury risk in military basic training.

Ability of Sagittal Kinematic Variables to Estimate Ground Reaction Forces and Joint Kinetics in Running
Authors: Wille Christa M. , Lenhart Rachel L. , Wang Sijian , Thelen Darryl G. , Heiderscheit Bryan C.
Published: August 2014

Study Design

Controlled laboratory study, cross-sectional design.

Objective

To determine if sagittal kinematic variables can be used to estimate select running kinetics.

Background

Excessive loading during running has been implicated in a variety of injuries, yet this information is typically not assessed during a standard clinical examination. Developing a clinically feasible strategy to estimate ground reaction forces and joint kinetics may improve the ability to identify those at an increased risk of injury.

Methods

Three-dimensional kinematics and ground reaction forces of 45 participants were recorded during treadmill running at self-selected speed. Kinematic variables used to estimate specific kinetic metrics included vertical excursion of the center of mass, foot inclination angle at initial contact, horizontal distance between the center of mass and heel at initial contact, knee flexion angle at initial contact, and peak knee flexion angle during stance. Linear mixed-effects models were fitted to explore the association between the kinetic and kinematic measures, including step rate and sex, with final models created using backward variable selection.

Results

Models were developed to estimate peak knee extensor moment (R2 = 0.43), energy absorbed at the knee during loading response (R2 = 0.58), peak patellofemoral joint reaction force (R2 = 0.55), peak vertical ground reaction force (R2 = 0.48), braking impulse (R2 = 0.50), and average vertical loading rate (R2 = 0.04).

Conclusion

Our findings suggest that insights into important running kinetics can be obtained from a subset of sagittal plane kinematics common to a clinical running analysis. Of note, the limb posture at initial contact influenced subsequent loading patterns in stance. J Orthop Sports Phys Ther 2014;44(10):825–830. Epub 25 August 2014. doi:10.2519/jospt.2014.5367
Role of model initialization for projections of 21st-century Greenland ice sheet mass loss
Authors: Ađalgeirsdóttir G. , Aschwanden A. , Khroulev C. , Boberg F. , Mottram R. , Lucas-Picher P. , Christensen J.H.
Published: August 2014

Model simulations of the Greenland ice sheet contribution to 21st-century sea-level rise are performed with a state-of-the-art ice-sheet model (Parallel Ice Sheet Model (PISM)). The climate-forcing fields are obtained from the European Union’s Seventh Framework Programme project ice2sea, in which three regional climate models are used to dynamically downscale two scenarios (A1B and E1) from two general circulation models (ECHAM5 and HadCM3). To assess the sensitivity of the projections to the model initial state, four initialization methods are applied. In these experiments, the simulated contribution to sea-level rise by 2100 ranges from an equivalent of 0.2 to 6.8 cm. The largest uncertainties arise from different formulations of the regional climate models (0.8–3.9 cm) and applied scenarios (0.65–1.9 cm), but an important source of uncertainty is the initialization method (0.1–0.8 cm). These model simulations do not account for the recently observed acceleration of ice streams and consequent thinning rates, the changing ice discharge that may result from the spatial and temporal variability of ocean forcing, or the feedback occurring between ice-sheet elevation changes and climate forcing. Thus the results should be considered the lower limit of Greenland ice sheet contributions to sea-level rise, until such processes have been integrated into large-scale ice-sheet models.
Tidal pacing, skipped slips and the slowdown of Whillans Ice Stream, Antarctica
Authors: Winberry J. Paul , Anandakrishnan Sridhar , Alley Richard B. , Wiens Douglas A. , Pratt Martin J.
Published: August 2014

We summarize new observations of the deceleration and stick–slip motion of Whillans Ice Stream (WIS), Antarctica. We refine the location of the large sticky spots that resist motion between slip events, the locations of which are controlled by the patterns of subglacial water flow. Our examination of the long-term velocity time series for the ice stream reveals that the decadal-scale deceleration is not occurring at a steady rate, but varies at the sub-decadal timescale. This unsteady deceleration modulates the temporal evolution of a broad (~50 km across) surface-elevation bulge forming at the junction between the relatively narrow upstream portion of the ice stream and broad ice plain that constitutes the downstream end of WIS. Comparison of observations from April 2003 and November 2010 reveals significant changes in the tidally modulated stick–slip cycle that regulates motion on the ice plain. We observe that the timing of slip events has become less regular in response to decreased flow speed in the upstream portions of the ice stream. The decreased regularity of slip events has reduced the release of stored elastic strain during slip events, increasing the rate of deceleration.

