Abstract

The objective of the study was to find out the respons of A. andraeanum and A. wave of love   to various fertilizer formula. The experiment was carried out on April 2007 to April 2008 in the plastic house in Segoro gunung, Karang anyar.  The experiment was arranged in a factorial design, with three replications.  The first factor was species of Anthuriums (A. andraeanum and   A. Wave of love), and the second factor was fertilizer formula.  The fertilizer used were granule slow release fertilizer (chemical fertilizer), green brown liquid fertilizer (organic), light green crystallic fertilizer (chemical), and green liquid fertilizer (organic). Plant height and number of leaves were measured at 6, 8, 10, and 12 months after planting, and flower number, flower stalk length, spathe length, spathe width, and spadix length were measured at 12 month after planting.  The results of the experiment showed that A. andraeanum dan A. Wave of love had different response to the fertilizer formula. Light green crystallic fertilizer, slow release fertilizer, and liquid green brown fertilizer were suitable for the vegetative growth of A. andraeanum, while only light green crystallic fertilizer and slow release fertilizer were proper to the vegetative growth of          A. Wave of love.  The generative growth of A. andraeanum was better in the application of light green crystallic fertilizer, and slow release fertilizer.

Abstract

High content of aluminium and low P availability in Inceptisols are the important limiting factors for crop production. Hence, important efforts on management of Inceptisols are the increasing in  P availability for crop demand. Cacao fruit skin bokashi is a source of organic matter used to improve the soil, although using bokashi  as organic fertilizer is still not yet have full attention.   A study that was aimed to elucidate roles of cacao fruit skin boakshi on Al concentration, and soil    P status in an Inceptisols was conducted in a laboratorium. Five treatments consisting of the rates of the bokashi (10, 20, 30, 40 and 50 ton/ha) and one control (no bokashi added) were arranged in a completely randomized design with three replicates. Results of the experiment showed that the application of 30 t ha-1 cacao fruit skin bokashi significantly increased soil pH, soil organic-C,                  P-total and P availability, and reduced Alexch concentration. However, the soil pH and P availability were reduced at the rate of bokashi of 40 and 50 t ha-1, but Alexch concentration was increased.

Abstract

The purpose of the study was to select several Trichoderma sp based on its sporalation capabilities, and antagonistic character, and effectiveness to control P. palmivora on cocoa pod.  The study consisted of two stages. In the first stage, a Completely Randomised design was used which consisted of seven treatments with three replicates: T. viridae, collection of  Laboratory of Plant Pest and Diseases of Bogor Institute of Agriculture (T-A), T harzianum, collection of Laboratory of Plant Pest and Diseases of Bogor Institute of Agriculture (T-B), T harzianum,  collection of  Coffee and Cacao Research centre of Jember (T-C), T koningii, collection of  Coffee and Cacao Research Centre of Jember (T-D), T. Trichoderma sp 1, collection of Laboratory of Microbiology  Life Sciences Centre of Bandung Institute of Technology    (T-E), Trichoderma sp 2, collection of Laboratory of Microbiology  Life Sciences Centre of Bandung Institute of Technology (T-F) and Trichoderma sp, collection of Laboratory of Plant Pest and Diseases University of Tadulako (T-G). Parameters measured were sporulation capability of Trichoderma sp, percentage of antagonisticity of Trichoderma sp towards in vitro P. palmivora . The second stage of the study was to determine the effectiveness of Trichoderma antagonisticity, either individual or mixed cultures in controlling the development of  P. palmivora on cocoa pod. The study was designed with seven treatments with three replicates:  T-D, T-E, T-G, T-DE  (mixed culture of T-D and T-E),  T-DG  (mixed culture of T-D and T-G), T-EG ( mixed culture of T-E and T-G), T-DEG (mixed culture of  T-D, T-E, and T-G). The results of the study showed that at in vitro condition the kinds of Trichoderma sp which had the highest antagonisticity on P. palmivora were  Trichoderma sp (T-G, T-E and T-D). They were effective to control P. palmivora on cocoo pod either in individual or mixed cultures.  However, T-G will be further developed due to its highest effectiveness as a biological control compared to the others.
