- Abstract
The aim of this study was to examine the effect of Trichoderma asperellum and Azotobacter chroococcum applications on the rehabilitation of the roots of side-grafted cocoa plants using the inarching grafting method against the state of stomata. The method used in this study was a split-plot design, with two factors, namely the application of Trichoderma asperellum and Azotobacter chroococcum which were repeated three times each and continued by using the Tukey’s test. The results showed that the inoculation of Trichoderma asperellum and Azotobacter chroococcum in the rehabilitation of cocoa roots by inarching grafting had a very significant effect on the stomata of the leaves so that it had the potential to extend the life of the cocoa plants with optimal productivity, without logging the relatively old cocoa trees. The best results obtained were the leaf area was 181.30 cm2, the number of stomata was 62.72 pieces/area of view, the stomata density was 3085,19 n/mm2, and the stomata aperture width was 228,07 μm in the inoculation of Azotobacter chroococcum bacteria two times application, and Trichoderma asperellum three times of application using the inarching grafting method which is done at the time of the appearance of the flush.
