| Summary: | The research had been done in Pereng, Mojogedang, Karanganyar. The aim of the research is to know the influence of enrichment of organic fertilizer with the addition of Silk Tree litter (Albizia falcataria L.) in improving the availability and Mg uptake of rice plants (Oryza sativa L.) fields in Alfisol. The research used a basic design factorial with two factors, it were dose and cropping systems. The data analysis used F test on level 5%, Kruskal-Wallis test, DMR test on level 5%, Mood Median test, and correlation test. The results of the research showed that the availability and uptake of Mg in conventional cultivation system is higher than the SRI cultivation system. Mg uptake in conventional cultivation systems of 0.015 g/plant. The highest Mg availability can be achieved in the combined treatment D6B1 (conventional and 50 % + 100% organic fertilizer dose recommendations Silk Tree litter + 15% weight of organic fertilizer) of 2.34 cmol(+)/kg. Organic fertilizer with the addition of Silk Tree litter can not enrich the availability and uptake of Mg, but conventional cultivation systems influence the availability and uptake of Mg. Conventional cultivation systems influence the availability and uptake of Mg is higher than the SRI cultivation system. |
