Sugarcane residues soil amendments for crop improvement and citrus nematode Tylenchulus semipenetrans management on mandarin under sandy (Calcareous) soil condmons [electronic resource].

Includes references.

Sugarcane residue soil amendments for crop improvement and citrus nematode, Tylenchulus semipenetrans management on mandarin were studied under sandy (calcareous) soil conditions, Molasses and vinasse as sugarcane residues each was applied twice compared to the nematicide, oxamyl 24% L on March and 60 days after the first application (on May) at 1/10 and 1/20 dilutions. The two tested materials significantly (P::S; 0.01 and 0.05) decreased nematode population in soil and root especially at midseason by 97.7 % and 97.3 % for molasses and vinasse at the highest concentration, respectively. At harvest stage, the nematode population especially at the lowest concentration of both materials tended to build up again compared to the untreated check. The two tested materials resulted in 80.8 and 69.2 % increases in fruit yield per feddan for molasses and vinasse at the highest concentration, respectively.
