The Influence Of The Use Of Organic Fertilizers On The Yield Of Mentik Wangi Rice in Rice Fields Using the BUSISRI Method

Abstract

Rice is a food crop that produces staple food for the majority of the Indonesian population, one of which is in Klaten Regency. Almost all areas in Klaten Regency are planted with rice so that it becomes a food barn. However, this did not last long because the population growth rate and demand for black rice during the Covid-19 pandemic increased. In meeting the demand for white rice, especially fragrant mentik, there are still many obstacles, one of the obstacles is the land in Klaten Regency. The high cost of fertilizer, the level of consumer preference for consuming organic rice and the use of organic materials that are often found in society. To overcome this, the BUSISRI system cultivation (Unisri System Cultivation) is carried out using a method using liquid organic fertilizer. The aim of this research is to determine the effect of applying liquid organic fertilizer on mentik rice yields.The research was carried out from March to September 2023 in Dukuh Macanan, Jogosetran Village, Jogosetran Village, Kali Kotes District, Klaten Regency. This research is a type of single factor research with a Complete Randomized Block Design consisting of a single factor and will use 6 treatments and 4 replications. Data were analyzed using the F test at 5% level to determine the effect of treatment on variables. Observations continued with a DMR test at 5% level To compare the average between treatment combinations, the results of treatment with inorganic fertilizer (P1) were obtained for the highest plant height parameter, namely with an average of 58.20 cm. Treatment with inorganic fertilizer (P1) showed that the number of clump seedlings was greater, namely with an average of 13.30 stems, the inorganic fertilizer treatment (P1) showed the highest number of productive panicles with an average of 11.1 panicles, and showed a very significant difference from the treatment using Organic POC UREA (P5) and without treatment (P0) .
