Both waterlogged and non-waterlogged mungbean plants were received varying doses of rescue nitrogen from urea fertilizer. The rescue nitrogen (N) treatments were: N0-no rescue N; N<sub>30</sub> - 20 and 10 kg ha<sup>-1</sup> rescue N applied at 0-day and 15-day after removal of waterlogging (ARW); N<sub>40</sub> - 30 and 10 kg ha<sup>-1</sup> rescue N applied at 0-day and 15-day ARW and N<sub>50</sub> - 40 and 10 kg ha<sup>-1</sup> rescue N applied at 0-day and 15-day ARW. The study was laid out in a randomized complete block design with four replications. Different levels of rescue N improved plant height, leaf chlorophyll index, phonological period, plant growth, pod formation and seed yield of mungbean. N-treated plants showed higher relative SPAD chlorophyll values and the increment was higher for higher N-dose. Waterlogging reduced 40% root dry matter and 34% both shoot and total dry matter relative to non-waterlogged plants. Rescue N significantly increased both the root and shoot dry matter. The waterlogged plants without rescue N showed 29% reduction in the number of pods per plant and the reduction showed 13% for rescue N40 in waterlogged plants. The seed yield reduction was 25% in waterlogged plants without rescue N but with rescue N, seed yield remarkably increased particularly in N<sub>40</sub>-treated plants. Therefore, the study suggests that rescue N fertilizer application may be a viable practice in improving waterlogging tolerance and increasing yield of mungbean.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 01-13</p> Md Rafiqul Islam, Mehfuz Hasan, Munny Akter, Nazmun Nahar Shibly ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Effect of Cropping System and Rice Residue Retention on Crop Productivity and Soil Physical Properties in Rice Based Cropping System of Bangladesh <p>Cropping systems of Bangladesh are highly diverse and cultivation costs of puddled transplanted rice (PTR) are high. Therefore, an improved system is needed to address the issues, a field experiment was conducted during 2011-2013 to evaluate system intensification with varying degrees of cropping systems and residue retention. Four cropping systems (CSE) namely CSE1: T. <em>boro </em>rice-T. <em>aman </em>rice (control), CSE2: wheat-mungbean-T. <em>aman </em>rice (wheat and mungbean sown using a power tiller-operated seeder (PTOS) with full tillage in a single pass; puddled transplanted <em>aman</em>), CSE3: wheat-mungbean-dry seeded DS <em>aman </em>rice (DSR), and CSE4: wheat-mungbean-DS <em>aman </em>rice (all sown by PTOS with strip tillage) were compared. Two levels of <em>aman </em>rice residue retention (removed; partial retention i.e. 40 cm of standing stubble) were compared in sub plots. Grain yield was significantly higher (by 11%) when wheat was grown after DSR than PTR. Similarly, PTR and DSR (<em>aman </em>rice) produced statistically similar crop yields. Rice residue retention resulted a significantly higher (by 10%) wheat yield and a slightly increased (by 6%) mungbean yield than that of residues removed. The system productivity of CSE4 was significantly higher (by 10%) than CSE1 when averaged of the two years data. Partial <em>aman </em>residue retention gave significantly higher system yield than residue removal (by 0.6 t ha<sup>-1</sup>). After two years, no effect of CSE or partial <em>aman </em>residue retention was found on soil physical property (bulk density) of the top soil. Therefore, CSE4 along with residue retention would be more effective for sustainable crop production.