The effect of Biofertilizer Application and Shoot Pruning on the Growth of chili plants on sandy media

Abstract

This study aims to determine the effect of PGPR, Trichoderma sp and shoot pruning treatment on the growth and production of red chili plants. This study used a complete randomized block design (CRD) factorial consisting of 2 factors. The first factor was the provision of biological agents consisting of 4 levels of treatment: 1) control, 2) PGPR, 3) Trichoderma sp, and 4) PGPR and Trichoderma sp. The second factor was the time for cutting shoots, consisting of 3 levels of treatment: 1) without pruning; 2) Pruning shoots at the age of 14 days after planting, 3) Pruning shoots at the age of 21 days after planting in pots. The observation variables included plant height, fruit weight per sempel, number of fruits per sample, fruit length, and fruit diameter. The result shows of combination treatment  PGPR and Trichoderma sp  and pruning 14 DAP is the highest growth and production.
