The results showed that intercropping of corn and peanuts were able to utilize land use. 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. Diversity tested with Barlett test, the properties of the additive or the data additive were tested by the tukey test. The design used in this study is design of group randomized perfect with three replications and nine treatments. 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.

There is no interaction between species and density of weeds in influencingthe growth and production of maize.Keyword: maize, weeds, competitionĮfikasi Herbisida Campuran Atrazin Dan Mesotrion Untuk Mengendalikan Gulma Pada Budidaya Tanaman Jagung ( Zea Mays L.) The density of 40 weeds/m2affects weight of 100grains, but the density of 10, 20, and 80 weeds/m2did not affect the growth and productionof maize. The result showed that : (1).Species of weeds affects plant shoot dry weight, the weight of maize cobs, and the weight ofgrain maize but did not affect plant height, number of leaves, plant populations, cob length,cob diameter, and weighs 100 grains. If the assumptions are met, the data is analyzed using ANOVA,followed by Least Significant Difference Test (LSD) 5%. The second factor is 5 weed density that are 0, 10, 20, 40, and 80populations of weeds/m2. The treatments arranged factorial (3x5) in a strip plot design with three replications.The first factor is the species of weed that are Asystasia gangetica, Rottboelia exaltata, andCyperus rotundus. The research was conducted in Natar, South Lampung and WeedLaboratory Faculty of Agriculture, university of Lampung from December 2014 to April2015. Interaction between the type and density of weeds in influencing the growth andproduction of maize. The effect of weed density on the growth and production of maize,(3). The effect of weeds species on the growth andproduction of maize, (2). Weeds is animportant issue because it can compete with the main crop that can reduce crop production.The purpose of this research to determine: (1). Maize production in each year tends to decrease.
