The demand for water pumping in urban water supply and irrigation in Bangladesh is significantly influenced by electricity deficits and high diesel costs. To address these challenges, the adoption of solar power for water pumping emerges as a viable alternative to traditional systems reliant on grid power and diesel. In recent years, there has been a growing emphasis on clean and renewable energies, aligning with the environmental and economic priorities of Bangladesh. The agricultural sector, serving as the backbone of the country’s economy, witnesses an escalating demand for water as the population increases. The extraction and transfer of water for agricultural and drinking purposes translate to high-energy consumption. Leveraging the abundant and essentially free solar energy, particularly during the crop growth periods when irrigation is crucial, presents an optimal solution. This study underscores the underutilization of this vital resource in Bangladesh and advocates for the widespread implementation of solar energy conversion programs, specifically in photovoltaic pumping systems. By comparing these systems with conventional diesel pumps, this paper aims to inspire policymakers, statesmen, and industry professionals to integrate green energy into the water sector. The envisioned outcome is a strategic shift towards sustainable development, with a focus on harnessing solar power to pump water for villages and agriculture, thus contributing to economic and environmental sustainability.

An experiment in factorial format based on randomized complete block design with 3 replications was conducted to study the effects of zinc spray (0 and 1 g/L) and nitrogen fertilizer (0, 25, 50 and 75 kg/ha pure nitrogen) on yield and yield components of Phaseolus vulgaris. In maturity time, seed yield, 100 seed weight, number of pods per plant, number of seeds per pod and plant height were measured. Results showed that, use of zinc spray had a significant effect in 1% probability level on all measured traits. Also, the effect of nitrogen on all studied traits was significant in 1% probability level. Interaction effect of zinc spray and nitrogen fertilizer on number of seed per pod in 1% and on seed yield and plant height in 5% was significant and on other traits was non significant. The highest seed yield was obtained by zinc spray application with 1996 kg/ha. Among nitrogen fertilizer levels, use of 90 kg/ha pure nitrogen showed highest seed yield.
