Liquid Organic Fertilizer and Planting Space Influencing
the Growth and Yield of Rice (Oryza sativa L.) in System
of Rice Intensification (SRI) Methods
Abstract: This research aimed to know the influence of liquid organic fertilizer and planting space to the growth and yield of rice in
System of Rice Intensification (SRI) methods. The research was conducted in Palur, Sukoharjo, laid on 98 m above sea level from
December 2008 to April 2009. Experimental design used was Randomized Completely Block Design with two factors of treatment.
The first factor was liquid organic fertilizer; consist of control, cebreng leaf, rumen of goat, banana tree hump, and maja fruit. The
second factor was planting space; consisting of 25 cm × 25 cm, 30 cm × 30 cm and 35 cm × 35 cm. There were 15 combinations of
treatment and each repeated three times. Data analyzed with F test at 5% and DMRT at 5%. Research result showed that liquid organic
fertilizer of maja fruit serves the best on variable of stalk length. Planting space of 35 cm × 35 cm serves the best on variable of plant
height, number of total sapling, number of productive sapling, weight of dry plant, weight of rice per clump, and weight of 1,000 rice
grains. There is no interaction between liquid organic fertilizer and planting space on all variables
