# Optimized Harvest Management Strategy Based on Latent Loss and Antioxidant Enzyme Activity

## TL;DR

This study improves harvest timing for maize and soybean by analyzing dry matter loss and antioxidant enzyme activity to maximize yield and economic benefits.

## Contribution

The study introduces a novel approach linking latent loss and antioxidant enzyme activity to optimize harvest timing.

## Key findings

- Latent loss is common in maize and soybean, with maize losing up to 12.1036% dry matter and soybean up to 5.5742%.
- Antioxidant enzyme activity and 1000-grain weight follow similar patterns across varieties, showing initial increase, stabilization, and eventual decline.
- Optimal harvest periods are determined to enhance economic benefits and grain safety.

## Abstract

Timely harvesting is a crucial aspect of agricultural production, requiring the comprehensive evaluation of multiple factors to optimize yield and quality while minimizing economic losses and resource waste. This study systematically investigates the latent loss and changes in antioxidant enzyme activity in maize and soybean (Glycine max) to refine harvest management strategies. The findings reveal that latent loss is a universal phenomenon across different maize and soybean varieties, with maize exhibiting a dry matter loss of up to 12.1036% and soybean reaching 5.5742%. As the harvest progresses, the 1000-grain weight at standard moisture initially increases post-maturity, stabilizes gradually, and may eventually decline, while antioxidant enzyme activity follows a similar trajectory, demonstrating inter-varietal differences. Based on these findings, this study innovatively relates to latent loss and antioxidant enzyme activity. The optimal harvest period for each grain variety is determined step by step to maximize economic benefits, enhance market competitiveness, and ensure the safety and efficiency of grain production.
