A total of 23 clear bands were scored, of which 21 (91.30%) bands were proved to be polymorphic. The highest proportion of polymorphic loci and gene diversity values were 43.48% and 0.187, respectively in the line five of Binasarisha-5/Daulot. The lower proportion of polymorphic loci and gene diversity values were 8.70% and 0.034; 8.70% and 0.026 in the line seven of the cross and one parent, Daulot, respectively. The co-efficient of gene differentiation (G st ) and gene flow (N m ) values were 0.677 and 0.237, found respectively from the Popgene analysis. Result of cluster analysis indicated that the nine accessions were capable of being classified into two major groups - one consists of only one parent Daulot ( Brassica juncea ) while another consists of Binasarisha-5 ( Brassica napus ) and all introgressed lines of C 6 generation (treated with colchicine in C 1 generation) resulted from the cross B. napus and B. juncea . Introgressed line seven and Binasarisha-5 showed the lowest genetic distance of 0.077. Higher similarity was found between Binasarisha-5 and introgressed progenies. Introgressed line one and Daulot showed the highest genetic distance of 0.709, which can be used as germplasm for breeding program that aim to improve Brassica . It was concluded that RAPD markers can be used for the study of molecular characterization and diversity in Brassica .

Four agricultural universities namely, Bangladesh Agricultural University, Sher-e-Bangla Agricultural University, Sylhet Agricultural University and Bangabandhu Sheikh Mujibur Rahman Agricultural University were considered in this study conducted in 2015-16. A total of 50 students were selected at random and were interviewed with a pre tested questionnaire. As the medium of instruction of their respective programs, English is a supplementary course in the agricultural universities of Bangladesh which aims to prepare the students to encounter global communication challenges. After the completion of graduation and post-graduation, the students make themselves ready to serve in various local and multinational organizations and companies. In the workplace, English requires additional focuses along with students’ subjective expertise due to their prime medium of communication in English. In the case of recruitment, employers often suggest them to develop English language proficiency. So, teaching and learning English is worthy, of focus in regard of the agricultural universities. In this study, the researcher has focused on different steps of students’ academic affiliation with English which includes students’ academic proficiency in English during admission, needs analysis, syllabus design, purposes of the course as ESP, content quality, hours invested, and assessment. This qualitative research was conducted by observation method and questionnaire survey for data collection. The study revealed that a large number of students studied English course who could communicate efficiently with foreign teams visiting Bangladesh. However, many participants had no clear idea about social and business English. They have suggested the universities to focus on student’s English proficiency for professional success.

However, inclusive information on the effects of wastewater on crop production and soil health is necessary for such intervention. This study was designed to evaluate these effects by demonstrating the contribution of municipal wastewater (hereafter called wastewater) on yield and nutrient requirement of wheat ( Triticum aestivum L.) cv Shatabdi. Five irrigation treatments - I 1 , I 2 , I 3 , I 4 and I 5 were tested in a Randomized Complete Block Design (RCBD) with three replications during November-March of 2007-2008, 2008-2009, 2009-2010 at the experimental field of the Bangladesh Agricultural University,  Mymensingh. The treatments I 2 -I 5 consisted of blended wastewater and I 1 of fresh water (control). The ratio of wastewater to total irrigation water was 0.25, 0.50, 0.75 and 1.0 in I 2 , I 3 , I 4 and I 5 , respectively. Wheat was cultivated with three irrigations and recommended doses of fertilizer in three consecutive years. Wastewater contained nitrogen (N), phosphorus (P) and potassium (K) @ 17.5, 3.7 and 10.3 mg/L, respectively, and irrigation by raw wastewater (I 5 ) contributed 19.1, 15.1 and 21.7% of the recommended N, P and K, respectively. Biomass yield increased with increasing fraction of wastewater in irrigation. Grain yield increased for the wastewater fraction of 0.50 - 0.75 in irrigation but decreased when irrigation was applied by raw wastewater. Excess fertilizer (under I 5 ) boosted up growth of wheat, but did not contribute to the grain yield. Number of grains per spike; and grain, straw and biological yields significantly (p = 0.05) increased due to the contribution of wastewater. Wastewater significantly improved grain and biomass production, with the largest value obtained in I 4 (4.61 t/ha grain yield and 11.36 t/ha biomass yield).  Raw wastewater in combination with recommended fertilizer doses caused over-fertilization that contributed only in biomass production but not in grain production of wheat and irrigation by wastewater substantially reduced fertilizer requirement of wheat.

Fungicides and plant extracts were sprayed at the base of each plant and adjacent soil at 40, 50 and 60 days after transplanting (DAT). Poultry manure and bio-agent were applied to the soil before transplanting. The highest reduction of mycelium growth (74.44 %) and sclerotia production (77.13 %) were recorded in Bavistin 50 WP by poison food technique. Topgan 50 WP and Ridomil Gold also had similar effects. The lowest incidence (7.10 %) of foot rot was observed in Bavistin 50 WP at 120 DAT that was similar with Topgan 50 WP and Ridomil Gold. The lowest disease severity (stem lesion area)  was also found in each of Bavistin 50 WP (0.71 cm) and Topgan 50 WP which resulted in  higher yield (18.07 ton/ha). Application of bio-agent ( Trichoderma harzianum ) also showed promising effect against foot and root rot disease.

Five treatments were laid out in a randomized complete block design with four replications. The treatments were: (1) soil test based inorganic fertilizer (NPKS @ 138-7-80-3 kg ha -1 ), (2) cow dung (3 t ha -1 ), (3) poultry manure (2 t ha -1 ), (4) mustard oil cake (2 t ha -1 ) and (5) control. Organic fertilizers were applied on dry weight basis. Inorganic fertilizers were applied along with poultry manure (PM), cow dung (CD) and mustard oil cake (MOC) as IPNS. Soil test based STB fertilizer and PM in IPNS provided maximum grain yield of rice (6.11 t ha -1 ). Maximum plant height and tiller numbers were found in MOC treatment, while the numbers of filled grains were higher in STB fertilizer and PM treated plots. The application of different organic sources as IPNS significantly influenced the N, P, K and S uptake in rice. However, the highest N, P, K and S uptake were found in the PM treatment.

There were four treatments: I 1 =Irrigation up to FC at 5 days interval after plant establishment (PE), I 2 = Irrigation up to FC at 10 days interval after PE, I 3 = Irrigation up to FC at 15 days interval after PE and I 4 = Irrigation up to FC at 20 days interval after PE. A significant response of broccoli to different irrigation levels was observed. Among the different treatments, I 2 (irrigation at 10 days interval) was significantly better yielding (19.98 t/ha, 20.63 t/ha and 16.24 t/ha in 1 st , 2 nd and 3 rd year, respectively). The lowest yields were observed from the treatment I 4 each in all 3 years. The highest seasonal water (382.30 mm, 296.58 mm and 305.00 mm in 1 st , 2 nd and 3 rd year) were used in treatment I 1 and the lowest (204.60 mm, 185.66 mm and 179.77mm in the 1 st , 2 nd and 3 rd year) were used in treatment I 4, I 3 and I 3 , respectively. The results suggest that irrigation at 10 days interval (I 2 ) might be optimum irrigation schedule for broccoli production on the basis of gross return.
