Growth response of red chilli plants to flowering phase against the application of Trichoderma and Pseudomonas fluorescens and P fertilizers

Abstract

This study aims to determine the effect of the application of Trichoderma sp. Fungi. and Pseudomonas fluorescens bacteria as biofertilizer agents and P fertilizer doses as well as interactions between microbial biofertilizer agents and P fertilizer doses on vegetative growth and early appearance of red chilli flower flowers to the initial flowering period. This greenhouse experiment was arranged factorially in a completely randomized design. The first factor was the application of microbial biofertilizer agents consisting of no microbes, Trichoderma sp., And P. fluorescens, while the second factor was the dosage of P fertilizer per 5,000 g of soil planting medium consisting of 0, 0.5, and 1.0 g SP-36. Nine combinations of treatments repeated three times to obtain 27 experimental units. The variables observed were plant height, stem diameter, leaf area, wet weight and stover dry weight at 42 days after planting (DAP) and the beginning of flower emergence. The data were analyzed by 5% ANOVA followed by a 5% HSD Test to determine the difference in influence between treatments. The results showed a very significant interaction effect between the application of microbial agents and the dose of phosphate fertilizer to height, stem diameter, leaf area, wet weight and dry weight of stover and the initial flowering time at 42 DAP. The application of P. fluorescens bacteria as a biofertilizer agent combined with 0.5 g SP-36 fertilizer dose per 5,000 g of planting media showed the highest growth effect of red chili plants at age 42 DAP in terms of plant height, stem diameter, leaf area, stover wet weight, stover dry weight, and earlier flower appearance.
