Morfofisiologi Akar Melalui Interval Penyiraman, Pemberian Mikoriza dan Modifikasi Media Tanam pada Pembibitan Kakao (Theobroma cacao L.)

Abstract

This objective of this was to deterrnine the watering interval, concentration of mycorrhizae, and the best growing media for cocoa seedlings. Experiments carried out in the kassa house Tobacco Deli and Cane Research Institute Medan, Province of North Sumatera, from July 2016 until October 2016. The design environment used in this study were Randomized Block Design with factorial pattern. The first factor was the watering interval with three levels of watering interval: once of every 1, 3, and 5 days. The second factor was the inoculation of mycorrhizae consisting of three levels: without inoculation of mycorrhizae, mycorrhizae inoculant 50 grlplant and 100 grlplant. The third factor was the growing media with four levels of growing media: soil, soil + fiber, soil + TKKS, and soil + sludge. Giving the watering interval once of every 3 days and application of mycorrhizae with 100 gr/plant concentration on growing media of soil + fiber is the best tneatment for growth of cocoa seedlings that is stem diameter and leaf number parameters
