Use of Solar Power for Agriculture
The power crisis in the path of civilization is undeniable today. Natural energy resources are being depleted, so effective development is not possible without the use of renewable energy. Renewable energy includes solar, wind, hydropower, biogas, etc. Despite the abundance of sunlight in the country, the use of solar energy in our country is not very promising as it is subject to the cost of night power generation by conserving solar energy. Although it has been promising to operate solar pumps during the day through direct use of solar energy, it has not gained much popularity due to wastage of agricultural land for installation of solar panels. Considering all these aspects, RDA has been able to bring 16-20 acres (about 50-60 bighas) of land under irrigation facility without wasting land through development of two-storied agriculture with solar power irrigation model. The project will also provide access to water extracted from solar pumps for irrigation as well as for food and household purposes and the water will be used for various productive purposes. Through the expansion of this technology, it will be able to play a helpful role in saving electricity used for irrigation and other purposes. Reducing the growing power demand of the country and expanding solar dependent irrigation facilities and two-tier agricultural technology in remote areas is very important in the current state of the country.
Solar-powered irrigation technology and Bangladesh
Bangladesh’s growing population, unprofitable paddy cultivation, over-use of water in paddy cultivation (about 3-4 tons of water per kg of paddy production) and declining cultivable land, in the light of these conflicting realities, threaten to ensure food security. In addition, the abundance of sunlight is a great blessing for the country, which can be identified as auxiliary energy, such as the conversion of solar energy into electricity (irrigation pump operation, electrification in remote areas, etc.) to reduce the increasing electrical pressure on the national grid. To make paddy cultivation profitable by using solar energy for irrigation, the density of the crop needs to be multiplied. To this end, agronomy and astronomy, ie the combination of agriculture and horticulture, through the effective use of sunlight, solar-powered irrigation technology, bed drainage system, including two-tiered agricultural technology can be introduced to achieve food security as well as profitable paddy cultivation quickly to profitable. Note that the current crop density in Bangladesh is 161%. Using two-tier agricultural technology model, it is very easy to increase the density two to three times. In addition, as a result of bed cultivation, it is possible to increase the production by additional 11% -14% with the saving of production materials. As a far-reaching effect, this model invented by RDA will play an effective role in alleviating poverty and improving the living standards of farmers.
Two-tier agricultural technology
Two-tiered agricultural technology is the process of growing two different crops of different heights on the same land at the same time. Mr. Md. Zafar Sadeq, an agriculturist who introduced the concept of the technology. On this innovation, Palli Unnayan Academy, Bogra adopted it as a sustainable technology by conducting field level research for the last few years and later re-applied the research on this technology. Innovates solar-powered two-tier agricultural technology model by ensuring irrigation facilities by installing solar panels through. Considering the success of the technology, the Rural Development Academy, Bogra has officially taken the initiative to expand the technology at the farmer level by taking up the project.
