The effect of chicken and mycorrhizal manure toward cacao seedling growth on ultisol soil

Abstract

Cacao plants are one of the national leading commodities after oil palm and rubber. This study aims to measure the effect of chicken and mycorrhizal manure on cacao seedling growth on ultisol soil. The method used in this study was a randomized block design consisting of two treatment factors. The given of ultisol Soil + Chicken manure (P) consisting of 4 levels: P0 about 100% (control), P1 about 25% Chicken manure + 75% ultisol, P2 about 50% Chicken manure + 50% ultisol and P3 about 75% Chicken manure + 25% ultisol. Administration of Mycorrhizal Dosage: M0 about 0 g Mycorrhiza (control), M1 about 25 g Mycorrhiza, M2 about 50 g Mycorrhiza and M3 about 75 g Mycorrhiza. Based on the results of the study, it can be stated that chicken manure treatment up to 75% and increased plant growth, number of leaves, leaf area, wet weight of seed, root volume and dry weight of seedlings, but not to the diameter of cacao seed stems. The treatment of mycorrhizal doses of up to 75 g/plant and increased plant growth, number of leaves, leaf area, wet weight of seed, root volume and dry weight of seedlings, but not to the diameter of cacao seedling stems. The interaction of chicken manure and mycorrhizal doses had no significant effect on all parameters.
