Abstract

This experiment was conducted to study the effect of organic fertilizer and plant spacing on organic-C, soil fungi population, dried weight root and rice yield (Oryza sativa L.) grown on Inceptisols Jatinangor. This experiment was arranged in split plot design, consisted of two factors with 12 treatments and three replications. The first factor as main plot was organic fertilizer, which dosage of 0, 200, 400 and 600 kg ha-1 respectively. The second factor as sub plot was plant spacing, which of 25 cm x 25 cm , 30 cm x 30 cm and 35 cm x 35 cm, respectively. The result of experiment showed that there were no interaction effect between organic fertilizer and plant spacing on organic-C, soil fungi population, root dry weight and rice yields. The main effect of plant spacing treatment gave significantly effected on dried weight of root and rice yields per plot and per 10 stool. The highest rice yield per plot, 9.276 kg plot-1 (4.638 t ha-1)was achieved from plants with  spacing 25 cm x 25 cm and the highest rice yield per 10 stools was 747 g from plants with spacing.35 cm x 35 cm.
