Treating coffee grounds and its application as substrates for water spinach (Ipomoea aquatic) growth in hydroponic system
Main Article Content
Abstract
The study aims to identify a suitable treatment method of coffee grounds to make substrates for water spinach growth in the hydroponic system. The experiment was conducted completely random with 4 treatments of coffee grounds, respectivelywith (1) water, (2) lime, (3) vinegar, and (4) compost. The results showed that water spinach growth and yield on coffee grounds treated with lime was the highest. The obtained leaf and stem weight, fresh plant weight, root length, plant length, and leaf number of water spinach were 5.75 g, 7.21 g, 22.23 cm, 12.3 cm, and 7.45 leaves, respectively.