An experiment on the effect of different sources of Arbuscular mycorrhiza (AM) fungi on tomato seedlings (var. Roma VF) was conducted at the Bangladesh Agricultural Research Institute, Gazipur during rabi 2007-08 and 2008-09. Eight sources of AM fungi viz., AM-01 (Jessore), AM-02 (Rahmatpur), AM-03 (Joydebpur), AM-04 (Ullapara), AM-05 (Jamalpur), AM-06 (Hathazari), AM-07 (Ishurdi), and AM-08 (Rajshahi) were studied along with a control and mixed sources on tomato seedlings. Soil based AM inoculum at the rate of 2.0 kg/m2 was used. Biomass yield of tomato (Roma VF) increased from 14.8% to 53.6% in 2007-08 and 32.1% to 58.4% in 2008-09 over control by inoculation with different sources of AM. The highest biomass yield (301 mg/seedling) of tomato (Roma VF) was observed with AM-05 (Jamalpur source), which was higher to all AM sources except AM-07 (Ishurdi source). Nutrient uptake by tomato seedlings was improved by inoculation with AM fungi. The AM fungi from all the sources appeared to be effective in enhancing the growth and development of tomato seedlings.

Published: August 2014

The experiment was conducted at the Molecular Breeding Lab of Plant Breeding Division, Bangladesh Agricultural Research Institute (BARl) to assess the inter and intra species diversity within the barley genotypes. Ten barley genotypes were used for polymorphism study through SSR markers. Among them, six markers showed distinct polymorphism within the barley genotypes. It was observed that the genotypes BB-1 and BB-3 were more diverged (0.255) compared to other genotypes. On the other hand, the genotypes BB-2, P-33, P-19, and P-25 were very much similar in their genetic level (83.00%) followed by BB-2, BB-4, BHL-19, P-19, BHL-18, BB-5, P-19, P-25, and P-33 (78.70%). The two dimensional graphical view of Principal Coordinate Analysis (PCO) showed the spatial distribution of the 10 barley genotypes along the two principal axes. The genotypes viz., BB-1 and BB-3 were found far away from centroid of the cluster and rest of the genotypes were placed around the centroid (Fig. 8). The genotypes that placed far away from the centriod were more genetically diverged compared to the genotypes placed near the centriod which were likely to be genetically more similar.

An economic survey of cowpea (Vigna unguiculata) storage practices in Kwara State, Nigeria
Authors: Fakayode B Segun , Omotesho A Olubunmi , Adebayo T Zainab
Published: August 2014

Grain cereals are the food security staples of the poor masses around the globe. However, a significant proportion of these crops, especially cowpea are lost during storage. This is more so the case in Africa where postharvest losses due to the absence of efficient storage for cowpea is alarming: between 30-70 percent. This study, therefore, examined the adoption of improved cowpea storage practices/facilities by cowpea farmers and traders in Nigeria, using Kwara State as case study. The study specifically investigated factors affecting cowpea storage practices. For the study, 180 households involved in cowpea storage activities were selected across the study area and interviewed. Data analysis tools were the descriptive statistics and logistic regression tools. The descriptive statistics was employed to analyse the socio-economics and cowpea storage practices of respondents, while the logistic regression tool was used to identify factors affecting respondents likelihood to adopt popular improved cowpea storage technique crib in the study area. The study results indicate that most of the respondents have not had any form of formal education. The common storage agro-chemicals used by the respondents were actellic liquid, actellic dust, and phostoxin. Crop storage practices identified in the study area were the traditional ones, involving the use of old drums, jute bags, earthen pots, gourds and rhumbus. The improved/modern storage practices identified comprised the use of cribs and a handful patronage of public silos. Logistic regression results showed that the perception of respondents about storage pest as threats to their crops, their household size, and credit availability variables are significant at 5 percent level, implying that these variables determine respondents likelihood to adopt the crib storage technique for their cowpea. However, the type of education whether formal or informal acquired by the respondents variable is insignificant and therefore, does not determine respondents likelihood to adopt the crib storage technique for their crops. Factor identified as constraints to efficient storage practices were inadequate credit facilities, high costs of and poor access to improved storage facilities. The study, therefore, concludes that there is an urgent need for the provision of credit facilities to cowpea farmers and grain traders alike, subsidy on improved storage facilities and ease of access to the improved storage facilities DOI: http://dx.doi.org/10.3329/bjar.v39i1.20079 Bangladesh J.

