Abstract
The need for organic fertilizers is getting higher along with public awareness of the important role of organic fertilizers in increasing crop productivity including rice which is a food commodity that is preferred by the Indonesian population. In addition, the availability of inorganic fertilizers is increasingly limited so other alternatives are needed to use organic fertilizers intensively. This study aims to determine the effect of the application and non-application of organic fertilizers in increasing the biomass of Inpari 37 rice. The type of organic fertilizer used is in solid form (powder) with a land area of 20 acres which is located in the Experimental Garden of the Agricultural Technology Research and Assessment Installation (IP2TP). The cropping pattern uses legowo 6:1. This research is quantitative by describing each observation of Inpari 37 rice biomass and comparing the application with 3 repetitions and non-organic fertilizer application consisting of 3 repetitions with random sampling. Observations were made once a week at 08.00 WITA starting from the vegetative period (one week after transplanting) to the generative period (one week after harvest). The data processing uses ANOVA whose results are displayed in the form of tables and diagrams. The results for the highest rice plant height were found in the non-application U3 with an average length of 115.6 cm, the highest number of rice leaves was found in the non-application U2 with an average of 173 leaves, the green color of the rice leaves was good in the application and non-application average - the average in each replicate is green, the longest root length for non-application is in U3, which is 41.55 cm, the highest number of panicles in non-application U3 is 32 panicles, and the highest number of grains for non-application U3 is 3872 grains. This shows that the application of organic fertilizers to rice is not directly utilized by the soil so the impact or results of the application of organic fertilizers take a long time when compared to non-organic or chemical fertilizers which are directly absorbed by the soil. Therefore, in the application of organic fertilizers, it is necessary to apply non-organic fertilizers at the right dosage so that the nutrients can be more easily used by the soil in increasing the biomass of rice plants.
