Agronomic Response of Soybean Accession at Two Spacings

Abstract

The key to optimizing plant productivity is superior plant varieties combined with proper plant management. The purpose of this study was to learn about the responses of various soybean accessions to different spacings. During the dry season of 2019, the research was conducted in Genteng, Banyuwangi research station. The study employed a split plot design with two factors, which was repeated three times. The main plot was the planting method: (1). 2:1 double rows = 50 cm x (30 cm x 15 cm) (2) Single row: 30 cm x 15 cm spacing. 15 soybean accessions were used as sub-plots. Six accessions have the potential to produce seeds greater than 3 t ha-1 based on productivity per hectare. Differences in plant spacing influenced plant height, internode length, number of branches, and seed weight. Longer stems and nodes distinguished the single row. The seed yield per plant was higher in double rows than in single rows.
