Cultivo de gladíolo em sistema de plantio direto orgânico

Abstract

The cultivation of cut flowers is considered an alternative for diversifying the property, especially in family farming. The culture of gladiolus (Gladiolus x grandiflorus Hort.) offers as resources ease of management, short cycle (60 to 120 days) and quick financial return. The traditional way of cultivating gladiolus is carried out with intense soil revolution, which can generate losses in the system. Thus, the adoption of systems has become important for the balance of agroecosystems, with the No-tillage System being one of these options. The objective of this work is to evaluate the agronomic performance of gladiolus in the organic no-tillage system. The experiment was carried out in the Horticulture sector of the Federal University of Fronteira Sul, Laranjeiras do Sul-PR campus. The cultivation of plants with forecast forecast in completely randomized blocks (Avena with forecast forecast) + pea without addition of cover blocks (Avena sativa L.) of the gladiolus crop. The gladolus cultivar used was Yester intermedia II. The estimates presented were: phenological and morphological characteristics of the crop, physical and biological characteristics of the soils, phytophagous insects, diseases and weeds, post-harvest viability and productivity. Higher basal soil respiration, soil temperature, weedy problems, total chlorophyll, rush length, leaf length, floral rush classification and similarity were significant differences between systems. The cultivation with ground cover obtained higher productivity. The satisfactory agronomic system being indicated for the cultivation of gladioli.
