In Bangladesh, the typical land use structure is homestead agroforestry. It provides people with basic necessities like food, shelter, money, and other things. This study was regulated in the Nangalkot Upazila of the Cumilla district at Bangladesh to identify plant species grown in homestead areas and to explore the relationships between tree diversification and selected characteristics of farmers of the Nangalkot upazila. A total of 50 households from the small, marginal, medium, and large groups were polled. An interview schedule was created using a simple technique and questionnaire to collect data on the selected parameters. The respondents were chosen at random, and data were collected between January 1 and 21, 2021. For statistical analysis, the orthodox descriptive statistical parameters and Product Moment Correlation Coefficient of Pearson (r) were used. A total of twenty seven (27) plant species were identified in the study area's homestead, with 16 being fruit plants and 11 being forest plant species. The most abundant fruit species were mango, coconut, guava, papaya, jackfruit, etc., and the forest plant species were mahogany, bamboo, eucalyptus, neem, akashmoni, etc. On average, 14.38 plant species had been identified in respondents' homestead area. Sixteen agroforestry systems with four layers were identified from the study area. Selected farmers' characteristics, such as family size, farm size, homestead size, knowledge about homestead agroforestry, and socio-economic condition, showed a significant positive relationship with the total number of plant species, which can help in nutritional security of the people in the area of study. The current homestead agroforestry techniques in the Nangalkot Upazila of Cumilla district can be improved using advanced agroforestry approaches, and diversity of medicinal and multipurpose plants should be enhanced in order to maximize farmers' revenue.

The sheoak genera, Allocasuarina and Casuarina, contain a diverse range of Australian trees and shrubs of both ecological and economic importance. Although they are well known for tolerance to stressors such as drought, salinity and high temperatures, their tolerance to freezing has not been adequately examined. Some data has been published on the cold sensitivity of Casuarina cunninghamiana but other Casuarina spp. and no Allocasuarina sp. have been assessed. This study examined growth and survival of field-established Allocasuarina (2 species) and Casuarina (4 species) in Central Anatolia, Turkey with winter temperatures dropping to −15°C. Following establishment in May 2020, the accessions tested (100 plants in total) mostly grew well during summer and autumn in this semi-arid climate with mildly alkaline soil, but the shoots of all plants were killed by the extreme cold of winter, with only seven plants producing weak root sucking in the summer of 2021, which all subsequently died. Although both genera appear to be cold sensitive, the results indicate the merit for wider evaluation of sheoaks in other contexts with harsh environments but not in regions exposed to periods (even if relatively short) of subzero temperatures.

A field study was performed at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-station farm, Rangpur during Rabi season of 2021-22 to determine the effect of varieties and foliar application of boron on the growth and yield of green chili. The treatments were laid out in a Split-plot and replicated three times. Different concentrations of foliar Boron were applied as foliar sprays. The experiment comprised of nine treatments: T1= 0.5 g BL-1H2O at vegetative stage, T2= 1.0 g BL-1H2O at vegetative stage, T3= 0.5 g BL-1H2O at vegetative stage + 1.0 g BL-1H2O at Fruiting stage, T4= 1.0 g BL-1H2O at vegetative stage + 1.0 g BL-1H2O at Fruiting stage, T5= 1.5 g BL-1H2O at vegetative stage & T6= 1.5 g BL-1H2O at vegetative stage + 1.5 g BL-1H2O at Fruiting stage, T7= 2.0 g BL-1H2O at vegetative stage, T8= 2.0 g BL-1H2O at vegetative stage + 2.0 g BL-1H2O at Fruiting stage & T9 = Control and two chili varieties/lines viz. Binamorich-2 & RCL-1. From the present study, it was concluded that the highest fresh chili yield (18.11 tha-1) produced Binamorich-2 compared to RCL-1 which gave 14.52 tha-1. Among the nine treatments of foliar boron, B @ 2.0 g/L H2O at vegetative stage + B @ 2.0 g/L H2O at fruiting stage exhibited the highest fresh chili yield (21.22 tha-1). In respect of the interaction effect of foliar boron and variety, the Binamorich-2 was giving the highest fresh chili yield (25.00 tha-1). However, further research will be needed with different doses of foliar boron for promising production of chili at different locations of Bangladesh.
2021-22 年腊月期间，孟加拉国核农业研究所（BINA）在兰普尔（Rangpur）分站农场进行了一项田间研究，以确定品种和叶面喷施硼对青辣椒生长和产量的影响。试验采用分株法，重复三次。叶面喷施不同浓度的硼。试验包括九个处理：T1=无性期 0.5 g BL-1H2O，T2=无性期 1.0 g BL-1H2O，T3=无性期 0.5 g BL-1H2O + 果实期 1.0 g BL-1H2O，T4=无性期 1.0 g BL-1H2O + 果实期 1.0 g BL-1H2O，T5=无性期 1.5 g BL-1H2O & T6= 1.5 g BL-1H2O 在无性期 + 1.5 g BL-1H2O 在果期，T7= 2.0 g BL-1H2O 在无性期，T8= 2.0 g BL-1H2O 在无性期 + 2.0 g BL-1H2O 在果期，T9 = 对照和两个辣椒品种/品系，即 Binamorich-2 和 RCL-1。本研究得出的结论是，Binamorich-2 的鲜辣椒产量最高（18.11 吨-1），而 RCL-1 为 14.52 吨-1。在 9 个叶面喷硼处理中，植株期喷 B @ 2.0 g/L H2O + 果实期喷 B @ 2.0 g/L H2O 的辣椒鲜重产量最高（21.22 tha-1）。在叶面喷施硼与品种的交互效应方面，Binamorich-2 的鲜辣椒产量最高（25.00 tha-1）。不过，还需要进一步研究不同剂量的叶面喷硼，以提高孟加拉国不同地区的辣椒产量。

Climate change is one of the world's major issues and its impact particularly on migration is attracting increased attention for policymakers and experts. The purpose of this study was to assess the effects of climate change on human migration and to highlight the number of migrants in Bangladesh's coastal areas. The research was carried out in the Barishal division's Barguna, Barishal, Bhola, Jhalokati, Patuakhali, Pirojpur, and Khulna division's Khulna, Bagerhat, and Satkhira districts using focus group discussion (FGD), key informant’s interview (KII) and secondary data sources. The research findings are based on both primary data and secondary data gathered from various sources, which were conducted in nine coastal districts of Bangladesh from mid-February to mid-March 2020. This paper contains mapping by analyzing secondary information using ArcGIS 10 software of Geographic Information System technology. The study revealed the scenario of human migration and displacement in nine southwest districts due to different natural calamities like cyclones, riverbank erosion, floods, storm surges, and salinity intrusion. From household survey it was found that coastal erosion influenced about 74.73% people and floods forced only 3.51% of people to migrate. From 2014 to 2020, the highest and lowest disaster induced migrants have been found in 2017 and 2020. In addition, from 2014 to 2020, maximum and minimum migrants were in Barishal, and Jhalokati, separately in a row. In 2020, maximal and minimal number of migrants have been noted in Patuakhali and Satkhira with 38715 and 1900 migrants, respectively with the maximum disaster-induced migration in Barishal division. This research would be a great source of information for future investigations concerning human migration and displacement across the coastal districts of Bangladesh.