Authors: Zakaria M , Hossain MM , Mian MA Khaleque , Hossain T
Published: August 2014

Five protocols of micro tuberization were used to induce large size microtuber in three recommended potato varieties, namely Cardinal, Diamant, and Heera under complete dark condition. Tuberization was the earliest (11.8 days) in the protocol P2 (MS + 5 mg/l BAP + 500 mg/l CCC + 8% sucrose), which was closely followed by that in P1 (12.7 days) (MS + 5 mg/l BAP + 50 mg/l coumarin + 8% sucrose). Maximum number of microtubers/flask (12.8) was obtained from the protocol P1 followed by that of P2 (11.6) that contained growth retardant; but higher average weight of microtuber was obtained in the protocols P5 (30 days old plantlet + MS media containing 40 meq K + 10 mg/l BA + 9% sucrose), P4 (MS + 10 mg/l BA + 8% sucrose), and P3 (MS + 5.0 mg/l BAP + 6% sucrose) which contained BA in absence of growth retardant. The average weight of microtuber was the highest (329.0 mg) in protocol P5, followed by that in P4 (280.7 mg), while it was the lowest in protocol P1. The variety Diamant produced maximum average weight of microtuber (246.3 mg), while Heera produced minimum (226.1 mg), which was statistically similar to Cardinal (228.7 mg). The highest percentage (52.2) of >300 mg size and lowest percentage (19.3) of <150 mg size microtuber was produced in P5 protocol in the variety Diamant. On overall consideration, all the varieties performed best with the protocol P5. DOI: http://dx.doi.org/10.3329/bjar.v39i1.20143 Bangladesh J. Agril. Res. 39(1): 59-66, March 2014

Authors: Hossain MA , Bachchu MAA , Ahmed KS , Haque MA
Published: August 2014

The effectiveness of 17 indigenous plant powders as grain protectant were assessed against Callosobruchus chinensis (L.). The results indicated that among all the tested plant materials, tobacco leaf powder (TLP) had promising effects on inhibiting oviposition and reducing adult emergence, seed infestation, and weight loss by C. chinensis. Tobacco leaf powder offered complete protection of chickpea seeds applied at 20.0 g/kg seeds. Its lower doses exhibited efficacy in dose dependant manner. The lowest number of eggs (24.60), egg bearing seeds (23.40), adult emergence (23.20), seed infestation (8.28%), and weight loss (0.50%) were obtained from the TLP treated at 10.0 g/kg seeds, while the highest of these parameters were in untreated control. In the ovicidal test, TLP showed 100% inhibition at 20.0 g/kg seeds over control. The lowest number of adults (37.20) were emerged when larvae bearing seeds were treated with TLP at 20.0 g/kg seeds along with 59.39% retardation over the control and had no adverse effect on seed germination up to 3 months.

