Enhancing production efficiency through optimizing plant density in maize-soybean strip intercropping.

ABSTRACT:

Introduction

Due to limited arable land resources, intercropping has emerged as an efficient and sustainable production method for increasing total grain yield per unit land area. Maize-soybean strip intercropping (MSSI) technology is being widely promoted and applied across China. However, the combination of optimal density for achieving higher production efficiency of both soybean and maize remains unclear. The objective of this study was to evaluate the differences in yield, economic benefits, land, and nitrogen (N) efficiency in MSSI systems under different densities.

Methods

Five maize/soybean density combinations (67,500/97,500 plants ha^-1, D1; 67,500/120,000 plants ha^-1, D2; 67,500/142,500 plants ha^-1, D3; 60,000/142,500 plants ha
