Strip-width determines competitive strengths and grain yields of

Index

Abstract

This study investigates the impact of different strip widths on the competitive strengths and grain yields of maize and soybean in a relay intercropping system (MSR). A two-year field experiment compared three strip-width arrangements (narrow, medium, and wide) with sole maize and sole soybean. Results showed that a medium strip width (200 cm) optimized yields for both maize and soybean, improving soybean's competitive ability without compromising maize's. This optimal width increased the total grain yield by 15% and land equivalent ratio by 22%, leading to a 99% increase in net income.
