Allelochemicals in sorghum (Sorghum bicolor L. Moench) as bio-inputs for weed control

Key Points

The research aims to assess the herbicidal properties of sorghum and its role in sustainable weed management.
Conducted field experiments using a completely randomized design.
Compared sorghum cultivation with corn cultivation in separate main plots.
Sowed soybeans in main plots following harvest and tested weed control in designated sub-plots.
Sorghum allelochemicals significantly altered soil microbiology.
Reduced weed density was observed in plots with sorghum.
Sorghum inhibited weed growth and development effectively.

Abstract

This study aimed to evaluate and identify the potential herbicidal activity of sorghum plants. The field experiments were done in completely randomized design with Main Plots and sub-plots. The experimental area was divided into two Main plots, in one plot sorghum was cultivated and in second plot corn (Zea mays L.) was cultivated under no-till system for straw. After the harvest of sorghum and corn, soybeans were sown in Main Plots, and weed control test was done in sub-plots (1.5 x5.0 m). This study aimed to develop sustainability through the use of renewable resources. The allelochemicals present in sorghum significantly changed the soil microbiology, reduced weed density restricted the growth and development of weeds
