Abstract

Agricultural photovoltaic (APV) systems that integrate farming activities with energy production on the same farmland face challenges due to shadowing effects caused by elevated photovoltaic (PV) panels, which hinder the spectrum necessary for photosynthesis. Spectrum splitting technology (SST) has emerged as a potential solution to balance the spectrum required for photosynthesis and PV energy generation. This study aims to investigate SST's potential in enhancing soybean physiology, quality, and yield. Four treatments were implemented: soybeans planted under a glass shed covered with multilayer film (GMF), glass shed (GS), in open-air (CK), and spectrum splitting and concentrated APV (SCAPV). Results demonstrated notable improvements in soybean physiology, quality, and yield. GMF and SCAPV treatments exhibited increased soluble sugar content by 13.5% and 4.1% compared to CK. Furthermore, GMF and SCAPV treatments showed increased oleic acid content by 5.1% and 2.1%, respectively, compared to CK. Fresh weight of grain and leaves of soybeans increased by 24.7% and 4.1% in GMF and SCAPV treatments compared to CK. At the same time, GS treatment decreased by 14.4% compared to CK. Utilization of SST in GMF and SCAPV systems presents a promising avenue to optimize soybean cultivation, improving soybean yield and quality. This study highlights the potential of SST as a solution for integrating APV systems with crop cultivation and production, leading to enhanced crop physiology, increased yield, and improved quality.
