Electrical resistivity tomography (ERT) has turned out to be one of the most applied and user-friendly geophysical methods in geotechnical geoenvironmental research. ERT is an emerging technology that becoming popular nowadays for investigating subsurface conditions. Multiple attributes using various electrode configurations significantly reduce measurement time are suitable applications even hardly accessible mountain areas. It a noninvasive test characterization very sensitive method used...

The application of Trichoderma is a form biological control that has been effective in combating Xanthomonas oryzae pv. oryzae, the causative agent devastating disease known as bacterial blight rice. In this present study, four strains Trichoderma, viz., T. paraviridescens (BDISOF67), erinaceum (BDISOF91), asperellum (BDISOF08), and (BDISOF09), were collected from rice rhizosphere used to test their potentiality reducing blight. expression patterns several core defense-related enzymes genes...

Late blight of potato caused by an oomycete, Phytophthora infestans (Mont.) De Bary limits the production worldwide. management has been based on chemical fungicide application, and repeated use these fungicides introduces new more aggressive genotypes, which can rapidly overcome host resistance. Therefore, innovative effective control measures are needed if is to be reduced or eliminated. Some potential formulated bacterial bioagents viz. Pseudomonas putida (BDISO64RanP) Bacillus subtilis...

The resistance of ashgourd to the melon-cottonaphid, Aphis gossypii (Glover), and incidence aphid-transmitted viral diseases was investigated following recording aphid numbers trichome (plant hair) per cm2 leaf on four parts cucurbit, ashgourd, representing genotypes (Local Sylhet, Local Round, High Female CQ-10-90). Sylhet genotype found have highest density compared with those Female, CQ-10-90 genotypes, least infested by gossypii. percentage virus-infected plants also be lowest genotype....

Bacterial blight (BB) caused by X. oryzae pv. is one of the devastating diseases rice mostly in Asia. Genomes highly variable due to rearrangement large contents transposable elements and dynamic changes population regulated efficiency control measures used for BB management worldwide. In this study, genetic variation pathotypes Bangladesh was studied using aviruelnce gene based RFLP rep-PCR techniques aimed formulate pathogen targeted effective against rice. Eight field isolates were...

Bacterial panicle blight (BPB) has become one of the most destructive diseases rice worldwide and Burkholderia gladioli B. glumae are two major pathogens causing BPB (1). This disease causes several types damage, importantly grain spotting, rot, blight, which can result in yield losses 75% or more (1,3). In recent years, symptoms including sheath have been observed both inbred hybrid varieties. These resemble those cause cultivar-dependent losses. (3) also reported same for BPB. To confirm...

Objective: Until recently, management of repeat breeding in cattle remains a major problem to dairy farmers.This study was carried out improve the fertility cows, those did not conceive after three or more consecutive services.Materials and methods: Twenty-three cows were selected from Central Cattle Breeding Station Dairy Farm (CCBS & DF), Savar, Dhaka, Bangladesh.Data another 23 that conceived four services collected same farm as controls.The breeders synchronized for estrus with two...

Horizontal directional drilling (HDD) is a widely used trenchless method for underground utility connections. The associated ground settlement triggered by HDD depends on the size, types, and surface texture of pipe, diameter borehole, soil conditions. present study investigates due to construction 1067 mm HDD, which will replace an existing sewer siphon under SR-60 highway in Chino, California using empirical, numerical methods. Based results obtained from subsurface investigation,...

Genetic diversity was assessed for 66 local aromatic rice genotypes to identify parental having distant relationship through Mahalanobis’s D2 statistic. First six principal component axes above unity contributed 90.88% variation among the genotypes. Yield per plant showed highest contribution total divergence followed by grain breadth, days maturity and others. The under study were grouped into ten clusters. Clusters III VII comprised of maximum number (11) when Cluster X possessed single...

Experiments were conducted under laboratory condition to examine the efficacy of Chitosan and Yeast Elicitor suppress growth seed-borne fungi cucurbitaceous vegetables. Seeds bottle gourd, sweet snake wax gourd cucumber collected from seed traders Mymensingh districts different borne isolated, purified identified. Fourteen fungal species belonging twelve genera consisting Aspergillus flavus, niger, Botrytis cinerea, Fusarium moniliforme, oxysporum, Phoma exigua, Rhizopus stolonifer,...

An experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during Aman season to determine nitrogen requirement two aromatic rice varieties (Kalizira, and Chinisagar). There were five N levels, viz. N0 (0 kg ha-1), N20 (20 N40 (40 N60 (60 ha-1) N80 (80 ha-1). Application significantly increased harvest components, grain harvest, straw both varieties. Both Chinisagar variety higher than that Kalizira. no significant difference...

In Bangladesh, Fusarium proliferatum is a prevalent pathogen of maize plants that poses significant threat to human health and livestock by producing carcinogenic fumonisin. However, the use Bacillus species, which can colonize infected plant parts, has been practiced globally mitigate fumonisin contamination in maize. this study, B. subtilis MMM1, native isolate from rhizosphere, was found be most effective antagonist against F. proliferatum, reduced their mycelial growth total accumulation...

Citrus is one of the most important fruit crops Bangladesh in terms acreage, production and economic value to growers. However, citrus severely compromised by leafminer (CLM) affecting both nursery orchard. growers conventionally spray different chemicals control this insect which negatively impact their environment health. Therefore, alternative management options conventional practice was required. To provide effective integrated pest (IPM) option(s) manage CLM nursery, studies were...

An experiment was conducted to test the efficacy of a mechanical barrier around tree trunk with one spray Cypermethrin @ 1 ml/l and turmeric powder extract 15 g/500ml water applied in integrated approaches against mango mealybug on tree. There were 7 treatments including control. The Mechanical barrier, ml/l, Turmeric water, + spray, untreated Three-year-old plants grafted from 5-year-old (Variety Amropali) planted pots used experiment. treatment, gave highest reduction population 87.06%...
