This study conducted a case study on four selected areas (Barakpur, Srirampur, Prbazar, and Gouranandapur) on the Kapotaksha river bank at Jhikargas Upazila. This river water pollution occurs by some natural process such as flood, storm, and natural biodegraded. But human activities are major reasons for the river water pollution. Industrialization, urbanization, domestic waste, sewage system, agrochemicals, etc are major causes for river water pollution. This more polluted water has an impact on human health and environment. This study was conducted to find out the polluted water due to various types of diseases such as scabies, asthma, dysentery and respiratory disease. Most of the people (49%) are affected by Scabies, 4% are affected by diarrhea, 5% are affected by dysentery, 25% of people are suffering from respiratory diseases and 4% are suffering from asthma and the polluted water pollutes soil by using the water in agriculture purpose answered by 20% respondents which is 100% of farmer respondents. If someone does not use this water can not affect soil answered by 80% of respondents. This river water becomes more polluted and harmful for human health and environment because this water hampered by the local colony, local trader, lack of proper management of sewage system, miss-use on the riverbank area for the dumping various solid waste on the river bank, chemical fertilizers, industries etc. At present now we cannot fulfill control this continuous river water pollution but we can minimize this problem and it would be positive for human health, others living organisms and Environment.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>1-9, 2020</em></strong></p> 2020-07-22T06:25:25+00:00 ##submission.copyrightStatement## Assessment of genetic divergence of deshi jute (Corchorus capsularis) germplasms by using phenotypic characters 2020-07-22T06:34:11+00:00 A Miah NR Saha MY Ali M Kamrujjaman MSMS Parvej <p>Twenty-two morpho-agronomic traits of 42 jute genotypes, including 4 varieties with 38 accessions of <em>C. capsularis</em> were evaluated to assess the extent and patterns of variability and their relationships. Seed traits exhibited a wider range of variation than fiber traits. Qualitative traits were also the most informative. Considerable ranges of variability were observed in stem colour, petiole colour, stipule colour, plant technical height, base diameter, dry fibre weight and dry stick weight. Based on major yield contributing characters’ accessions 628, 633, 635 and 646 performed better in most of the cases than the control variety&nbsp;&nbsp; CVL-1, CVE-3, BJC-7370 and BJC-83.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>10-18, 2020</em></strong></p> 2020-07-22T06:25:33+00:00 ##submission.copyrightStatement## Performance study on yield and yield attributes of seven white jute breeding lines at different regions of Bangladesh 2020-07-22T06:34:12+00:00 A Miah NR Saha MZA Rafiq MY Ali M Hasanuzzaman <p>The study was conducted to know the performance of growth, yield contributing parameters and yield of seven white Jute breeding line and two checks (CVL-1 and CVE-3) at five different jute research regional stations of Bangladesh Jute Research Institute (BJRI) during the period from March to September 2014. The experimental data was laid out in a completely randomized block design with three replications and the means were adjudged by DMRT at 5% level of probability. The performances of experimental lines were showed statistically significant variation among the studied whole growth, yield and yield attributing traits. Analysis of variance revealed significant differences among the treatments for fibre yield and stick yield at Rangpur plant height, base diameter, fibre and stick yield at Manikganj plant height and fibre weight at Chandina, Faridpur and plant height at Kishoreganj. It was revealed by the pooled mean performance that among the genotypes, the line C-5018 m produce the tallest plant among the lines. The Line C-5030 recorded both the highest plant population (0.241 m/ha) and base diameter (21.79 mm). The line C-5133 showed highest Green weight with leaves (43.12 t/ha) whereas C-5149 recorded the greatest Green weight without leaves (35.02 t/ha). The most important parameter is the fiber yield and the highest-fibre weight (2.83 t/ha) was recorded by the line C-5149 among the seven breeding line. The line C-5149 also recorded the highest amount of stick yield (6.01 t/ha). However, pooled mean over stations revealed that no progenies, C-5018, C-5030, C-5036, C-5044, C-5133, C-5136, C-5149 out-yielded both the check varieties CVL-1 (2.83 t/ha) and CVE-3 (2.54t/ha) whereas C-5149(2.83t/ha) shows the equivalent result as CVL-1. It was also revealed that C-5030(2.61t/ha), C-5136(2.70t/ha) and C-5149(2.83t/ha) out yielded check variety CVE-3 (2.54t/ha).