Authors: Hoq MS , Matin MA , Hossain TMB , Hossain S
Published: August 2014

The study was conducted in two districts Comilla and Jessore to examine the marketing chain, marketing cost, and margin, problems and some probable solutions for cabbage and cauliflower marketing. A total of 92 respondents consisting of 20 vegetable growers and 72 vegetables traders were selected as sample for the present study. A multi-stage simple random sampling technique was used for selection of samples. Both primary and secondary data were used for the study. About 60% farmers used van to carry the vegetables to the market. Average cauliflower marketing cost of farmer was higher than cabbage which was Tk.36.59 per quintal due to its special transportation arrangement. On the basis of the intermediaries, seven marketing chain were identified as a dominant. The chain Farmer?Local Traders (Faria) ? Bepari? Aratdar (urban) ?Retailer (urban) ?Consumer was identified as most dominant. About 39.60% product runs through this chain. In cauliflower marketing local traders, Bepari, retailer (urban) and retailer (rural) incurred the highest marketing cost than cabbage which were averaged Tk.65.75, Tk.248.47, Tk.205.69, and Tk.78.21, respectively, due to its perishable nature. In the case of farmers, local traders (Faria) and Bepari transportation cost is the highest. Commission charge was highest in the case of retailer (urban) and spoilage and damage cost was the highest for retailer(rural).The marketing cost was the highest for Bepari which were estimated Tk.212.74 for cabbage, Tk.219.87 for cauliflower and the marketing margin was highest for retailer (urban) which were estimated Tk.108.52 for cabbage and Tk.130.09 for cauliflower. Inadequate storage facilities and dominance of intermediaries were the major marketing problems identified by the farmers. Unstable price, barrier to entry in the terminal market, delays on ferryghat and spoilage and damage were the major marketing problem faced by the different intermediaries. The study suggested improving the storage facilities and establishment of organization to solve marketing problem of the farmers. Easy access of vegetables carrying vehicle in the terminal market, arrangement of separate cargo ferry would reduce the spoilage and damage of vegetables in the traders level.

Published: August 2014

The experiment compared the relative tolerance of some advanced lines and a variety of lentil viz. BD3859, BD3905, BD3867, ILL5087, ILL5133 and BINAmasur1 (variety) to soil flooding. The growth rates of the genotypes considerably reduced when flooding imposed at vegetative stage. However, the genotypes responded differently to flooding onward during recovery period. Leaf and roots showed highly vulnerable to flooding. Flooding promoted extensive leaf senescence and desiccation. Flooding induced damaging of root system was highly striking, despite there existed remarkable recoveries in some genotypes. The adverse effect of flooding was less pronounced on stem than other plant components. However, shoot growth reduction was 76-86% relative to control. Relative growth rate (RGR) of most plant components showed negative rate during flooding, but it varied from negative to positive during recovery period. Considering total plant biomass, flooding tolerance (FT) indices indicated that BINAmasur1 and BD3859 had comparatively better degree of tolerance to excess water. In contrast, ILL5133 and ILL5087 were susceptible to flooding for having negative FT indices.DOI: http://dx.doi.org/10.3329/pa.v18i2.17460 Progress. Agric. 18(2): 17 - 24, 2007
Purification and Characterization of Urea Transporter by SDS-PAGE from the Paddy Grown in Urea Treated Soil
Authors: Haque MS , Hasan MK
Published: August 2014

G-50 chromatography of extract of paddy plant induced by urea revealed the major three peaks F-1, F-2 and F-3 against the absorbance at 280 nm with the number of fractions. Chromatogram was also obtained from the control of extract of paddy, however, urea-induced paddy extract showed the higher absorbance than the control showing the higher protein content. F-1 fraction for both groups having the higher molecules are considered to have the urea transporter and are applied to SDS-PAGE for purification and characterization. For identification of urea transporter, a mixture of marker proteins- ?-galactosidase, BSA, egg white albumin, pepsin, trypsin inhibitor and lysozyme were used. Depending on the mobility of the sample, urea-transporter had been identified as a large band having the MW of 50.6 kDa compared to the MW of BSA. For control, SDS-PAGE shows the same band for urea-transporter but the expression was lower than the urea-treated paddy. In SDS-PAGE gel, both bands were homogenous showing the homogeneity of urea-transporter. The results demonstrate that urea application in the soil induces the expression of urea transporter which will be a new finding for the clarification of mechanism of urea transport in plants.DOI: http://dx.doi.org/10.3329/pa.v18i2.17463 Progress.

