Respon Padi Gogo terhadap Pupuk Hayati di Lahan Kering Kabupaten Konawe Selatan, Sulawesi Tenggara

Abstract

Response of Upland Rice towards Biological Fertilizer on the Dry Land in South Konawe District, South East Sulawesi. As the productivity of upland rice is still low, it requires technology improvement such as high yield variety and biological fertilizer. The purpose of this research was to determine the adaptability of upland rice varieties combined with biological fertilizer application. The experiment was conducted in the dry land of South Konawe District, South East Sulawesi using a factorial randomized block design with four replications of two factors. The first factor was three upland rice varieties namely Inpago LIPI Go1, Inpago LIPI Go2 and local varieties Kolono; the second factor was the combination of inorganic fertilizers and biological fertilizers. The experiment was carried out from December 2013 to March 2014. The results showed that the highest productivity was achieved by Inpago LIPI Go2 (4.5 to 5.2 t/ha) combined with the fertilizer combination as follow; Biofertilizer; Biofertilizer + 25% of recommended inorganic fertilizer; and Biofertilizer + 50% of recommended inorganic fertilizer without loosing the yield
