Daftar Isi:
- Massive breeding is often the case with the availability of the amount of water that can be stored on the media. The aim of this research is to know the influence of media and frequency of watering to the growth of cacao seedlings and to find the best media and optimum watering frequency. This experiment was conducted at Agricultural Faculty of Agriculture, University of Sumatera Utara, Medan (32 m asl) from Juneuntil September 2017. The researchal method used was Factorial Randomized Block Design with two treatment factors. The first factor is growing media with four type, M0 (topsoil) , M1 (topsoil: sand 2: 1), M2 (topsoil: rice husk 2: 1), and M3 (topsoil: rice husks charcoal 2: 1) and watering frequency: watered 1 (one) a day, watered every 4 (four) days , watered every 7 (seven) days, watered every10 (ten) days. The observed parameters were plant height, number of leaves, stem diameter, total leaf area, fresh shot weight, fresh root weight, shoot dry weight, dry root weight and root shoot ratio.The results showed that planting media treatment had significantly effect to plant height, number of leaves, fresh root weight, shoot dry weight and root dry weight. The best planting media treatment was found on topsoil (M0). Treatment of watering frequency did not significantly affect all observed variables. The interaction between the two treatments had a significantly effect on fresh root weight. Keywords: growing media, frequency of watering, cocoa.