Published: August 2014

To regenerate plantlets both directly and indirectly, different explants (cotyledon, hypocotyl, root tip and shoot tip) of sweet gourd (Cucurbita moschata) were cultured on medium supplemented with different concentrations and combinations of NAA (0.0, 0.2, 0.5 and 1.0 mg/L) and BAP (0.0, 0.5, 2.0 and 5.0 mg/L). Cotyledon explants performed best in callus induction. The combination of 5 mg/L BAP and 0.2 mg/L NAA produced the highest callus frequency in cotyledon (90.0%). The calli derived from cotyledon, hypocotyl and root tip were cultured in MS medium supplemented with different concentrations of kinetin, BAP and/or NAA for shoot induction. Regeneration via callus was achieved only from cotyledon calli at a frequency of 65.0% on 2 mg/L BAP and 0.2 mg/L NAA. Shoot tips cultured for direct regeneration, in the same media containing 1 mg/L BAP or 1 mg/L BAP + 0.2 mg/L NAA resulted in 100.0% shoot differentiation. The regenerated shoots rooted on MS medium with or without 0.1 mg/L NAA (100%).DOI: http://dx.doi.org/10.3329/pa.v18i2.18093 Progress. Agric. 18(2): 61 - 66, 2007

An experiment was conducted at the Hill Agricultural Research Station, Khagrachari from May to November 2004 to find out the effect of planting time (1st week of June, July, August and September) and plant spacing (60 × 30 cm, 60 × 40 cm and 60 × 50 cm) on the yield and yield components of okra in hill slope condition during rainy season. The highest yield (12.53 t/ha) was obtained by the planting in July which was at par with June (11.69 t/ha). In case of plant spacing, the highest yield (9.02 t/ha) was recorded from close spacing at 60 x 30 cm that was statistically different from other two spacing and the widest spacing of 60 x 50 cm produced the lowest yield (8.06 t/ha). The treatment combination July sowing with 60 x 30 cm plant spacing produced significantly highest yield (12.86 t/ha).DOI: http://dx.doi.org/10.3329/pa.v18i2.18161 Progress.

Published: August 2014

An experiment was conducted to observe the incidence of brinjal shoot and fruit borer, Leucinodes orbonalis Guen. and to estimate their damages in five different brinjal varieties (viz. Laffa, Dohazari, Uttara, Islampuri and Amjuri) in the Plant Pathology Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from January to March, 2007. Peak period of brinjal shoot and fruit borer infestation was observed in March in all the five varieties. Maximum number of population (5.0 per plant) was recorded in Amjuri variety in first week of March whereas minimum number of population (0.33 per plant) was observed in Dohazari variety in the third week of March. No infestation was found from 3rd week of January to 3rd week of February in all the five tested brinjal varieties. Brinjal shoot and fruit borer caused damages to shoots and fruits of brinjal plant and it was found that all the tested brinjal varieties are susceptible to the borer. In case of all tested varieties, mean number of damaged shoots and fruits per plant differed significantly at different sampling times. Among the five varieties Amjuri was heavily infested with the highest infestation of shoot and fruit. In this variety, mean number of damaged fruit per plant was 2.11, 1.67 and 1.87 at first, second and third week of March, respectively. In Islampuri variety, shoot infestation was found only in the 3rdweek of March.DOI: http://dx.doi.org/10.3329/pa.v18i2.18162 Progress. Agric. 18(2): 75 - 80, 2007

Cocks and pullets from each of 4 genotypes; Redbro (RbRb), Naked neck (NaNa), Redbro dwarf (Rbdw) and Naked neck dwarf (Nadw) were crossed reciprocally for egg production trial. Egg quality (egg weight, egg diameter, egg length, shell thickness, membrane thickness, membrane weight, shell weight, % of shell, yolk color score, albumen diameter, albumen height, yolk diameter and yolk weight) were compared among 4 genotypes. Daily feed intakes, almost related to respected body size were reduced in Rbdw and Nadw hens by 7.41 and 19.89% than in normal sized RbRb hens. The feed conversion and hen day egg production were highest in Rbdw, intermediate in RbRb and Nadw and lowest in NaNa. Naked neck (Na) and dwarf genotypes had favorable effect on egg fertility and hatchability. Parents in both Na and dw inheritance had favorable shell thickness, shell membrane weight (%), albumen height and diameter, yolk height and diameter, albumen weight and albumen weight (%) and yolk weight, while NaNa had highest yolk weight (%). Both egg weight and chick weight percent were highest in RbRb x Rbdw genotypes, followed by RbRb, RbRb x Nadw, RbRb x NaNa, Rbdw x RbRb, Rbdw, Rbdw x Nadw, Rbdw x NaNa, Nadw x RbRb, Nadw x Rbdw, Nadw, Nadw x NaNa, NaNa x RbRb, NaNa x Rbdw, NaNa x Nadw and NaNa respectively. Chick weight as percent of egg weight irrespective of genotype was simply the functions of egg weight.DOI: http://dx.doi.org/10.3329/pa.v18i2.18167 Progress. Agric. 18(2): 115 - 121, 2007

