Purpose: This experiment was conducted in order to investigate the planting dates before and after the first effective rainfall and to compare different mechanical and chemical management methods with hand weeding and non-hand weeding of weeds in the autumn chickpea field in Kermanshah.
Methodology: The experiment was carried out as factorial based on a randomized complete block design with four replications at the Dryland Agricultural Research Sub-Institute for two years from the fall of 2021. The treatments were included planting dates: 1- before the effective rainfall, 2- after the effective rainfall, along with the integrated management of weeds in the chickpea field, including 1- Treflan + Gallant Super 2- Treflan + mechanical control 3- Treflan + Gallant Super + mechanical control 4- Weeding manual and 5- non-weed control.
Findings: With the use of Treflan and Gallant Super herbicides and mechanical control, chickpeas can be cultivated in the fall and before the effective rainfall.
Innovation: Autumn cultivation of chickpea before effective rainfall and use of Treflan pre-sowing herbicide
Conclusion: After manual weeding, the highest average of seed yield in the first and second years was obtained in the chemical control method (Treflan + Gallant Super) + mechanical control with averages of 464 and 1143 kg per hectare, respectively. The lowest average of total number and total dry weight of weeds in the field of autumn chickpea after hand weeding was related to planting date before effective rainfall treatment and the integrated management of Treflan + Gallant Super + mechanical control.
