Abstract
Thie research aims to determine the production of corn plants with the use of N (urea) and Azolla Pinata doses. The research was conducted in September 2018 - November 2018 in Antirogo Village, Sumbersari District, Jember Regency. The design used was factorial Randomized Block Design (RBD) 2. The first factor is immersion of Azolla Pinata (A) with 4 levels: Without Azolla pinata (A0), the application of Azolla pinata 5 tons / Ha (A1), application Azolla pinata 7 tons / Ha (A2), application Azolla pinata 9 tons / Ha (A3). The second factor is the application of a dose of Nitrogen (N) with 4 levels: without the application of Nitrogen 0 Kg / Ha (N0), application of urea fertilizer (46% N) 100 kg / Ha (N1), application of urea fertilizer (46% N) 200 kg / Ha (N2), application of urea fertilizer (46% N) 300 kg / Ha (N3). The data analysis used is ANOVA and further tested using 5% DMRT. The results of this study indicated that the Azolla pinata application had a significantly different effect on the parameters of plant height 42 HST, dry shell weight per sample and was significantly different in the parameters of 100 seeds dry weight. Whereas the application of N (urea) has a very significant different effect on plant height observations of 28 HST, 42 HST plant height, dry cob weight per sample, cob length per sample, dry shell weight per sample plot, dry sample weight, and 100 dry weight seed. The interaction between the Azolla pinata application and the application of N (urea) differed not significantly in all observational parameters.
