  The study was conducted to determine the effect of seed cleaning and washing on the incidence of bacterial leaf blight (BLB) of rice cv. BR11. Six different treatments were used. They were farmer`s seeds clean seeds, diseased seeds, farmer`s seeds washed with tap water, farmer`s seeds washed with 20% brine solution and clean seeds washed with tap water. Three seed health testing methods namely paper rolled towel, cassette slide holder and liquid assay method were used for detection of BLB infection in seed. Seed health both before sowing and freshly harvested seeds from six different treatments were determined. Seedling vigour of clean seeds and brine solution washed seed were also higher than farmer`s seed and diseased seed. Xanthomonas oryzae pv. oryzae was identified through physiological, biological, serological, hypersensitive reaction and pathogencity tests in seeds of all treatments. Incidence of BLB in field plots were recorded at tillering stage and flag leaf stage. Maximum and minimum BLB disease was recorded in diseased seeds and brine solution washed seeds respectively for both situation.

  Twenty nine different genotypes/advanced breeding lines and four cultivars/checks viz. BR11, BR22, BR25 and BRRI dhan 38 of rice were selected for the study to examine and screen out the advanced hybrid lines, which are resistant/tolerant to BLB and sheath rot. Three accessions (22, 68, 157) showed resistant reaction in T. aman season and six accession (22, 54, 58, 68, 139, 157) showed highly resistant (HR) reaction and four entries (37, 62, 75, 128) were resistant to BLB in Boro season. One accession (58) showed resistant in T. aman season and three (59, BR11, BRRI dhan 38) were found highly resistant and one accession (54) showed resistant reaction to sheath rot in Boro season. So, these lines/varieties may be used as breeding material and cultivated for rice production.

  The experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during the period from November 2000 to May 2001 to find the effect of sulphur and nitrogen on the yield and seed quality of maize (cv. Barnali). The study included three levels of Sulphur, viz., 0, 10 and 20 kg ha-1 and four levels of Nitrogen, viz., 0, 60, 100 and 120 kg ha-1. Gypsum and urea were used as the sources of Sulphur and Nitrogen, respectively. The highest grain yield and 1000-grain weight were obtained with 20 kg S ha-1. The maximum no of grains/cob, the highest shelling percentage, the highest 1000-gain weight, Maximum grain yield and maximum stover yield were produced by the application of 120 N ha-1. Grain yield increased with the increasing rates of both Sulphur and Nitrogen but their interaction effects were not significant for all the quantitative characters under study. Seed quality attributes like germination percentage, vigour index, seedling shoot and root length and shoot and root dry weights were not influenced by Sulphur application. Nitrogen application had significant effect on vigour index, seedling shoot and root dry weights. The interaction between Sulphur and Nitrogen levels showed significant effect on seedling shoot and root dry weights. Maximum vigour index and root dry weights/ seedling of maize were found with 120 kg but the highest shoot dry weight/seedling was obtained with 100 kg N ha-1. Maximum shoot and root dry weights/seedling was obtained by applying 120 kg N ha-1 in combination with 20 kg S ha-1.

  The effect of delayed icing on the quality of ice-stored Brackish water shrimp (Penaeus monodon) was investigated by determining organoleptic, biochemical and bacteriological aspects. The live shrimp samples stored in ice immediately after harvest were organoleptically acceptable for 10 days while delay in icing for 4, 8 and 12 hrs shortened the shelf life to 7, 6 and 5 days, respectively. The initial pH of the live shrimp muscles was 6.63 which increased to 7.28 after 10 days of ice storage while in samples delayed in icing for 4, 8 and 12 h pH increased to 7.85, 7.93 and 7.95, respectively at the end of 10 days of ice storage. TVB-N value was increased from 5.88 to 32.76 mg/100g after 10 days of ice storage. The peroxide values in all the samples were lower than 8 meq/kg of oil upto 5 days of ice storage and then increased gradually with the lapse of storage period. The myofibrillar Ca2+-ATPase activity in presence of 0.5M KCl showed the maximum remaining activity of 0.52 μmol pi/ in live samples stored in ice immediately after catch. The myofibrillar solubility of samples immediately after catch was 80%, which decreased around 50% during 10 days of storage. On the other hand, the solubility of the samples kept at room temperature for different periods prior to icing were around 70% which decreased considerably to about 40% during 10 days of storage. The aerobic plate count (APC) increased considerably in the samples kept at ambient temperature for longer period prior to icing. The composition of bacteria in samples was Coryneforms (8.33%), Bacillus (7.40%), Micrococcus (16.66%), Achromobacter (8.33%), Flavobacterium/Cytophaga (25%), Pseudomonus (25%) and Vibrio (8.33%). Shrimp samples iced at 4,8 and 12 hrs delay dominated mostly by Micrococcus with 60%, 57.14% and 46.66%, respectively. During subsequent storage for 7 days, Micrococcus and Achromobacter were dominant in all the samples. However, Enterobacteriaceae was found in samples delayed 8 and 12 hr prior to icing.

