Soybeans are a versatile and widely grown crop, offering numerous benefits to both farmers and consumers. In recent years, there has been a growing interest in harvesting green-stem soybeans, as they provide several advantages over traditional dry beans. Green-stem soybeans have higher yields, improved nutritional content, and reduced shattering losses. This article aims to provide case combine operators with strategies and guidelines for efficiently harvesting green-stem soybeans.
Timing is Key
The timing of harvesting green-stem soybeans plays a crucial role in optimizing yield and quality. It is recommended to start harvesting when the pods are fully developed but still green and pliable, with beans inside beginning to firm up. Waiting too long can result in shattering losses, while harvesting too early may lead to decreased yields and lower seed quality. Regular monitoring of the crop’s moisture content and maturity is essential to determine the ideal harvest time.
Equipment Considerations
Case combine operators should ensure their equipment is properly adjusted and suited for harvesting green-stem soybeans. Consider the following factors:
a. Cutting Height: Set the cutter bar height slightly higher than usual to minimize the risk of soil and debris being collected with the plants. A cutting height of around 6-8 inches is generally recommended.
b. Reel Speed and Position: Adjust the reel speed to match the forward ground speed. Position the reel so that it gently pushes the plants toward the cutter bar without excessive contact. This helps prevent shattering and ensures an even flow of plants into the combine.
c. Combine Settings: Fine-tune the combine settings to handle green-stem soybeans effectively. Adjust cylinder speed, concave clearance, and fan speed to accommodate the increased moisture content and pliability of the plants. Regularly monitor and adjust these settings as needed throughout the harvesting process.
Harvesting Techniques
To maximize efficiency and minimize losses during the harvesting of green-stem soybeans, consider the following techniques:
a. Maintain Consistent Ground Speed: Keep a steady and consistent ground speed while operating the combine. This allows for a uniform flow of green-stem soybeans into the machine and promotes efficient threshing and separation.
b. Minimize Stops and Turns: Reduce unnecessary stops and turns in the field to minimize the potential for shattering losses. Plan your harvesting route carefully, taking into account the field’s layout and any obstacles that may hinder smooth operation.
c. Monitor Grain Tank Fill Level: Regularly monitor the grain tank fill level to prevent overfilling, which can result in seed damage and losses. Unload the grain tank before it reaches its maximum capacity to maintain efficient operation.
Post-Harvest Considerations
Once the harvesting is complete, it is essential to properly handle and store the harvested green-stem soybeans. Prompt drying and conditioning are necessary to reduce moisture content and prevent spoilage. Utilize appropriate storage facilities and implement proper aeration and temperature control measures to maintain the quality and marketability of the harvested crop.
Conclusion
Harvesting green-stem soybeans can offer significant advantages in terms of increased yields, improved nutritional content, and reduced shattering losses. Case combine operators can optimize their harvest by considering the timing, equipment adjustments, harvesting techniques, and post-harvest practices outlined in this article. By implementing these strategies, operators can achieve efficient and successful harvesting of green-stem soybeans, contributing to enhanced profitability and sustainability in soybean production.
