摘要
提高大豆 [Glycine max L. (Merrill)] 的产量在很大程度上依赖于优化作物的几何形状,包括行间距和行内距。这一重要的农艺实践直接影响大豆作物的产量,因此农民在确定最佳作物几何形状时,必须考虑大豆成熟度组别。因此,本研究旨在确定行间距和行内距对大豆品种产量和产量成分的影响,并为每个大豆品种成熟度组确定适当的株距,以实现研究区大豆的高产。在随机完全区组设计中,每个成熟度组的两个大豆品种、四种行间距(30、40、50 和 60 厘米)和两种行内距(5 和 10 厘米)按因子组合排列,三次重复。结果表明,大豆品种各成熟组的开花天数、成熟天数、株高、每荚种子数、每荚株数和百粒重受品种、行间距和行内距主效应的显著影响。早熟组和中熟组窄行距的谷物产量最高,而晚熟组 50 厘米行距的谷物产量最高。因此,在奥罗米亚西部地区和类似的农业生态中,早熟和中熟大豆品种建议采用 40 厘米的行距,晚熟大豆品种建议采用 50 厘米的行距。
Optimizing crop geometry for enhanced growth and yield of soybean [Glycine max L. (Merrill)] maturity groups in western Ethiopia
Increasing soybean [Glycine max L. (Merrill)] productivity relies heavily on optimizing crop geometry, encompassing both inter- and intra-row spacing. This crucial agronomic practice directly impacts the productivity of soybean crops, making it vital for farmers to consider soybean maturity group when determining optimal crop geometry. Hence, the study was conducted to determine the effect of inter- and intra-row spacing on yield and yield components of soybean varieties and to determine appropriate plant spacing for each maturity group of soybean varieties to achieve a high yield of soybean in the study area. Two soybean varieties from each maturity group, four inter-row spacing (30, 40, 50, and 60 cm), and two intra-row spacing (5 and 10 cm) were arranged in factorial combinations in randomized complete block design with three replications. The results showed that days to flowering, days to maturity, plant height, number of seeds/pod, number of pods/plant, and 100-seed weight were significantly influenced by the main effect of varieties, inter- and intra-row spacing for each maturity group of soybean varieties. The highest grain yield was recorded from narrow inter-row spacing for early and medium maturity groups regardless of intra-row spacing while the highest grain yield was obtained from 50-cm inter-row spacing for late maturing groups. Thus, it can be concluded that 40-cm inter-row spacing is recommended for early and medium soybean varieties, while 50-cm inter-row spacing is recommended for late-maturing soybean varieties for western parts of Oromia and similar agroecologies.
