For this reason, chickpea are best suited for dryland production. If grown under irrigation, each watering after first-bud stage should be followed immediately by foliar fungicide application. Be cautious of herbicide residues when selecting fields to grow chickpea. Rotational intervals depend on how long herbicides persist in the soil, how much herbicide was applied, or how frequent herbicides were applied. The more the active ingredient of a particular herbicide has been applied the longer it will persist in the soil.
Most herbicides lose activity through chemical and biological degradation.
Critical factors that influence herbicide degradation include pH, moisture, and temperature. Because Montana has a dry climate and short growing season herbicide degradation generally takes longer than in warmer and moister areas of the country due to decreased biological activity and resulting herbicide degradation within the soil. Seeding and inoculation Plan to seed early, when spring wheat would normally be seeded. Lower populations are affordable for Kabuli, but higher populations must be planted for Desi. Plant chickpea seed 2 inches into moist soil.