</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>19-25, 2020</em></strong></p> 2020-07-22T06:25:40+00:00 ##submission.copyrightStatement## Genetic divergence analysis of deshi jute (Corchorus capsularis) based on fibre yield and its attributing traits 2020-07-22T06:34:14+00:00 A Miah NR Saha MY Ali M Kamrujjaman MSMS Parvej S Farabi <p>Commercially important natural fibres considered as fiber of the future are obtained from the bark of two jute species (<em>Corchorus capsularis </em>L. and <em>Corchorus olitorius </em>L.), and they are cultivated in different south-east Asian countries including India and Bangladesh. Unfortunately, they are characterized by narrow genetic variability for adaptability to not only various agronomic environments, but also fibre yield, quality and susceptibility to diseases and pests. Therefore, research on genetic divergence in this crop is very important in formulating a successful breeding program for evolving cultivars superior in both yield and quality to cater to the increasing demand of value added jute products in the domestic and international markets. In our study, which was conducted at the Central Jute Research Experiment Station of Bangladesh Jute Research Institute (BJRI), during Kharif seasons of 2015.44 accessions of deshi jute (<em>Corchorus capsularis </em>L.) originated from different countries and two varieties CVL-1 and CVE-3 (developed from Bangladesh Jute Research Institute) as check were investigated to study the genetic variability, genetic diversity and degree of association of different component characters related to fiber yield. The seeds of experimental plant materials were grown in Randomized Complete Block Design with three replications. Statistical analysis was run to find out the genotypic and phenotypic variances, correlations and cluster analysis for fibre yield related traits namely technical height (m), leaf angle (dg), leaf length (cm), leaf width (cm), petiole length (cm), node no., base diameter (mm), middle diameter (mm), top diameter (mm), core diameter (mm), dry fibre weight (g), dry stick weight (g). Highly significant differences were observed among the genotypes for all the characters. Substantial amounts of genotypic variance were also obtained for all characters. Fibre weight was significantly and positively correlated with node no., base diameter, middle diameter, top diameter and core diameter. The clustering pattern revealed considerable amount of genetic diversity observed among the genotypes studied here and the accessions were grouped into five clusters. From two years’ evaluation it was revealed that the accessions 2512, 2445, 2749 and 2533performed better in most of the cases than the control varieties CVL-1 and CVE-3. These accessions may be used as parents for future variety development program.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>26-35, 2020</em></strong></p> 2020-07-22T06:25:49+00:00 ##submission.copyrightStatement## Physicochemical characterization of drinking water of selected regions in Bangladesh 2020-07-22T06:34:16+00:00 MM Hossain P Biswas MA Islam KF Usha S Marzia <p>Water, the most vital resources for the survival of life is of major importance not only to have an adequate and accessible supply, but also to have quality water that is considered safe for human consumption. The study was designed with a view to investigating water quality by assessing physicochemical properties of drinking water collected from selected regions and to compare the regional variation among the quality of water. The analysed physical properties were pH, electrical conductivity (EC), total dissolved solids (TDS) and the chemical properties were Iron (Fe) Lead (Pb), Sulphate (SO<sub>4</sub><sup>2-</sup>) and Phosphate (PO<sub>4</sub><sup>3-</sup>). Water samples were collected from separate point of tap water and tube well water and most of them were collected from restaurant, house hold and governmental office within the study areas. The result revealed:(a) the highest value for physical parameters pH, EC and TDS were 7.8, 723 µs/cm and535 mg/L respectively whereas for chemical parameters SO<sub>4</sub><sup>2-</sup>, PO<sub>4</sub><sup>3-</sup> and Fe it was 1.6, 0.53 and 1.1 mg/L respectively; (b) the lowest value for pH, EC and TDS were 6.9, 430 µs/cm and 180 mg/L respectively whereas for SO<sub>4</sub><sup>2-</sup>, PO<sub>4</sub><sup>3-</sup> and Fe it was 0.05, 0.04 and 0.05 mg/L respectively. All of them were present in water within the permissible limits except Fe (1.1 mg/L) and TDS (535 mg/L) as it exceeds WHO standards (0.3-1 mg/L) for Fe and (500 mg/L) for TDS (WHO, 2012). The result obtained for experimental parameters indicates that the water quality is slightly harmful for drinking purposes in terms of (Fe) household and (TDS) govt. office in some regions.