Authors: Mahmud S , Mladenov PV , Chakraborty SC , Faruk MAR
Published: August 2014

The relationship between the activity of neurosecretory cells and gonad development of Perna canaliculus was investigated. The variation in staining intensity of the neurosecretory cells in different ganglia was evaluated. Changes in staining intensity of neurosecretory cells (NSC) were correlated with gonad development. The variation in colour intensity (CI) resulted from differences in the amount of secretory materials within the NSCs. The neurosecretory cell types A and B showed a similar pattern of staining intensity, and showed correlation with gametogenesis and spawning. At the beginning of gonad development, these cells possessed very few granules and the number of granules in the cells increased with gonad maturation. The staining intensity decreased in A and B- cells just after spawning. Cell types C and D did not show any substantial changes in colour intensity with gonad changes.DOI: http://dx.doi.org/10.3329/pa.v18i2.18169 Progress. Agric. 18(2): 135 - 148, 2007

Authors: Nowsad AAKM , Hoque MS , Hossain MI , Shikha MH
Published: August 2014

Fish sausage was prepared from the unwashed minces of 5 low-cost marine fishes (LMF) viz., red jewfish (Johnius orgentatus), sea cat fish (Tachysurus thalassinus), jwelled shad (Ilisha filigera) horse mackeral (Megalaspis cordyla) and skipjack tuna (Sarda orientialis) of the Bay of Bengal. Six different blend compositions from 5 individual minces of LMF were prepared by blending 15 to 30% of the individuals minces. Sausage was prepared from such mince blends by improving the textural strength of the products through different cooking process, ingredients and spices. Textural quality was determined in terms of gel strength, cook loss, sensory softness/firmness (S/F) and chewiness/rubburiness (C/R). Proximate composition and gel forming ability of individual mince blend varied with compositional differences of individuals species. Among the six blends tested, blend C showed highest gel strength which constituted with higher proportion of mince from red jewfish, sea cat fish and horse mackerel. In mince blend C, composition of red jewfish, sea cat fish, horse mackerel, jeweled shad and skipjack tuna were 30%, 20%, 20%, 15% and 15%, respectively. Unwashed and washed individual minces and the mince blend C were incubated at different temperatures from 35° to 55°C and then cooked at 90° or 100°C. Among different heating regimes, unwashed mince blend C showed the highest gel strength at 50°C for 1 hr incubation. Further cooking of the incubated gel at 100°C optimally increased the gelling ability. Among the four cooking methods tested, (boiling, two-step heating, broiling and autoclaving) autoclave cooking at 115°C obtained best textured sausage with significantly increased breaking force, folding test score and chewiness/rubberiness values and decreased cook loss values. Sausages prepared at 115° and 120°C, however, showed almost identical textural quality. Texture and flavor of sausage was affected by washing of the mince but the sensory qualities were unaffected.DOI: http://dx.doi.org/10.3329/pa.v18i2.18192 Progress. Agric. 18(2): 157 - 166, 2007

