Integrating Sowing Date with Chickpea Genotypes in Managing Fusarium Wilt in Morocco
: Fusarium wilt caused by Fusarium oxysporum f.p ciceris (Foc) is a devastating soil-borne
disease of the chickpea. The disease causes crop losses in late-planted chickpeas and no available
management option currently exists to recommend to farmers. In order to determine the effect of
integrating sowing dates with chickpea genotypes on disease parameters and yield, a field experiment
was undertaken in naturally infested soil at Merchouch station during 2017–2018 and 2018–2019.
The results showed that significant differences were observed among chickpea genotypes for the
three disease parameters, and among sowing dates for final disease incidence. For seed yield,
only the sowing dates showed significant differences and all interactions between factors were
non-significant for all measured parameters. Late sowing showed high values for the three disease
parameters. A high seed yield was obtained from early-planted compared to late-planted chickpeas.
In conclusion, the integration of early sowing and chickpea genotypes with good levels of resistance
can be recommended for farmers to increase chickpea productivity in Morocco.
