L'effet de quelques facteurs abiotiques sur la fusariose vasculaire du pois chiche causé par Fusarium oxysporum F.sp.CICERIS

Abstract

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.
