Optimizing Soil Health and Sorghum Productivity through Crop Rotation with Quinoa

Area of Science:

• Agricultural Science
• Agronomy
• Soil Science

Background:

• Continuous sorghum cropping can degrade soil quality and reduce crop yield.
• Crop rotation is a sustainable practice to improve soil health and agricultural productivity.

Purpose of the Study:

• To evaluate the impact of sorghum-quinoa crop rotation versus continuous sorghum cropping on soil properties and sorghum yield.
• To assess the potential of quinoa as a rotation crop for enhancing sorghum production.

Main Methods:

• A two-year field experiment comparing continuous sorghum and sorghum-quinoa rotation.
• Randomized complete block design with three replicates.
• Analysis of soil physicochemical properties and sorghum yield traits.

Main Results:

• Sorghum-quinoa rotation increased soil total nitrogen and organic matter, especially at later growth stages.
• Continuous cropping resulted in higher available phosphorus levels.
• Crop rotation significantly improved sorghum yield traits, including grain yield per hectare.

Conclusions:

• Sorghum-quinoa rotation enhances soil fertility and sorghum productivity compared to continuous cropping.
• Crop rotation offers a viable strategy for sustainable sorghum cultivation.
• Further research is needed to determine long-term effects and optimize management.
