Effect of different lights used on green amaranthus growth

Effect of different lights used on green amaranthus growth / Nurul Izzati Abdul Aziz
Permintaan sayur-sayuran di Malaysia semakin meningkat. Walaubagaimanapun, tanah di Malaysia tidak mencukupi untuk menanam sayur-sayuran selain harga upah dan racun serangga yang juga turut meningkat. Menurut data oleh FAMA, penggunaan sayur-sayuran per kapita merekodkan peningkatan yang stabil dengan 1% setiap tahun antara tahun 2009 dan 2014. Oleh itu, salah satu cara yang boleh digunakan untuk menghasilkan lebih banyak sayur terutama bayam, adalah tanam menggunakan lampu. Lima lampu yang berbeza telah digunakan dalam penyelidikan ini bagi mengkaji kadar pertumbuhan bayam. Antara lampu yang digunakan ialah lampu putih, lampu merah, lampu biru, lampu kuning dan matahari sebagai pemboleh ubah malar. Jenama yang digunakan ialah Philip dengan kuasa 35 wat. Eksperimen ini terbahagi kepada dua fasa iaitu fasa percambahan dan fasa pertumbuhan. Selepas 15 hari menanam bayam, keputusan dicatat. Berdasarkan keputusan, lampu merah didapati sebagai lampu yang paling berkesan digunakan untuk pertumbuhan bayam di mana ia menunjukkan kadar pertumbuhan yang paling tinggi. Selain itu, pH 5.6012 adalah lebih efektif berbanding 7.0 dan 8.0123. Hal ini demikian kerana boleh dilihat apabila semua aspek yang telah dikaji menunjukkan keputusan yang paling tinggi untuk pH 5.6012. _______________________________________________________________________________________________________ The demand for vegetables in Malaysia is increasing. However, Malaysia does not have enough land to plant crops besides the price labor and pesticides also increasing. According to the data by FAMA, per capita consumption for vegetables recorded a steady increase of about 1% each year between 2009 and 2014. Therefore, one of the ways that can be used to produce more vegetables especially spinach, is by growing them using lights. Five different lights were used in this research to study the growth rate of green amaranth. The lights are white light, red light, blue light, yellow light and sunlight as a control variable. The model used is Philip with 35 watt each. The experiment is divided in to stage, germination stage and growing stage. After 15 days of planting the green amaranth or spinach, the results were obtained. Based on the results, red light is the most effective light for the growth of green amaranth as it shows red light has the highest growth rate. Besides, pH of 5.6012 is more effective compared to 7.0 and 8.0123. This can be seen when all aspects that were being studied show highest result for pH 5.6012.
