Growth dynamics of paprika plants (Capsicum annuum L.) subjected to the application of Trichoderma harzianum Rifai in controlled environments

Abstract

The purpose of this work is to evaluate the growth of paprika plants (Capsicum annuum L.) under controlled conditions under the effect of Trichoderma harzianum Rifai. For this purpose, non-linear models were considered, including: logistics and gompertz. The test was carried out in Crop Houses under controlled conditions applying a treatment design (two treatments and three (3) repetitions). Treatment T1: Application of a dose of 100 g of the fungus Trichoderma prior to sowing. Treatment T2: Application of a dose of 100 g of the fungus Trichoderma after sowing. The following variables were measured: plant length (cm), stem diameter (cm) and foliar area (cm²) every 15 days from the time of transplantation. The results showed that the logistical model should be considered only to adjust height data for paprika plants to which a dose of the fungus Trichoderma was applied prior to sowing, while for the rest of the variables and other experimental conditions it is advisable to use the gompertz model. Similarly, when a dose of the fungus Trichoderma was applied to paprika plants prior to sowing, there was a higher intrinsic growth rate, lower maximum growth and the plants took longer to slow down growth at a height but less time to slow down the development of the foliar area. While when a dose of the fungus Trichoderma was applied after sowing the plants reported a higher intrinsic growth rate, lower maximum growth took less time to slow down growth in diameter
