The present study is an attempt to examine the socioeconomic characteristics and compared profitability analysis of both IPM and Non-IPM vegetable growers, and to identify the problems faced by vegetables growers in use of IPM practices in some selected areas of Kishoreganj district. A total of 45 farmers were purposively selected where three different IPM practices were taken into consideration. To get a more complete picture of vegetable production using both IPM and non-IPM technology, the socio-economic profile of farmers was examined and compared. The study found that IPM farmers were in better-off condition than that of non-IPM farmers in all types of socioeconomic characteristics. The major findings of the study revealed that production of all the selected vegetables were profitable for both IPM and non-IPM farmers. But, IPM based cultivation was more profitable than that of non-IPM based cultivation. Average total costs were Tk. 86352.8 and Tk. 100061.5 for IPM and non-IPM farmers, respectively. Average gross returns were Tk. 257293.3 and Tk.235788.8 for IPM and non-IPM farmers, respectively. The average net return for IPM farmers was Tk.170940.5 and for non-IPM farmers it was estimated at Tk. 135727.3. The average benefit cost ratio for IPM farmers was 2.9 and for non-IPM farmers it was estimated at 2.3. Most of the farmers were in the categories of low to medium problem confrontation in using IPM practices. The first ranked constraint is lack of training facility. Thus, massive extension facility including training is needed in the study areas to increase the extent of use of IPM technology.Progressive Agriculture 27 (3): 311-319, 2016

The study was undertaken to identify the core contribution of women in the rice production activities, identify the wage gap between male and female laborer and factors influencing womens participation in rice farming at household level in Bangladesh. In doing so, the study utilized the data collected by the field survey from Nilphamari and Mymensingh districts of Bangladesh. A total number of 60 women respondents were selected using random sampling methods who were actively working in the rice fields during the production period in 2015. Data were analyzed using simple statistical techniques as well as OLS regression analysis. An analysis of the socioeconomic status of the women showed that in terms of contribution, nearly 43% and 42%of the total works were done by rural women in rice farming activities in Nilphamari and Mymensingh district, respectively. It was found that male workers spent 228.2 hours and female workers 174.5 hours per season in Nilphamari region compared to 270 hours and 197.3 hours per season in Mymensingh region, respectively. The average wage rate in Nilphamari district was BDT 241/day for male and BDT 175/day was female. Similarly, in Mymensingh district the average wage rate for male and female workers was BDT 281/day and BDT 162/day, respectively. The result of the OLS method suggests that the distance of the rice field from the home, the number of available technologies used and the number of adult male labour significantly affect the women's participation in farming activities. Despite the positive role of women in the production activities, their contribution was often neglected in terms of wage rate. Therefore, this study recommends the avoidance of wage discrimination between male and female workers which may strengthen their position within the family and increase their self-esteem and status in the society.Progressive Agriculture 27 (2): 180-188, 2016

The present study was designed to analyze the production, cost, return and profitability of three winter vegetables (brinjal, country bean and cabbage) production of three villages ofNarshingdi District in Bangladesh. To achieve the objectives, data were collected from 60 farmers. The sample farmers were selected through purposive sampling technique.The major findings of the study were: among the winter vegetables, cabbage production was more profitable. Per hectare profitability of growing vegetables from the viewpoints of individual farmers was measured in terms of gross return, gross margin and value addition. Per hectare gross costs of brinjal, country bean and cabbage production were Tk. 241277, Tk. 162337 and Tk. 204152 respectively, and per hectare average yields of brinjal, country bean and cabbage were estimated at 24175 kg/ha 15774 kg/ha, and 24707 kg/ha, respectively. Per hectare gross returns of brinjal, country bean and cabbage were Tk. 483500, Tk. 347028 and Tk. 494140, respectively. Per hectare net returns of brinjal, country bean and cabbage were Tk. 242223, Tk. 184691, and Tk. 289988, respectively. It shows that cost of production per hectare was higher for brinjal than for cabbage and country bean. The study also shows that per hectare yield, gross returns, gross margin, net return and benefit cost ratio of cabbage were higher than those of country bean and brinjal. Therefore, it is clear that cabbage production was most profitable among the three crops.Progress. Agric. 2014. 25: 47-53

