Effects of Using Multiple LED Beams on Red Dragon Fruit (Hylocereus polyrhizus). Red dragon fruit plant (H. polyrhizus) is a tropical plant and is very adaptable to growing environments and weather changes such as sunlight, wind, and rainfall. Dragon fruit plants is a long day plants (plants that require long enough sun exposure), which means that to produce this plant requires at least 12 hours of radiation. Knowing this, there needs to be a solution so that production stability can be controlled, one of which is by modifying the environment. The purpose of this study was to determine the effect of several colors of LED light (Light Emitting Diode) at the initiation stage of dragon fruit flowers in an effort to increase production. This study used a randomized block design with four treatments and nine replications, while the treatment consisted of control plants, the administration of white LED lights, yellow LED lights and blue LED lights. Three variables were observed, namely the number of flower buds, the number of blooming flowers and the number of young fruits. The results showed that the use of yellow LED lights give the best light intensity when compared to other treatments so that the yellow LED light treatment gave the best results on each variable including 6.44 pieces for flower buds, 7.56 pieces for flowers blooms and 7.56 pieces for young fruit.

Recently, light traps using light-emitting diode (LED) lights have been applied to monitor or control insect pests. The oriental armyworm, Mythimna separata Walker, is an important insect pest that has caused damage to several cereal crops, including corn, wheat and rice. The present study aims to seek out a sensitive wavelength causing high phototactic response in M. separata. The study evaluated the phototactic responses of M. separata moths to several LED lights of different wavelengths and luminance intensities under laboratory condition. Results showed that green (520 nm) LED light resulted in significant phototactic response of M. separata moths compared to LED lights of other wavelengths. Additionally, the highest attraction rate of the moths to green LED light appeared in luminance intensity group of 200 lux compared to the other intensities groups. Experiments under optimum conditions based on the above experiments revealed that the green LED light exhibited the strongest attraction rate (64.44%) among all experimental groups. An experiment performed in a net cage also showed that green LED light resulted in the highest phototactic response of M. separata moths, 1.7 times more than a commercial black light used as control. These findings clearly demonstrate that M. separata moths have a high sensitivity to the green LED light. Therefore, a light trap equipped with green LED light could be useful for monitoring and controlling M. separata moths.

This study aims to optimize the conditions for “Genovese” basil (Ocimum Basilicum) germination and growth in an indoor environment suitable for horticulture through a synergic effect of light and fertilizers addition. In fact, several studies determined that specific light conditions are capable of enhancing basil growth, but this effect is highly dependent on the environmental conditions. In this study, the effect of different light sources was determined employing a soil with a negligible amount of fertilizer, demonstrating substantial improvement when light-emitting diode (LED) lights (hyper red and deep blue in different combinations) were applied with respect to daylight (Plants height: +30%, Total fresh mass: +50%). Thereafter, a design of experiment approach has been implemented to calculate the specific combination of LED lights and fertilizer useful to optimize the basil growth. A controlled-release fertilizer based on nitrogen, phosphorus, and potassium (NPK) derived from agro-residues was compared with a soil enriched in macronutrients. The results demonstrate significant improvements for the growth parameters with the employment of the controlled-release NPK with respect to enriched soil combined with a ratio of hyper red and deep blue LED light equal to 1:3 (Total fresh mass: +100%, Leaves number: +20%).
