An investigation was carried out to evaluate the effects of compost and compost tea made from agricultural waste rice straw on the yield and quality of two horticultural crops strawberry and tomato. In strawberry experiment, six treatments were considered which wereT<sub>1</sub>: 100% soil (as a control), T<sub>2</sub>: 80% soil + 20% compost, T<sub>3</sub>: 60% soil + 40% compost, T<sub>4</sub>: 40% soil + 60% compost, T<sub>5</sub>: 20% soil + 80% compost &amp; T<sub>6</sub>: 100% compost. Results revealed that number of fruit, fruit yield and total sugar (%)was increased with the increasing level of compost up to 80% after that decreased at 100% compost. The treatment T<sub>5</sub>: 20% soil + 80% compost gave the best results among the treatments to grow strawberry with good yield (185.3 g/plant) and sweetness (total sugar 5.19%). On the other hand, six treatments i.e. T<sub>1</sub>: Control, T<sub>2</sub>: Compost (5 t/ha), T<sub>3</sub>: Compost tea (50% concentration), T<sub>4</sub>: Compost (5 t/ha) + Compost tea (50% concentration), T<sub>5</sub>: Compost tea (100% concentration) and T<sub>6</sub>: Compost (5t/ha) + Compost tea (100% concentration) were considered in tomato experiment. As a result, it was observed that combined application of compost (5 t/ha) along with compost tea (100% conc.) (T<sub>6</sub>) gave the highest yield of tomato than not only control (T<sub>1</sub>) but also single application of compost or compost tea (T<sub>2, </sub>T<sub>3, </sub>T<sub>4</sub>&amp;T<sub>5</sub>). Level of compost tea concentration also showed significant effect on fruit yield of tomato. Comparing between treatment T<sub>4 </sub>and T<sub>6, </sub>fruit yield was found higher (1027.67 g/plant) in treatment T<sub>6</sub>: Compost (5t/ha) + Compost tea (100% conc.) than 961.3 g/plant in T<sub>4</sub>: Compost (5 t/ha) + Compost tea (50% conc.). So, it could be summarized that use of rice straw as compost and compost tea affects positively both in two experiments. The results of this study confirm the beneficial effects of compost to increase the yield and sweetness of strawberry and combination of compost and compost tea to increase the yield of tomato.</p> <p><strong><em>Progressive Agriculture 30 (4): 335-343, 2019</em></strong></p> 2020-04-29T00:00:00+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46890 Effects of different environmental pollutants on the anatomical features of roadside plants 2020-04-29T17:45:54+00:00 KJ Mitu aminmr64@yahoo.com MA Islam maislam@bau.edu.bd P Biswas aminmr64@yahoo.com S Marzia aminmr64@yahoo.com MA Ali aminmr64@yahoo.com <p>Experiments were conducted in order to investigate anatomical changes in leaves and stems of roadsides plants namely Mango (<em>Mangifera indica</em>), SilKoroi (<em>Albizia procera</em>) and Mahagony (<em>Sweatenia mahogany</em>). Plants that grown nearby roadside areas were exposed to various kinds of pollutants. To carry out the experiment, samples (Fresh leaves and Stems) were collected from two polluted sites and one control site. For anatomical study leaves and stems were cut into sections in the laboratory and changes were identified under the light microscopy. Results revealed that leaves of selected roadside plants had reduced cell size with black dot like substance deposited in the epidermis, palisade and spongy parenchyma in the polluted sites. But leaves of control site plants had normal anatomy. Meanwhile stem showed changes in vascular bundle of pollution affected sites but no change was found in control site. These results highlighted the importance of anatomical data for precious diagnosis of injury and to determine the sensitivity of roadside plants to different environmental pollutants.</p> <p><strong><em>Progressive Agriculture 30 (4): 344-351, 2019</em></strong></p> 2020-04-29T00:00:00+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46891 Effects of wastewater irrigation on soil physico-chemical properties, growth and yield of tomato 2020-04-29T17:45:57+00:00 KM Jahan aminmr64@yahoo.com R Khatun rehana_envsc@bau.edu.bd MZ Islam aminmr64@yahoo.com <p>The wastewater reuse for the purpose of irrigation may have a significant contribution to reduce water pollution, maximize water utilization and restore nutrient content of soils. An experiment was conducted at Environmental Science Field Laboratory, Bangladesh Agricultural University, Mymensingh from January to May, 2015 to investigate the effects of wastewater irrigation on soil physico-chemical properties (Soil texture, pH, electrical conductivity (EC), organic matter (OM), nitrogen (N), phosphorous (P), potassium (K), sulphur (S) and sodium (Na)) as well as yield and yield contributing characteristics of tomato crop. In this study, irrigation water, e.g., normal water, domestic wastewater, municipal wastewater and industrial wastewater was used as treatment with three replications. Soil and fruits were collected for analysis during last harvest. From the result, it is found that most of the chemical properties; OM, EC, N, K, S and Na contents were higher in wastewater treated soil compared to normal water irrigation. Among the treatments, plant height, LAI and yield were also higher in wastewater treated plot compared to normal water irrigated plot. Cost benefit analysis indicated that municipal wastewater irrigation gave more profit due to higher yield compared to domestic and industrial wastewater irrigation. From the study, it could be concluded that municipal wastewater irrigation was more profitable in respect of soil nutrient content and yield of tomato.</p> <p><strong><em>Progressive Agriculture 30 (4): 352-359, 2019</em></strong></p> 2020-04-29T00:00:00+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46895 Increasing cropping intensity of Fallow-Boro-T.

