This study was thus conducted in pots inside semi-controlled vinylhouse to assess the effect of water stress on growth and yield of some popular mungbean varieties, viz. BUmug 2, BUmug 4, BARI Mung-5, BARI Mung-6, Binamoog-5 and Binamoog-8. Two water regimes, 80% field capacity (FC; non-stress) and 50% FC (water stress) were maintained. The experiment was laid out in a completely randomized design having four replications. Under water stress the variety Binamoog-5 had the largest leaf area (850.4 cm2 ), while BUmug 4 had the smallest (695.1 cm2 ). At maturity the reduction of shoot dry weight due to water stress was the highest in BUmug 4 (20.6%) while that was the lowest in Binamoog-5 (12.5%). The highest reduction of pod number due to water stress was recorded in BUmug 4 (45.1%) and the lowest was in Binamoog-5 (32.9%) followed by Binamoog-8 (34.5%). The highest reduction in seed number pod-1 due to water stress was in BUmug 4 (21.8%) and the lowest was in Binamoog-5 (16.79%). Water deficit did not exert significant effect on 100-seed weight in the varieties except BUmug 4. Binamoog-5 had the maximum yield plant-1 under both control (12.8 g) and water deficit (7.4 g) conditions followed by Binamoog-8, while BUmug 4 had the lowest in both control (11.6 g) and water deficit (6.3 g) conditions. It was concluded that Binamoog-5 and Binamoog-8 can be potential varieties for field trial for cultivation under water deficit conditions.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"143 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78532114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Farmers in Bangladesh mainly apply conventional synthetic insecticides to protect crops from the attack of these pests. The current study was conducted in the experimental field of the Department of Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during March 2021 to July 2021 to know the effects of five biorational insecticides, namely Biotrin (matrine), Proclaim (emamectin benzoate), Sunmectin (abamectin), Mahogany oil and Neem oil on the abundance and infestation of red pumpkin beetle and fruit fly infesting ash gourd. The insecticides were applied 3 times maintaining 7 days interval. Results showed significant reduction of the insect population compared to untreated control. Sunmectin (1.55±0.34) treated plot showed the lowest abundance of red pumpkin beetle after the 3rd spray with 65% reduction of population compared to untreated control plot. Biotrin (8.59±1.00%) treated plot showed the lowest leaf and flower infestation by red pumpkin beetle after 3rd spray, with the reduction (69% in both) over control. The lowest fruit infestation was found in Sunmectin treated plot (23.01±8.05%). The highest yield of ash gourd (17.9 T/ha) was recorded from Sunmectin treated plot which showed statistical similarity to Proclaim (16.01 T/ha) and Biotrin (15.90 T/ha) treated plots with 3.5, 2.5 and 2.6 benefit cost ratio, respectively.

The nymph and adults suck cell sap from the underside of the leaves and secret honeydew that develop sooty mold fungi and interfere the growth of the plants. It was first identified in Bangladesh in 2019 on coconut plants in Jashore.Then it has spread to almost all other districts in Bangladesh. Highest coconut tree infestation was observed in southwestern part (97.5%) and lowest (68.0%) was in central part of the country and there was no significant difference among locations. In the coastal regions, the highest percent (97.0%) of infested coconut tree, infested fronds (96.2%) and leaflet area (84.0%) was recorded in Bagerhat district while the lowest percent infested tree (68.0%), fronds per tree (67.2%) and leaflet area (48.0%) was in Cox’s Bazar. The abundance of RSW increases as the number of leaves increased. Higher percent tree infestation (85.7%) was noticed in native while it was lower(81.2%) in dwarf coconut plants although no significant difference was observed.Low abundances of adult RSW were also found in dwarf coconut plants than that of native ones.

The study was conducted from March to October, 2019 by a questionnaire survey and socio economic study of the fishermen in the Chudanga district. However, fish bio-diversity has rapidly declined in the Mathabhanga River. In this study, 44 fish species were found in the Mathabhanga River belonging to eight orders, 18 families and 29 genera. According to the IUCN Red List, 24.99% of fish species were threatened. Among the threatened species, 13.63% were vulnerable, 9.09% endangered and 2.27% were critically endangered. About 45% of fishermen were illiterate and housing condition of fishermen were dominated by tin-shed with bamboo (65%). A significant proportion of fishermen depend upon village doctors (62%) and 86% of the fishermen were far from power plants. Majority (45%) of fishermen were landless and 75% of fishermen were engaged in fishing as their main occupation whereas 65% of the fishermen had annual income between Tk. 35000 to Tk. 55000. In addition, overall values of diversity richness and evenness indices were found 1.12, 4.99 and 0.57,for vulnerable, endangered, and critically endangered species, respectively. These results indicated that dam construction and other human activities have seriously destroyed the fish habitat and led to the decline in fish diversity. Therefore, the conservation of fish has become urgent in the Mathabhanga River, and an integrated management plan should be developed and effectively implemented.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84148831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 64 dairy cows of different genetics were selected for the study. All the cows were divided into four different groups and each group consists of 16 cows, namely Local (L), Local ×Holstein Friesian (L×HF), Local × Sindhi (L×S) and Local ×Sahiwal (L×SA). Each group of dairy cows were again subdivided into two subgroups like control and DCP supplement group. We assessed the productive performances such as milk production and lactation length, as well as reproductive performances such as service per conception, post-partum heat period and calving intervals among different breeds of cows as well as in the matching DCP supplement group. The productive performance among the different groups of cows i.e. L×HF, L×S, L×SA and Local cows were found significantly (p<0.01) different. Interestingly, DCP supplement group showed a significant increase of productive performances compared with the control group. Likewise, reproductive performance such as service per conception in different crossbred and Local cows also decreased significantly (p<0.01) with DCP supplement group than the control. Contrarily, the post-partum heat period and calving intervals in different crossbred and Local cows were slightly lower in the DCP supplemented group than control that did not differ significantly. Therefore, the study reveals that L×HF crossbred were found to be better performer followed by L×SA, L×S and Local cows, and DCP supplementation improve all the parameters studied irrespective of genetic variation.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73390521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
