Soil solubility monitoring in response to different fertilization in bell pepper cultivation - DOI: 10.7127/rbai.v1801244

Resumo

Bell peppers (Capsicum annum L.) are one of the most consumed and produced vegetables in Brazil. One of the challenges in their production is their sensitivity to soil salinity, especially in protected cultivation where fertigation is used. The objective of this study was to monitor the development and production of Bell peppers in different saline concentrations by monitoring the soil solution. The experiment was conducted in greenhouse conditions in the city of Bauru, SP, using the Theo variety of seedlings. The design was completely randomized, with three treatments: T1 (control), T2 (recommended fertilization for the crop), and T3 (fertilization with three times the crop's need). At 50 and 78 days after transplanting, the plant's biometric parameters were evaluated. Soil solution management was found to be a viable solution, given the results obtained in the development and production of pepper crops. Furthermore, treatments two and three promoted an increase in the plant's fresh and dry biomass, number of leaves, and stem diameter. However, they also caused the accumulation of salts in the soil, resulting in the loss of productivity, fruit fresh mass, and skin thickness.
