Abstract

Phosphorus (P) is a nutrient required by plants for saving and transferring energy as well as a component of proteins and nucleic acids. The existence of phosphate in the soil acidic abundant may not be able be used by the plant if the phosphate is in the form is not available. This research aimed to 1). Find out potential phosphate solubilizing bacteria and fungi derived from acid sulphate soil and red-yellow podzolic soil in increasing the amount of avaibility of phosphate to the acid sulphate soil, 2) find out the difference between giving phosphate solubilizing bacteria and fungi derived from acid sulphate soils and soil podsolic yellow red in increasing the amount of phosphate available on acid sulphate soil.This study uses a completely randomized design consisting of two factors, ie phosphate solubilizing microorganism and potency test media. The results showed that first selected fungus (fungus isolates from natural rubber plantations on acid sulphate soils) suppose to beRhizopus sp were able to increase the available phosphate highest at 12,11 ppm compared to control on non-sterile media and at 20,68ppmof control on soils sterile media. Provision fungal isolates treatment derived from acid sulphate soils and red yellow podzolic soil significantly in increasing the available phosphate on acid soils non-sterile when compared to provision bacteria

Abstract

This study aims to determine the effect of time and dose compost composting cow rumen contents on growth and yield of cauliflower (Brassica olerasea L.) on peat soil. Research using a completely randomized design (CRD) factorial with two factors. The first factor is the composting time (W) consisting of 3 levels: 15 days, 30 days and 45 days. The second factor is the dose composted cow rumen contents (D), which consists of four levels: 100 g.polybag-1, 200 g.polybag-1, 300 g.polybag-1and 400 g.polybag-1, repeated 4 times to obtain 48 units of trial. The results showed that there was no interaction effect between time composting and compost dose cow rumen contents on the growth and yield of cauliflower in the peat soil. Time composting 30 days is the best time because it can produce stover heaviest weight, ie 335.17 g.plant-1. Composting cow rumen contents at a dose of 400 g.plant-1 is the best because it produces a heavy dose of flowers, flower diameter and weight of the heaviest stover respectively 114.58 g.plant-1, 9.23 cm and 385.95 g.plant-1
