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

Abstract

Red chili as one of the important horticultural crops cultivated commercially, this is because in addition to chili has a fairly complete nutritional content, it also has a high economic value which is widely used both for household consumption and for the food industry. Therefore, it is necessary to apply intensification technology to increase chili production. These technologies include the application of Plant Growth Promoting Rhizobacteria (PGPR) to increase soil fertility and the application of shoot pruning to increase branching of chili plants. The purpose of this study was to determine the effect of PGPR and Trichoderma sp. And the treatment of shoot pruning on the production of red chili plants.This research was conducted at the Jember State Polytechnic Greenhouse, Sumbersari District, Jember Regency with an altitude of ± 89 masl. 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. The second factor was the time for cutting shoots, consisting of 3 levels of treatment. The observation variables is productivity of chili. The results showed that branch pruning and biological agent treatment did not significantly increase the production of chili plants. However, there is a tendency for better treatment with pruning and without biological agents.
