Abstract

Kale memerlukan pencahayaan minimal 14-16 jam setiap hari untuk pertumbuhan yang optimal, sehingga cahaya dapat memengaruhi fase vegetatif dan kualitas keseluruhan tanaman kale. Tujuan penelitian ini adalah untuk mendapatkan spektrum cahaya dan lama penyinaran yang memberikan hasil optimal terhadap pertumbuhan dan hasil produksi dua varietas tanaman kale. Penelitian dilakukan di Greenhouse UG Technopark pada bulan April-Juni 2024 menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) Pola Tersarang (Nested Design) yang terdiri dari dua faktor yaitu faktor I (petak utama) adalah spektrum cahaya dan lama penyinaran (L) terdiri dari 10 taraf. Faktor II (anak Petak) yang tersarang pada spektrum cahaya dan lama penyinaran adalah jenis varietas kale (V) terdiri dari 2 taraf. Perlakuan diulang sebanyak 4 ulangan. Parameter yang diamati adalah tinggi tanaman (cm), lebar daun (cm), jumlah daun (helai), laju pertumbuhan tinggi tanaman (cm/hari), diameter batang (cm), bobot segar tanaman (g), dan bobot kering tanaman (g). Data yang diperoleh dianalisis menggunakan analisis sidik ragam (ANOVA) dan selanjutnya perlakuan yang pengaruhnya nyata akan dianalisis uji lanjut dengan uji Duncan’s Multiple Range Test (DMRT) pada taraf a = 5%. Hasil penelitian menunjukkan bahwa perlakuan spektrum cahaya dan lama penyinaran berpengaruh nyata terhadap tinggi tanaman, lebar daun, jumlah daun, bobot segar tanaman, dan bobot kering tanaman, sedangkan perbedaan varietas berpengaruh nyata terhadap tinggi tanaman, lebar daun, laju pertumbuhan tinggi tanaman, dan diameter batang.

Abstract

The high demand for water spinach demands increased production through more efficient cultivation techniques. One important factor that affects plant growth and production is lighting. This study aims to optimize the growth and production of two varieties of water spinach by adding LED lights with a certain light spectrum and duration. The study used a Nested Complete Randomized Block Design (RBD) consisting of two factors. The first factor is the light spectrum (L) with 3 levels, namely the red light spectrum of the 18/6 photoperiod (L1), the blue light spectrum of the 18/6 photoperiod (L2), and the red-blue light spectrum of the 18/6 photoperiod (L3). The second factor is the variety of water spinach (V) consisting of two levels, namely the curly water spinach variety (V1) and the lacinato water spinach variety (V2). Each treatment was repeated 4 times so that there were 24 experimental units. Data analysis used ANOVA with a 5% confidence level and further testing using the Duncan test. The results showed that the growth and production of the two varieties of water spinach were more optimal with the addition of the red-blue light spectrum.
