Abstract
The present study aims to evaluate the influence of plant spatial arrangement and water supplementation on soybean yield for the 2020/21 crop year, in the edaphoclimatic conditions of the central region of Rio Grande do Sul (Brazil). The field experiment was installed in an experimental area of the Rio Grande do Sul State University (UERGS) in the city of Cachoeira do Sul. Supplementary irrigation provided positive increases in soybean yield between 13% (row spacing of 0.75 m) and 35% (row spacing of 0.50 m). The conventional row spacing of 0.50 m can be recommended as a spatial arrangement strategy for both irrigated areas (productivity 5,196.6 kg ha-1) and rainfed areas (productivity 3,360.0 kg ha-1), optimizing costs regarding the mechanization of farming.
本研究旨在评估在南里奥格兰德州（巴西）中部地区的土壤气候条件下，2020/21作物年植物空间安排和水分补充对大豆产量的影响。现场实验安装在 位于Cachoeira do Sul市的南里奥格兰德州州立大学（UERGS）。补充灌溉使大豆产量增加了13%（行距0.75米）至35%（行距0.50米）。对于灌溉区（生产力5196.6 kg ha-1）和降雨区（生产力3360.0 kg ha-1。
