Peningkatan Produktivitas Padi Gogo (Oryza Sativa Linnaeus) Akibat Aplikasi Pupuk Urea Dan Bakteri Pemfiksasi Nitrogen Dalam Bahan Pembawa Pada Inceptisols Asal Jatinangor

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, order to fulfill continuous increase, researches were conducted land productivity. The of growth and productivity upland application Azospirillum sp. Azotobacter compost, Azolla, bran carrier studied. Nitrogen fixer applied as biofertiliser mean supply available nitrogen for This research was Ciparanje Experimental Field Soil Biology Laboratory, Faculty Agriculture, Universitas Padjadjaran. In this research, Randomized Block Design used analyze two factors: urea dose (100% 50%) Nfixer bacteria various carriers (individual combination liquid inoculant, green Azolla bran). result showed an interaction between factors towards grain weight rice. 100% higher compared 50% on weight. N combined gave highest number tillers, chlorophyll content,