The present study was aimed at determining the effect of vernalization and doses of boron on seed yield and quality of summer onion. There were three vernalization treatments viz., no vernalization (control), vernalization at 10<sup>°</sup>C for 25 days and vernalization at10<sup>°</sup>C for 40 days and four boron treatment viz., 0 kg ha<sup>-1</sup>, 1 kg ha<sup>-1</sup>, 2 kg ha<sup>-1</sup> and 3 kg ha<sup>-1</sup>. The two-factor experiment was laid out in the Randomized Complete Block Design with three replications. The results of the experiment showed that the vernalization had significant and positive influence on all the parameters studied. Boron had also significant effects on all the parameters. Interaction between vernalization and boron was significant on all the yield and yield contributing parameters. The highest seed yield (191.01 kg ha<sup>-1</sup>) was obtained from vernalization at 10<sup>°</sup>C for 40 days and lowest (137.88 kg/ha) from control. The highest seed yield (255.38kgha<sup>-1</sup>) was obtained from 3 kg ha<sup>-1</sup> boron and lowest (83.48 kg ha<sup>-1</sup>) from control. When combined effect was considered the highest seed yield (293.36 kgha<sup>-1</sup>) was obtained from vernalization at 10<sup>°</sup>C for 40 days with 3 kg ha<sup>-1</sup> boron.

The experiment consisted of three cultivars viz.&nbsp; BR11, BRRI dhan33 and BRRI dhan49 and five marshpepper crop residues treatment such as 0, 1.0, 2.0, 3.0 ton ha-1&nbsp;and hand weeding. The experiment was laid out in a randomized complete block design (RCBD) with three replications. Five weed species belonging to four families infested the experimental plots. Weed population and weed dry weight were significantly affected by cultivar and crop residues treatment. The highest percent inhibition of all the studied weed was found by hand weeding. The second highest percent weed inhibition was found with the application of marshpepper residues at 3.0 t ha-1 which was 63.43, 63.43, 52.85, 52.40 and 59.12 percent for sabuj nakful (<em>Cyperus difformis</em>), chesra (<em>Scirpus juncoides</em>), shama (<em>Echinochloa crusgalli</em>) panikachu (<em>Monochoria vaginalis</em>) and panishapla (<em>Nymphaea nouchali</em> ) respectively. The maximum weed growth was noticed with the cultivar BRRI dhan33 variety and the minimum was found in the cultivar BRRI dhan49. The grain yield as well as the yield contributing characters produced by BRRI dhan49 was the highest among the studied varieties. The highest reduction of grain yield was obtained in no crop residue treatment. The highest number of effective tillers hill-1, number of grains panicle-1, 1000-grain weight, grain and straw yields were observed in marshpepper residues in hand weeding followed by 3.0 t ha-1 marshpepper crop residue. BRRI dhan49 produced the highest grain and straw yields under hand weeding followed by marshpepper residues 3.0 t ha-1 treatment. Results of this study indicate that marshpepper residues showed potentiality to inhibit weed growth and it has a significant effect on the yield of transplant <em>aman </em>rice. Therefore, marshpepper residues might be used as an alternative way for weed management effective and sustainable crop production.</p> <p><strong><em>Progressive Agriculture 30 (4): 379-386, 2019</em></strong></p> 2020-04-29T17:41:56+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46898 Value chain analysis of tilapia fish seed in some selected areas of Mymensingh district in Bangladesh 2020-04-29T17:45:51+00:00 MM Rahman aminmr64@yahoo.com N Tabassum aminmr64@yahoo.com SA Sabur aminmr64@yahoo.com DZ Ethen ethen@bau.edu.bd EJ Mahfuza aminmr64@yahoo.com <p>Fisheries sector plays an important role in the economic development of Bangladesh due to its commercial and nutritional value. In Bangladesh, tilapia is produced in a wide range of culture systems, including small-scale, low-input, rural ponds, semi-intensive, intensive and commercial operations. Fish seed is the major input for producing tilapia. So this study is an attempt to examine the prevailing tilapia fish seed value chain based on primary data collected from 45 respondents from the Mymensingh District. Fifteen (15) hatchery owners, ten (10) <em>paikers</em>, ten (10) wholesalers and ten (10) retailers were selected from the study areas. All these value chain actors perform their marketing functions in Dhalla bazar in Trishal, Gouripur bazar in Gouripur, Ishwarganj bazar in Ishwarganj and Digharkanda mor in Mymensingh Sadar. The data were collected through the direct interview method with the help of pretested questionnaires during September to October 2018. The total cost per 10000 pieces tilapia fingerlings was Tk. 2133.28 and net return was calculated at Tk. 1573.85 by the hatchery owners. In the value chains, the highest sale price per 10000 pieces fingerlings received by the retailer was Tk. 7220.13 and the lowest sales price received by paiker was Tk.5185.80 for Tilapia fish seed. Among all the intermediaries, the highest value addition was 36.32 percent by <em>paiker</em> and the lowest value addition was 18.37 percent by retailer. However, net margin was higher for <em>paikers</em> (Tk. 1231.84) and lower for retailers (Tk. 760.97).