“…These results are in accordance with those obtained by Derpsch et al (1985) and Santos et al (1994b) who studied soybean cultures under different tillage systems after black oat covers. In addition, Kluthcouski et al (2000) observed the same between different tillage systems.…”

Nowadays, agricultural practices should combine high yields with a sustainable use of resources. Different tillage practices and crop covers, if combined, may help to achieve both objectives. In this work, several traits of a soybean (Glycine max L. Merr) cultivar were studied under different conditions of tillage and previous soil coverages. The experiment was installed at Lageado Research Station, Botucatu county, SP, Brazil, on a Paleudult. It consisted of nine treatments (combining three systems of soil tillage and three cover crops) and 4 replicates, yielding 36 plots of a randomized block experimental design. The soil tillage systems considered were: (i) conventional tillage with two heavy harrowing and a levelling harrowing; (ii) chiseling, and (iii) no-tillage with chemical drying of vegetation. The three cover crops used were: black oat, sorghum and spontaneous vegetation. Analyzed variables were: plant height, initial and final plant densities, height of first pod insertion, weight of a thousand grains, number of pods per plant, number of grains per pod, and crop yield. No significant differences were observed for most of the analyzed variables; however, conventional tillage produced significantly heavier grains and a higher number of pods per plant. The selected covers were considered an excellent coverage prior to planting soybean in a crop rotation. The three tillage systems can be used for deployment of culture without compromising the development of soybean.Additional key words: black oat, chisel, Glycine max, heavy harrow, sorghum, yield. ResumenEfectos de diferentes sistemas de laboreo del suelo y coberturas vegetales sobre la cosecha de soja en la región de Botucatu en Brasil Actualmente, las prácticas agrícolas deben combinar elevadas productividades con un uso sostenible de los recursos. Diferentes sistemas de laboreo y coberturas vegetales, combinados, pueden ayudar a conseguir ambos objetivos. En este trabajo se han estudiado diversos aspectos de un cultivar de soja (Glycine max L. Merr) sometido a diferentes condiciones de laboreo y cobertura vegetal. El experimento se llevó a cabo en la Estación Experimental de Lageado, Botucatu (São Paulo, Brasil) sobre un Paleudult, y constó de nueve tratamientos (tres sistemas de laboreo y tres coberturas vegetales combinados) y cuatro repeticiones, totalizando 36 parcelas con un diseño experimental en bloques aleatorios. Los sistemas de laboreo considerados fueron (i) laboreo convencional con dos gradas pesadas y una niveladora; (ii) escarificado y (iii) no laboreo con desecación química de la vegetación. Las tres coberturas utilizadas fueron la avena negra, el sorgo y la vegetación espontánea. Las variables analizadas fueron altura de las plantas, densidad inicial y final de plantas, altura de la inserción de la primera vaina, peso de mil granos, número de vainas por planta y de granos por vaina y productividad de la cosecha. No se observaron diferencias significativas en la mayoría de las variables; sin embargo, el laboreo convencional produ...

“…These practices are indispensable for the development of stable agriculture in terms of sustainability. Santos, Ignaczak, Lhamby and Baier (2000a), Santos, Ignaczak, Lhamby and Carmo (2003), Santos et al (2007), Santos, Spera, Fontaneli and Dreon (2011), showed that crop rotation systems are more energy-efficient and should be preferred instead of crop succession. The authors observed that cover crops tend to have a low energy performance, reducing the input of fossil energy into the systems.…”

The production system model that has been adopted in most Brazilian regions, the soybean/second corn crop succession, has led to problems in water and soil conservation and favorable conditions for diseases, pests, and weeds in the agricultural system and, consequently, increasing its energy use. Crop rotation is an alternative to this production model, directly interfering with the problematic aspects of the crop succession system and, consequently, its energy balance. Therefore, this study aimed to identify the crop rotation system with the best energy balance and efficiency. The data on the quantity of inputs (seeds, fertilizers, pesticides, and fuel), labor, and grain yield used in the study were collected from a crop rotation experiment conducted at the experimental station of the Rural Development Institute of Paraná - IAPAR-EMATER, Londrina, PR, Brazil, from 2014 to 2020. The experimental design consisted of randomized blocks, with six treatments and four replications. The treatments consisted of T1 (second corn crop/soybean), T2 (white oat/soybean, triticale/corn, and wheat/soybean), T3 (rye + black oat/soybean, black oat + fodder radish/corn, and congo grass/soybean), T4 (canola/corn, crambe/corn; canola/soybean); T5 (buckwheat-fodder radish/corn, bean/soybean, and buckwheat-white oat/ soybean), and T6 (wheat/corn, canola/corn + congo grass, and bean/soybean). The different crop rotations and the traditional second corn crop/soybean system provided positive energy balance and efficiency, that is, they produced more energy than they consumed. The canola/corn, crambe/corn, and canola/soybean rotation systems had the highest energy balance and efficiency, with values of 866,442.27 MJ ha−1 and 10.27, respectively, mainly due to corn cultivation in the summer, which resulted in a higher energy return than the other grain-producing crops.
