Pertumbuhan dan Hasil Kedelai (Glycine Max L. Merril) pada Beberapa Jarak Tanam Jagung dalam Sistem Tumpang Sari

Abstract

<em>The objective of the experiment was to observe the best plant spacing of corn to increase the growth and yield of soybean under intercropping system. The experiment was conducted from December 2008 to March 2009 at Jambi University� experimental station. The experimental design was randomized complete block design� with four replications. These treatments were intercropping corn and soybean� with plant spacing of corn : 75 cm x 25 cm, 75 cm x 50 cm, 100 cm x 25 cm, 100 cm x 50 cm, 150 cm x 25 cm and 150 cm x 50 cm. The results showed that the plant spacing of corn under intercropping system affected the height of� soybean, yield of soybean, yield of corn and Land Equivalent Ratio (LER), but did not� affect the� dry weight of the upper part of soybean plant,� number of� pods per soybean plant, number of filled pods per soybean plant, 100� grains weight of soybean and 1000 grains weight of corn. The plant spacing of corn 75 cm x 25 cm under intercropping system produced better growth and yield of soybean than the other treatments with LER at 1,454.</em>
