Multiple crops of corn and soil beans in “double row” expected can increase efficiency of urea fertilizing and efficiency of land . this research aims to (1) knowing the efficiency of the urea fertilizing in increasing the result of the corn in “double row” of multiple crop with soil beans and (2) for knowing efficiency land in increasing the result of the corn “double row” on the system of multiple crop with soil beans. This research was conducted in Laboratory Lapang Terpadu Agriculture Faculty University of Lampung and Laboratory Ilmu Tanam Agriculture Faculty University of Lampung on July until October 2014. The design used in this study is design of group randomized perfect with three replications and nine treatments. Diversity tested with Barlett test, the properties of the additive or the data additive were tested by the tukey test. The separation of the median value was tested by an orthogonal polynomial test with an opportunity of error determined at 5%. The results showed that intercropping of corn “double row”and peanuts did not affect the efficiency of urea fertilization agronomically. The results showed that intercropping of corn and peanuts were able to utilize land use. The value of land use efficiency based on yield per hectare has the highest yield at dose of 300 kg urea/ ha that is equal to 1,76. While giving urea fertilizer at dose 0, 50, 100, 150, 200, and 250 kg/ ha shows the efficiency of land use amounted to 1,18; 1,20; 1,31; 1,53; 1,66; and 1,44. Keywords : Corn plant, Double row, and Urea Fertilize,. Disubmit : 3 Mei 2018 Diterima: 21 Mei 2018 , Disetujui : 21 Agustus 2018
