These fertilizer guidelines have been developed by the University of Idaho and Washington State University based on relationships between soil tests and yield response for peas and lentils. The fertilizer rates suggested are designed to produce above average yields if other factors are not limiting yields. The fertilizer guide assumes good management. For help in obtaining a proper soil sample, confer with your Extension agricultural agent. This is accomplished by nodules formed on the roots of the chickpea plant.
Most chickpea seed is treated with captan.
This fungicide is harmful to rhizobia, so inoculating chickpea seed with rhizobia requires special handling in one of three ways. One method is to place a granular inoculum in the seed row at planting. Several companies manufacture granular inocula. The names of these companies are provided as sources for growers. The application rate should be between 5 and 10 pounds of granular inoculum per acre depending on the time since chickpeas were last planted in the field.