- Abstract
An accurate, cost-efficient, and early crop yield projection is a national and global necessity. This study is aimed to achieve the national demands by proposing crop yield estimation models on the Google Earth Engine (GEE) platform. This study directly used dynamic crop phenology metrics to model soybean crop yield by considering climatic regions in the USA (e.g., Central, East, Northeast, South, Southeast, and West North Central regions). We modeled soybean yields with vegetative growth metrics (VGMs) of NDVI narrated as VGM70 (avg. NDVI of 70 days from the emergence), VGM85 (avg. NDVI of 85 days from the emergence), VGM98T (total NDVI of 98 days from the emergence), VGM120 (avg. NDVI of 120 days from the emergence), VGM
mean (avg. NDVI of the growth season), VGMmax (maximum NDVI of the growth season), and climatic factors (i.e., daytime surface temperature: DST, night-time surface temperature: NST, and precipitation) from 2000 to 2019. This study further explored individual predictors and a combination of predictors in modeling crop yield for diverse climatic regions. Therefore, we proposed six crop yield linear models for each of the climatic divisions, and these models are then compared with support vector machine (SVM) models. All models showed reliable predictability based on adjusted R-square, normalized root mean square error (NRMSE), normalized mean prediction error (NMPE) parameters, and a p-value of less than 0.001.The impact of the independent predictor in the best crop yield models is discussed based on the regression weights (beta weight: β), and, the VGMmax is identified as the significant predictor in crop yield modeling for different climatic regions. Overall, this study will help the national agricultural management system for better monitoring and forecasting of soybean yield to support and manage soybean production., (© 2023.

- Abstract
Background: The ready-made garment (RMG) sector is a significant contributor to the economic growth of Bangladesh, accounting for 10% of the country's GDP and more than 80% of its foreign exchange earnings. The workforce in this sector is predominantly made up of women, with 2.5 million women working in the industry. However, these women face numerous challenges in carrying out their culturally-expected household responsibilities, including childcare, due to severe resource constraints. As a result, the children of these working women have a higher incidence of malnutrition, particularly stunted growth. This study aims to identify the factors that contribute to stunting in children under the age of five whose mothers work in the RMG sector in Bangladesh., Methods: The study collected data from 267 female RMG workers in the Gazipur district of Bangladesh using a simple random sampling technique. Chi-square tests were used to determine the associations between the factors influencing child stunting, and Multinomial Logit Models were used to estimate the prevalence of these factors., Results: The study found that the prevalence of moderate and severe stunting among the children of RMG workers living in the Gazipur RMG hub was 19% and 20%, respectively. The study identified several significant predictors of child stunting, including the mother's education level, nutritional knowledge, control over resources, receipt of antenatal care, household size, sanitation facilities, and childbirth weight. The study found that improving the mother's education level, increasing household size, and receiving antenatal care during pregnancy were important factors in reducing the likelihood of child stunting. For example, if a mother's education level increased from no education to primary or secondary level, the child would be 0.211 (0.071-0.627) and 0.384 (0.138-1.065) times more likely to have a normal weight and height, respectively, than to be moderately stunted., Conclusion: The study highlights the challenges faced by working women in the RMG sector, who often receive minimal wages and have limited access to antenatal care services. To address these challenges, the study recommends policies that support antenatal care for working-class mothers, provide daycare facilities for their children, and implement a comprehensive social safety net program that targets child nutrition. Improving the socioeconomic status of mothers is also critical to reducing child malnutrition in this population., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Haque et al.

- Abstract
Unplanned industrialization and improper management of wastes and gases into open surfaces are affecting the agricultural lands causing heavy metal pollution. This study monitored a suburban industrial zone located beside the Dhaka Export Processing Zone (DEPZ) at the Dhaka district in Bangladesh. We studied the heavy metal (Fe, Mn, Cr, Cu, Ni, Co, Zn, Pb, and Cd) concentration in the agricultural soils, plants, and in the atmospheric particulate matter (PM). The soils were found moderately contaminated with Fe, Cu, Ni, Co, and Zn and less contamination with Mn, Cr, Pb, and Cd. The enrichment factor (EF) and pollution load index (PLI) concluded a moderate level of soil pollution in this region. Besides, the plant samples showed an excess level of Cr and a similar level of Cu, Ni, Co, Zn, Pb, and Cd compared with the levels of industrial polluted sites of Bangladesh. The atmospheric PM analysis showed the presence of Fe, Mn, Cu, Ni, Zn, and Pb metals. The EF showed the anthropogenic origin of Mn and Ni in the atmospheric PM. The statistical correlation (r < 0.0001) of soil and plant heavy metals showed the possibility of transfer of metals from soil to plant which will cause the increase of pollution intensity. Overall, this agricultural region became an intermediate pollution zone. This study will help the decision-maker become conscious of heavy metal pollution in the suburban regions to monitor agricultural lands from anthropogenic pollution.
