Effect of Foliar Fertilizer and Irrigation Levels on Carrot Productivity
No full textCarrot (Daucus carota L.) productivity is still low in Tanzania due to inadequate management. There is dearth of information from the literature on the best management practices with respect to irrigation water (IW) and fertilizer levels for optimal carrot production. Consequently, farmers have limited access to means of boosting carrot productivity levels. Thus, a study was conducted to evaluate the effect of various levels of irrigation for carrots using drip irrigation and their interaction with carbonate foliar fertilizer (Lithovit standard) on the growth, yield, and sugar content of carrots at the School of Engineering and Technology (SoET) research field, Sokoine University of Agriculture (SUA) in Morogoro region, Tanzania. Crop water requirement (ETc) was calculated using established procedures upon which water application levels were based. Foliar fertilizer was applied at levels of 1 (F1), 1.5 (F2), and 2 (F3) g/L/plant, while irrigation levels applied were 60 (I1), 80 (I2), and 100 (I3) percent of ETc. The experiment was a 3x3 factorial with treatment combinations F1I1, F1I2, F1I3, F2I1, F2I2, F2I3, F3I1, F3I2, and F3I3 conducted over two seasons during 2020/2021 and 2021/2022. The highest yield of 30.9 t ha-1 of carrots was obtained under 100% ETc, and the lowest yield of 15.1 t ha-1 was obtained under the 60% ETc. Carrots under a deficit irrigation water level of 20%, i.e., 80% ETc were found to have the highest content of sugar. On the other hand, the highest yield of 26.1 t ha-1 of carrots was obtained under the 2 g/L/plant fertilizer level, and the lowest yield of 17.9 t ha-1 of carrots was obtained under the 1 g/L/plant fertilizer level. Carrots under the 1.5 g/L/plant fertilizer level were found to have the highest content of sugar. Therefore, for optimum growth and yield, full irrigation in combination with foliar fertilizer application at a level of 2 g/L/plant is recommended for carrots under Morogoro conditions. However, for high sugar content, irrigation at 80% ETc in combination with foliar fertilizer application at a level of 1.5 g/L/plant is recommended

Green Cooperatives and the Empowerment of Rural Women Entrepreneurs: Insights from Sunamganj, Bangladesh
No full textIn developing countries, agriculture plays a vital role in reducing poverty and enhancing food security. In Sunamganj, Bangladesh, rural women significantly contribute to agriculture but face gender disparities and limited access to resources. Green cooperatives provide a promising model to empower these women through sustainable practices and economic support. This study explores the roles and impacts of green cooperatives on rural women entrepreneurs in Sunamganj, focusing on factors influencing their involvement, the benefits, and constraints they face, and changes in empowerment before and after joining cooperatives. This study was conducted across five upazilas in Sunamganj, the sampled 200 women entrepreneurs-100 cooperative members and 100 non-members using purposive and snowball sampling techniques. Data was gathered via interviews, surveys, and focus group discussions (FGDs) and analyzed with SPSS and Microsoft Excel. Multiple regression analysis was used to identify key influencing factors and the Problems Confrontation Index (PCI) was utilized to assess the severity of challenges faced by members. The findings reveal that green cooperatives enhance women’s socio-economic status through improved production, market access, financial stability, and decision-making roles. Education, credit access, input availability, training, and experience were key drivers of the cooperative engagement of rural women entrepreneurs. However, challenges like male dominance, limited training, transportation issues, labor shortages, and market information gaps persist. Despite these, women in green cooperatives benefit from fixed pricing for organic products, increased bargaining power, and timely access to inputs and training. The study highlights the need for improved education, continuous training, extension services, high-quality inputs, and better infrastructure to support women’s participation further. The insights provided aim to guide policymakers in developing supportive policies that enhance the impact of green cooperatives, address gender-specific challenges, and promote the use of digital tools for market access. Future research should explore longitudinal studies and regional comparisons for deeper insights into rural women’s empowerment

No full textPigeon pea (Cajanus cajan L. Millsp.) is a vital grain legume known for its contribution to food security and soil fertility. However, pruning, which enhances plant architecture and yield, remains a significant challenge in its cultivation, especially in large-scale operations. Manual pruning is labor-intensive, time-consuming, and costly, which has led to the need for mechanized alternatives, a solar-operated pruner was developed at IGKV, Raipur, to reduce labour, time, and costs. This study focuses on the design, development, and performance evaluation of a solar-operated pruner tailored specifically for pigeon pea. The pruner integrates key components such as a cutting blade, DC motor, solar panel, battery, and charge controller. A 12 V DC motor, generating 10.53 N of force and operating at 8500 RPM, ensures efficient pruning. The motor is powered by a 7.2 Ah battery, which can be charged in 4 hours using an AC adaptor or 8 hours via a 10 W solar panel. The battery allows for 4-6 hours of continuous operation. The pruner\u27s lightweight PVC frame makes it portable and user-friendly, while the protective blade guard ensures operator safety. Performance evaluation of the pruner indicated a field efficiency of 81% and pruning efficiency of 76%. The actual field capacity was measured at 0.097 ha/h, with a walking speed of 1.2 km/h. Losses due to half-cut stems were calculated at 9.04%. The pruner demonstrated its ability to reduce labor costs, improve pruning efficiency, and promote sustainable agriculture through its solar-powered operation. This study highlights the economic and environmental benefits of adopting solar-operated pruners for pigeon pea cultivation
