Résumé:
This work aims to determine the impact of certain abiotic factors on the fusarium fungus
(vascular wilt of chickpea) from the collection of 8 samples from different regions of northern
Algeria during the 2015 season.We performed experiments in plastic greenhouses, where we
noticed the spread of the disease, and the value of the AUDPC was high in the zone 1 (4081)
and in the Zone 2 (4098.5), unlike areas 4.7, 8, where there was low AUDPC rate (1300,
1372,and1229)respectively.
The results showed changes in growth factors, yield, dry weight, weight of rizuma, so we
recorded a negative correlation between the percentage of AUDPC and tau rizuma, where we
got a good return and acceptable dry weight.
The research of the effects of AUDPC mineral elements showed a positive relationship with
phosphorus available for absorption of the plant. We also did not score any relation with total
phosphorus, or the amount of nitrogen is significantly elevated during the resistance of
chickpea disease.
