Abstract:
Rice is a stapple food consumed by most Indonesian people. Increasing the number of residents
encourages an increase in rice production, so land intensification needs to be done. Now, the
trend of a healthy lifestyle that is environmentally friendly encourages the creation of organic
farming. The effort of keeping the nutrient needs at the organic agriculture could be applied with
rice straw and Azolla utilization. This research was intended to find out the best dosage
combination of organic fertilizer and biofertilizer to total nitrogen, chlorophyll content, and yield
of rice. The experiment used randomized block design (RBD) which consisted of six treatments
and four repetitions, that was combination of organic fertilizer, Azolla, solid biofertilizer, and
liquid biofertilizer. The variabel observed was nitrogen content of soil, chlorophyll content, and
crop yields. The research result shows that application of rice straw compost 10 ton ha-1 with
liquid biofertilizer 5 L ha-1 can increase the rice yield up to 6.01 ton ha-1 , it was almost twice
compare with farmer practise which is use only rice straw compost. Addition of azolla 7.5 tons
ha-1 in the previous treatment did not increase rice yields and even obtained the same rice yield
but it was useful for maintaining soil quality and increasing rice yield next planting season. |