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 14-30</p> M Jahangir Alam, S Ahmed, MK Islam, R Islam, M Islam ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Assessing Profitability, Marketing Activities and Problems in Modern Rice Production in Two Northern Districts of Bangladesh <p>This study estimated the cost and revenue of BRRI dhan 28 productions in two districts namely, Bogura and Gaibandha in Bangladesh. The paper also identifies farmers marketing activity and their production problems. Primary data were collected from 60 farm household’s survey using pretested semi-structured questionnaire during November to December, 2017. Farm level production and profitability were analysed by using net farm incomes and Benefit Cost Ratio (BCR) taking into account the variable cost and total cost. Applying descriptive statistics, the analysis showed that total cost of paddy production was higher in Bogura (BDT 44,555.3/acre) compared that of Gaibandha (BDT 42,199.5/acre) while net farm income was higher in Gaibandha (BDT 32992.2/acre) than Bogura (BDT 32475.9/acre). The analysis further showed that paddy production was profitable in both districts. BCR on the basis of variable cost and total cost indicated that return from paddy production was higher than cost which also ensures farmers profit in paddy production in both the districts. According to farmers’ opinion, disease infestation was the major production problem in Bogura district while both disease attack and natural calamities were the major production problems in Gaibandha district. Farmers’ suggested to reduce the cost of pesticides and they need marketing facilities to sell their product. They also suggested to establish cold storage facilities which create the opportunity to get fair price for their product.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 31-40</p> AH Siddiquee, HM Sammy, MR Hasan ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Consumer Preference for Sea Fish Consumption in Dhaka City of Bangladesh <p>Fish is traditionally complemented to rice in the diet of Bangladeshi. Thus, its daily consumption is pretty normal. Although, a number of researches have been done on river fish and its consumption, there seems a few in the public that specifically studied consumer preference for sea fish consumption in Bangladesh. This study, therefore, explores the consumers’ preference for sea fish consumption in Dhaka city of Bangladesh. A cross sectional survey design was followed to collect data from 120 respondents in four quota sampled areas of the city, namely; Uttara, Khilkhet, Mirpur and Jatrabari. The results revealed that 20 species of sea fish were usually brought to the markets patronised in the selected areas, but 17 were commonly consumed. The consumers mostly preferred <em>Tenualosa ilisha </em>(95.83%), <em>Pampus chinensis </em>(91.67%), <em>Penaeus monodon </em>(75.0%), <em>Lates calcarifer </em>(74.17%), <em>Euthynnus affinis </em>(62.5%) and <em>Harpadon nehereus </em>(58.33%) for their taste whereas, Pama <em>pama </em>(33.33%) and <em>Setipinna taty </em>(46.67%) were preferred for lower price. The average monthly household sea fish consumption was 5.49 kg. Age, level of education, gender, annual income and religious view were found to have significant positive association with household sea fish consumption. Respondents preferred sea fish for health benefits related to heart, eye-sight, nutrient enrichment, diseases protection and prevention of depression. However, irregular supply of sea fish and higher price were pointed by the respondents as the main constraining factors to sea fish consumption. Generally, Bangladesh is blessed with vast sea fish resources, but consumers’ accessibility need to be strengthened.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 41-51</p> Md Enamul Haque, Shahnaz Khanom, Md Safiul Islam Afrad, Aliyu Akilu Barau, SM Rafiquzzaman ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Morpho-Physiology and Anatomical Responses of Sorghum Seedlings as Affected by Salinity in Hydroponic Culture <p>An experiment was conducted at the growth chamber of Department of Crop Botany in the Bangladesh Agricultural University, Mymensingh, Bangladesh during March 2018 to observe morpho-physiology and anatomical response of sorghum. Six genotypes were grown in hydroponics with a full nutrient solution (NH4NO3-500 μM; Ca(NO<sub>3</sub>)<sub>2</sub>-500 μM; MgSO<sub>4</sub>-200 μM; KH<sub>2</sub>P0<sub>4</sub> -100 μM; FeC1<sub>3</sub>-2μM; H<sub>2</sub>B0<sub>3</sub>-11 μM; MnC1<sub>2</sub>-2μM; ZnC1<sub>2</sub>-0.35μM; CuCl<sub>2</sub>-0.2μM; (NH<sub>4</sub>)<sub>6</sub>Mo<sub>7</sub>0<sub>4</sub>-0.1 μM) and 100 mM salinity was imposed on 14 days seedlings. Data