</p> <p><strong><em>Progressive Agriculture 30 (4): 387-394, 2019</em></strong></p> 2020-04-29T17:42:11+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46900 Yield gap, profitability and inefficiency of Aman rice in coastal areas of Bangladesh 2020-04-29T17:45:55+00:00 AC Roy roycomma@gmail.com MA Rahman aminmr64@yahoo.com MA Khan aminmr64@yahoo.com <p>Despite of being an extremely overpopulated country with a limited land resource, Bangladesh has managed to increase its food production to a viable level. Yet it is necessary to increase production of food crop in order to cope with the growing population in a sustainable way. Closing yield gap is a means of attaining sustainability of agricultural intensification to keep pace with the growing crop demand. The objective of the present study is to assess the inefficiency and the yield gap of Aman rice production in climate vulnerable areas in Bangladesh. The study was conducted in Shaymnagar and Kaliganj Upazilas of Satkhira district in Bangladesh and data were collected using a stratified random sampling technique from 110 Aman cultivating farmers. Descriptive statistical techniques as well as Stochastic Frontier model were used to achieve the objectives of the study. The study revealed that, Aman rice cultivation was profitable in the study area. We estimated the model based yield gap, highest recorded yield gap and experimental yield gap. The mean efficiency analysis revealed that farmers could increase their production with optimal use of inputs and proper management systems. Absence of proper knowledge about the optimum input use and lack of institutional training as well as inadequate extension services were responsible for the reduced yield in most farmers’ fields. Salinity has reduced the overall productivity of the region, but it is believed that by popularizing the practice of saline tolerant rice variety and addressing the above mentioned issues the potential production can be achieved in the coastal region.</p> <p><strong><em>Progressive Agriculture 30 (4): 395-404, 2019</em></strong></p> 2020-04-29T17:42:38+00:00 ##submission.copyrightStatement## https://www.banglajol.info/index.php/PA/article/view/46901 Techno-economic performance of mechanical transplanter for hybrid variety of rice in unpuddled soil 2020-04-29T17:45:52+00:00 MS Basir aminmr64@yahoo.com M Ashik-E-Rabbani ashiks424@yahoo.com S Sarkar aminmr64@yahoo.com MM Alam aminmr64@yahoo.com <p>Unpuddled transplanting of rice as a part of conservation agricultural practice has become significant due to its protective behavior for soil properties and economic profitability. Mechanical transplanting in unpuddled soil using hybrid rice variety leads to a high yield with minimum transplanting time and cost, securing soil nutrients. A study was conducted in Bangladesh Agricultural University to evaluate the efficacy of mechanical transplanting of hybrid rice in unpuddled soil considering field and financial performances of rice transplanter. The experiment was conducted during <em>Boro</em>-2018 season with a Daedong DP-480 rice transplanter. Hybrid rice seed Moyna (HTM303) of Laal Teer seed company Ltd. was used for transplanting at a seed rate of 120g per tray and seedling per hill was adjusted to 2-3 nos. In unpuddled soil, transplanter possessed an effective field capacity, fuel consumption and efficiency of 0.16 ha/h, 4.8 l/ha and 67.48%, respectively. Transplanting time included an idle time of 11% due to clogging with mud. Missing hill percentage was found as 6.1% with a floating hill of 7.36%. Plant heights were 15.72 cm and 86.19 cm at the day of transplanting and at the day of harvesting, with tiller per hill of 18 nos. The average panicle length of plants was found as 23.6 cm where traditionally transplanted rice has panicles of 21.2 cm average. The yields of mechanically transplanted rice in unpuddled soil condition was 5.21 ton/ha and the yield of mechanical transplanted rice in unpuddled soil was found to be 27.07% higher than traditionally transplanted rice. The BCR and IRR of mechanical transplanting in unpuddled soil was found 1.57 and 55% considering 10% discount factor. The payback period, after which the transplanter will overcome its costs, was found 1.68 years. Financial analysis reveals that mechanical transplanting with this field capacity will be beneficial if the transplanter is used to transplant 19.77 ha annually.</p> <p><strong><em>Progressive Agriculture 30 (4): 405-413, 2019</em></strong></p> 2020-04-29T17:42:51+00:00 ##submission.copyrightStatement##
