Soil Flooding Tolerance in Lentil at Vegetative Stage
Authors: Nessa B , Islam MR , Haque MM , Ahmed JU 
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.

Authors: Akter J , Haque MS , Karim MA 
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 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.

Relationship Between Gonad Condition and Neurosecretory Cell Activity in the Green-Lipped Mussel, <i>Perna canaliculus</i>
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

Improved Methods for the Preparation of Fish Sausage from the Unwashed Mixed Minces of Low-Cost Marine Fish
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.
