Biofertilizer: Azolla pinnata in-combination with Inorganic Fertilizer on Growth and Yield of Rice
Abstract A study was conducted at MARDI Seberang Perai, Penang. This study aims to examine Azolla pinnata on the growth and performance of the MR 297 variety. The experiment consisted of five treatments; PK + Azolla (T1); NP + Azolla (T2); NK + Azolla (T3); NPK-Control (T4), and Azolla only (T5). Each treatment has four replications. The experimental design used was a complete randomized block design (RCBD), and all data collected were analyzed using one-way ANOVA with a statistically significant 0.05% test. For the average soil analysis between the beginning and end, all soil analyses showed decreased soil properties except Total N (%) and organic carbon (%). Treatment has a significant influence on the tiller number, the number of panicles, and the yield per pot. There is a significant influence on treatment on plant height and SPAD value in crop growth performance. There was no significant effect on N and P in plant nutrients. In contrast, there was a significant treatment effect on K. This study showed that Azolla could be used as an alternative fertilizer on rice fields because the soil treated with NK + Azolla shows a comparable result with soil treated with inorganic fertilizer without Azolla on the total yield.
