Abstract
Komoditas padi menjadi komoditas pangan utama dengan konsumsi pangan masyarakat yang cukup besar. Produksi padi dalam kurun waktu 3 tahun terakhir mengalami fluktuasi yang diiringi dengan penurunan luasan panen. Penurunan produksi padi dapat mempengaruhi pemenuhan konsumsi beras nasional. Selain itu, Jawa Timur diketahui sebagai salah satu wilayah dengan potensi penghasil padi yang tinggi namun penurunan luas panen juga terjadi sehingga produksi padi yang dihasilkan juga menurun. Peningkatan kesuburan tanah pada lahan sawah dapat dilakukan dengan pengintegrasian tanaman padi-ternak (ikan dan itik) maupun dengan tumbuhan penambat N (azolla), yang dikenal dengan sebutan Complex Rice System. Tingginya potensi aplikasi Complex Rice System dalam peningkatan produksi tanaman padi, sehingga perlu dilakukan penelitian lebih lanjut mengenai efektifitas pengaplikasian itik, azolla dan ikan dalam peningkatan ketersediaan hara terhadap peningkatan produksi tanaman padi. Penelitian ini dilaksanakan pada bulan Oktober 2021 hingga Juni 2022 yang berlokasi di Desa Sukorejo Kecamatan Gondanglegi, Kabupaten Malang, Jawa Timur. Tahapan penelitian yang dilakukan meliputi: persiapan lahan dan penanaman, pengambilan sampel tanah, aplikasi ikan, itik dan azolla, pemupukan (aplikasi pupuk kandang kambing dan aplikasi pupuk anorganik berupa pupuk NPK, urea dan ZA), pemeliharaan (penyulaman, penggenangan, penyiangan gulma), pengamatan parameter pertumbuhan, pengamatan parameter produksi, panen, analisa ketersediaan hara tanah (C-organik, N-total dan P-tersedia). Analisis sampel dilakukan di laboratorium Departemen Tanah Fakultas Pertanian Universitas Brawijaya. Penelitian dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) dengan 6 perlakuan dan 4 kali ulangan. Data dianalisis dengan sidik ragam dan diuji lanjut DMRT dengan taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa aplikasi Complex Rice System memberikan pengaruh nyata terhadap tinggi tanaman, jumlah anakan, jumlah daun dan berat basah tanaman. Perlakuan P2T1 (pupuk anorganik dan ikan) memberikan hasil tertinggi dengan nilai tinggi tanaman 108,7 cm, jumlah anakan 21,4 anakan, jumlah daun 64,2 helai dan berat basah tanaman 367,07 gram. Aplikasi Complex Rice System memberikan pengaruh nyata terhadap C-organik. Perlakuan P1T3 (pupuk organik dan azolla) memberikan hasil tertinggi dengan nilai C-organik 2,196%. Aplikasi Complex Rice System memberikan pengaruh nyata terhadap Ntotal. Perlakuan P2T2 (pupuk anorganik dan itik) memberikan hasil tertinggi dengan nilai N-total 0,254%. Aplikasi Complex Rice System memberikan pengaruh nyata terhadap jumlah anakan produktif. Perlakuan P2T3 (pupuk anorganik dan azolla) memberikan hasil tertinggi dengan nilai jumlah anakan produktif 19,1 anakan.
English Abstract
Rice is the main food commodity with a fairly large public food consumption. Rice production in the last 3 years has fluctuated accompanied by a decrease in harvested area. The decline in rice production can affect the fulfillment of national rice consumption. In addition, East Java is known as one of the areas with high riceproducing potential, but a decrease in harvested area has also occurred so that the production of rice produced also decreases. Increasing soil fertility in paddy fields can be done by integrating rice-livestock plants (fish and ducks) or with N-fixing plants (azolla), known as the Complex Rice System. The high potential for the application of Complex Rice Systems in increasing rice production, so it is necessary to do further research on the effectiveness of the application of ducks, azolla and fish in increasing nutrient availability to increase rice production. This research was conducted from October 2021 to June 2022, located in Sukorejo Village, Gondanglegi District, Malang Regency, East Java. The stages of the research include: land preparation and planting, soil sampling, application of fish, ducks and azolla, fertilization (application of goat manure and application of inorganic fertilizers in the form of NPK, urea and ZA fertilizers), maintenance (embroidering, flooding, weeding), observing growth parameters, observing production parameters, harvesting, analyzing the availability of soil nutrients (Corganic, N-total and P-available). Sample analysis was carried out in the laboratory of the Department of Soil, Faculty of Agriculture, Universitas Brawijaya. The study was conducted using a Randomized Block Design (RBD) with 6 treatments and 4 replications. Data were analyzed by means of variance and further tested by DMRT with a significance level of 5%. The results showed that the application of the Complex Rice System had a significant effect on plant height, number of tillers, number of leaves and fresh weight of plants. P2T1 treatment (inorganic fertilizer and fish) gave the highest yield with a plant height of 108.7 cm, number of tillers 21.4 tillers, number of leaves 64.2 leaves and plant fresh weight 367.07 gram. The application of the Complex Rice System has a marked effect on C-organic. The P1T3 treatment (organic fertilizer and azolla) gave the highest yield with an organic C value of 2.196%. The Complex Rice System application has a significant effect on N-total. The P2T2 treatment (inorganic fertilizer and ducks) gave the highest yield with a total N-value of 0.254%. The Complex Rice System application has a real influence on the number of productive tillers. The P2T3 treatment (inorganic fertilizer and azolla) gave the highest yield with a productive tiller value of 19.1 tillers.
