Abstract

This research was conducted at Experimental Farm, State Polytechnic of Jember, from June to August 2018. The purpose of this study was to determine the proper dose of N fertilizer on mustard plants with planting patterns of intercropping. The design used was a randomized block non factorial design of 5 treatments Urea fertilizer (100,75,50,25 and 0 kg / ha) and 4 replications. The size of the treatment plot is 2m x 10m. the spacing used is 20 x 20 cm. in the monoculture cropping pattern, the planting population density is 250 plants, while in intercropping plants is 200 plants. The results of the study showed that the highest yield results in 100 and 75 Urea kg/ha fertilization treatment, the ratio of land equality ratio (LER) was more than 1, so that land productivity increased by using intercropping patterns.
