Fruit Yield and Quality of Greenhouse-grown Bell Pepper as Influenced by Density, Container, and Trellis System

Abstract

<jats:p>Production and quality of bell pepper (<jats:italic>Capsicum annuum</jats:italic>) fruit were evaluated in a passively ventilated greenhouse, in soilless media trellised to a “V” system (two-stempruned plants) or the “Spanish” system (nonpruned plants) in flat bags or nursery pot containers; and densities of 1.5, 1.9, 3.0, and 3.8 plants/m<jats:sup>2</jats:sup> (0.14, 0.18, 0.28, and 0.35 plants/ft<jats:sup>2</jats:sup>), in a winter-to-summer-crop in Gainesville, Fla. The trellis systems did not affect total marketable fruit yields but production of extra-large fruit was higher (38%) in non-pruned than in pruned plants. Marketable fruit yields were similar in plants grown in bags and pots, and had positive linear responses to increased plant density. Not pruning reduced by half the percentage of fruit with blossom-end rot. Pruned plants produced 50% fewer flower bud supporting nodes than non-pruned plants but had a greater percentage of fruit set. Regardless of trellis systems, fruit set per plant decreased linearly as plant density increased. Overall, the “Spanish” trellis system at a density of 3.8 plants/m<jats:sup>2</jats:sup> resulted in greater yields of extra-large fruit and required 75% less labor than the “V” system to prune and support the plant canopy.</jats:p>

Forecasting Root-Zone Electrical Conductivity of Nutrient Solutions in Closed-Loop Soilless Cultures via a Recurrent Neural Network Using Environmental and Cultivation Information

“…Drainage ratios were maintained at 20–30% during experimental period. Plants were grown to maintain two main stems, which were vertically trellized to a “V” canopy system (Jovicich et al, 2004). …”

Fruit Quantity and Ripeness Estimation Using a Robotic Vision System

“…The roof was covered with white Polyweave reinforced polyethylene film. The sweet pepper, Red Jet cultivar which is a blocky fruit and red when mature, were grown in a soilless media production system aligned as a single row following practices reported in Jovicich et al [13]. The crop was arranged with plants distanced every 0.25 m and aligned in rows separated 1.45 m from each other.…”

Uso de portainjerto sobre el rendimiento, calidad del fruto y resistencia a Phytophthora capsici Leonian en pimiento morrón

“…Así su cultivo tiene gran aceptación por los productores, lo cual incrementa la superficie plantada cada año. En términos económicos, la producción de pimiento morrón es una alternativa de producción muy atractiva durante el ciclo otoño-invierno de cada año, lo cual se debe a su elevado rendimiento ya que puede alcanzar un precio mayor de hasta cinco veces comparado al ciclo de producción primavera-verano, sobre todo si se comercializa hasta que el fruto toma el color secuencial característico de la variedad (verde, amarillo, naranja, morado, chocolate, rojo) (Jovicich et al, 2004). Sin embargo, la incidencia de P. capsici, es un problema muy grande en el desarrollo de este cultivo, ya que este patógeno puede ocasionar pérdidas entre 10 y 100 % de la producción, razón por la cual muchas áreas de cultivo cambiaron de uso del suelo o el chile morrón se cultiva en sitios libres de la presencia de este patógeno (Sanogo y Ji, 2012).…”