on morpho-physiological and anatomical parameters from seedlings were collected after 21 days and stress tolerant indexes of shoot and root were analyzed. Anatomical parameters like metaxylem and protoxylem thickness were also investigated. The results indicated that all the parameters <em>viz. </em>root length, shoot length, fresh and dry weight of shoot and root, stress tolerance index of root, and shoot, dry weight of shoot and root, relative chlorophyll content, photochemical efficiency (Fv/Fm), proline concentration, total root area, vascular cylinder area and root diameter were decreased with increasing salinity levels except leaf proline content. Genotypes BD 750 and BD 686 showed better performance considering tolerant indicators while the poor performance was exhibited by BD 747 and BD 753. Thus, based on overall observation BD 750 and BD 686 might be salt tolerant.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 52-65</p> MN Sarkar, AKMZ Hossain, SN Islam, S Shahanaz, MZ Tareq ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Morpho-physiological Response of Gliricidia sepium to Seawater-induced Salt Stress <p>Soil degradation due to the contamination of excessive saline water has been threatening soil health vis a vis plant productivity worldwide. <em>Gliricidia sepium</em>, a fertilizer tree, has come into limelight in recent decades in Bangladesh due to its potency in improving soil fertility. However, study on its suitability in coastal areas alongside identifying the salt-endurance limit is still lacking. Therefore, morpho-physiological attributes of <em>G. sepium </em>under seawater-induced different levels of salt stress were analyzed in a pot experiment from March to May 2018 to gain an insight into its salt-adaptive mechanisms. Results revealed that seawater-induced salinity negatively affected the growth-related attributes, such as plant height, fresh weight of shoots, dry weights of shoots and roots, and leaf area. The reduction of growth was coincided with reductions in photosynthetic pigments and relative water content. Interestingly, salt tolerance index was not decreased in parallel with increasing dosages of seawater, indicating the salt tolerance capacity of <em>G. sepium</em>. Furthermore, enhanced accumulation of proline increased the osmoprotective capacity of <em>G. sepium </em>in order to overcome the salt-induced osmotic stress. The results of the present study concluded that <em>G. sepium </em>might be suitable for growing in the salt prone areas ranging 20 – 40 dSm<sup>-1</sup>.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 66-75</p> MA Rahman, AK Das, SR Saha, MM Uddin, MM Rahman ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Biochar on Soil Fertility and Crop Productivity <p>An experiment was conducted at the farmer’s field in Shibalaya upazilla of Manikganj district during rabi season of 2017to study the effectiveness of biochar on soil fertility and yields of brinjal and cauliflower. There were five treatments viz. control, recommended inorganic fertilizer (RF), biochar 1 t/ha + RF, biochar 3 t/ha + RF and biochar 5 t/ha + RF laid out in a randomized complete block design with four replications. Data revealed that biochar at the rate of 5 t/ha along with RF provided maximum yields of brinjal (67 t/ha) and cauliflower (42 t/ha). The pH, nutrients and moisture contents of the study soils increased and bulk density decreased with the higher rates of biochar application. Significant changes were observed in the total organic carbon in soils which increased by 25 to 41% from the initial levels. Recovery, agronomic and physiological efficiencies of N, P, K and S were found the highest with the application of biochar 5 t/ha. In terms of soil fertility and crop productivity application of biochar was found promising and can be recommended as an effective soil management practice.