  Seven species of marine fish such as Queenfish (Chorinemus lysan), Jew fish (Otolithus argenteus), Silver belly (Leiognethus spp.), hard tail (Megalespis cordyla), lizard fish (Saurida tumbil), Bombay duck (Harpadon nehereus) and catfish (Tachyssurus thalassinnus) having limited use in fresh market were used in present study for evaluation of gel forming ability under a wide range of incubation temperature. The resulting suwari gels were subjected to the puncture test, expressible moisture test, teeth cutting test and folding test. The gel strength of Chorinemus lysan suwari-gel in one-step heating showed the maximum breaking force at 45°C (1196 ± 32g) after incubation for 120 minutes. In case of two-step heating, the product heated at 40°C for 120 min had the highest gel strength (1485 ± 79g). The gel strength of Otolithus argenteus in one-step heating showed the higher breaking force (BF) at 50°C (926 ± 34g) for 180 min, while in two steps heating, the highest gel-strength of 1451 ± 49g was obtained at 45°C after an incubation of 120 minute. In Megalespis cordyla both in one-step and two-step heating, maximum breaking force was obtained at incubation temperature of 45-50°C. The gel-strength of Leiognethus sp. in one step heating had highest breaking force at 50°C for 120 minutes (1010 ± 51g) and in two-step process the highest breaking force was obtained after pre-heating at 40°C for 180 min (1323 ± 58g). The results of gel strength Saurida tumbil suwari-gel both in one step and two-step heating showed poor ability irrespective of incubation temperature used. H. nehereus showed poor gel strength with maximum range of 207-213g at the temperature range of 40 -50°C both in one and two steps heating at various incubation temperatures. In T. thalassinus, the highest gel strength of 420 ± 87 g was obtained at 35°C in 180 minutes during one step heating while in two step heating, the resulting suwari-gel of T. thalassinus was the highest after pre-heating at 35°C for 120 min (313 ± 12 g).

  Twelve seed samples of rice were tested and all were found infected by Bipolaris oryzae the cause of brown spot disease. Highest (5.5%) and lowest (1.5%) incidence was found in sample of Bhabokhali and Mahozompur, respectively. Four plant extracts viz. biskatali (Polygonum hydropiper), onion (Allium cepa), garlic (Allium sativum) and neem (Azadirachta indica) were evaluated against Bipolaris oryzae. Among the plant extracts, neem and garlic were the most effective against Bipolaris oryzae at 1:1 dilution. All other plant extracts were also effective against Bipolaris oryzae at higher concentrations.

  Twelve seed samples of rice were tested and all were found infected by Bipolaris oryzae the cause of brown spot disease. Highest (5.5%) and lowest (1.5%) incidence was found in sample of Bhabokhali and Mahozompur, respectively. Four fungicides viz. Bavistin, Hinosan, Tilt 250 EC and Dithane M-45 were evaluated against Bipolaris oryzae. Dithane M-45 was the best with 100% reduction of the prevalence of the pathogen and inhibited the mycelial growth at 0.3% of the seed weight as seed treatments and 500 ppm as mycelial growth inhibition test followed by Tilt 250 EC, Hinosan and Bavistin. All test fungicides were effective against Bipolaris oryzae at higher concentration.
