M.; Khan, M. S. R.; Hossain, M. M.; Hasan, M. K. This study was designed to identify and determine in-vitro antibiotics sensitivity patterns of bacteria associated with respiratory illness of human. A total of 60 throat swab samples were aseptically collected from 3 age groups of 1-20 years (young), 21-40 years (adult) and 41-60 years (old). Isolated bacteria then subjected to determine their in-vitro antibiotic sensitivity patterns. From this study, it was observed that bacterial flora present in the throat swab of human with their percentage of distribution were Staphylococcus spp. (40.54%) of which Coagulase positive Staphylococcus (32.43%) and Coagulase negative Staphylococcus (8.11 %), Klebsiella spp. (24.325%), Pseudomonas spp. (18.92%), E. coli (8.11 %) and Bacillus spp. (8.11 %). Percentages of isolated bacteria in different age groups were 29.73% in young, 40.54% in adult and 29.73% in old. Among the isolates Coagulase positive Staphylococcus, Klebsiella and Pseudomonas were the predominant species. Percentages of Coagulase positive Staphylococcus spp. were high in age groups of 21-40 years (21.62%) whereas Klebsiella spp. were the predominant species of age groups of 1-20 years (10.81%) and 41-60 years (8.11%). Pseudomonas spp were the predominant species (8.11%) in age groups of 41-60 years. The isolated Coagulase positive Staphylococcus spp and Klebsiella spp were resistant 10 amoxicillin and ampicillin but sensitive to ciprofloxacin, enrofloxacin and norfloxacin. Isolated Pseudomonas spp. showed resistant properties against amoxicillin, ampicillin petloxacin, gentamycin and furazolidone but sensitive to ciprofloxacin and nortloxacin. 2011-07-01T00:00:00Z http://localhost:8080/handle/123456789/2224 GROWTH AND YIELD OF T. AMAN RICE AS AFFECTED BY VARIETY AND SEEDLING NUMBER Mahmud, J. A.; Shamsuzzaman, A. M. M.; Haue, M. M.; Islam, M. M. A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during July to December 20 I 0 to find out the effect of I, 2 or 3 seedling(s) per hill on growth, yield and yield components of a modern inbred (BRRI dhan49) and four hybrid (BRRI hybrid dhan2, Heera2, Tia and Aloron) transplant Aman rice varieties. The experiment was laid out in randomized complete block design with four replications. Results showed that rice cultivars differed significantly in some characters at different growth stages, such as, tillers number, total dry matter weight, unfilled grain, grain filling percentage and insignificantly in some characters at different growth stage, such as, chlorophyll content, yield etc due to different seedling densities per hill. Numerically the higher grain yield was attributed mainly to the number of effective tillers per hill, filled grains per panicle and 1000-grain weight. Remarkable grain and straw yield were found from the interaction of.BRRI dhan49 planted I seedling and 3 seedlings per hill respectively. Among the hybrid rice varieties, the maximum grain yield was observed from the combination of BRRl hybrid dhan2 with I seedling per hill (V2Sd. 2011-07-01T00:00:00Z http://localhost:8080/handle/123456789/2223 EFFECT OF SPACING ON GROWTH AND YIELD OF DIFFERENT VARIETIES OF KNOL-KHOL Rahman, M. R.; Hossain, M. I. The experiment was conducted at Honiculture Farm, Sher-e-Bangia Agricultural University, Dhaka, during October 20 I0 to January 2011. The experiment was consisted of two factors, viz. lour varieties of Knol-khol (White Vienna, Big Ball, UFO and Early 005) and three spacing (30 em x 15 em, 30 ern x 20 ern, 30 em x 25 em). Result revealed that different varieties significantly influenced on growth parameter and yield of knollkhol. The maximum gross yield (74.93 t/ha) was recorded from the variety White Vienna. The maximum marketable yield (55.38 tlha) of Knol-khol was also obtained from the variety White Vienna. Different spacing also influenced significantly on most of the parameters under study. The spacing 30 em x 20 em showed better performances and the highest gross yield (66.28 tlha) as well as the highest marketable yield (48.32 tlha) were obtained from this spacing. Interaction effect of different varieties and spacing had a signiticant variation on yield contributing characters and yield of Knol-khol. White Vienna and spacing 30 cm x 20 cm gave the maximum gross yield (80.26 t/ha) and also the maximum marketable yield (59.90 t/ha). So the treatment combination White Vienna with 30 em x 20 em spacing is suitable for the maximum yield of Knol-khol. 2011-07-01T00:00:00Z http://localhost:8080/handle/123456789/2222 ECO-FRIENDL Y MANAGEMENT OF SHOOT AND FRUIT BORER (Earias vittella FAB.) USING BOTANICALS AND BIO-CONTROL AGENT Afroz, R.; Rahman, M. M.; Ali, M. R. A study was conducted at the Sher-e-Bangla Agricultural University, Bangladesh during May 2011 10 August 20 II to evaluate the effectiveness of botanicals and parasitoid for the management of okra shoot and fruit borer (Earias vittella Fab.). The experiment was laid out in a Randomized Complete Block Design (RCBD) comprising eight treatments viz., TI ; Neem oil @ 4mlll of water sprayed at 7 days interval, T2; Neem seed kernel extract @50 g/l of water sprayed at 7 days interval, TJ; Neem leaf extract @ 200gll of water at 7 days interval, T. ; Trichogramma evanescens @ 0.5g1plot at 7 days interval, T, ; Trichogramma evanescens @ 0.25g1plot at + neem oil @ 4mlll of water sprayed at 7 days interval, T6 ; Trichogramma evanescens @ 0.25g1plot + neem seed kernel extract @ 50gll sprayed at 7 days interval, T7; Trichogramma evanescells @ 0.25g1plot + neem leaf extract @ 200gll of water at 7 days interval, Ts ; Untreated control. Among the treatments T, (Spraying of neem oil @ 4mlll of water + release of Trichogramma evanescens egg parasitoid @ 0.25g1plot at 7 days interval) performed the best in terms of percent reduction of shoot infestation (96.50), flower bud infestation (83.33%) and fruit infestation by weight (86.90%). 2011-07-01T00:00:00Z
