Abstract

This study aims to determine the effect of the interaction between the application of Trichoderma solid formula biopesticide applied to the soil and through canopy spraying on the growth and health of vegetative phase cayenne pepper (Capsicum frutescens) plants. This study was conducted from September to December 2024 in Pacet, Pasinan Hamlet, Cepokolimo Village, at an altitude of 450 meters above sea level. This field study was designed as a factorial Randomized Block Design. The first factor was the application of solid biofertilizer (soil treatment), which consisted of three levels: no biofertilizer application but using complete chemical fertilizer; soil treatment at planting or starting from sowing; and soil treatment one month after planting. The second factor was the application of liquid Trichoderma biofertilizer. The observation variables were length increase (cm), leaf number increase, average time of first flowering (days), branch increase, and plant health. The interaction effect of biopesticide application through soil treatment had a significant effect on plant health with a disease symptom intensity of 9.38% compared to the control of 16.67%. The interaction effect on plant growth was not significant.

Abstract

This study aims to examine the effect of Trichoderma biofertilizer formulated with husks or biochar applied to the soil as fertilizer and biofertilizer sprayed on the canopy surface on the vegetative growth of soybean plants in saline soil. The study was designed as a factorial design with a randomized block design (RBD). The first factor was the application of biofertilizer as soil fertilization, consisting of: no biofertilizer (NPK fertilization) and biofertilizer with husk and biochar as carriers. The second factor was the spraying of biofertilizer on the canopy, consisting of: no spraying and spraying. Data on height, stem diameter, number of leaves, and time of flower emergence were analyzed using 5% ANOVA followed by 5% BNJ test. There was a significant interaction effect on plant height, stem diameter, and number of leaves at 42 and 56 days after planting. The combination of Trichoderma biofertilizer with husk carrier and canopy spraying produced the highest plant response in terms of plant height (53.19±3.51 cm), stem diameter (0.53±0.02 cm), and number of leaves (9.50±0.65 leaves), as well as earlier flowering (37.50±0.33 days). The application of Trichoderma biofertilizer formulated with rice husk as a carrier has the potential to be used in fertilizing soybean plants grown in saline soil.

Abstract

This study aims to examine the effect of the combination of Trichoderma biofertilizer and liquid micro-nutrient fertilizer sprayed on the canopy at different time intervals and their interaction on the vegetative growth of rice plants. The treatments in this experiment were arranged factorially in a Randomized Block Design (RBD). The first factor was the combination of liquid micro-nutrient fertilizer and Trichoderma, consisting of without and with liquid fertilizer combination, while the second factor was the spraying interval, consisting of every week, every two weeks, and every three weeks. The experiment was repeated four times, resulting in 24 experimental units. The plant growth variables observed were plant height, number of tillers, and number of panicles. The interaction between the combination of liquid micro-nutrient fertilizer and Trichoderma and the spraying interval on the canopy significantly increased plant height but did not significantly affect the number of tillers and the maximum number of panicles. Spraying liquid biofertilizer and liquid microfertilizer every three weeks showed the highest results at a height of 55.27 cm. The combination of biofertilizer and microfertilizer has the potential to be applied to increase rice production.
