Irrigation management methods for the production of bell pepper in agricultural substrates

Abstract

This study's objective was to assess the response and effectiveness of irrigation management systems for the production of bell pepper with different agricultural substrates, under protected conditions. The current study was conducted in a greenhouse located in Juazeiro, BA, in the northwest of Brazil. The experiment design was completely randomized in a split-plot system, with two irrigation treatments as the main plots (the drainage lysimeter and the Piché evaporimeter) and two substrates in each sub-plot (coconut fiber and pinus bark), with 5 replications per treatment. Harvest was conducted from 86 to 151 days after transplanting, and the following characteristics were evaluated: total, marketable and unmarketable yields, production per plant, fresh mass of fruits, fruit number per plant, length and diameter of fruits, length/diameter ratio, water use efficiency, pulp thickness, fruit pH, soluble solids, and titratable acidity.

Leaf water potential for surface and subsurface drip irrigated bell pepper under various deficit irrigation strategies

“…Ferrara et al (2011) reported that pepper yield decreased gradually from the full irrigation to the treatment stressed during the vegetative phase, and the lowest yield in the treatment stressed during the reproductive growth phase. Santos et al (2018) determined the total cumulative mean yield for the three harvests was 14.59 t ha -1 for the lysimeter-based system and 13.76 t ha -1 for cultivation using pinus bark. Koksal et al (2017) reported a maximum average yield of 42.4 t ha -1 for fully irrigated red peppers in the Northern part of Turkey.…”
