PENGARUH MACAM DAN KONSENTRASI PUPUK ORGANIK CAIR DARI LIMBAH PERTANIAN TERHADAP PERTUMBUHAN DAN HASIL TANAMAN LOBAK MERAH (Raphanus sativus L.)

Abstract

Red radish (Raphanus sativus L.) is a type of vegetable with health benefits and potential for cultivation. The application of liquid organic fertilizer (LOF) can enhance plant growth and yield. This study aims to determine the effect of the type and concentration of liquid organic fertilizer from agricultural waste on the growth and yield of red radish. This research was conducted from July 12, 2024, to August 14, 2024 in Perum Joyogrand Kelurahan Merjosari, Malang, Jawa Timur The research used a Factorial Completely Randomized Design with two factors: the type of liquid organic fertilizer (rice straw mixed LOF and Paitan Plant LOF) and the concentration (0, 50, 100, 150, and 200 ml/L). Each treatment combination was repeated three times with three plants per treatment. The results showed a significant interaction between the type of liquid organic fertilizer and concentration on plant height, leaf number, fresh and dry weight of the plant, root weight, root diameter, and chlorophyll content. The best combination for the growth and yield of red radish was found in paitan plant LOF at a concentration of 200 ml/L (P₂K₄), which gave better results compared to other concentrations. Meanwhile, the rice straw mixed LOF showed optimum concentration at 100 ml/L. Based on these results, it can be concluded that the application of paitan plant LOF at a concentration of 200 ml/L has the best effect on the growth and yield of red radish, while for rice straw mixed LOF, the optimum concentration is 100 ml/L..
