Influence of Light Intensity on The Growth and Yield of Blue Ternate (Clitoria Sp.)
The growth of a plant relies on a series of interactions involving the presence of sunlight. Photosynthesis enables plant metabolism processes to take place and provides the energy that fuels these processes. This research study aimed to evaluate the impact of varying light intensities on the seed germination, growth and productivity of blue ternate plants (Clitoria ternatea L.). This was conducted at the University of Southern Mindanao, Kabacan, Cotabato, Philippines from July 2019 to June 2020. This was carried out in Split Plot Design arranged in Randomized Complete Block Design with four replications. Factor A refers to the exposure of Clitoria to different light intensities (high – 18,000-45,000 lux; medium - 3,000-5,200 lux; low – 1,300-2,200 lux) and factor B refers to the methods of planting (directly planted in the field and potted in polyethylene bags). The production of Clitoria flowers was significantly influenced by the interaction of light intensity and planting method. Highest flower yield was recorded in plants grown in areas with high light intensity and were directly planted in the field. In terms of pod and seed production, higher light intensity resulted in higher yield; however, no significant difference was noted between direct field-planted and potted Clitoria plants. The study generally implies that capability of Clitoria plants to produce flowers and pods was significantly affected by light intensity, wherein exposure in higher light intensity resulted in more flowers, pods and seeds.
