“…This study was conducted using Split Plot Design, with two factors and three replications, with treatment as the main plot inoculation asperellum Trichoderma consisted of four levels, i.e., without T.asperellum (T0), inoculation T.Asperellum one application (T1), two application (T2) and three application (A3) each of 4 g L -1 for each cocoa seed [9]. The first application is given when applying compost (made from cocoa pod husks, banana stems, and gliricidia leaves) in each planting hole.…”

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 cm 2 , the number of stomata was 62.72 pieces/area of view, the stomata density was 3085,19 n/mm 2 , 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.

“…Hasil penelitian sebelumnya menyatakan bahwa pemberian Trichoderma asperellum dengan dosis 4 g L -1 pada setiap semaian kakao, mampu membantu mengatasi persaingan dalam pemanfaatan unsur hara dan air serta faktor penghambat pertumbuhan lainnya, dan berpengaruh terhadap pertumbuhan vegetatif semaian kakao yang ditanam di sekitar pohon kakao tua (Palad et al, 2016).…”

Usaha yang dapat dilakukan untuk megatasi penurunan produksi pohon kakao tua dan rusak adalah penerapan inarching grafting atau penyambungan tanaman kakao muda unggul berumur minimal 6 bulan yang ditanam di sekitar pohon tua. Tujuan penelitian ini adalah mengkaji pengaruh aplikasi Trichoderma asperellum dan Azotobacter chroococcum terhadap pertumbuhan vegetatif semaian kakao yang akan disambungkan ke pohon kakao tua menggunakan metode inarching grafting. Penelitian ini menggunakan Rancangan Petak Terbagi dengan tiga ulangan. Petak Utama yaitu aplikasi T.asperellum sebanyak 4 g L-1 setiap tanaman, dengan empat taraf: tanpa T.asperellum (T0), satu kali (T1), dua kali (T2), dan tiga kali (T3) aplikasi. Anak Petak adalah inokulasi A.chroococcum sebanyak 40 ml x 108 cfu setiap tanaman, dengan 3 taraf: tanpa A.chroococcum (A0), satu kali (A1) dan dua kali (A2) aplikasi. Hasil analisis menunjukkan tidak terdapat interaksi antara aplikasi T.asperellum dengan A.chroococcum, tetapi terdapat pengaruh tunggal dari kedua mikroba potensial yang diaplikasikan. Pada umur semaian 90 hst, aplikasi dua kali A.chroococcum menghasilkan rata-rata tinggi tanaman 155,25 cm, total daun 41 helai dan diameter batang 13,10 mm. Pemberian tiga kali T.asperellum menghasilkan rata-rata tinggi tanaman 150,89 cm, total daun 41,22 helai dan diameter batang 12,86 mm. Semaian yang diberi mikroba potensial digunakan untuk rehabilitasi pohon kakao tua. An efforts that can be done to overcome the decline in production of old and damaged cocoa trees are the application of inarching grafting or grafting of superior young cocoa plants with a minimum age of 6 months planted around old trees. The purpose of this study was to examine the effect of the application of Trichoderma asperellum and Azotobacter chroococcumon the vegetative growth of cocoa seedlings which was grafted to old cocoa trees using the inarching grafting method. The research used a Split Plot Design with three replications. The main plot was application of T.asperellum of 4 g L-1 for each seedling and cocoa tree, consisted of four levels. i.e: without T.asperellum (T0), one time application (T1), two times application (T2), and three times application (T3). The subplot factor was A.chroococcum as much as 40 ml x 108 cfu on each seedling and cocoa tree, consisted of three levels, i.e.: without A. chroococcum (A0), one time application (A1) and two times application (A2). The analysis of variance results showed that no interaction between applications of T.asperellum with A.chroococcum, but it had a singular effect for both potential microbial applied. At 90 days after planting, the application of A.chroococcum twice resulted in an average plant height of 155.25 cm, a total of 41 leaves and a stem diameter of 13.10 mm. Application of T.asperellum three times resulted in an average plant height of 150.89 cm, the number of leaves 41.22 sheets and a stem diameter of 12.86 mm. The seedlings that inoculated with potential microbes can be used for rehabilitation of old cacao trees.

Damping off is one of the diseases caused by soil-borne pathogens resulting in the death of seedling in a short time. Control of this disease is quite difficult. The study aimed to examine the potential of biofertilizers and the time of application to damping off disease intensity and plant growth on Japansche citroen seedling. This study used a Factorial Completely Randomized Design with two factors: 1). Biofertilizer namely AzzoFor (P1), liquid biofertilizer (P2), a secondary metabolite of Trichoderma asperellum (P3), the mixture of three biofertilizers (P4), and control (P5), 2). The time of application, namely the treatment of biofertilizers first then followed by the inoculation of F. oxysporum. (A1) and the treatment of F. oxysporu first followed by treatment of biofertilizer (A2). The results showed that the lowest disease intensity was found in A1P3 treatment (0%), while in control reached 41.3%. The treatment of A1P2, A2P1, A2P2 and A2P4 showed the same disease intensity. The highest disease control effectiveness found in A1P2, A1P3, A2P1, A2P2 and A2P4 treatments and this was significantly different compared to A1P4, A2P3 and control treatments. The most significant percentage of seeds germinate at 21 DAS was shown in A1P1 treatment (26.7%) and A2P3 treatment (25.3%), while after 28 DAS, it was in A2P4 treatment (73.3%). The lowest plant height at 28 DAS was A1P4 treatment and control. Biofertilizer is useful for controlling the damping-off disease if applied separately.
