## Abstract
&lt;p&gt;&lt;span lang="EN"&gt;This study aims to evaluate the effectiveness of &lt;em&gt;Trichoderma asperellum&lt;/em&gt; and &lt;em&gt;Azotobacter chroococcum&lt;/em&gt; in providing nutrients and nutrient uptake after treatment inarching grafting on cocoa trees' rehabilitation efforts. The Split Plot Design, with two factors, namely the application of &lt;em&gt;T. asperellum&lt;/em&gt; and &lt;em&gt;A. chroococcum&lt;/em&gt; were repeated three times and continued using ANOVA and Tukey HSD at a 5%. Rehabilitation of cocoa plants that are relatively old age can be done without the need to cut down a cocoa tree, by way of modification &lt;em&gt;Inarching grafting&lt;/em&gt; with environmentally friendly farming systems, so that farmers do not need a long time to produce cocoa beans. This research concluded that the &lt;em&gt;inarching grafting&lt;/em&gt; method can be used to rehabilitate cocoa plants of relatively old ages and damage, with applications, &lt;em&gt;T. asperellum&lt;/em&gt; (4 g/l) and &lt;em&gt;A. chroococcum&lt;/em&gt; (4 × 10&lt;sup&gt;8&lt;/sup&gt; CFU/ml) the dose of 40 ml per plant with a frequency of twice application to each plant. This treatment is the best interaction that can reduce the number of young fruits falling (74.15%), boost the number of flowers (264.71%), the number of young fruits formed (271.65%), and the number of surviving fruits (117%) and production.&lt;/span&gt;&lt;/p&gt;
