Abstract
This experiment aimed to study the effect of Azolla pinnata in combination with chemical fertilizers on Riceberry growth and to assess the potential of Azolla pinnata in combination with chemical fertilizers to the yield of Riceberry. The experiment was designed in a Completely Randomized Design (CRD) with 3 replications. Five treatments were evaluated including T1 = non-fertilized (Control), T2 = chemical fertilizers (46-0-0, 16-20-0), T3 = Azolla pinnata 100 %, T4 = Azolla pinnata 50 % x chemical fertilizers (46-0-0, 16-20-0), T5 = Azolla pinnata 100 % x chemical fertilizers (46-0-0, 16-20-0). Growth and yield data were collected consisting of stem tillering, plant height, grain yield, percentage of filled and un-filled grain, and 1,000 grains weight. All Data were analyzed by analysis of variance (ANOVA) and compared between treatment means by using the Least Significant Difference (LSD) method. The results showed that the Azolla pinnata 100 % x chemical fertilizers showed the highest tiller number and plant height in the first 3 weeks after transplant. The Riceberry with Azolla pinnata 100 % x chemical fertilizers produces e highest grain yield. Percentage of filled grain the chemical fertilizers treatment gave the highest percentage of un-filled grain found in Azolla pinnata 50 % x chemical fertilizers the most, but 1,000 grains weight was not significant
