Pertumbuhan dan Hasil Tanaman Bawang Putih pada Berbagai Penambahan Lama Penyinaran Lampu LED Putih
LED lights can be used to increase the length of garlic plants that require a day length of more than 12 hours because it can help the photosynthesis process as a substitute for sunlight. This study aimed to determine the effect of increasing the length of illumination using white LED lights 100-watt with an intensity of 9685±385 lux on the growth and yield of garlic. The experiment was carried out from May to September 2021 in Balitsa Lembang, West Java. The experimental design was a split block design. The first factor is the addition of illumination length, namely 3 hours, 5 hours, 7 hours, and control. The second factor was variety, namely Lumbu Hijau and Tawangmangu Baru. The results showed that the addition of 5 hours of illumination to the Tawangmangu Baru was able to increase plant height, plant crown weight, and clove width. The addition of 3, 5, and 7 hours of illumination had no significant effect on plant height, the number of leaves, stem diameter, SPAD index, leaf area, specific leaf area, biomass, tuber weight, tuber diameter, and clove size of Lumbu Hijau.
