White, blue and red LED lights lit in a cell of Sher-e-Bangla Agricultural Faculty. Under its various types of vegetables Under the roof, it is possible to get the same amount of vegetables as an alternative to sunlight using LED lights.
After the last three years of research, the information was given by the Department of Horticulture Department of Sher-e-Bangla Agricultural University, AFM Jamal Uddin. He said, there are seven rays in the sun's light. By using different colors of rays, the plant produces its food. As a result, crop production is possible in the absence of sunlight using different color lights. The proper combined use of light is necessary.
About the benefits of vegetable cultivation in LED light, Jamal Uddin said that the cultivation of vegetables in the open field is attacked by various types of insects. As a result, the quantity and quality of the crops are wasted. But due to the green-cultivated vegetables cultivated in LED light, disease is less. Management is very easy due to being in a controlled environment. Weeds are less.
The researcher said that the yield of tomato variety is different. However, under the study of LED lights, the varieties of tomato cultivated have been found to be similar to the cultivation of their produce. He said that barry 14 tomatoes were planted and 3 to 3 kg of tomatoes were found in the plant. Apart from this, chilli cultivation has yielded one to one and a half kg seedlings per plant in four months, which is similar to the field yield. He said that 2 kg of pigeonpea was found in the cultivation of brinjal.
The cost of cultivating LED lights is higher in the first place, but it is possible to cultivate almost 10 years at this cost. In addition, vertical method of vertical method (vertical aggregation) is possible in LED light. As a result, where there are cultivated one-layer, it is possible to cultivate in a few levels in vertical manner. This method is effective for the city.
In this method, vegetables are fitted with cocodust, sandy-loamy soil and earthworms. After that, the lighting was made to light the tree with light LED lights. Due to not being able to make extra temperatures, LED bulbs are very close to the trees but there is no problem.
Jamal Uddin said that initially only white LED lights have been found in the study, because the tree growth is good, but the yield is less. After adding white light to the blue color lights, it is seen that potato vegetables are growing well. But there was no yield in the herb of vegetables. Next year the red lights were given with white and blue lights. It increases the amount of fruit and fruit of tomatoes, brinjal, chilli and strawberry.
However, the researcher advised some areas to be careful in the field of LED light. For example, the timing of burning lights is to be kept in mind. In case of different crops, the time limit for keeping the plant light is different. In this case, it is best to fix the LED light through the timer (time control).
Jamal Uddin said about the future of cultivation under the roof under LED lighting, a large part of the necessary food is possible in this method.
