Abstract

Limited planting land leads to the use of double-cropping systems for food crop production. This experiment aims to determine the yield and initial vigor of soybean seeds harvested from double planting of cassava-soybean with different cassava planting intensities. This experiment was conducted at the Vegetable Seed Management Unit, Sekincau Village, and the Seed and Plant Breeding Laboratory, Faculty of Agriculture, University of Lampung, from June 2022 to February 2023. Soybean variety Dega-1 and cassava clone Ketan were planted singly and double-planted with 4 compositions, namely 1) single soybean planting (p₁), and 2) double cassava-soybean planting with soybean planting intensities of 67% and cassava planting intensities of a) 67% (p₂), b) 78% (p₃), and 89% (p₄). Each treatment level was replicated five times in five blocks. Analysis of data variance using Minitab Ver. 17 and comparison of the mean values of treatments with Duncan's Multiple Range Test (DMRT) using Excel 2013. The intensity of cassava plants in double cropping with soybeans did not reduce soybean yield per plant or initial seed vigor, but reduced soybean seed yield per plot and increased the land equivalence value from 1.00 to 1.29-1.37.
