Abstract

The research had been done in Pereng, Mojogedang, Karanganyar. The aim of the research is to know the influence of organic fertilizer enrichment with the addition of Silk Tree litter (Albizia falcataria L.) to improve the availability and the uptake of Mg on the paddy (Oryza sativa L.) fields in Alfisol. The research used Complete Randomized Block Design (CRBD) with two factors that were dose treatments and cultivation systems. The data analysis used F test, Kruskal-Wallis test, DMRT test, Mood Median test, and correlation test at the 5% significance level. The results of the research showed that the availability and uptake of Mg in conventional cultivation system are higher than the SRI cultivation system. Mg uptake in conventional cultivation systems amount to 0.015 g/plant. The highest Mg availability can be achieved in the D6B1 treatment (50% organic fertilizer + 100% dose recommendation + Silk Tree litter amount 15% of the weight organic fertilizer) amount to 2.34 cmol(+)/kg. Organic fertilizer with the addition of Silk Tree litter cannot enrich the availability and uptake of Mg, but conventional cultivation systems can influence the availability and uptake of Mg. Conventional cultivation systems influencing the availability and uptake of Mg are higher than the SRI cultivation system.

Abstract

The aim of the research was to test the System of Rice Intensification (SRI) method in improving the biological properties of paddy soil. The indicators of improvement were measured by the number of earthworm feces (cast), and the population of some microbial and nutrient content in the cast. The experiments were performed by comparing the three methods, namely: (1) SRI, (2) semi-conventional, and (3) conventional, using Randomized Completely Block Design. Each treatment was repeated nine times. The experiments were performed in the paddy fields belonging to farmers in Sukoharjo, Central Java. The result showed that the SRI (application of 1 tons ha-1 of vermicompost + 50% of inorganic fertilizer dosage) tends to increase the number of earthworms cast. It is an indicator of earthworm activity in soil. Earthworms cast contains more phosphate solubilizing  bacteria (12.98 x 1010cfu) and N content (1.23%) compared to its surrounding soil. There is a close functional relation between earthworms cast with total tiller number. SRI method is better than the other two methods to improve the biological characteristics of paddy soil that has the potential to maintain the sustainability of soil productivity.
