Evolução do sistema plantio direto de hortaliças no oeste do Paraná

Abstract

The Direct Vegetable Planting System (SPDH) focuses on conserving the soil and its characteristics, aiming to increase vegetable production, standing out as an alternative to traditional systems. The objective of the work is to evaluate the adaptation of ground cover plants and the evolution of vegetables throughout the first years of SPDH in the western region of Paraná. The experiment was conducted in the agricultural area of the Federal Technological University of Paraná (UTFPR) Santa Helena campus, using 8 treatments and 3 replications, namely: Crotalaria Ochroleuca (Crotalaria ochroleuca), Crotalaria Spectabilis (Crotalaria spectabilis), Millet (Pennisetum glaucum), Pigeon Beans (Cajanus cajan), Pork Beans (Canavalia ensiformis), Mucuna Preta (Mucuna aterrima), Fallow with mowing and Fallow with turning. A compilation of results related to the production of cover crops was carried out, as well as the productive responses of broccoli and zucchini in SPDH between the years 2021 and 2023. The study identified the benefits of each cultivation system for these crops based on experience in SPDH compared to conventional management. Positive effects were discovered regarding an increase in the production of broccoli and zucchini on conservation management systems, in particular the use of legumes such as jack beans, which tripled broccoli productivity compared to the conventional planting system.
