Effect of compost enrichment with Trichoderma sp on the growth of Arabica coffee seedlings

Abstract

Abstract An experiment was conducted to determine and study the effect of adding Trichoderma sp. on compost for the growth of Arabica coffee seedlings ( Coffea arabica L.). The research design was a complete randomized design (CRD) of a two-factor factorial pattern. Compost was the first factor consisted of 4 levels: 0 g per polybag, 100 g per polybag, 200 g per polybag, 300 g per polybag, and Trichoderma sp addition as the second factor consisting of 4 levels, namely: 0 g per polybag, 1 g per polybag, 2 g per polybag, 3 g per polybag. The results showed that the compost dosage of 300 g / polybag gave the best results on average leaf area parameters (22.22 cm), stem diameter (3.27 mm), and the highest percentage of succesful shoot grafting which was 86.11%. Addition of 2 g Trichoderma sp. per polybag gave the best results on leaf area at the age of 6 week after planting of 6.38 cm.