Authors: Rahman MR , Rahman MS , Khan MGQ , Mostary S
Published: August 2014

An experiment on polyculture of mahseer with Indian major carps at same stocking density was carried out for a period of 10 months from February 1 to December 1, 2004 in six experimental ponds. There were three treatments with two replicates each. Treatment 1 was designed with catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus mrigala), treatment 2 with catla (Catla catla), rohu (Labeo rohita) and mahseer (Tor putitora) while treatment 3 with catla (Catla catla), rohu (Labeo rohita), mrigal (Cirrhinus mrigala) and mahseer (Tor putitora). Mahseer of the treatment 2 was introduced instead of mrigal of treatment 1 and 50% of mrigal was replaced with mahseer in treatment 3. The stocking density in all the treatments was 30 fish/decimal (7500 fish/ha). The feeds were supplied at the rate of 3-7% of the body weight of fish. The gross and net productions recorded were 5362.78 and 5188.64, 5431.42 and 5262.32, 5357.11 and 5528.74 kg/ha/yr in treatments 1, 2 and 3 respectively. Though there was no significant difference (p>0.05) among the three treatments using ANOVA but the production in treatment-3 was slightly higher than treatments 1 and treatment 2. However, there was no negative effect of mahseer on the growth and production of Indian major carps. So, it can be concluded that polyculture of mahseer with Indian major carps (catla, rohu and mrigal) can be done in ponds.DOI: http://dx.doi.org/10.3329/pa.v18i2.18194 Progress.

Computer Based Tools to Locate and Measure the Disease Infected Area of Rice Leaves
Authors: Billah MM , Bhuiyan MM , Ashraf MA
Published: August 2014

Computer based image processing system has been developed to automatically calculate the damaged area and also to identify the location of disease infected area of rice leaves. The developed image processing system separates the infected regions on leaf by pixel-wise processing. The color intensities associated with image pixels are used as inputs, which are taken by the software and produce the desired output. Experimental results show that the proposed system can produce accurate results in every case whereas conventional eye-estimation technique is not accurate. The amount of damaged area, as identified by proposed software system, can potentially be used in many decision making processes, like determination of the amount of pesticides need to be sprayed in a field. Moreover, an automated machine can be combined with this software to eliminate the requirement of human operators. Also this system may eliminate the requirement of costly Leaf Area Meter.DOI: http://dx.doi.org/10.3329/pa.v18i2.18210 Progress. Agric. 18(2): 209 - 213, 2007

Authors: Islam SMF , Khan MI , Islam MS
Published: August 2014

Present study examined the socio-economic impacts of cotton IPM program of Food and Agricultural Organization (FAO) on yield, farmers income, health, environment and human resources development in selected areas in the southwestern region of Bangladesh. Ninety nine respondents were randomly selected by using two- stage stratified sampling technique. Farmers were stratified as farmers Field School (FFS), Non Farmers Field School (Non-FFS) and Non-IPM groups. Data were collected through two surveys i) baseline survey and ii) impact assessment survey. It was found that cotton IPM program has significant impact on uses of fertilizers, pesticides, yield, environment, bio-diversity and farmers knowledge of management of bio-resources and environment. The FFS farmers reduced fertilizers by 58% and pesticides by 62% compared to baseline situation. The FFS farmers reduced variable cost of production by 30%. However, cotton yield was less compared to base year due to unfavorable rainfall in the cotton field in 2004. Higher level of employment opportunities was created in different categories of farmers FFS (40 %), Non-FFS (28%) and Non-IPM (8%) after the participation in the cotton IPM program. Environmental Impact Quotient (EIQ) shows an improvement of 46% on FFS farms as compared to only 2% improvements caused at Non IPM farms. The cumulative score on soil improvement, observed biodiversity and attitude towards environment had significantly improvement on FFS farms (160%). Use of sources of information had increased (29%) at FFS farms and declined at other categories. The major changes were found in the recognition of number of beneficial pests of FFS farms. The observation and record keeping skill of farmers for participatory field experiments were found to increase for the FFS farms after participation in IPM program.DOI: http://dx.doi.org/10.3329/pa.v18i2.18279 Progress.

Published: August 2014

The experiment was conducted during rabi season, 2003-2004 at the Field Laboratory of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh. Genotypic variability, heritability and genetic advance for yield and yield contributing characters were studied on 55 tomato genotypes. Data were recorded on number of primary branches per plant, days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight, number of seeds per fruit, dry matter content of fruits, pH level of fruit juice and yield per plant. Very little differences were observed between genotypic coefficient of variation and phenotypic coefficient of variation for all the characters except dry matter content and yield per plant indicating that they were less influenced to environmental factors for their phenotypic expression. High heritability estimates coupled with high genetic advance in percentage of mean were obtained for number of primary branches per plant, number of days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight and number of seeds per fruit indicating wide scope for improvement through selection of these traits.DOI: http://dx.doi.org/10.3329/pa.v19i1.16982 Progress.