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>36-44, 2020</em></strong></p> 2020-07-22T06:26:01+00:00 ##submission.copyrightStatement## Economic assessment of lemon-based agroforestry systems established in Madhupur Sal forest area of Bangladesh 2020-07-22T06:34:18+00:00 MK Hasan GMM Rahman R Akter SAK Hemel MT Islam <p>The study was carried out to determine the economic assessment of lemon-based agroforestry systems established in the Madhupur Sal forest during the period from May 2017 to September 2018. The study selected five lemon-based agroforestry systems viz. Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Banana-Aroid, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth and Lemon-Litchi-Papaya-Banana along with three replications having 0.13 ha area for each sample plot. The control plots (without lemon plant) for each of the five lemon-based agroforestry systems were also selected. In order to calculate the economic profitability of respective agroforestry systems as well as sole cropping performance, data related to incurred cost, total yield and income from lemon and crop components were collected through practical observation, key informant interview and focus group discussion. The benefit-cost ratio (BCR) and land equivalent ratio (LER) for each of the selected agroforestry systems were also determined. From the study, it has been found that all of the lemon-based agroforestry systems were profitable than their sole cropping in respect of income, BCR, and LER. The net profit (460032 Tk/ha) indicated that the Lemon-Litchi-Papaya-Banana based agroforestry systems were financially more profitable followed by Lemon-Pineapple-Papaya-Banana-Aroid, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. But the BCR and LER (3.515 and 1.73) revealed that Lemon-Pineapple-Papaya-Banana-Aroid based agroforestry system was more productive followed by Lemon-Litchi-Papaya-Banana, Lemon-Mango-Pineapple-Papaya-Ginger, Lemon-Pineapple-Papaya-Ginger, Lemon-Mango-Turmeric-Red amaranth based agroforestry systems. Prior to considering the obtained results from the study, it can be concluded that lemon-based agroforestry systems are more profitable than the cultivation of sole cropping.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>45-55, 2020</em></strong></p> 2020-07-22T06:26:09+00:00 ##submission.copyrightStatement## Soil characterization and fertility assessment of char lands for increased cropping intensity and crop productivity 2020-07-22T06:34:19+00:00 MM Ali MMA Tarafder N Mohsin MA Haque <p>A study was done for soil characterization and soil fertility assessment in <em>Char Latif </em>and <em>Char Monpura</em> of <em>Bhola</em> District to identify suitable crops for increasing cropping intensity and crop yields. The soils of <em>Char Latif</em> were almost silt loam to silty clay loam in texture. Soil pH values were slightly alkaline in reaction. The organic matter contents were low to medium (1.23-2.53%), the total N very low to low (0.08-0.22%), available P low to very low (4.67-14.1µg g<sup>-1</sup> soil), available S&nbsp; low to very high (4.02-156.8 µg g<sup>-1</sup> soil) and exchangeable K low to optimum (0.138-0.311%), exchangeable Ca and Na very high in <em>Char Latif</em> areas. At <em>Char Monpura</em> areas, the soils were silt loam to silty clay loam in texture. The soil pH was neutral to slightly alkaline in reaction. The organic matter contents of the soil were low to medium (0.21-2.60%) and the total N contents were very low to low (0.03-0.18%). Available P contents were very low (2.40-6.65 µg g<sup>-1</sup> soil). Available S contents were low to very high (4.02-156.8 µg g<sup>-1</sup> soil). Exchangeable K, Ca and Na contents were medium to optimum (0.20-0.48 me%), in desired level (4.54-9.07me%) and very high level (1.64-5.14me%), respectively. The soils of both <em>char</em> land areas were normally erosive having low fertility and low water holding capacity. Generally, farmers of char lands cultivated local varieties of crops. As a result, crop yields are low. High yielding profitable crops and crop cultivation measures could be recommended for both of the <em>Char Latif</em> and <em>Char Monpura</em> areas. The findings could help the government and the other organizations to take proper steps for improving livelihood of the char peoples by improved crop varieties and management practices. Hence, there is great opportunity to increase crop production through intensification of crop cultivation with the selection of appropriate crop varieties and soil management at char lands.</p> <p><strong><em>Progressive Agriculture 31 (1): </em></strong><strong><em>56-67, 2020</em></strong></p> 2020-07-22T06:26:18+00:00 ##submission.copyrightStatement##
