Abstract

Peat soil has nutrient availability which is relatively low and soil acidity which is high and therefore contributes to the growth of hybrid pepper (Capsicum annuum). One of the efforts to improve the growth of hybrid pepper is by using Vesicles Arbuscular Mycorrhizal fungus (VAM) Gigaspora margarita and rice straw bokashi as organic fertilizer. This study aims to determine the growth of hybrid pepper plants on peat soil which is inoculated with VAM fungi and rice straw bokashi. This research had been done from August to November 2013.  The findings of MVA inoculated fungi did not significantly affect on the plant height and number of leaves but significantly affect on wet weight, dry weight and the percentage of root infection. The treatment of rice straw bokashi did not significantly affect the plant height, the numbers of leaves and the wet weight but significanty affect on the dry weight and percentage of root infection. The interaction between VAM and rice straw bokashi had no significant effects on all the parameters observed. The concentrations of VAM fungal inoculation VAM and the treatment of rice straw bokashi showed that the highest influence on each parameter is 15 g and 600 g respectively.

Abstract

The chlorophyll and lipid content in N. oculata can be influenced by the concentration of the culture medium. One of the substances, which has the potential to be an alternative culture medium, is rubber liquid waste. The purpose of this research was to understand the rubber liquid waste influence and its level of concentration as the alternative culture medium for N. oculata in terms of the chlorophyll and lipid content. The research was an experimental study with  completely random design with six treatments are the control (sea water), the concentration 10%,20%,30%,40% and 50% of rubber waste liquid. The chlorophyll content was measured by using spectrophotometer method, while the lipid content was measured by using Bligh and Dyer method. The ANOVA results of chlorophyll a and lipid content were showed a significant effect on the content of N. oculata chlophyll (F5,12 = 9,194; p < 0,05) and lipid (F5,12 = 23,818; p < 0,05). The result of the experiment demonstrated that the highest amount of chlorophyll and lipid was produced by the 10% concentration, 37.71 µg/ml and 3.77 g/200 ml respectively. Furthermore, the 50% concentration produced the lowest amount of chlorophyll and lipid, 2.37 µg/ml and 0.82 g/200 ml respectively.
