Tropical Cover Crop Comparison Chart – Rankings by Purpose

Overview

Choosing the right cover crop requires matching species characteristics to your specific objectives. This comparison ranks the major tropical cover crop species across key criteria: nitrogen fixation, weed suppression, erosion control, biomass production, cost, and ease of management.

Details

For nitrogen fixation: Sesbania > Crotalaria > Mucuna > Cowpea > Lablab. For weed suppression: Mucuna > Lablab > Sesbania > Crotalaria > Cowpea. For erosion control: Mucuna > Cowpea > Lablab > Crotalaria > Sesbania. For biomass production: Sesbania > Crotalaria > Mucuna > Lablab > Cowpea.

Why Choose Us

Sesbania ranks first or near-first in nitrogen fixation and biomass production — the two most important criteria for soil fertility restoration. Its primary limitation is its preference for moist to waterlogged conditions, which makes it less suitable for dryland farming. Contact us for sesbania seeds and cover crop advisory services.
