Produção e qualidade de morangueiro sob diferentes concentrações de calda bordalesa, sulfocálcica e biofertilizante supermagro

Abstract

ResumoO trabalho teve como objetivo avaliar o comportamento agronômico e as alterações físico-químicas de morangueiros em sistema de cultivo orgânico em função da aplicação de diferentes concentrações de calda bordalesa, calda sulfocálcica e biofertilizante supermagro. O primeiro experimento foi realizado em 2007, com a cultivar Camarosa, em um esquema fatorial 3 x 5, sendo: o fator A constituído pela calda bordalesa, calda sulfocácica e biofertilizante supermagro; o fator B representado pelas concentrações de 0,5; 1,0; 2,0; 4,0 e a testemunha. No segundo experimento, em 2008, os tratamentos foram um fatorial 5 x 3, sendo: o fator A representado pelas caldas (calda bordalesa a 1%; calda sulfocálcica a 1%; biofertilizante supermagro a 4%, alternância de aplicação de caldas nas mesmas concentrações e a testemunha); o fator B pelas cultivares (Camarosa, Camino Real e Albion). As caldas bordalesa e sulfocálcica, bem como o biofertilizante supermagro interferem positivamente no número de frutos, massa média e produção do morangueiro. Concentrações acima de 1,0% de calda bordalesa e sulfocálcica causam manchamento dos frutos, limitando sua utilização. O supermagro não apresenta restrição, sendo que as melhores respostas agronômicas foram observadas nas maiores concentrações testadas. A aplicação das caldas e do supermagro interferem no controle de doenças com redução da severidade da mancha-de-micosferela na cultivar Camarosa.

The first experiment was conducted in 2007, with cultivar Camarosa, with a 3 x 5 mixed factorial, been: the factor A constituted of Bordeaux mixture, lime sulfur and fertilizer supermagro; the factor B represented by concentrations of 0.5, 1.0, 2.0, 4.0% and the control. In the second experiment, in 2008, the treatments were a 5 x 3 factorial design, been: the first factor represented by mixture (Bordeaux mixture at 1%; lime sulfur at 1%; biofertilizer supermagro 4%; alternating application of this mixtures at the same concentrations; and control); and the factor B by cultivars (Camarosa, Camino Real, and Albion).

Intercropping garlic in strawberry fields improves land equivalent ratio and gross income

“…However, the bulbs were weighed immediately after harvest without a curing process, while in previous studies, a curing process of 7 (LUCENA et al, 2016) or 25 days (BIESDORF et al, 2015) was carried out, which may have reduced the mass of the bulbs (3 to 10% reduction in bulb weight) (LIMA & RESENDE, 2007). The yield of the Albion variety of strawberry was similar to that obtained in a previous monocrop study in Dois Vizinhos, PR, County, in which values ranged from 319.50 to 386.50 g per plant (MAZARO et al, 2013) and were inferior compared to that obtained in Guarapuava in first cycle (784.3 g per plant) (ZEIST et al, 2019). For the Camarosa variety, similar yields were observed in studies conducted in Pouso Alegre -MG (137 g per plant) (PÁDUA et al, 2015) and Curitiba, PR Counties (117.70 g per plant) (LEMINSKA et al, 2014) and were inferior compared to that obtained in Guarapuava in first and second cycles (482.0 and 410.7 per plant for first and second cycles, respectively) (ZEIST et al, 2019).…”

Artificial vernalization in strawberry plants: phyllochron, production and quality

“…Other studies have also reported higher productivity for the Camarosa cultivar (Oliveira et al, 2009;, which demonstrates the productive potential of this cultivar in the soil and climatic conditions of Rio Grande do Sul. Mazaro et al (2013) working with the cultivars Camarosa, Camino Real and Albion in northern Paraná, better productivity results in Camarosa cultivar were observed with the worst being those for Albion.…”

Comparación de 2 formas de fertilización en cultivo de maíz variedad DK 7500, La Troncal-Ecuador

“…Alvarado Teyssier, R., et al, (2018) indica que existen opciones biológicamente sustentables que pueden sustituir parcialmente la fertilización sintética de los cultivos, disminuyendo los costos de producción e incrementa los rendimientos de grano. El super magro no muestra ninguna restricción, ya que las mejores respuestas agronómicas se observaron en concentraciones más altas probadas (Mazaro, S. M., et al, 2013).…”