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 76-88</p> Md Mojammel Haque, Md Mizanur Rahman, Md Monjur Morshed, Md Shafiqul Islam, Md Safiul Islam Afrad ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Evaluation of Blackgram (Vigna mungo L.) Genotypes for their Tolerance to Flooding <p>Waterlogging is one the major abiotic stresses that affects growth and yield of blackgram. A field experiment was carried out at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, 1706 during kharif II season to evaluate 26 blackgram genotypes for understanding the flood tolerance in respect of yield and yield contributing characters. The experiment was laid out with a randomized complete block design with three replications. Water logging depth was 3-5 cm, created by irrigation from tap water and imposed at 29 days after emergence of seedlings which was maintained for 8 days. Multivariate analysis was performed involving eight qualitative plant characters. A wide range of variation was found for all the qualitative plant characters like plant height, plant dry weight, branches per plant, pods per plant, pod length, seeds per pod, 1000-seed weight and yield per plant. Flooding reduced all the growth parameters of blackgram but degree of reduction varied greatly over the blackgram genotypes. Considering yield performance, the genotypes BU Acc 25 showed the highest yield per plant (9.03 g) followed by the BU Acc 17 (6.47 g) and BU Acc 24 (6.17) under flooding . The yield reduction percent of the same genotypes were minimum (43.86, 60.82 and 65.96, respectively) compared to control which is very important for selection of those genotypes as a flooding tolerant.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 89-101</p> MS Rana, MA Hossain, TA Urmi, S Ahmed, MM Haque, MM Islam ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 Comparative Performance of Honey Production from Two Different Bee Hives in Bangladesh <p>The study was conducted in three districts viz., Sirajgonj, Gazipur and Satkhira during the mustard, litchi, and mangrove blooming period, respectively during 2015-2016 and 2016-2017 cropping seasons to study honey production efficiency of traditional hive and poly super hive. The study was carried out in paired plot design. Fourteen boxes were used in each setup, among them seven were traditional hive and seven were poly super hive. In Ullapara of Sirajganj district during 2015-16 poly super hive yielded the highest (17.03 kg hive<sup>-1</sup>season<sup>-1</sup>) honey. In 2016-17 (mustard) the highest honey was harvested from poly super hive operated at Tarash (18.63 kg hive-1season<sup>-1</sup>) and the lowest honey yielded in poly super hive at Shahjadpur. At Kapasia of Gazipur during 2015-2016 (litchi) the poly super hive produced the highest (20.46 kg hive<sup>-1</sup>season<sup>-1</sup>) honey yield cropping season and the lowest (20 kg hive<sup>-1</sup>season<sup>-1</sup>) was in Kaliganj (Gazipur district). On the other hand, during 2016-2017 it was observed that in poly super hive produced the highest (14.92 kg hive<sup>-1</sup>season<sup>-1</sup>) honey operated in Gazipur Sadar and the lowest (13.93 kg hive<sup>-1</sup>season<sup>-1</sup>) was in Kaliganj. In Satkhira during 2015-16 cropping season (mangrove) the poly super hive gave the highest (14.92 kg hive-1season<sup>-1</sup>) honey yield and it was obtained from Tala and the lowest (14.65 kg hive<sup>-1</sup>season<sup>-1</sup>) honey was yielded and it obtained in Kaliganj. Again during cropping season 2016-17 poly super hive produced the highest (12.5 kg hive<sup>-1</sup>season<sup>-1</sup>) honey and it was from Tala and the lowest (11.45 kg hive<sup>-1</sup>season<sup>-1</sup>) in Munshiganj. There was significantly less honey production was recorded in traditional bee hives than the poly super hive. During 2016-17 season honey production was higher than 2015-16 season at Sirajganj. However, opposite result was observed at Gazipur and Satkhira.</p> <p><em>The Agriculturists </em>2019; 17(1-2) 102-111</p> Mohammed Sakhawat Hossain, Md Mohi Uddin Fazlullah, Md Mizanur Rahman ##submission.copyrightStatement## Thu, 26 Dec 2019 00:00:00 +0000 A Note on Marine and Estuary Fish Habitat, Prices and Supply in Different Markets of Dhaka City <p>This paper analyses the available marine fish of Bay of Bengal and other coastal areas of Bangladesh and its supply in Dhaka city.
