Abstract

Agricultural waste can be fermented into liquid organic fertilizer to provide nutrition and phytohormon for plants. The application of this liquid organic fertilizer will improve nutrient availability, the root morphology, growth and yield of plants. The objective of this research was to examine the effect of NPK synthetic fertilizers and different types of Liquid Organic Fertilizer (LOF) on plant growth and rice yield. The experiment was conducted at Bener Village, Ngrampal sub-district, Sragen district, Indonesia, from March until November 2011. The experiment was developed according to Randomized Completely Block Design with five replicates. The treatments were: LOF “Double”, LOF “Plus”, LOF “Bacteria”, LOF “Bacteria+Plus”, and NPK fertilizers (Control without LOF). Plant growth was measured weekly on five plant samples and plant yield was assessed at harvest time. The data was subjected to an analysis of variance followed by Duncan’s Multiple Range Test. The results showed that plants treated with synthetic fertilizer (NPK, Control) have the lowest plant growth and rice yield compared to those treated with LOF. The types of fertilizer applied did not affect the number of tillers. Plants treated with LOF “Bacteria+Plus” or LOF "Plus" displayed more leaves and better plant height of than those treated with LOF “Double” or synthetic fertilizer. Plants treated with LOF “Bacteria+Plus” or LOF "Plus" had a significantly higher number of seed/panicles, grain weight per hill, per plot and per hectare than those treated with LOF “Double” or synthetic fertilizer. KEY WORDS: Biological agents, agricultural waste, liquid organic fertilizer, rice
