The effect of trichoderma harzianum dose and shallot population (Allium cepa L.) on chili production (Capsicum annuum L.) by intercropping system

Abstract

Trichoderma harzianum is a soil fungus that plays a role in decomposing soil organic matter, and contains several components of substances such as N, P, S and Mg and nutrients needed by plants for their growth. Intercropping is one way to increase the efficiency of land use by planting several types of plants on the same land and at the same time. Meanwhile, to increase land use efficiency and reduce the risk of chili farming failure, it can be achieved by implementing an intercropping system of chili with shallots. The research aimed to determine of T.harzianum dosage and the shallots population (Allium cepa L.). The interaction between these on the chili production (Capsicum annuum L.) by intercropping system. The experimental design used was Randomized Block Design 4 × 3 factorial with three replications. Threre were interactions between T. harzianum dosage and shallots population on fruits number per plant, fruit weight per plant and fruit length per plant. The best result were found at 20 g per plant T. harzianum dosage and two shallots population on fruits number per plant (153,33 fruit), fruit weight per plant (121,55 g) and fruit length per plant (126,41 cm).
