Pengaruh pencahayaan terhadap produktivitas green fodder gabah padi pada kepadatan benih yang berbeda

Abstract

The use of LED (light-emitting diode) lights in indoor hydrophonic systems can optimize the photosynthesis process in plants. This research aims to examine the use of different lighting to maximize green fodder productivity. The use of LED grow lights is expected to have an influence on the growth and productivity of animal feed. Different seed density treatments aim to analyze the level of seed density so that optimal results are obtained. Research activities include testing seed germination and forage production. Green fodder production activities were carried out using a 2x3 factorial completely random plan (RAL) with 3 replications. Consisting of 2 factors, factor A is the influence of lighting (L: LED grow light; M: Sun), and factor B is seed density (P1: 300 g/m2, P2: 500 g/m2, and P3: 700 g/m2). The research results showed that the use of LED grow lights can increase plant height and fresh biomass productivity. A seed density level of 700 g/m2 obtains the highest biomass production value. Seed conversion based on seed density P3 (3.61) is lower than P1 (3.84) and P2. (4.37), because there is only a slight difference in fresh biomass P2 and P3.
