Abstract

West Sumatra was declared as a center for Indonesian cocoa in the western portion. Almost all areas in West Sumatra are suitable for cocoa cultivation, so the cocoa planting area covers almost all the districts in the province. However, West Sumatran Cocoa production decline occurs because cocoa plantations are still mostly cultivated with smallholder plantations. The occurrence of land conversion and reduced land carrying capacity, including soil fertility, is due to the continuous use of inorganic fertilizers, which results in a decrease in the ecological quality of the land. Efforts to improve land conditions biologically by utilizing soil biotechnology. One of the soil microbes that can be utilized is Arbuscular Mycorrhizal Fungi (AMF). AMF that live in a symbiotic mutualism with plant roots and helps the absorption of plant nutrients and live in various places. The study aimed to identify arbuscular mycorrhiza Cocoa rhizosphere three districts, West Sumatra province, from the month of November 2020 to May 2021. The results showed the number of spores and diversity of AMF. The number of spores was 67-218 spores per 20 g soil. The root colonization was in the range of 21.3 - 24.6%. While the AMF diversity before trapped found three types of sport Glomus sp., Acaulospora sp., dan Gigaspora sp

Abstract

There is ample opportunity for cocoa (Theobroma cacao L.) plantations because the world demand for cocoa increases every year. Cocoa plants bear fruit every year without knowing the season so cocoa cultivation provides promising prospects. The demand for cocoa must be balanced with increased in production from the cultivation scale from providing seeds to expanding cocoa planting land. The experimental design used in this study was a two-factor Randomised Group Design, namely the provision of AMF F0 (without AMF) and F1 (with AMF). The second factor is cocoa waste compost in planting media (v/v) with five levels, namely k0 (0%), k1 (5%), k2 (10%), k3 (15%),and k4 (20%). The aim of the research was to see the effectiveness of AMF and cocoa waste compost on the growth of cocoa seedling. Based on the research results, it can be concluded that the treatment of FMA can increase plant height, root volume, root dry weight, and percentage of colonized roots. Cocoa seedlings gave the best response with a dose of 0% cocoa waste compost with AMF treatment, with an average height of 60.19 cm . The percentage of AMF colonization is high at 44.6%. The final soil analysis showed an increase in P-available pH and soil Ald with mycorrhiza and cocoa shell compost treatment at a dose of 10%
