The Improvement of Soil Chemical Properties of Typic Hapludults by Organic and Inorganic Fertilizers

Abstract

Polyanthestuberosa L. is a potential flowering plant that will be developed in Jatinangor. However, the Typic Hapludults soil in Jatinangor has a clay texture, an acid soil reaction, and a high level of total-P, but there is a low available-P, which will make tuberose growth difficult. The aim of this study was to obtain the potential composition of organic and inorganic fertilizers for tuberose growth on Typic Hapludults. We used organic and inorganic fertilizers with different compositions and dosage recommendations (0/0; 0/1; 1/0; 0.5/0.5; 0.5/1; 1/0.5; 1/1.5; 1.5/0; 1.5/0.5, and 1.5/1 for organic/inorganic fertilizers, respectively). The combination of organic and inorganic fertilizers had a positive effect on soil reaction (pH), available-P, total-P, and fresh weight of tuberose on Typic Hapludults. The application of 50% organic + 50% inorganic fertilizers was an effective combination in increasing plant growth by improving the fresh weight up to 9240 g plant-1 or increasing the fresh weight by 39% compared with control
