“…These results corroborate with Marinho et al (2018), with the authors considering that the pepper plants have three growth phases: vegetative, flowering-fruiting and fruit maturation. The authors consider that the duration of the growth stages of pepper crop depends on the species, the type of cultivar as well as the edaphoclimatic conditions.…”

Pepper (Capsicum sp.) is important for the Brazilian agribusiness, serving as raw material for the food, pharmaceutical and cosmetic industries. The adequate evaluation of its plants growth may help in understanding the causes of crops yield variation, with it being able to be studied by regression models, which help to adequate the management with the different phenological phases. This study aimed to compare the fit of linear Polynomial model and the Logistic and Gompertz nonlinear models in the description of pepper plants growth from the Doce cultivar. Estimates were obtained by the Gauss-Newton method, with the quality of fitted models compared by graphical analysis and evaluators: adjusted coefficient of determination (R 2 adj), Residual Standard Deviation (RSD) and the corrected Akaike Information Criterion (AICc). Residues were normal, independent and homocedastic at 5% level of significance. All models properly described the height of the Doce cultivar. The Logistic model was the most adequate according to the fitting evaluators, having higher value of R 2 adj , and lower RSD and AICc values.

“…The production of the mixture of commercial substrate + carbonized rice husk demonstrates that despite the treatment had suffered from foliar abscission at the beginning of crop fructification likely due to water stress, S2 managed to obtained higher results for the yield and water use efficiency components. Marinho et al (2016) observed that water deficit in tabasco pepper at different development phases provided smaller productivity to the plant at the vegetative stage compared to the water deficit at the reproductive phase. However, the irrigation depth that provided the most significant production at both times was 100% of the evapotranspiration of the crop, thus corroborating with this study.…”

“…Although the highest fruit production having been observed for an irrigation depth of 101.47% WHC, the best relationship between production and water applied was obtained for an irrigation depth of 69.17% WHC. Just as for production, the treatment with substrate S2 presented the best result for water use efficiency, with an and Marinho et al (2016) when assessing water use efficiency for the tabasco pepper (Capsicum frutescens), they observed that the irrigation depth of 40% crop evapotranspiration, presented the best result for WUE. In contrast, when evaluating WUE in a sweet pepper crop (Capsicum annuum L.), Ćosić et al (2015) observed that the treatment that received irrigation depth of 100% crop evapotranspiration presented the highest WUE, as well as higher production.…”

“…In this context, irrigation is also one of the most limiting factors for plant growth and development since both water Irriga, Botucatu, Edição Especial -Sul, v. 1, n. 2, p. 408-420, julho, 2021 deficiency and excess may affect such processes. Water stress may hamper the final pepper fruit production during the flowering process, causing flowers and new fruits to fall, and prevent flowers from being fertilized (MARINHO et al, 2016).…”

The present work had the primary objective of evaluating the production response and water use efficiency of the Biquinho pepper for different irrigation depths and substrates. The experiment was conducted in a greenhouse located at the Alegrete campus of the Federal University of Pampa. We performed an entirely randomized 2 x 5 two-factor experimental design (two substrate compositions and five irrigation depths). The substrate composition treatments used were a commercial substrate and the mixture of commercial substrate + carbonized rice hull. The treatments for the water replacement depths were 25, 50, 75, 100, and 125% of the water holding capacity for each substrate. At the end of the cycle, we assessed the following components: crop yield, production, water use efficiency, and fruit diameter, length, average weight, and number. The yield and water use efficiency components were more significant when using the commercial substrate + carbonized rice hull composition. The maximum technical production efficiency was obtained for an irrigation depth of 101.7% of the water holding capacity. On the other hand, the water use efficiency was higher when using a depth of 69.17%.
