Maize-Bean Intercropping Optimizes Silage Raw Material Quality and Yield by 90% in the Amazon

Agronomy · 2025

Key Findings

01The M+F2 association (INIA-604-Morocho + PER1003551 bean) harvested at the R4 (pasty grain) stage exhibited the highest dry matter percentage (32.36%).
02This R4 stage for M+F2 also resulted in better mixture quality with lower NDF (48.22%) and ADF (23.29%), and higher digestibility (62.10%) and protein (9.53%).
03Dry matter yields increased significantly compared to the R2 stage across all associations, with M+F1 showing a 134.16% increase and M+F2 a 90.56% increase.

Application

Design takeaway

When designing for silage production, consider intercropping maize with legumes and optimize the harvest timing to the 'pasty grain' stage for improved yield and nutritional quality.

How to apply

When developing or advising on forage production systems, recommend intercropping maize with compatible bean varieties and guide farmers on identifying the optimal 'pasty grain' stage for harvest to produce better silage.

Project actions

01When researching crop yields, consider the synergistic effects of intercropping.
02Investigate how different harvest timings affect the nutritional content of agricultural products.

Method & Evidence

AimTo evaluate the effect of intercropping maize with different bean varieties and varying maize cutting stages on the morphological variables, yield, and nutritional composition of forage intended for silage.

MethodExperimental research

ProcedureA randomized complete block design was employed to test three maize-bean associations (monoculture maize, maize with bean variety 1, maize with bean variety 2) across three maize cutting stages (blister, milky, and pasty grain). Morphological variables, yield, and nutritional composition (dry matter, NDF, ADF, digestibility, protein) of the forage were measured.

Sample27 experimental units

ContextLivestock farming in the Peruvian Amazon, focusing on forage production for silage.

Variables

IV["Maize-bean association (monoculture maize, M+F1, M+F2)","Maize cutting stage (R2, R3, R4)"]

DV["Morphological variables","Yield (dry matter)","Nutritional composition (dry matter percentage, NDF, ADF, digestibility, protein)"]

CV["Experimental design (RCBD)","Number of blocks (3)","Location (Peruvian Amazon)"]

Strengths & Limitations

Strengths

+Uses a robust experimental design (RCBD).
+Evaluates multiple critical factors (crop association and harvest stage) simultaneously.

Limitations

The nutritional analysis was performed on raw forage, not the final silage. The specific bean varieties used might not be available or suitable in all regions.

Reliability & validity

The use of a randomized complete block design with three blocks enhances the reliability and validity of the findings by controlling for environmental variability and allowing for statistical analysis. However, the study's focus on raw material and specific regional conditions may limit generalizability.

Think critically

How might the economic viability of this intercropping system compare to monoculture, considering seed costs and labor for planting and harvesting?

Design Principles

"Optimize crop associations and harvest timing to maximize the nutritional value and yield of forage for silage."

This research offers a practical strategy for livestock farmers facing climate change and land degradation. By optimizing the raw material for silage, it directly impacts feed availability, quality, and cost-effectiveness, contributing to more resilient and sustainable agricultural systems.

What This Means for Your Design

Mixing corn with beans and cutting it when the corn is 'pasty' makes better food for cows that will be turned into silage, giving more food and better nutrition.

How to use in your project

1.Use this study to justify the selection of specific crop combinations and harvest strategies in a design project focused on agricultural efficiency or livestock feed.
2.Cite this research when discussing the optimization of raw materials for food processing or preservation.

Paragraph starter

Research by Vásquez et al. (2025) demonstrates that intercropping maize with specific bean varieties, such as PER1003551, and harvesting at the 'pasty grain' stage significantly enhances forage yield and nutritional quality, making it a superior raw material for silage production. This optimization, showing up to a 90% increase in dry matter yield and improved protein and digestibility, offers a viable strategy for improving livestock feed resources in challenging agricultural environments.
