In the heart of Bangladesh, a revolution is brewing in the fields, and it’s not about the crops alone. It’s about how technology is transforming the way we grow them. Khokan Kumer Sarker, a researcher from the Irrigation and Water Management (IWM) Division at the Bangladesh Agricultural Research Institute (BARI), has led a groundbreaking study that could redefine summer tomato production in the region and beyond.
Imagine a world where farms are not just fields but smart ecosystems, where every drop of water is accounted for, and every plant gets exactly what it needs. This is not a distant dream but a reality that Sarker and his team are bringing to life. Their innovative IoT-enabled sensor-based automated shed and irrigation system is a game-changer for summer tomato production in Bangladesh.
Traditional methods of tomato cultivation in Bangladesh involve tunnel-fixed polyethene sheds or open fields with surface flooding irrigation. These methods often lead to excess water use and high temperatures, reducing crop productivity. But Sarker’s system is different. It’s a sophisticated blend of hardware, software, and field experiments designed to optimize crop growth.
The system consists of sensors that monitor rain, temperature, and light, triggering an automated shed to open or close as needed. An automatic drip irrigation system ensures that the plants get the right amount of water at the right time. “The automatic shed with a drip irrigation system reduces labor costs and maintains crop yield,” Sarker explains. This is not just about increasing yield; it’s about sustainability and efficiency.
The results speak for themselves. The IoT-enabled system produced 1.11 times more yield compared to traditional tunnel-fixed polyethene sheds and 1.67 times more than open field cultivation. The shed protected the crops from temperatures above 35°C, heavy rainfall, and intense sunlight, creating an optimal growing environment.
But the implications of this research go beyond just tomatoes. This technology can be adapted for other high-value crops, contributing to global food and water security. It’s a step towards smart agriculture, where technology and nature work hand in hand.
The energy sector, too, has a lot to gain from this. Precision agriculture reduces the need for excessive water and energy, making farming more sustainable. It’s a win-win situation for both farmers and the environment.
The study, published in the journal Results in Engineering, translates to “Results in Engineering” in English, is a testament to the power of innovation. It’s not just about growing tomatoes; it’s about growing a sustainable future. As climate change continues to pose challenges, such technologies will be crucial in ensuring food security and sustainable farming practices.
Sarker’s work is a beacon of hope, showing us that with the right technology and innovation, we can overcome even the toughest challenges. It’s a call to action for the agricultural sector to embrace technology and pave the way for a smarter, more sustainable future. The future of farming is here, and it’s smart, efficient, and sustainable.
